IntroductionThe EBSKA House is characterized by his modular structure, pre fabrication and efciency energy. It is a rigorous and simultaneously exible building in his composition due to the work of reection invested on prefabricated modules that can be formed and incorpora-ted by users request.

The building remains formed by a modular composition where every user can choose the number of modules of the housing or ofce, depending on the necessary spaces and the use that the client wants to give (familiar, second housing, work, etc.).The project is based on a set of modules that allow to mount and to dismantle easily the house in such a way that choosing different The project is based on a set of modules that allow to mount and to dismantle easily the house in such a way that choosing different modules, by request of the user, different models of housings might be formed, taking advantage of every space, combining day and night spaces with work spaces. The rst variable that determines the conguration of the housing is the number of users.

TheThe order establishes in this case the dimensional limit of 175 m², for what the reection on the house and ofces to be projected pe-netrates into the possible congurations on 6 modules prefabricated by oor. The organization of these 6 modules was established concerning two longitudinal courts obtained by the exibility of the position of this court contemplated in each module.

In addition, the project also is characterized by 2 longitudinal bands that shelter different functions, from storage up to habitable spaces, where the user decides what use to give it.

TheseThese buildings are very adaptable, so much for the use to give it, as for the number of individuals that are going to use it. With this system of modules there can be created innities of types of houses, adding the above mentioned modules there is provided a linear growth of the housing or ofces. On the other hand the disposition of the spaces has a great exibility, every space possesses a proper entity according to the needs of the owner. All the stays are projec-tedted without residual spaces that cannot be in used by no means as like it happens in some traditional housings. M1M2M3

ARCHITECTURE

ConceptTheThe solar house energetically self-sufcient EBSKA House, has much more than an energetic independence as aim. Based on an exhaustive analysis of life cycle of the materials and components, an optimization of the process of construction, and an adaptable concept to changes of uses, extension, technological update, reutili-zation and recycling, in a future there will be created a new concept of sustainable housing.The realized concept will allow the translation of its principles to a new urban con-formation, betting clearly for a rational use of the territory in the development of our cities.A bioclimatic concept of low energetic consumption joins a low environmental impact of the building during its life cycle, with constructive and technological so-lutions of low cost.

CourtsBothBoth courts of the EBSKA House allows the connection of the interior spaces, segregating three basic stays of a housing and ofces, for the good functioning of the building in bioclimatic terms. Lounge/dining room, kitchen and bedroom as well as ofces, are articulated between them, with the possibility of crossed ventilations and zenithal light income. As these courts are in touch with the façade, on one hand they are the access and on the other hand they break the volumetric forcefulness of the buil-ding.ding.

The courts separate the stays in the daytime and in the nighttime, as also the dry zones with the humid ones. Across them we can accede to the housing or ofce, both for the principal access and for the secondary one.

MaterialsThe use of relatively recent materials has allowed us to overlap façade and interior with photovoltaic integrated panels. The advantage of the manipula-tion of the "Corian" allows, in this case, to t the support and the photovoltaic panel without mortgaging the image of the façade. It opens for a new world of possibilities on the texture to be generated. It permits that the proposed architecture is not the direct result of the existing technology.

In our case the objective was to recognize fragmented elements in horizontal lines every 20 cm (requirements of manufacture and installation) and a clear intention of simulating a at line architecture.

RoofLThe roof arises from the combination of hybrid systems of thermal solar and pho-tovoltaic capture overlapped in the same technological plane, allowing an ideal pro-portion between both systems in every moment.

A metallic frame is dressed as the rest of the building with photovoltaic panels and in the interior we have the thermal panels. In spite of the inclination proposed for the creation of the waterfall, all the roof is arranged with the intention of remaining this constant horizontal plane that nishes off the building.

ENGINEERING AND CONSTRUCTION

Constructive designThe structure is independent in each module. It tries to be as light as possible and at the same time it’s integrated in the constructive conception of the architecture modu-les.The courts are generated with the incorporation of 4 proles UPN 200, like a ring, which each location changes according to the position of the court to obtain the diffe-rent possibilities of the modules.

