2.1 Introduction

Access to housing is a problem that has been worsening in Western countries in recent years due to the international economic crisis and the housing bubble. Moreover is a deep problem started long time ago in third world countries and in reality subject to rapid urbanization.

If on the other hand, we share the view of James Stirling in which he describes the house as one of the last stages of our everyday identity, we understand that the impacts of these trends, not only put in crisis a democratic right, but also intimate customs and cultural rights.

We believe that the “Sustainability”, is the opportunity of meeting our three social components (political, market society, civil). If on one hand the public opinion feels with increasing intensity the environmental problems and defines a “moral tone” on the other side markets perceive new business opportunities in a sustainable market not yet developed.

Rather than to contrast an approach for the decrease against the pro-growth we believe in a new social rebalancing based on essential values of sustainability. The complexity involved in this deep transformation implies the need to work in multidisciplinary processes and lays the foundation for the development of a new paradigm.

“By its nature the concept of sustainability, which brings together environmental, economic and social development in a single thing has to be integrated. […]This means that traditional approaches are inadequate and that we must go beyond the boundary that separates them from other disciplines.”(Sergio Porta “Dancing Street”)

From this arguments comes from the name of our prototype and team: (e)co means “equilibrium through cooperation” and attempts to express the importance of the collective labour and of the multidisciplinary working, that we conceive as a new potential paradigm for the architecture profession, in order to develop an Architecture which is careful with the environment and the contemporary priorities.

2.2 (e)co Project

(e)co project started from the initiative of a group of students of the ETSAV UPC University, which detected the opportunity, inside the Solardecathlon Europe 2012 Competition, to continue the research line started during the previous edition and to form an experimental work team. (e)co Team goals are the creation of a social network, around the project, which is able to debate in public the role of the Architecture in the critical contemporary social-economical context through the development of alternative methodologies related to the sustainable project, in order to guarantee an Architecture more connected to its inhabitants.

Autonomously the (e)co team has generated a social dynamic inside the University, involving the students, a didactical program and a large multidisciplinary network of collaborators, which are essential for the prototype successful development.

Our team believes that the house, as society, can imitate the natural processes

which, in contrast with the common beliefs, are based on the mutual support of systems in equilibrium, and not on competitive mechanisms.

We interpret the house as a system that cooperates with the environment Therefore, the main concerns of our research are:

• The housing accessibility and its costs;

• The ecologic impact control during all processes related to the prototype during all the phases of the project;

• The relationship between the house morphological domestic spaces and the new form of living in a more and more dynamic and changing society (highlighting the equilibrium between new elements and traditional ones);

• The housing durability and its ability to resist the transformations which the users and natural agents go through in time;

• The energy balance of the house during its lifetime;

• The social dynamics that can be generated trough an architectural project.

2.3 Prototype Main Strategy

Solardecathlon is our opportunity to apply a new working method and our philosophy to a real project. Real project boundaries (physical or economic ones) as well as policies are not seen as restrictions but as opportunities to define the adequate strategy. We interpreted the context defined by the Solardecathlon 2012, its rules and their interpretation, as a long process fitted with a previous and post competition life, and not as an ephemeral event.

The legislation introduces many physical entities and restrictions:

• A minimum acclimatized area of 45 m2

• A maximum acclimatized area of 70 m2

• A maximum architectural footprint of 150 m2

• A minimum internal space height of 2.20 m

• A solar envelope geometrically described by the figure below

Coherently with a discourse of comfort balance, economic and energy footprint, we are interested in taking advantage of this dichotomy between “acclimatized area” and “not acclimatized area”. Through it we criticize our needs and the energy required to satisfy this needs.

Is it really always necessary for all of our living spaces to meet comfort standards at the same time?

What is the energy involved in order to achieve sustainability?

What do we mean with “comfort”?

And how far it could be accomplished using only physical processes and passive energy?

Figure2.Prototype main strategy

By comparing maximum and minimum, we introduce, in economic terms our intention to occupy the maximum volume allowed without it being all acclimatized. Therefore we are able to offer the same volume with a relevant lower cost.

