Febres Cordero | A new hybrid building in the historic center of Cuenca

Category: ⚐ EN+architecture+ecosistema urbano+mixed-use building+sustainability

Vista aerea febres

The Febres Cordero building was developed within the scope of CUENCA RED, the urban reactivation strategy for Cuenca, Ecuador. The aim of Cuenca Red was to incorporate activities and programs in the Historic Center in order to create a new network of reactivated public spaces. One of those spaces is Febres Cordero, an emblematic and historical building which had functioned as a school for decades.

This building has great heritage value and has one of the largest courtyards of the entire historic center (3,300 m2). It is located on Gran Colombia Street, right next to the tram line. It is comprised of two main volumes, one of them  with much less quality and architectural interest.

The building was going to stop its activities within a few months of the beginning of the project, as the school was going to be relocated into a new building. Also, the school has been an important node of social and economic activity for years on the area. This large community injects daily activity into the center of Cuenca.

Activity from the beginning

One key aspect of the project was not only to design a building with new uses and programs, but also to plan the transition process between one moment and the other. We conceived the project from its Phase 0, in order to unleash, through different actions and activities, dynamism and interest in the future of the building and its interior space.

Space is activated from the beginning, dividing the construction into 3 phasesThe project is planned in 3 phases. The first one is really important, consisting of the opening and reactivation of the central courtyard as a public space for events and activities. This phase is esentially low cost, but its implementation will have a strong impact in keeping momentum and activity around the area, and also generating interest and expectations around the building. Subsequently, the reconditioning and construction of the building will be carried out, and finally the climatic conditioning of the new interior square.

In search of new uses

Following our conclusions of the urban analysis, we noted the progressive emptying of housing in the Historic Center of Cuenca. Although the center still continues to be an active space for tourism and commercial activity, the number of residents is decreasing, moving towards the perimeter of the city center.

This is certainly a problem, especially in the afternoon or the evening, when the shops and offices close, and the lack of activity and people in the area becomes more evident. That emptiness generates unfavorable conditions, like sense of insecurity, or an increase in the number of abandoned or underused properties.

It was also key to generate conditions for other families to consider attractive and feasible to live there. The inhabitants of the CHC and technicians who participated in the participatory process agree that the building has optimal conditions to become a new “catalyst” of the city. The Febres Cordero building can be reconstructed as a pilot project that will address many of the opportunities and challenges shared with other historic centers in Latin America.

A hybrid architectural complex

Febres Cordero does not only house a school, but also commercial premises along the ground floor. The project aims to enhance this aspect, creating a hybrid building capable of bringing together different programs, generating a diverse community that serves as a reference for social and economically sustainable urban intervention.

The rehabilitation of the Febres School seeks three main goals, as steps towards the improvement of the Historic Center:

  • Increasing the extension of public spaces in the area
  • Providing diverse housing typologies (including social housing)
  • Generating a new heart of urban activity through the insertion of new facilities.

Hybrid program of the new complex

To achieve this, Febres Cordero comprises 3 components:

  • Rehabilitation of the existing heritage building (4.500 m2) with new apartments, students dormitory, commercial ground floor, common workspaces, rest area and an elevated outdoor public space.
  • Construction of a new building (5.000 m2) on the surface freed by the demolition of the unprotected building. It is mainly residential and will also have a series of additional services and facilities that are of a public nature and therefore accessible to the rest of the inhabitants of the complex.
  • Reconfiguration of the inner courtyard as a new public square for the city (3.300 m2).

The new building is connected to the heritage building by corridors

A new public square

The courtyard is conceived as a new public square for the city. It recovers the entrances from the 3 adjacent roads and generates an active and attractive, programmable public space. The ground floor will be adapted to reinforce this idea, promoting permeability and the visual connection between the streets and the courtyard.

The proposed square includes two conditions: a flexible space with a mobile grandstand that allows the creation of different configurations for cultural and sport events, and a more natural space, a cuencan garden inspired by the multiple existing green patios that together create a network of vegetation and biodiversity in the historic center.

Respecting heritage

We are aware of the historical value of a building like this. After a careful study of the history, typology, and construction of the building (built around 1900), the intervention was designed to preserve and respect its historical value and at the same time to introduce new structures to diversify the possibilities of use and adapt it to the evolving urban context.

The intervention respects and seeks to value the intrinsic qualities of the building, and also wants to create a dialogue with the most innovative construction techniques.

Architectural plans of the refurbished complex.The main strategy consists of concentrating the utilities or technical systems of the apartments in spines perpendicular to the façade line. This way we can  to minimize the impact on the façade and generate cross ventilation in all the rooms. The exterior façade is not altered by any of the interior interventions and will preserve its current structure and image towards.

On the other hand, the roof was in poor condition. Activating the space under the roof with the creation of a new housing ring towards the interior of the patio enabled us to expand the useful surface without impacting the building on its exterior appearance and its relationship with the public road.

Maximum sustainability

In a project as ambitious as Febres Cordero, the most appropriate technical mechanisms must be sought to achieve maximum economic, social and environmental sustainability. The final design and construction systems were devised under the following sustainability criteria: following bioclimatic design principles for better energy efficiency, adopting local materials and construction techniques to improve durability, and considering the economic impact of the construction at a local level.

The rehabilitation of Febres Cordero is also conceived to be financially sustainable, allowing a short-term return of the investment with the sale and lease of housing and commercial premises, and with the generation of new economies in the urban area.

In general, this rehabilitation project, a pilot within the general Cuenca Red plan, will increase the intensity of use, the possibilities of social interaction and the generation of economies that contribute to the long-term sustainability of the historic center.

A starting point: Banco de Ideas as an activator of the Hermosillo center

Category: ⚐ EN+architecture+ecosistema urbano+mixed-use building+sustainability+urbanism

In a previous post, we shared the general approach for the Revitalization Plan of the historical center of Hermosillo. Pointing out how a strategic-tactical approach can contribute to transforming the city.

As we are focusing this month on hybrid buildings and urban catalysts, we want to take a closer look into one of the key sub-projects of the Plan Idea Hermosillo: the Banco de Ideas (Bank of Ideas).

Identifying an opportunity for activation

During the mapping process of the historical center, both in the on-site surveys and in the participatory meetings and workshops, one of the locations began to stand out as a key spot in the project’s approach: the Banco de Ropa (bank of clothes), a two-storey building used by a local NGO as a collection, storage and re-distribution point for second-hand clothes.