The orientation of beams and pillars allows to easily solve the meeting between modu-les. The support of the building in the land is based on 6 points for each module, in which they support 3 proles HEB 200 that will distribute the charges of the module uniformly. Every point of support is formed with a tubular substructure of steel, easily assembly, which rests on 4 points plate of steel (100x100x0,6 cm), which will distribu-te to the area the charges uniformly.The whole building has been suitably isolated so that there is minimized the number of thermal bridges along the building. Due to the great quantity of semitransparent surfa-ce that has the building, a correct design of windows has become necessary, since they allow to contribute to many light, they also imply a considerable reduction of the thermal isolation.

Electricity and plumbingThe facilities of electricity and plumbing have been designed respecting the concept of modulation that crosses all the aspects of the building. For that we put several connec-tions between modules so that in future extensions it does not modies the already realized installation. Likewise, the connection systems have been unied to allow that 2 different modules should be electrically compatible.On the other hand the plumbing installation has been designed in order that the unions are easily connectable. All this effort has allowed to guarantee the versatility that the building needs to permit the modulation.

IluminationThe last technology in lighting consists of LED utilization for his high efciency. This way, we bet for the forefront technology, so that all the points of light have been placed by the above mentioned technology. LED systems have been adap-ted to the EBSKA House, to respect the design of the concept.

Home AutomationThe home automation installed in the project EBSKA House claims three basic items, integration with the architectural concept, use of the most new technolo-gies and integration with the Industrial systems used for the energy capture.The principal concept is the use of wireless technology, particularly the Z-Wave technology. Nevertheless, due to the youth of this technology there are not enough commercial devices that cover all the needs. So we mix both use of wi-reless technology and standard wired up installations. The fusion of home auto-mated technologies with industrial ones establishes a home automated Ether-net network that it allows to control the whole housing from a PC or the home automated control panel.The remote access to the building will be realized by a Flash application from the web page.

VentilationTheThe correct opening of doors and windows, depending on the wind direction, allows to take advantage of the exterior air to generate currents that ventilate the building. Nevertheless, in case of bad climatic conditions that do not allow the natural ventilation (low wind or high temperature), the building has a venti-lation installation that allows to guarantee a controlled renovation of the air. To avoid big thermal losses in the forced ventilation, the installation has an Inter-changer that allows to recover the heat emitted to the atmosphere.

SUSTAINABILITY

PrincipiesIn the EBSKA House the sustainability is based in ve fundamental aspects; the utilization of the solar power, the reduction of the energetic demand, the increase of the efciency energy of the facilities, the use of innocuous, reusable and amortizable materials and the optimization of water resources (withdrawal + storage, recycling + reutilization).InIn addition the maximum comfort is obtained in the building with the utilization of bioclimatic passive systems (natural lighting and crossed ventila-tions).

9

Bioclimatic strategiesWithWith the utilization of passive systems we tried to obtain the maximum comfort in the building. The introduction of courts for capting natural light, depending on the epoch, reduces the consumption of articial lighting in 20 %. Interior spaces can be opened to generate crossed ventilations in summer that means a reduction of 5 % in air condi-tioning consumption. The courts use makes a double comfort, on one hand the spatial and on the other the climatological.

We employed the drafty façade as a solution for the exterior closing, mufing this way the radiation that affects the building and reducing the consumption in heating and air conditioning in 5 %. In the exterior face of the interior sheet of the front panel, there is a sheet that reects 80 % of infrared emission, so that the quantity of radiation is pre-vented from achieve the insulating system, allowing to reduce enormously the heat load to offsetting. The lines of closets act like thermal additional mattress and installa-tion areas.

WaterThe roof works as a cistern capable of catching the rain water and melting the snow to store it and re-use it later. The building incorporates a system of gray waters recy-cling. There is a possibility to purify black waters for gardening. With the combination of these 3 systems: storage, purication and recycling we obtain an optimal congu-ration adapted to every climatological environment. Devices for water saving are im-plemented.