This extra volume generated by an exterior primary skin, decreases the price per m2 or m3 of the house, also ensuring a necessary comfort areas. The first envelope has to solve some primary problems as water tightness and wind protection. But also we require it some important strategically features:

• Low-cost

• Bioclimatic contribution

• Energy intake

• Atmosphere protection and filtering

• Space and architectural quality

(e)co operates as a “box in box” prototype where each layer has its own features and requirements. The low cost greenhouse envelope defines a hybrid intermediate space and also allows us dissociate these acclimatized zones and to manage them in smaller independent volumes. On the one hand the outer skin has to be a primary optimized element able to cope with external agents. On the other hand the inner skin is protected from the agents, however it has to solve high comfort control and low environmental impact.

2.3 House Design Description

Analyzing the actual economic system where the industrialized processes are in antithesis with local micro economies, our reflection on this subject is materialized as the separation of the prototype in two basic cycles:

• Exterior Industrialized Cycle

• Interior Organic Cycle.

The tension between these components generate a third entities that we call:

• In-between space

The disintegration of domestic space for different grades is also relevant to develop new responses that architecture has to know how to offer in a society where high social nomadism becomes high private nomadism. Contemporary homes have to be able to withstand constant changes of user and to show this flexibility and durability to different uses as its primary virtue.

First skin: industrialized systems- agricultural greenhouses

The first skin (Industrialized, technical Cycle) aims to solve basic environment relation phenomena. In order to occupy the maximum volume allowed with a lower cost, we chose a standard greenhouse system already existing in the market.

The first building skin is acting as a filter. Thanks to its varying enclosure walls, it allows the greenhouse to work as acclimatization machinery. All the façades are covered by cellular polycarbonate prefabricated panels. The opening system is solved by big sliding doors, which allow spatial continuity and the extension of the interspace to the exterior. All the solar capture systems are

integrated in the greenhouse structure.

Second skin: organic materials modules- physical amd spacial features

The second building skin (Organic Cycle) defines the maximum comfort and quality spaces. Its blueprint represents the minimal area allowed by the competition rules regarding acclimatized spaces: 45m2.

Light and opened elements´ disaggregation allows an easier energetic management and different spaces interpretations by different inhabitants of the dwelling.

Apart form all technologic and climatic features as well as plumbing and installation of all kind, the exterior skin allows an organic/natural design of the interior modules, which are able to be biodegradable and recyclable. This way the dichotomy between the two defined cycles is accomplished.

The three modules are conceived as three volumes which are free to the user interpretation. The three modules incorporate records to be used as a bathroom or kitchen.

The structure is built with laminated wood panels. The wooden structure is the internal finish as well. All the doors chosen are all equals to ensure indeterminacy to the three modules. A skylight in each module allows the extension of the vertical gaze to the volume generated by the greenhouse. Doubling the surface of the modules and taking into account the attic surface, we are able to offer at the same price, 163 m2 rather than 128 m2 (128m2 + 35 of useful area of the loft).

In-beetween space, microclimatic space

The joint between inner and outer building skins has a depth and a function. So we may define it as a “limit” and understand it as a relationships and exchanges space. Using this first filter we are able to generate a hybrid basic micro-climatic space. This last defined space is able to offer the inhabitants a passive economical approach towards meeting comfort standards. It also generates an interactive environment between interior and exterior space, public and private space, that we call “intermediate space”.

The intermediate space is the revolutionary element of our project. Through it, we criticize the energy demand of an ordinary dwelling and we define new existential appropriable spaces which do not need to always meet comfort standards.

3. Architecture and users, “resistance to life”

The disintegration of domestic space in different gradients is also relevant to develop new solutions that architecture has to have in a society where high social nomadism becomes high private nomadism. Contemporary dwellings have to be able to withstand constant changes of user and to show this flexibility and durability to different uses as its primary virtue. To achieve this feature that we will call it “resistance to life”, the (e)co prototype offers itself to the users with an high grade of indetermination. It aims to be able to offer a comfortable livable structure that can be appropriated by the potential different users. In order to achieve this purpose we had to stretch the limit between what we thought we had to design as architects and what we don´t have to define, leaving it to be decided by the user. What we believe to really make the architecture alive, from the technical facilities (deigned in a flexible manner without being linked to a specific user) to the modules facades is to promote and simulate the users’ interpretation processes.

eNGINeeRING AND CONSTRUCTION BRIeF RePORT

32.1 Introduction

Energetic and constructive decisions in (e)co has been used not only as a resolvent tools but also a project component from the begining. That is the reason why the aesthetics project answer to functional and constructive criteria.