Many of the ingredients needed to launch an urban activation project are present on the Banco de Ropa:

  • It is strategically located in the center of the intervention area (see map). On the main street, near an important intersection and with direct views of the Cerro de la Campana. This location gives the project an excellent level of visibility and maximizes its potential impact on the urban center.
  • It presents an interesting combination of building and public space. Two of its facades, equipped with large sliding doors, face different streets, one of them with a small square in front. Right next to it, there is a vacant lot currently used as a parking lot. This combination of spaces creates the ideal situation to experiment with interior and exterior urban interventions.
  • The size of the building—around 1,700 m2—and of the surrounding spaces are also ideal, keeping the intervention in an affordable range but allowing a significant level of impact to be achieved in its surroundings.
  • The building is the only public property in the area, which enables some approaches that would not have been possible on a privately owned lot.
  • Transferring the existing use—as a clothing ban—to another location was deemed feasible and even desirable.
  • During the workshops and meetings, several local agents expressed their interest in taking part in the activation of the Banco de Ideas from the socio-cultural and business side. The building is seen as a possible hub for entrepreneurship, gastronomy, and technology, incorporating an educational component in its core.
  • The building’s general construction quality is relatively low, but on the other hand offers great potential for reconversion, being able to function as a large container of activities.

All these factors give this location a great potential for transformation and positive impact on the environment. They enable the ability to activate spaces, attract people and become the first step towards the revitalization of the historical center.

This is why this location was chosen as the main intervention of the Plan Idea Hermosillo, being developed as the “Banco de Ideas” Pilot Project.

The Banco de Ideas as an urban catalyst

The name and identity of the Banco de Ideas establish a link between its current use as a clothing bank and future use as a cultural, social and economic incubator. It is a space of exploration, a place capable of kick-starting the social, cultural and economic activation of the area. Capable of functioning as a collaborative “kitchen” in which the city and the neighborhood can experience new activities and ways of organizing themselves, and launch initiatives that improve the quality of life.

This is the role of an urban catalyst: to be one of the first steps on the long process of revitalization of an area of the city. The aim is to create a public and open place that would become a new node of activity, achieving a high impact without consuming excessive economic resources.

Diversifying uses

One of the first considerations when conceiving a new urban space like this one is the incorporation of new uses and programmes that will guarantee its transformation into an attractor of activity.

Many of the proposals emerged during the participation process with different stakeholders. The activities also served to identify the people or groups that could be involved in the subsequent management of the space. The uses and programmes that were identified as relevant for the reconversion of the building included gastronomy, culture, and heritage, entrepreneurship, education, new technologies and sport.

Maximize the relationship with the environment

The Banco de Ideas building is a visual reference for the entire area because of its solid volume and height. It can clearly be seen from the Cerro de la Campana. However, given the importance of its integration into the urban context, the intervention cannot be restricted to an isolated architectural project: it needs to engage with the surrounding environment.

In the adjacent outdoor spaces (the small square on Obregón Avenue and streets) interventions are proposed in order to improve usability, comfort, attractiveness and general quality of the space.

The location of the building (right next to a public parking lot surrounded by a historic façade) allows for the creation of a unique combination of interior and exterior spaces. The parking lot is incorporated as a temporary expansion space in the moments of low usage, making it possible for the Banco de Ideas to also program outdoor activities.

The four large opposite entrances facilitate themovement of people, furniture and large objects, and provide physical and visual connection through the building.

The project

The concept of an urban catalyst is translated as a hybrid building (see more examples), capable of hosting a wide variety of uses. This building typology lies halfway between the closed and the open, the public and the private, the physical and the digital.

The project is based on the existing building, modifying it according to six key principles: the creation of multifunctional spaces, the connection of interior spaces with surrounding public spaces, the improvement of its climatic comfort by bioclimatic design, the integration of new facilities and technologies to prepare it for innovative uses, the creation of an open and inclusive management system, and the extension of opening hours to create an almost 24/7 facility.

Inside the building, the intervention focuses on improvements that will allow new programmes and increase comfort: more natural lighting and ventilation, an adaptation of the space to new needs, improved accessibility, modernization of basic infrastructures, improvements in the perception of the space, etc.

A central patio combines vertical communications, lighting and ventilation. Three open floors are created, with a flexible distribution aided by furniture and light walls.

A key action for the renovation of the building is the addition o a new façace, made with light structures and semi-opaque textiles over the existing façace. Its design allows, on one hand, to protect the structure and the main enclosure of the building from direct solar radiation, improving its climatic behavior. On the other hand, brings a renovated image to the building while maintaining part of its previous shape.

The key to a sustainable management

One of the main challenges is related to the reactivation and management model of the Banco de Ropa building. Improving its physical appearance or incorporating new programmes is not enough. The real challenge is to develop an ad-hoc management model that guarantees its economic feasibility and at the same time promotes its use as a public facility.

This is why it is necessary to have the support of different urban stakeholders (private entrepreneurs, civic associations, local institutions, foundations, NGO’s, volunteers, etc.) organized in an administrative and consultive committee, and a civic board that will operate the Banco de Ideas in its day to day functioning.

The public sector will provide the building on a concession basis and will provide resources for the initial materialization of the physical infrastructure. At the same time, it will facilitate its management and operation with the other public agencies involved.

This management model is based on good practices from different parts of the world, such as Estación Indianilla (CDMX, Mexico), Cascina Cuccagna (Milan, Italy), Infante 1415 (Santiago, Chile), Chapitô (Lisbon, Portugal) or the Scuola Open Source (Bari, Italy).

The aim is making the Banco de Ideas a self-sufficient project that generates its own economy and activity.

Unveiling the latest images of the Banyan Hub | A project for a new Hybrid Building in West Palm Beach, Florida

Category: ⚐ EN+ecosistema urbano+mixed-use building+sustainability+work in progress


After winning the international competition Shore to Core, commissioned by the West Palm Beach Community Redevelopment Agency (CRA) and organized by the Van Alen Institute in 2017, Ecosistema Urbano is developing several parts of the proposal, among them the visionary Banyan Hub building.

The Banyan Hub project arises from the intuition of the City of West Palm Beach and the CRA to transform the existing Banyan Garage, a car-devoted building from the 70s in the heart of the Downtown, into a new opportunity to activate the city, a hub for dozens of new activities for both residents and visitors.

Ecosistema Urbano has finalized the Schematic Design of the project that has been officially approved by the West Palm Beach City Commission on Oct. 22. The project will be further developed in the next months.

The Banyan Hub in the surrounding context of West Palm Beach.

A hybrid and flexible building open day and night
The Banyan Hub offers in a single building a wide range of different programs, from open and public spaces to reserved and private areas. The wide variety of possibilities that the building brings will have an important impact on the way of living in West Palm Beach Downtown. The programs collaborate with one another, creating a public facilities machine in which each part works separately, but all of them work together to offer the user a superb experience of public-private spaces. The program includes urban plazas, retail and catering, rooftop pavilion, YMCA, business hub, mobility hub, housing, and city support area.
Sustainability and bioclimatic design are key ingredients of the Banyan Hub, that is strongly characterized by its breathing façade, two courtyards, and multiple active and passive climatic devices.

Urban bioclimatic plazas: expanding public space possibilities and multiplying them by 3
The public heart of the Banyan Hub beats on the three public plazas located on different levels:

  • A flexible and permeable plaza at ground level, with an open hall connected to the surrounding streets and to the rear passageway, that integrates retail, catering and several support spaces.

  • A covered open-air plaza at an intermediate level for temporary events, including spectacular features such as a digital interactive waterfall or a green courtyard, or local programs as the farmers market.

  • A top terrace, overlooking the lagoon offering a panoramic view of the unique Floridian natural environment and of the whole Downtown. The terrace accommodates a civic pavilion to host civic events (public meetings, projections, performances) as well as private events such as weddings.

Celebrating at the Banyan Hub Rooftop Terrace.

Interconnected public spaces
The three main public spaces will be connected to provide the experience of having a chameleonic journey through different environments. The Downtown is connected to the middle level elevated urban plaza through an exterior escalator that dynamizes the façade on Banyan Blvd., allowing to stop by the retail ring at the first two levels. From the elevated plaza, it will be possible to go up to the terrace using the breathtaking helical ramp around the green courtyard.

Banyan Hub Bioclimatic Design | A green living building.

A building green in the middle
Other uses in the central block of the building are the Business Hub and the YMCA, each of them occupying two levels. Both areas feature the presence of the central green courtyard, an open-air multi-level natural space that gives continuity to the landscaped urban plazas of the building. Moreover, the green courtyard has a relevant passive bioclimatic function as it would help to reduce temperatures by up to 5ºF and regulate ventilation, providing pleasant environmental conditions throughout the year while reducing environmental impact and management and operational costs.

Business Hub | Working at the Banyan Hub in close connection to nature.

A breathing skin
The façade acts as one of the main conditioning systems of the building, filtering the direct sunlight and regulating ventilation. It is formed by an array of individual elements that present a responsive behavior, autonomously sensing the climatic conditions and the needs of the building and changing their configuration. Protected by the external shading, there is a green buffer zone, mainly comprised of a permeable structure holding vegetation and supporting varied activities. This space acts as a second natural filter for light and breeze and contributes to the regulation of the internal temperature through evaporative cooling.

YMCA at Banyan Hub | Exterior running track at 113’ at Banyan YMCA.

Living overlooking the lagoon
The upper block of the building is dedicated to housing. The residential units face out to the exterior, enjoying privileged views of the city and the lagoon. A modular system allows for the combination of units of different sizes, ranging from 500 to 1500 sq.ft. Limited living spaces of micro-units are compensated by indoor and outdoor common facilities, specifically conceived to foster the sense of community of residents. Residential units are arranged around a shared courtyard, where vegetation will help to refresh the interior micro-climate, maintaining the appropriate temperature and humidity levels to achieve comfort for users.

Making an invisible parking
The Banyan Hub will continue to serve as a municipal garage for the city’s needs, as its functioning is crucial to parking management of West Palm Beach Downtown. However, the parking will be completely upgraded using an Automated Parking System technology. With this system, the required 350 parking spots will occupy only the ⅔ of the volume currently used by the existing Banyan garage. Moreover, as the ambition of the Banyan Hub is to be an active piece of the city that projects its active life towards the surrounding context, a specific solution has been designed to ensure that the uses along the façades reflect the dynamism of the building. The 4 levels of parking are enclosed at the very core of the building, completely hidden from the outside; these are surrounded on 4 sides by two levels of retail and catering connected by a public corridor that gives architectural quality to this space while activates it.

About West Palm Beach Community Redevelopment Agency
Created in 1984 and authorized by Florida’s Community Redevelopment Act of 1969 (F.S. 163, Part III), the West Palm Beach CRA is nationally recognized as one of the most innovative and effective Community Redevelopment Agencies (CRAs) in the country and is setting the standard for redevelopment. The downtown core has gone through a rebirth with substantial private investment including commercial and residential development. Public investment dollars total in the millions with a state-of-the-art library, revitalization of the historic Sunset Lounge, streetscape infrastructure, and an enhanced waterfront. The CRA continues to coordinate with the City and other agencies to market and revitalize the downtown.

An Overview to our Latest Projects in Latin America

Category: ⚐ EN+architecture+Centro Histórico Abierto+city+Cuenca Red+ecosistema urbano+Plan CHA+Plan Encarnación Más+sustainability+technologies+urbanism

During the last year we have been busy with several projects and competitions (including the latest Open Shore project for West Palm Beach) which didn’t give us the time to look back and reflect on some of our projects from the last few years.

As maybe some of our readers know, Ecosistema Urbano has been working on several large-scale projects in Latin America since August 2014 when we won a competition to develop the Master Plan of the Historical Center of Asuncion, Paraguay. In 2015, we accomplished another significant project: the participatory process Centro Histórico Abierto for the transformation of the historical center of Distrito Central, capital of Honduras. We also worked on the transformative Cuenca RED project which acted on the Public Space Reactivation Plan of the Historical Center of Cuenca, Ecuador. After the first experience in Paraguay, we had another project in the city of Encarnación, giving origin to the Plan Encarnación Más, composed by an Urban and Territorial Planning and Sustainability Plan.

In these four cases, the urban issues and the peculiar situations that required our intervention were distinct yet shared many common features. More specifically, the enthusiasm and interest shown by the people directly and indirectly involved was apparent throughout all of the projects, but also the opportunities that these experiences have given us as an architecture firm, to test ideas, tools, and methodologies.

CONTEXT

Although they share the same area of origin, each of these cities has developed unique problems and issues. Some of these, such as the ones found in Encarnación, are physical-territorial matters such as the recent loss of the city center because of the controlled rise of the water level in the Yacyretá dam. That event led to the envisioning of a “Sustainable Development Plan” and  “Urban and Territorial Ordering Plan” in order to prepare the city for the future. In the case of Cuenca, the need for a new plan was determined by a series of big changes underway: the definition of a new model of mobility and the progressive emptying of population that afflicts the historical center, World Heritage Site since 1999, and headquarters of most of the commercial, touristic and economic city’s activities. In the case of Asunción and of the capital of Honduras, the project regards the transformation and the regeneration (both physical and social) of their historic centers. The Distrito Central is part of the development framework of the new urban axis “Choluteca River”.

SOCIAL

1 – Participation

The first of the projects’ common keys are connected with the theme of sociability, expressed in the form of participation. The citizens’ involvement, promoted both through a series of organized activities and through online platforms, has been one of the cornerstones of our work in Latin America. We involve citizens because we believe that the citizen is the only force able to achieve a deep and lasting change in the urban environment and so they should not be just a passive receptor of the changes promoted by the city’s institutions. That’s why in some cases, as in that of Asunción with the ASU-LAB, a space was created which could serve as an interface between citizens and institutions: a place for the execution of the city planning but also an open place where each person or group can drive a new regeneration initiative or attend a course.