The constructive and engineering strategy responds to values based on function-ality from the reinterpretation of existent systems. Taking elementary solutions and systems to adapt and transform them according to contemporany needs. In-novate the elementary reinterpreting and evolving each component and system.

This strategy has been carried out through three basic principles.

- Indecisiveness between systems: Our project is based on the indecisiveness between systems to get more user’s flexybility and adaptability in spaces ap-propriation. That is the reason why constructive systems become independents to avoid determination among them, limiting the adaptability or perfectibility ca-pacity.

- Easy construction: We understand that easy construction is a valu in our project not only for the contexts conditions but it also offers easy recognizable systems , so they are modifiable or even self-constructed by users. This attitude has carried us to simplify and clarify constructive and engineering systems to be able to build them without using heavy machinery or technicians on site.

- Maximum simplicity maximum funcionality. Due to the project importance of constructive systems, we have sought that solutions adopted respond to more than one function, looking for maximum simplicity and efficiency of constructve systems.

ELECTRICAL AND HOME AUTOMATION SYSTEM

The layout of the facilities, electrical, home automation and water is formed by a perimeter ring attached to the outer skin.

The indecisiveness between facilities and the interior space of each modul and the distribution of furniture allows the user maximum flexibility to adapt the spaces to the needs of eachone.

The perimeter ring generate flexible and adaptable entry and exit points to allow changes throughout the user’s life. The only element linked to the outer skin are the photovoltaic panels that also favor the behavior of the greenhouse climate increassing air pressures gener-ating artificial ventilation.

energy efficiency brief report 44.1 Introduction The project explores concepts such as solar thermal energy captation and accumulation, energy generation, considering the dwelling as an active object in relation to the user by creating flexible intermediate spaces and varying microclimates 24 hours a day, 365 days per year. It researches highly important aspects such as natural lighting and low consumption systems.

The chosen bioclimatic architecture solutions are based on the use of materials of reasonable cost, tending towards solutions “Low-tech”, betting on innovative and optimized combination of materials rather than solutions “high-tech” that often have the greatest environmental impact.

4.2 Efficiency of the House`s Envelope.

(e)co Project aims to generate maximum comfort level inside the micro climatic space during the entire year in order to achieve a minimal economic cost and energy consumption. It is introduced the concept of “useful temporary area”.

So, our project aims to take benefit from a Low Tech concept. It stores the solar thermal energy and takes advantage of the natural light, low consumption appliances in order to optimize the energy demand.

(e)co’s bioclimatic strategy is based on the continuous study of intermediate spaces and the creation of microclimates. It understand the household as an active purpose in direct relationship with the user by creating adaptable intermediate spaces that vary throughout the seasons and during the day.

A study about different shape solutions has been carried out in which a specific volume has been conditioned and thermally insulated, surrounded by an envelope creating different kinds of spaces.

As it can be observed, thermal conditions in microclimates and their evolution are directly related to the decisions made regarding the shape of the volume. It is interesting to understand these spaces as additional areas that can be used at different times of the day and the seasons.

(e)co takes advantage of these intermediate spaces to provide the user with an additional useful surface. This space is not conditioned, and its comfort depends on the correct use of climatic conditions. It has to be understood that this space will be different depending on the time of the day and the season; therefore the household, regarding its spaces, varies during the day and the season.

4.3 Efficiency of passive or mostly passive

Echo uses different passive systems to adapt to environmental changes. The systems are:

* Greenhouse effect

The outer skin of polycarbonate addition to being the first barrier against water and wind produces the phenomenon of “greenhouse effect” benefiting themaximum solar radiation.

Gross area: 150 m2

Gross Volume: 557.32 m3

Surface area: 328.46 m2

Net floor area: 45.45 m2

Conditioned Volume: 104.5 m3

JURY REPORTS


• Ventilation

Natural ventilation supply and remove air through an indoor space by natural means. There are two types of natural ventilation occurring in buildings: wind driven ventilation and stack ventilation. The pressures generated by buoyancy, also known as ‘the stack effect’, are quite low (typical values: 0.3 Pa to 3 Pa) while wind pressures are usually far greater (~1 Pa to 35 Pa). The majority of buildings employing natural ventilation rely primarily on wind driven ventilation, but stack ventilation has several benefits. The most efficient design for a natural ventilation building should implement both types of ventilation.