Organized activities with the citiziens

Organized activities with the citizens

Participatory activities, such as workshops and events, have been geared to address representative members of the city such as children, university students, “active agents”, citizens and institutions. For each of these categories we have developed, project after project, a series of ad hoc initiatives.

Participatory process in Asunción, Encarnación, Cuenca and in Distrito Central

Participatory process in Asunción, Encarnación, Cuenca and in Distrito Central

For the children we created a “toolkit” with which we had them reflect on their perception of the city and with which they could propose their ideal vision for the city. The kit consists of portions of the city map on which they could draw and that, once recomposed, could recreate the overall image.

2 – Urban actions

These activities were followed by a series of urban actions so that the results could be shown tangibly in the city. In the case of Distrito Central, ideas were gathered in a week of workshops with 80 students from the three major universities in the city and have been translated into urban actions like “Las Gradas de la Leona“. The staircases are indispensable spaces in a city with a very distinct topography as Tegucigualpa. But in the city these vertical connections are often perceived as inhospitable, dangerous, and dirty places and therefore they are cut off from any kind of activity. The students’ work was aimed at legitimizing these stairs as a public space through cleanliness,  decor,  lighting, and the organization of a series of activities that achieved resounding success and participation.

Socialization along "Las gradas de la Leona"

Socialization along “Las gradas de la Leona”

In the case of Encarnación, one of the proposals that has distinguished our approach in this project was the inclusion of a series of pilot projects that accompany and translate into concrete proposals within the “Plan de Desarrollo Sustentable” and the “Plan de Ordenamiento”. Among these, one of the most successful pilot projects was the “Proyecto Piloto Bicisienda“, whose purpose is to improve the quality of life of the inhabitants by optimizing the use of alternative mobility and by raising awareness of the value of sports and recreation. Again we have sought the cooperation of citizens by promoting a series of initiatives (such as the construction of bike lanes in the city) in which the citizens could feel protagonistic.

3 – Informative events 

The disclosure of the participatory process to the citizenship, promoted both online through the project’s platforms and through open exhibitions, is a recurring phase in all four projects. We felt it important and necessary that each phase of the process was documented and could be easily accessible to all so that the citizens could be informed about the progress made in the project. Among these, the most scenic event, realized in Tegucigualpa, Cuenca and Encarnación, was the creation of a ” mosaico ciudadano“, a wall made of post-it notes with written words, phrases, and ideas about the city.

SUSTAINABILITY

Another theme of our projects in Latin America is sustainable development expressed in various forms: care and attention to the environment, the introduction of an alternative mobility system, the importance of education to the environment as an engine of sustainability, and the development of the project made in collaboration between private initiatives and institutional management. In the case of Cuenca, for example, our intervention was partly required as a consequence of the municipality’s willingness to define a new model of mobility for the historical center of the city consisting of ceasing car traffic in the center and building a new tramway system. This new model of mobility has direct implications for the current urban dynamics, as well as on the public space, as it tries to reduce the vehicular load of the city, giving priority to pedestrians and cyclists. This, and the creation of quality public space, led to strengthen the social, economic, and cultural role of the city’s historical center making it more pleasant for residents and locals. Our aim is to activate a historical center that promotes social, economic, and environmental development, as well as a more livable, habitable, and inhabited historical center.

Cuenca’s plan is divided into four aspects: an urban acupuncture strategy, which proposes small / medium-scale interventions to recover areas with potential; a development of a network of active courtyards, by transforming the typical patios of Cuenca in catalysts capable of generating new synergies, connections, and interactions between residents, visitors and inhabitants; a guide to the historic center re-design, which defines the main lines for the design of the public space; a process of socialization, to define the “acopuntura” and the active patios network strategies. The intervention strategy in the square “Mary Corilè” in conjunction with the creation of “La casa en el árbol” is part of the active patios network strategy. This square is an unused and degraded space, perceived by the residents as an unpleasant and dangerous place.

The square "Mary Corilè"

The square “Mary Corilè”

Among the several interventions proposed, such as the re-furnishing of the square, traffic closure, and the design of activities in collaboration with the municipality, there’s also the creation of “La casa en el árbol“, a space included in the existing trees of the square where educational activities in relation to the theme of the environment can be carried out. “La casa en el árbol” is set up as a space to get in contact and be familiar with the nature, built in harmony with the surroundings. Inside there are several “environmental” classrooms in which one can study natural resources such as sun, wind, and water. More specifically, one can study: a system of photovoltaic panels that generate the energy needed for the lights, rainwater harvesting structures, and urban gardens as environmental and ecological experiences for schools and kindergartens. It is, ultimately, an open classroom in which a new form of pedagogy built on the respect for the environment is proposed, in order to increase awareness of the natural resources and of their use, as well as increase awareness of existing technologies.


In the case of Asunción we proposed a strategic plan with ten actions in order to promote a connection between the several parts of the city through the development of spaces, named “corridors“, and of individual buildings, named “urban catalysts“, which might act as drivers of change and benchmarks within the city. The corridors are divided into three types: those “green“, which introduce a new green infrastructure in specific parts of the existing roads; those “civic“, which consist of a new network of public spaces along the roads in order to connect the most important historic and government buildings; those “dynamic“, aimed at creating active urban environments and encourage economic and cultural activities.

Configuration of a charateristic dynamic corridor

Configuration of a charateristic dynamic corridor

Among the actions of Asunción strategic masterplan one concerns the economic and landscaping regeneration of the “Green Active Coast”. Due to its topography, this area is subject to cyclical floods because of the rising water level of the Paraguay River. That forces the inhabitants of the informal settlements who live there to move temporally. While fully respecting the identity of the river and of the existing topography, we have proposed the creation of a green lung with a large sports area in continuity with the Bicentennial Park. We also promoted the integration of the informal settlements both within the urban fabric and in the areas of new urban expansion.

The Encarnación masterplan incorporates within its own name the concept of “sustainability”, since it is composed of the “Plan of Sustainable Development” and of the “Plan of Urban and Territorial Organization”. The “Plan of Sustainable Development” will establish the standards and mechanisms for the growth and for the future development of the city according to the criteria of sustainability. The “Plan of Urban and Territorial Organization” aims at directing the use and the occupation of the territory in the urban and rural areas of the municipality. Officially, the city will face in the next twenty-four years an increase of the population amounted to 62,000 people, for whom it will be necessary to provide a massive increase in housing. The model we proposed to face this need refers to the sustainable principle of “the compact city.” Through the identification of a physical border for the city’s urban growth, we have protected the rural areas from new settlements. Moreover, we encouraged, through private and municipal initiatives, the densification of areas already developed, by filling the vacant urban lots and expanding pre-existing single-family homes.

The new interventions follow the principles of the bioclimatic architecture: large overhanging roofs and vegetation as protections from the hot summer sunlight, the use of wind to moderate the hot and humid climate of Encarnación, the reuse of rainwater, and the increase of the vegetation to absorb CO2 emissions.

TECHNOLOGY

In all four projects, technology represented an important collaborative tool to promote our work and to enable everyone to be constantly updated on ongoing progress, but also as a support for the participatory process, so that the involvement of the citizens would not be exhausted with the end of the activities organized, but could continue to map needs, issues, concerns and initiatives for those interested.

For this reason we have developed a platform, called Local-in (formerly What if ..?), which has been adapted to each project according to their personality and to the peculiarities of each participatory process, while maintaining a common format. Local-in is a free and accessible to everyone application of collective mapping. In it, registered users can add messages, photos and geolocalised links, sorting them into categories and labels. It’s easily installable and customizable, in perfect harmony with the spirit of the projects themselves, and it can be found for each project under the name “AsuMAP” for Asunción, with the name “Encarnación Más” for Encarnación, as “Cuenca RED” for Cuenca and with the name “Centro Histórico Abierto” for Distrito Central.

Open Shore Project for West Palm Beach | #1 Strategy to Trigger The Change

Category: ⚐ EN+competitions+ecosistema urbano+sustainability+urban social design+urbanism+work in progress

As we announced a few months ago in our previous post,  our project Open Shore is the winning proposal of Shore to Core international competition.

Open Shore is a complex project that addresses many different topics in an effort of providing solutions to several challenges that the city of West Palm Beach shares with many other cities. For this reason, we decided to present more in detail our project in a series of 3 posts dedicated to the three main points of the proposal: #1, Strategy to trigger the Change; #2, Waterfront: celebrating unexpected public space; #3, Banyan Hub: a city into a building.

Before going into detail of our proposal, it would be useful to introduce the context of the city of West Palm Beach.

As reported in the Shore to Core Competition Website, West Palm Beach is a young city that is growing quickly. Many associate this region with a large retirement community, but there is also a growing population of people in their 20s and 30s, as well as large Black and Hispanic populations. The city’s downtown and 10-mile waterfront present an opportunity to develop new amenities that reflect the city’s emerging populations, and design is a crucial tool for tackling these evolving needs.

The design competition asks: How can we reimagine our downtowns to make them more engaging and vibrant? How can cities collect information that informs future adaptation and growth?  How can we facilitate social interaction among diverse groups? How can the built environment improve residents’ physical health,  mental health, and social capital? 

Today we present the first post of the series, starting the narration of this exciting experience. This first chapter introduces the previous analysis and the general strategies that informed the design of the project areas.

Ecosistema Urbano wins West Palm Beach Design Competition!

Category: ⚐ EN+⚐ ES+⚐ IT+architecture+city+competitions+design+ecosistema urbano+news+sustainability+urbanism+work in progress

We are very happy to announce that our project Open Shore is the winning proposal of Shore to Core, the international design competition to reimagine downtown West Palm Beach as a dynamic, resilient waterfront city! We are thrilled with the great reception that the project has had, and eager to continue its development side by side with the people and the institutions of West Palm Beach.

Here we share the press release from Van Alen Institute:

Van Alen Institute and the West Palm Beach Community Redevelopment Agency (WPB CRA) today announced Open Shore by Ecosistema Urbano as the winning proposal for the Shore to Core waterfront design competition. The Shore to Core competition invited international designers, planners and architects to envision what the future of the West Palm Beach waterfront could look like over the next 20 to 30 years, taking factors including populations, economies and the environment into account. The winning proposal will serve as a “vision board” for the city’s future, providing a starting point and framework to help the city adapt and make the most of the waterfront.

Selected from a pool of over 40 international teams and two finalists, Ecosistema Urbano’s winning proposal envisions a healthier and more resilient downtown and waterfront for West Palm Beach—a keystone city in southern Florida with a growing population of people in their 20s and 30s, as well as large Black and Hispanic populations. The competition proposals imagine new amenities that reflect the city’s emerging populations, and Shore to Core’s organizers believe that design is a crucial tool for tackling these evolving needs. The initiative included public consultation, and this input played a role in the jury’s decision-making process.

Ecosistema Urbano’s winning design answers Shore to Core’s call for a comprehensive, forward-thinking urban plan to make West Palm Beach’s waterfront a year-round destination for locals and visitors alike. The proposal includes what could be the first public bioclimatic domes in the U.S. adorned with hanging gardens. These domes create climatically comfortable spaces 365 days a year, thereby supporting a more socially cohesive city.

The proposal also illustrates how the city’s Banyan Garage could be upcycled into a mixed-use building with both public- and private-sector roles featuring adaptive climates suitable for a range of activities, including a farmers market, coworking spaces, and skyline viewing platforms. Additional amenities include vibrant thematic alleyways—with such features as a rock climbing wall, interactive exhibition space, and immersive foliage—that harness the cultural values and experiences unique to West Palm Beach, while also providing shade and introducing new elevated programming spaces

Ecosistema Urbano will present their proposal to the WPB CRA board in May 2017. The CRA board will identify priority projects within the Banyan Garage and downtown alleyways, and then contract with Ecosistema Urbano. This process will be followed by outreach to the community about the individual elements that are scheduled for possible implementation in late 2017 or early 2018.

“The Shore to Core competition and resulting proposals truly offered insights into how we can plan a strong and vibrant future for our city,” said Jeri Muoio, Mayor of the City of West Palm Beach. “Ecosistema Urbano’s design was applauded by all as enhancing the waterfront and creating new, iconic experiences that incorporate our natural resources, cultural spaces, and inclusive urban atmospheres.”

“Ecosistema Urbano’s proposal addresses social cohesion in a compelling way by integrating locally responsive systems with a welcoming public space that will further diversify the city,” said David van der Leer, Executive Director of Van Alen Institute. “We’re thrilled that West Palm Beach is looking to the future and rethinking how to create a downtown that is uniquely theirs— a downtown that enhances the wellbeing of residents and visitors alike.

The runner-up design finalist, Perkins + Will, created a proposal focusing on community-building with a continuous waterfront park, extended Great Lawn, and the Banyan Garage revitalized as a multi-use civic space. Van Alen has synthesized the work of the finalist teams into a key findings document, “A Shore Thing: Key Findings from the Shore to Core Competition,” that summarizes the shared insights from all three proposals.

The Shore to Core competition has parallel research and design tracks: The aim of this structure is to understand how waterfront cities like West Palm Beach can become healthier, and to create design strategies that will make them more responsive to rising sea levels. The winning research team, Happier by Design, focused on how specific types of public spaces may increase the wellbeing of people who use them, and conducted a pilot study analyzing the health benefits of more complex and engaging urban landscapes.