• Insulation and shadow

A proper balance between insulation and ventilation is essential to maintain adequate indoor thermal conditions. The dynamic simulation tool helped us to define architectural and occultation strategies in order to control direct solar gain transmitted to the interior of the house.

“During the cold winter days the outer skin remove its sun protections, it is closed and uses its translucency to act like a greenhouse. In this way, leaves to enter a big part of the solar radiation into its interior and so, the interior materials are heated up to emit heat in infrared. “

“During the hot summer days, our greenhouse is covered with an interior sunscreen, avoiding direct solar radiation and therefore the overheating of our intermediate space. The filters generate interstitial spaces between the layers (shading mesh and polycarbonate) making a difference in temperatures that will help heat circulation and therefore a natural ventilation.”

“Natural ventilation allow that overheating effect is not occur on the “in-between” due the greenhouse effect. Ventilation is produced from the facade elements to the “photovoltaic roof top hatches” and is favored by the suction effect resulting from the air chamber between the roof and shade screen, hot air under the photovoltaic panels and the venturi effect produced on “photovoltaic roof top hatche”

The direct relationship with the outside echo makes the radiation on the inner surfaces changes considerably, both spatially and temporally. Sunscreens are mainly mobile allowing the house changes throughout the day. For example, in summer, solar radiation is welcome in the early hours of the morning as it has to be avoided as the day progresses.

• Vegetation adiabatic strategy.

(e)co has an innovative air humidification system. This system humidified air through the plant stratum. Each gram of water evaporated by vegetation absorbs 540 calories of the air. In addition, the vegetation serves as a natural filter of the air pollutants, fixing the carbon dioxide and releasing oxygen. When we enter an area with abundant vegetation, we note that “its cooler”, because the plants retain moisture and cool the environment. oInertia.

4.4 Efficiency of semi-active system

Thermal mass and mechanical ventilation system

As we have a building that has no mass or inertia we pretend to put our house in order with a system that does not work independently but with a complementary functioning, instead it is integrated in global strategy of the project. Our climatic support strategy is based on capturing and accumulation energy.

In order for the greenhouse-shaded house system to be fully efficient, it is necessary to include an energy-storage system, a buffer tank. The greenhouse-shaded house conditions both the intermediate and the indoors spaces at those times when energy demands are low; the buffer tank helps condition the house when the demands are maximum.

Our system uses the gravel as a heat source (in the winter) or a heat sink (in the summer). This design takes advantage of the moderate temperatures in the objects with high mass due to the inertia or capability to store heat, in order to boost efficiency and reduce the operational costs of heating and cooling systems, and may be combined with solar heating to form a geosolar system with even greater efficiency in order to establish consistent regulation according to external conditions, it is necessary to develop different strategies depending on the period of time of year. For each system, we distinguish winter running and summer running.

the mechanical ventilation of the house is taking the air from btween space (the space is sufficient air changes an hour to consider appropriate). Being a pre-heated air in a better position than the outside air, the impact of air over the temperature of the modules is less than if we take it outside.

The low demand allows the home to operate completely passive systems, or what would be called “free cooling” and “free heating”.

Taking into account both the modules and the gap we should take into account the hours that are within the margins of thermal comfort. The following chart s hows the hours in which at least one of the spaces of the house is within these margins in times of heat.

1.1 Abstract

For (e)co, one of the main priorities in our project is able to influence emphatically our audience independently of their countries, in addition to being able to create broad awareness and knowledge regarding sustainability, innovation and energy efficiency.

The iniquitous insights regarding global warming encourage us since LOW3 project in 2010 to make a change in our society through cooperation, from low to high scale, trying to get an optimistic awareness where a global change is possible and viable indeed.

Therefore, team visual identity within creative dynamics are adressed in order to achieve these goals. (e)+co together involves the existing social context. (e) “green-at” re-interprets the symbol of our time (@). It represents the equilibrium among systems as well as spiral self-generative. -Co means putting together, to include new research, development and diffusion areas, all based on cooperation.