By testing environmental psychology principals with tactical urban interventions, Happier by Design found that public space designs that boost feelings of fascination foster wellbeing. The research team also recommended that designers focus individuals’ attention on nature and create spaces that are both comfortable and interactive, including such features as movable seating and adjustable lookouts that frame the landscape. The team’s recommendations affirm the dynamic and engaging designs proposed by Ecosistema Urbano. The combination of innovative research and original design in Shore to Core reflects Van Alen’s mission to use research and design to inform the planning of new civic spaces.

Ecosistema Urbano is working with the European Commission in EU GPP Criteria for Public Space Maintenance

Category: ⚐ EN+ecosistema urbano+news+research+sustainability+work in progress

We are glad to announce our recent collaboration with the Joint Research Center of the European Commission in Seville for a research project focused on the topic of maintenance of public space. The project aims to define the EU Green Public Procurement (GPP) Criteria for Public Space Maintenance.

But.. what is exactly EU GPP? Here there is a short description coming directly from the European Commission official webpage.

Green Public Procurement (GPP) is defined in the Communication (COM (2008) 400) “Public procurement for a better environment” as “a process whereby public authorities seek to procure goods, services and works with a reduced environmental impact throughout their life cycle when compared to goods, services and works with the same primary function that would otherwise be procured.”  GPP is a voluntary instrument, which means that Member States and public authorities can determine the extent to which they implement it.

Public authorities are major consumers in Europe: they spend approximately 1.8 trillion euro annually, representing around 14 % of the EU’s gross domestic product. By using their purchasing power to choose goods and services with lower impacts on the environment, they can make an important contribution to sustainable consumption and production.

Green purchasing is also about influencing the market. By promoting and using GPP, public authorities can provide industry with real incentives for developing green technologies and products. In some sectors, public purchasers command a significant share of the market (e.g. public transport and construction, health services and education) and so their decisions have considerable impact. EU GPP is an important tool as it can contribute to the stimulation of the market for environmentally-friendly goods, works and services and to contribute to the development of a more resource-efficient economy in the EU. The Commission has developed EU GPP criteria for around 20 different product groups.

Here the complete list of 20 product groups considered for EU GPP Criteria, and as you may notice the range is really wide, from Office Building Design, Construction and Management, to Transport or Computer and monitors, to mention a few.

We are now working on the first phase of the project for the development of the EU GPP Criteria for Public Space Maintenance. One of the very first document produced is a Stakeholder Questionnaire aiming to define the scope. The questionnaire has been sent to several identified stakeholders from the supply side (Providers of maintenance services, equipment, public furniture, etc), demand side (public and non-public procurers) and other stakeholders, such as national or local policy makers, environmental organizations, urban planners and designers, citizens organizations, etc.

The scoping questionnaire is available at the following link for all interested parties to contribute:

http://susproc.jrc.ec.europa.eu/Public_space_maintenance/documents.html

If you are interested in participating please express your opinion through the questionnaire, and submit it to the email address

JRC-PUBLIC-SPACE-MAINTENANCE@ec.europa.eu before the 17th March 2017.

Further questions or registration by sending an email to JRC-PUBLIC-SPACE-MAINTENANCE@ec.europa.eu

Ruralism: The Future of Villages and Small Towns in an Urbanizing World | Book and Interview

Category: ⚐ EN+publications+sustainability+urbanism

Ruralism: The Future of Villages and Small Towns in an Urbanizing World book

Last year we were contacted by Vanessa Miriam Carlow from the Institute for Sustainable Urbanism to make an interview for the book Ruralism: The Future of Villages and Small Towns in an Urbanizing World. This book is dedicated to the significance of rural spaces ‘as a starting point for transformation’. Different international experts were asked to reflect on rural spaces from an architectural, cultural, gender-oriented, ecological, and political perspective and ask how a (new) vision of the rural can be formulated. As the introduction states:

In an urbanizing world, the city is considered the ultimate model and the measure of all things. The attention of architects and planners has been almost entirely focused on the city for many years, while rural spaces are all too often associated with visions of economic decline, stagnation and resignation. However, rural spaces are transforming almost as radically as cities. Furthermore, rural spaces play a decisive role in the sustainable development of our living environment—inextricably interlinked with the city as a resource or reservoir. The formerly segregated countryside is now traversed by global and regional flows of people, goods, waste, energy, and information, linking it to urban systems and enabling them to function in the first place.

Today we are publishing the interview, answered by Belinda Tato. If you find it interesting, there is much more in the book! We recommend you to get a printed copy here. Here is the full transcript of the interview:

Q: Your office name, ecosistema urbano, brings with it a certain tension that somehow combines unexpected contrasts. How did you come to this name and what do you want to express with it?

A: It took us a while to choose a name or concept that communicated our interests and the complex reality of urban issues we face. We found the idea of ‘ecosystem’ an appealing one, its definition implies a group of interconnected elements formed by the interaction of a community with their environment. This relationship between the natural and the artificial aims for a balance between these two worlds, and reflects the issues we care about when designing architecture and practicing territorial and urban planning.

Q: In your presentation, you said that during your studies the planning approach mainly focused on infrastructure and the physical environment. How would you describe the situation today?

A: I believe there is a clear shift between the object-focused educational approach from the nineties towards a more polyhedral approach and understanding of cities and design that is happening today. There is a growing interest in considering processes and interactions and taking the social, cultural, or economic aspects into account leading to more comprehensive and ambitious proposals to transform reality.

Q: Which approach does your office have today? How would you describe the current role of the architect and planner?

A: That is not an easy question to answer briefly! We recently made an effort to try to summarize our approach and the result is a kind of manifesto in ten points.

Urban. Social. Design. Three words that describe our dedication: the urban context, the social approach, and the design understood as an action, an interaction, and a tool for transformation. Understanding types of behaviour and processes at different levels is crucial.

Creativity is a network. In a globalized world, creativity is the capacity to connect things innovatively and thus we understand that the protagonist of the creative process is not just a team but an open and multi-layered design network.

Community first. Cities are created and maintained by people for people, and urban development only makes sense when the community cares about it. We work to empower the communities to drive the projects that affect them, so social relevance is guaranteed.

Going glocal. Just as cities have residents and visitors, and planning is made at different scales, every urban project is born in a constant movement between the direct experience and specificity of the local context, and the global, shared flow of information and knowledge.

Accepting –and managing– conflict. Participation, like conversation, means letting all the points of view be raised and listened to. Public debate only makes sense if all the stakeholders are involved. Every project affecting the city has to deal with both opposition and support, consensus and contradiction.

Assuming complexity. Encompassing the complexity of the urban environment requires simplifying it. Instead, we prefer to admit its vast character and understand our work as a thin layer –with limited and, at times, unpredictable effects– carefully inserted into that complexity.

Learning by doing. Our experience grows through practice. We know what we can do, and we challenge ourselves to do what we think we should be doing. We solve the unexpected issues as we move, and then we take our lesson from the process and the results.

Planning… and being flexible. Urban development is what happens in the city while others try to plan it. We think ahead, make our dispositions, but we are always ready for reality to change our plans… mostly for the better. Rigidity kills opportunity, participation and urban life.