As a result, (e)co is an alternative way of joining technology, resources and users in order to achieve a sustainable progress focused on the development of architecture. The balance between the vibrant light green that symbolizes modern balance and “co” in black reminder of co2 as well as cooperation give vitality and notoriety to the”brand”

1.2 Communication plan: cooperation

One of the main goals for the team is to nurture cooperation for a new sustainable lifestyle. Therefore, subgoals are stablished in order to achieve them, making audience aware of the possibility of a mind-change through activitives and actions, like a “guerrilla” marketing campaign. It is clear that we must determinate to whom the project messages are addressed. It also gives us guidelines to focus on our main objectives as well to indentify which dynamics and platforms should be used.

The team considered organising seven target groups regarding its ethnology, demography and geography in addition to beginning locally to global scale.

JURY REPORTS


The team pretend to transform inhabitants of the cities to users of the change we propose, promoting social awareness and knowledge regarding sustainability, innovations and energy efficiency. Through actions and activitys campaign in which low-cost creative means are utilized, the team aims to achieve different goals in a competitive and sometimes unforgiving environment. The team made a calendar where illustrates the different relationships between present and future (e)co activities including its timeline and the seven target audience groups, making activies from childreen to non-green consumers.

The importance of becoming an immediate behavior invites in a friendly way to become participant of cooperation. And we did it through open public journeys, conferences, lessons, congresses, discuccions, workshops, creating subjects from local university, social activities, child and non-green activities, TV and radio appearances and media coverage through media platforms. This way the project turns in fact, into cooperation.

Audience reached from actions

Throughout past two years, the team made around 35 open activities distributed in 18 locals, 11 national and 6 international. As a “guerrilla” marketing campaign in which low cost is one of the main strategies, the team dedicated just 3475 €, including all trips and logystics, .

People involved - nearly about 3515 people.

MEDIA campaign

Beginning from local to national scale, (e)co team established arrangements among media press which included magazines and newspapers interested in subjects as energy sustainability, ecology and architecture.

Furthermore, the communication plan uses other communication channels in order to broadcast our key messages, attaining placement in Media.

Tracking table:

12 articles in newspapers64 articles published in webs and blogs7 TV appearances5 Radio interviews

Thanks to the department of communication of Universitat Politécnica de Catalunya who give us periodically reports of the audience reached just in newspapers, we can show these statistics of the total 12 articles in newspaper:

2.571.800 readers on average1.214,5 cm² of area published9.201 € value

Communication plan: viral campaign

(e)co is also a platform to broadcast our key messages transmitting dissemination of a life model based on cooperation, a model for all scales, for all users, a model which will re-establish the dialog between people and resources (natural / economic), the true meaning of ecology.

There exist several platforms in order to transmit the project through the localized target audience, creating large broadcast and social awareness.

JURY REPORTS


Awareness campaign to issue our messages is also supported by large media campaign throughout different communication platforms. We actually work with our Webpage, Twitter, Issuu, Facebook page, Blog, Flickr, Wordpress, Vimeo and Youtube Channel. Just as an example, our Facebook page is increasing day by day, currently getting more than 395.150 post views from March of 2011 and more than 1865 followers.

We recently started a publication in our blog where the team writes summaries of the other participating teams. Our blog has more tha 11945 visits.

Innovation

To attain audience and support of non-interested target groups, as we described as nongreen and young audience, became an important novelty as well as an opportunity to carry out by the team. Many activities are focused to create eco-friendly awareness among target groups, organizations and public institutions. Artists, general public and professionals work together on distributing information, generating participation and creating commitment through the (e)community with go(e)co!

Online and offline activities have been organized to attract the attention of non just the general public but other interested audience as well as non-green minds.

Fresh media platforms such as Youtube channel, (e)co page in Facebook, Twitter and blogs, allow the team get more audience in addition to participation and green social awareness.

Some of the most innovative ways to interact with the (e)co project are through web and smartphones as well as generating active participation in our social networks:

• Augmented reality• Interactive virtual tour• Social networks competitions

6.1 INDUSTRALIZATION DEGREE

(e)co is based on open industrialization. It involves using resources already existent in the context market. (e)co’s design coordinates the standard dimensions of components taking into account transport limitations. Innovation is present in the way components are implemented and cooperate within the whole prototype and its environment.

Seeking the reduction of both energy and material wastes due to production, transport, assembling, use and disassembling processes (e)co approaches the closed life cycle concept.

Indeterminacy is (e)co’s key feature. It provides highly flexible spaces adaptable to different uses and simplifies the industrialized production. All modules are equally equipped and climatically independent. This way, instead of a distinct spaces for each activity (e)co provides a neutral game board where users interact actively in the space construction.

Modules can be placed anywhere within the in between space. A change on module’s relative position entails to a completely different space.

(e)co can grow and mutate in time according to user’s needs. It can be expanded by adding trusses as well as completely dismantled to be rebuilt somewhere else.

In height, the standard greenhouse structure stands up to three levels (9m). Optimum climatic comfort is achieved at this high. The interior modules can be dimensioned to stand several levels on top of each other.

(e)co is transported in two lorries: an ordinary one and a special transport.

Combining two opposed strategies -extreme prefabrication for the modules and on-site industrialized assembling system for the external envelope, (e)co achieves an optimal equilibrium between transport an assembly costs and times and releases living space from transport dimensional limitations.

To reduce costs and time, the assembly process pursuit two objectives: the radical reduction of machinery and tools subordination and the organization of the assembly process in several simultaneous tasks.

6.2 MARKET VIABILITY OF THE PRODUCT

The analysis of the viability of (e)co is centered in Spanish teritory as following the vision of thinking globally and acting locally, we believe that (e)co has the responsability of offering solutions to endemic social issues.

Analysis of the relevant market (ecologic prefabricated buildings)

1. Spanish prefabricated building market is less developed than the European. Advantage: less competitors in the market. Risk: European more experienced firms becoming competitors in the relevant market.

2. Sustainability is a value for all competitors. Risk: declared features do not allways correspond to reallity confusing consumers.

3. Most of the competitors offer modules or assembly systems. (e)co industrialization strategy consists in combining both in order to avoid limitations due to transport and to achieve fast and easy assembly.

4. The majority of firms offers finished products. In contrast, (e)co offers a set of strategies, highly flexible to adapt to specific demands. (e)co also offers KNOW-HOW service and support for autocontruction or customization.

5. The target market of most firms is the end user. (e)co bets for reaching more markets by addressing also constructors and institutions.

6. Sustainability, comfort and architectural quality are “extras”. (e)co aims to make this extra features afordable for a larger target market by:

high level of quality design without the necessity of high-tech products

open industrialization

offering (e)co as a service that can be rented for a limited period of time

perfectability

the possibility to choose the level of prefabrication of each part of (e)co

7. The major part of the competitors is specialized on single family dwellings. Due to its hight flexibility, (e)co is able to accomodate more functions.

8. All of the competitors focuses on new building work. Some suggest the possibility to extend existing dwellings but (e)co explores the possibility of refurbishment and reuse of buildings followings.

Strategic improvement of existing constructions

Reuse of existing buildings

New construction

The main features of (e)co marketing:

• Affordability - High quality at a low cost

• Self-sufficiency - Suitable for places with no facility supplies

• Low Manteninece - Now & here technology makes (e)co elements easily replaceable

• Highly flexible - Perfectable, adaptable to changing demands

• Reversable -

• Adaptability

• Architectural quality

The Spanish context can be described through three main singularities:

• A shift to sustainability

• The burst of the housing bubble

• Reduced access to housing

sustainability brief report77.1 Introduction

(e)co project deals with sustainability from a holistic point of view, approaching the current discussion about what is understood by sustainability: what criteria define it and how representative it is.

Regarding the prototype, (e)co´s aim is to close the life cycle of all elements. As elements, (e)co consider and treats with the same importance matter, water and energy.

Regarding energy, the basic objective is to produce more energy than it is consumed. This is the first thing done is to reduce energy demand. This is noticeable in the energy demand being of 2,880 kWh for heating and 2,926 kWh for cooling. This represents a savings of 75% and 2% respectively compared to standard housing.

As in the case of water, to close energy’s cycle, the first objective is to lower the demand. The following step is the production of energy by the prototype’s own means, i.e. to obtain a self-sufficient in energy prototype with the less consumption possible.