Embracing transdisciplinarity: We assume that our role as professionals is evolving, disciplinary bonds are loosening, urban projects are complex, and circumstances are continuously changing. This requires open-minded professionals, flexible enough to adapt their roles and skills and to use unusual tools.

Technology as a social tool: Today’s technology enables us to better relate and interact with each other and with the surrounding environment. As the digital-physical divide narrows and the possibilities multiply, it becomes an increasingly significant element in urban social life.

Keeping it open: Open means transparent, accessible, inclusive, collaborative, modifiable, reproducible. Open means more people can be part of it and benefit from it. These are the attributes that define a project made for the common good.

Ruralism: The Future of Villages and Small Towns in an Urbanizing World book

Q: From your presentation, it emerged that the integration of the local conditions—as a climatic and social issue—represent an important focus of your work. How do you rate the relationship between global-local influence in relation to the architectural or urban design?

A: This is a very interesting question, and one we have asked ourselves several times. We have worked mostly abroad during the last years, and over and over we find the same situation where we have to balance the local and the global dimensions of design and planning. Local conditions are always the main terms of reference for our work. They give accuracy and pertinence to our proposals. They not only determine the boundaries we have to respect, the resources we have available, or the particularities we have to take into account, but also the potential for improvement that each particular place has. Local context is a source of invaluable site-specific knowledge, even if that knowledge is not always conscious or apparent, especially to locals. Opening a project to participation is a great way to make local values stand out and locals become self-aware… if you are able to ask the right questions and then read between the lines, of course. But relying solely on local conditions rarely provides the best solutions. You usually find situations that have become stagnant precisely by the lack of confrontation and external feedback. Then you need to confront the local ‘ways,’ often loaded with prejudices or relative narrowness, or with something else. And that is where global influence comes into play: the contrast, the opposition that clears concepts, breaks groupthink and gives a relative measure to local values. Global is the mirror that local can use to become self-conscious. We could speak of bringing knowledge from the global to the local, or even generating local knowledge by confronting it with the global. But it is also creativity that is being created or transferred. The ability to connect, articulate, and interpret different contexts is crucial whenever a new approach is needed and local conditions have proven insufficient to deliver it.

Q: You showed us some practical examples of your current work, which pursues sustainable approaches in terms of water recycling systems for the kindergarten in Madrid or climatic adaptations for the Expo pavilion in Shanghai. What opportunities do you see for the implementation of sustainable planning tools or strategies in larger, urban scale projects?

A: Urban planning and urban design have a great impact on people’s lives, shaping the way we live, move, relate, consume, etc… In addition to this, its impact will be of a long term as it is less ephemeral than architecture. For these reasons, it is important to design integrating with nature, its cycles and processes, taking advantage of the environment and optimizing interventions.

Q: Let us take a closer look at the countryside: in the current city-centered discourse, rural spaces are often dismissed as declining or stagnating. However, rural spaces also play a critical role in sustainable development, as an inextricably linked counterpart, but also as a complement to the growing city, as extraction sites, natural reservoirs for food, fresh water and air, or as leisure spaces. Do we need to formulate a (new) vision of ‘ruralism’? What would be your definition of the future rural? What new concepts for the rural exist in Spain?

A: When talking about ecosystems, it is crucial to understand the interwoven connections between the urban and the rural, and how they relate and affect each other in a critical balance. Although the urban expansion has some environmental consequences, there are also some interesting phenomena happening. As today’s IT keeps us connected and allows us to work remotely, this neoruralism enables us to have a renewed vision of the territory and its possibilities, offering development opportunities in towns that have been abandoned for decades, for instance in Spain. This new trend is transforming these abandoned towns into new activity hubs, creating a new migration flux from cities. It will be possible to measure the socioeconomic impact of this activity in a few years.

Ruralism: The Future of Villages and Small Towns in an Urbanizing World book

Q: The once remote and quiet countryside is now traversed by global and regional flows of people, goods, waste, energy, and information, interrelating it with the larger urban system. Is a new set of criteria for understanding and appreciating the rural required? How would you measure what is rural and what is urban?

A: In a globalized world with an unprecedented ongoing process of urbanization, and under the impact of climate change and global warming, it is becoming more and more difficult to precisely define the limits between the rural and the urban as the urban footprint is somehow atomizing and gobbling the rural. Cities are the combination and result of the simultaneous interaction between nature and artificial technology, and their ecological footprint expansion forces the extraction of natural resources from even further sources, with obvious environmental consequences. At the local scale, it is necessary to point out the close relationship between the way a city relates to its environment, the way it manages its natural resources, and the quality of life it can provide to its inhabitants. This could be summarized as: the more sustainable a city/territory is, the better its inhabitants will live.

Q: What role do villages and smaller towns have in a world in which the majority live in cities? Could you comment on and describe a bit about the situation in Spain or the other countries you have been working in?

A: In cities, innovation and creativity concentrate and emerge naturally. The rural environment also requires people willing to create, to innovate, to connect, etc…. This creative ruralism could lead to the creation of eco-techno-rural environments, which would provide some of the features of the rural combined with specific services of the urban…the perfect setting for innovation to take place!

Q: Which role could the rural play at the frontlines of regional transformation and sustainability? What are the existing and potential connections between urban and rural spaces?

A: The rural could provide a complementary lifestyle for people fleeing from the city to re-connect or re-localize. At the same time, we would need to explore and expand technology’s possibilities, pushing its actual limits, and foreseeing potential new services that could enhance life in the rural by making it more diverse, fulfilling, and even… more global.

Q: And what role can urban design play in preparing rural life and space for the future? Is the rural an arena for ‘urban’ design at all?

A: I think the challenge would be to create the conditions for social life and interaction. We do have the conditions for that activity to happen digitally, but how can we foster social activity in low-density environments? Would it be necessary to create small urban nodes in the rural? These issues are interesting challenges we have to face conceptually and design-wise.

public space for the extreme: evaporation

Evap·o·rate, to pass off in vapor or in minute particles.

All evaporative cooling rely on the energy required for the evaporation of water to absorb heat from the air and lower the temperature. This is due to the very high enthalpy of vaporization of water, the phase transition between the liquid and the gaseous state requires in fact a large amount of energy (which is more properly called enthalpy) that is taken from the air in the form of sensible heat (which is the temperature, something we feel with our skin and determines our comfort) and it is converted into latent heat (which is an energy “hidden” in the vapor component of the air). The result of this adiabatic process is a drop in the temperature of air and an increase in its humidity, therefore it’s clear that this cooling system is particularly effective in dry and hot climate zones where the higher humidity and the lower temperature can be both seen as advantages. Clearly the evaporating process is a key also for some convective cooling processes (that we treated here) but they rely also on the reduced buoyancy of cooler and more humid air to obtain the final effect while evaporative cooling techniques only rely on the evaporation of water.