(e)co’s goal is to close the water cycle. On this purpose (e)co achieves to reduce fresh water consume to 40% of the total consume, it means 58 litres per person per day.

Regarding to construction materials, tha mass of (e)co is 164Kg/ m², while the average in Catalonia is 2793Kg/m². Energy production sum 2500MJ/m2 whereas the average in catalonia is 9070Mj/ m² and its associated emissions are 313,79kgCO2/ m², while in Catalonia are 732,5KgCo2/ m². (e)co dicreases 94% the weight per surface, 72% consuptiom of energy production and 50% of emissions with regard to the average in Catalonia.

El planeta tierra y sus recursos son finitos, la sostenibilidad consiste en no comprometer los recursos de las generaciones futuras por lo que la estrategia pasa por conseguir trabajar con ciclos de vida cerrados.

CICLO MATERIAL

Hoy en dia la vida de un recurso suele empezar por su extracción de la naturaleza, su posterior consumo y su muerte en forma de residuo. Los ciclos cerrados pretenden eliminar los residuos a través de la reutilización, el reciclaje o el retorno a la naturaleza.

En el prototipo podemos distinguir dos tipos de materia, los materiales de construcción que dan forma al prototipo y los residuos generados tanto por su construcción, como por su uso y posterior deconstrucción.

Como materia, (e)co tiene una energía medible y unas emisiones de gases de efecto invernadero asociadas.

Nuestro objetivo es disminuir la cantidad de materia y su energía asociada, mediante una adecuada elección y optimización de los materiales y una correcta gestión de los residuos.

Para ello tenemos en cuenta el ciclo de vida de los materiales, desde la extracción de las materias primas hasta el fin de su vida útil.

Para reducir el consumo no nos conformamos con un cambio de hábitos por parte del usuario, (e)co trata las aguas grises y el agua pluvial mediante procesos de remediación y filtraje natural para conseguir una calidad de agua que permita utilizarla para determinados usos domésticos.

Una vez regeneradas las aguas grises que provienen de la lavadora, el lavabo, el lavavajillas o la ducha, se pueden reutilizar para algunos usos domésticos. El agua regenerada no utilizada se devuelve al medio a modo de recurso hídrico o bien se comparte con otros usuarios. El objetivo final es siempre cerrar el cilco del agua.

7.2 Energy Cycle - Bioclimatic Strategies

The bioclimatic strategy is determined by the global vision of the sustainability concept that the project promotes. We understand that one of the requisites of the project is reducing the energy demand and debating the comfort standards. (e)co’s design is conceived from its origin in response to the climate conditions, seeking to fully adapt to the surrounding environment. This reflects on how the climatic conditions (orientation, temperature, humidity, etc…) are taking into consideration in the house, intelligently responding to:

• House envelope, taking into account the level of insulation, air tightness, finishes and construction.

The design of the prototype is clearly linked to the bioclimatic strategy as we are talking about an element with an agricultural greenhouse structure and a part of its skin working as captor. This captor allows passing only the sun’s radiation light wave and does not let it leave once it comes to an infrared wave length because of the colliding with the interior elements. This is what is usually called the greenhouse effect. Another part of the skin is formed by materials that prevent solar radiation.

To produce the greenhouse effect at a satisfactory manner it is necessary for the prototype to ensure the air tightness. For this reason the outer skin acts like a boundary membrane between the inside and the outside, minimizing the infiltrations. The materials used will respond to the bioclimatic strategy. The outer envelope will allow to capture solar radiation in those places where its necessary. The inner envelope will help in reaching a thermal balance by controlling heat gains and losses. Besides, this envelope will be in charge of building up energy in order to free it later, diminishing thermal variations as much as possible.

• Glazing orientations, types and sizes. Solar protections to minimize the interior overheating. Daylight controls to provide evenly distributed and sufficient natural lighting.

The south facade acts as captor one, while the north is used for ventilation. The type and size of the holes is dimensioned to facilitate the ventilation of the house. The ventilation holes are concentrated in the north facade directing the wind to pass from a moist chamber, which results in the reduction of the air temperature. At the same time, there is a shadow mesh to avoid heating.

• Distribution of the interior spaces according their heating and cooling requirements, and the use of thermal buffers spaces.