Although primitive evaporative techniques were used in ancient times (in combination with convective and ventilation devices like windcatchers and qanats in iran) and porous water jars are still used in many hot areas in combination with Mashrabiya other ventilation apertures to naturally cool down the interior of buildings the use of evaporation to cool down outdoor spaces is very recent. Evaporative cooling depends largely on how effective we are able to evaporate water, and a basic physical variable plays a big role in this case: surface-area-to-volume ratio, the more surface area we are able to expose the more energy we are able to exchange.  There are basically  two ways to proceed nowadays to maximize the surface area, evaporative pads and misting. Evaporative pads are generally used in evaporative cooling machines oriented to indoor cooling, these pads are cheap and effective but they are relatively fragile, require continuous maintenance and are most effective in controlled environments where the airflow can be adjusted and controlled, the “wetpads” are made of porous materials that have to be maintained wet while air passes through. The peculiar structure of these materials offers the largest possible surface area to the passing air which is then humidified and pushed into the building or the room. This technique can’t be used for outdoor cooling clearly because of the required control to the ariflow that is necessary.

Misting is instead widely used nowadays to lower temperatures both in buildings and open spaces. The use of water mist to generate passive cooling in closed buildings is strictly related to passive (or mechanical) evaporation towers and therefore to what we have been explaining in the convective technique post in open spaces the use of water jets and mist is instead very efficient (of course depending on specific climate conditions) and cost effective.

Although it is not strictly designed to be a bioclimatic public space, the Miroir d’eau designed by Michel Corajoud in 2006 in Bordeaux is one of the most successful examples of water evaporation usage in public space design. In this case a large square, just in front of the famouse Place de la Bourse, is designed to be a large water mirror where hundreds of water nozzles spray water from the floor either in the form of a fountain or of a mist cloud. In the first case, where tall gushes are produced, water evaporation is limited and the playful atmosphere dominates the large plaza, but when short mist clouds are produced the evaporation rate of the water is greatly increased and a cooling effect is produced, although in Bordeaux climate conditions are quite mild, and hot days are limited to few occasions during summer the square is very popular.

Vaporizing water coming from the floor is a quite common and effective mean to condition large open spaces, the effect that everybody has noticed of a slight refreshment when passing by a fountain in a square or, even more, while staying close to a waterfall is due to the very same thermodynamic principle, the small drops of water that the are created when water breaks while falling to the ground or splashing into more water dramatically increase the surface-area-to-volume ratio favoring a faster evaporation, the nebulized microscopic drops evaporate instantly causing a sudden temperature drop that can be magnified by the wind or other design inventions. In the Sevilla 1992 EXPO this effect was widely used, large fountains and water basins were placed all around the EXPO along all the main paths and squares to increment climatic comfort, in some areas even vertical walls of water were designed to expose the visitors to an even more effective cooling device, but the most common strategy was the use of conventional fountains and mist nozzles integrated in the many green shading roofs.

The design of these spaces has to be developed with special care, the effectiveness of the strategies used in Seville for example varied much depending on the surrounding conditions, evaporative cooling could be very effective if combined with the right design of protective and shading elements, with a correct sun and wind exposure and material use but could be also nullified simply by not considering the wind variation. Even if water vaporization is widely used in many terraces, bars, public venues, etc. because of its low cost, obtaining an effective bioclimatic effect is harder to achieve. Ecosistema Urbano employs evaporative cooling in one of their seminal project, in the Vallecas ecoboulevard, the Ludic and the Media Tree are not equipped with evaporative towers but with water spraying nozzles that are oriented towards the circular public space beneath them.

The main innovation in the use of evaporation in this case is due to the form of the designed public space, because, as we already said, there is not much to innovate about the nozzles technology itself. Actually the most important issue is the control of the water flow and pressure as it has to be correctly regulated depending on the actual dry-bulb and wet-bulb temperature, relative humidity etc. in the case that those variables are considered, evaporation should be instantaneous without any dripping nor condensation. In the case of the Media Tree temperature and humidity sensors regulate the flow and the pressure of the water flowing to the spraying nozzles constantly adapting it to the weather conditions. In this case the design is particularly effective not only because of the cooling technology but mostly because of the shadow provided by the “trees” themselves and the protective design of the ground section that allow the cooled air to linger in the “inhabited” space and not being immediately dispersed.

But misting has a close bound with atmosphere and space, being one of the few atmospheric phenomena that we can directly observe fog and mist have been used also to define spaces, these new approaches, even though not directly related with bioclimatic architecture, open the door for future developments. In one of their most famous, and paradoxically iconic, works Diller+Scofidio designed a “formless, massless, colorless, weightless, odorless, scaleless, featureless, meaningless” that was basically made of mist and nothing else. Their explication for the work was open-ended, blur-building was not only the name they gave to it but also a factual assertion: the definition of it was also blurry. This event contributed to redefine, or to destroy, the meaning of building and the separation between what is a building and what is environment, up to even questioning what is architecture, for the first time the space was not defined by walls or windows or any stable solid material but was only an undefined mutating cloud made of vaporized water.
But this wasn’t in fact the first building that used mist water to blur its edges (although that they are all curiously related to universal expositions, more about expos here), the Pepsi pavilion in Osaka was the result of the fructuous cooperation between engineers and artists within the Experiments in Art and Technology  group and it was constantly covered with a thick layer of fog that partially hid it. In this case the building was still present and firm, a concrete entity with an interior and exterior form and a “conventional” space inside but the fog sculpture, designed by the japanese artist Fujiko Nakaya who spent her life working with fog, contributed to the creation of a memorable innovative pavilion.

At the Seville EXPO in 1992 the so called “bioclimatic sphere” was also one of the main attractions of the whole exhibition and surely one of the most iconic ones. A tubular sphere was placed in the middle of one of the most important boulevards of the exhibition rounded by fountains and water basins as a part of the bioclimatic design of the open space of the exhibition. Although being highly symbolic and recognizable this sphere as reported in the follow-up publications about the Expo was not really contributing to any bioclimatic effect on the square or the boulevard, this depended basically on the fact that the device was placed in an open space and the diffusion of mist was not controlled in any way (a very interesting publication about the follow up of the climate conditioning in the EXPO 92 has been published by the same engineers that contributed to the design of the project and a short extract can be found here).

In 2016 also the famous artist Olafur Eliasson started working with fog and misting, naturally he is not concerned with the bioclimatic function of fog but more about the terms of landscape and vision and interaction between the user and the fog itself. Placed in the Versailles garden, “fog assembly”, is a ring emitting a swirling mist that involves the objects around and changes appearance depending on the site conditions. The user is invited to interact with the installation, crossing it and begin part of the fog it is producing, in this sense, this artwork can be easily assimilated to a public space generating a connection with the theme of this research.