The architectural design of the prototype and its spatial distribution are determined by the use of an intermediate space as a bioclimatic strategy. The climate control of this intermediate space is being realized in a passive manner, using the same building as a climate machine. This space, although it is not considered like an air-conditioned space in the competition, will be in a position of comfort during the 60% of the year. Furthermore, this space function is to serve as a climate cushion between the external and the space considered habitable and air-conditioned.

• Use of semi-passive systems to maximizes the effect of passive strategies with very low energy consumption.

As part of the prototype’s energy strategy to dissipate heat in summer and provide warmth in winter, auxiliary elements like a buffer tank of gravels are used. This tank produces inertia accumulating heat when an excess of heat is observed and then provided when its needed.

7.4 Material Cycle

Regarding matter, the model that prevails today is linear and based on “take-make-waste” model. (e)co considers essential to change this model and aims to make a cyclical one base on “borrow-use-return” sustainable model. We consider it an issue where the industry has a great role which is still anchored in the linear model.

First of all, our strategy is to reduce material usage. Thanks to the design stage optimization of the materials and to the careful selection of them, we have reduced by 92% the amount of water per m2 with respect to the average water consumption in Catalan buildings.

In order to achieve that, construction materials selection is taking into account that the materials used have to be able to be reincorporated into the industrial cycle or directly to the environment. They also have to be low embodied energy materials. Compared to the average building in Catalonia, (e)co is able to reduce 57% of the embodied energy per m2, and 43.8% of the greenhouse gases per m2.

In the cyclical model (e)co aims to eliminate waste. In order to achieve this, we used systems that allow a quick disassembly and thus facilitate the reuse and recycling, only 2.4% of the total mass ends up in the landfill, the rest is reused directly or recycled to make new components. The prototype’s furniture is a clear example of the philosophy “waste = food”. We have used elements considered waste by society and which we believe they are still useful for the same or for different function. Another example is the use of waste material from wood industry to manufacture the facilities cabinets.

When talking about waste, we miss the waste generated during the lifetime of the building and which can become 50 times greater than construction waste.

The first strategic action is to reduce the amount of material needed and which unfortunately convert into waste.

In the case of the organic materials, closing the cycle is transforming it in compost for the garden. That is why user’s habits are very important in this process; (e)co is only providing the facilities for an easy management.

7.3 Water Cycle

In (e)co prototype the water cycle is closed reducing the consume of drinking water to the maximum. A reduction of 60% can be achieved by our strategy. The solution proposed is technically as well as economically plausible. Moreover, it strongly supports sustainability in the use of natural technologies and closing the water cycle.

The strategy consists of recovering rain water and greywater, and treating them to get two qualities of water. Both qualities meet as minimum the health standards for bathing water. Therefore, both water types can be used inside the dwelling for several applications that do not involve drinking. For example: irrigation, washing machine, dishwasher, even hand washing and shower.

(e)co’s water treatment is a standard potabilisation process of depuration and disinfection.

The rainwater treatment consists of a first phase of elimination of solids through a sieve, followed by disinfection with chlorine tablets.

The grey water is recycled by removing suspended solids by decantation, followed by a secondary treatment which removes organic matter and nutrients through an artificial wetland, which is a totally natural process. The third treatment is a disinfection.

All treated water is continuously being recirculated, so that it does not standstill in the tank. The pH and the amount of chlorine needed to maintain a concentration of 1ppm of residual chlorine is automatically controlled. It could also be stored for several days.

In order that the responsibility to where using the different qualities of water rests on the user, (e)co provides for the dwelling 3 types of water: drinking water (hot and cold), rainwater and recycled gray water. This is achieved by a perimeter ring, surrounding the house, from which each type of water has an independent system.

This is the innovative part proposed by (e)co, a system that does not respond to a standard but it serves any need that arises. (e)co anticipates the current regulations based on the supply of only drinking water quality inside the house, and makes the user responsible for the proper use of the water cycle, from treatment to the final stage.

By using the proper quality of water for each type of use allows us to save drinking water (from 144l/p.d to <58l/p.d) and therefore all the energy that is associated to its treatment.

(e)co achieves a sustainable water cycle that can be easily implemented by users willing to adapt their lifestyle to a new social demand based on sustainability.