Materials and residuesTheThe criteria to use sustainable materials are: abundant and renewable sources at origin, materials that consume less energy in the production and have a long useful life. During the construction of the building they produce a minimal quan-tity of waste, since globally they are re-used in the production of the furniture. Those not usable residues are separated, stored and eliminated in clean points of recycling. Finally in the building there is a system of differentiation and sepa-ration of residues.

InnovationTheThe great innovation of the EBSKA House is the implementation of active sys-tems of high efciency of industrial application adapted to the residential sector giving place to the SHS (System of Solar Hybridization) that combines the ther-mal solar power with the photovoltaic one. The thermal collectors of high ef-ciency developed by SRB allow to feed a system of " solar cold " capable of ac-climatize the building across a cold ceiling and a system of ventilation control energetically recycled. This is completed with a system of photovoltaic plates in façade and a photovoltaic retractable system in the roof that retracts when it is not necessary to generate more heat energy, so that the solar capture is optimi-zed to the maximum.

The developed System SHS together with the passive systems allows a saving in the energy consumption of 80 %. The 20 % remaining is achieved by the use of photovoltaic plates that generates more energy of the one that consumes the building, sending the remaining energy to the public network.

EquipmentForced ventilations guarantee the quality of the air inside the building and an inter-changer recovers part of the energy of the generated interior air.In view of the strategic use of the thermal panels of the EBSKA House, we develop a system of warm water supply to electric appliances. In concrete the washer and the dishwasher have this supply system that increases the energy efciency of these domestic appliances on having reduced the need of water warming with other methods.

SOLAR SYSTEMS

Energy BlockOneOne of our prototype aim has been passing the maximum consumption charges of our building to the thermal environment. In this point we assume the value of capture techno-logy with the collectors SRB of ultra empty high place, indicated specially for these inten-tions. Nevertheless this does not supposes a complete use of the solar surface between the photovoltaic power and the photo thermal energy, since both technologies compete for the solar radiation.

The energetic management is a key point in the EBSKA House, since the modules E-Block SHS allow a real time conguration so that they catch thermal or electrical solar power according to the needs of the building. This way we have a powerful system of control that determines the ideal conguration in every moment of the day, taking as references the current and foreseen consumption, the solar radiation and the energetic priorities.

To solve this conict we have implemented a hybrid system of capture inside our Energy Block. On the roof we have three different types of these systems:•• Energy Block-SHS: hybrid photovoltaic and photo thermal blocks capture adaptable on our roof.• Energy Block-T: purely thermal blocks with concentrating mirrors.• Energy Block-PV: purely photovoltaic blocks.

As for the viability study, the creation of these blocks, opens the door for different congu-rations allowing to select one type of capture for each roof. This blocks system would allow to create new blocks to shelter modules also with a certain angle of inclination.

Energy Block SHS Energy Block T Energy Block PV

Photovoltaic energy

The design of our photovoltaic system has followed the following premises:• To put in agreement the criteria for maximizing capture surface with the coexistence of photo thermal surface.• To minimize the charges that our building offers to the electrical consumption.• To maintain the architectural integrity of the project.

The conjunction of these premises will allow us to assume or even to exceed, the criteria of " zero energy building ". By this way we have raised three subsystems of photovoltaic capture:

• Photovoltaic capture in façade: with thin cap modules, since from the energetic point of view they are more ef cient for the diffuse radiation. cient for the diffuse radiation.• Fixed roof: due to the distribution in roof we expose them to a better direct incidence, for this motive we chose mono crystalline cilice modules.• Hybrid roof: The exible element of the solar capture, constituted by the Energy Block-SHS. They catch thermal or electrical solar power according to the needs.

Thermal solar energy

From the thermal point of view our prototype raises an as exact as possible annual demand. We have considered maximizing our thermal cover for winter.

The SRB solar collectors of ultra empty high place manage to extract the maximum advanta-ge of the radiation, even for diffuse radiation. In conviction with the passive strategies we manage to avoid the use of the air conditioning in winter.This maximized roof perfectly ts with the thermal requirements of the proposed absorption system. In the moments in which it is not necessary to generate more heat energy, the system of photovoltaic mobile plates will spread out to optimize the solar capture to the maximum.

12


The chosen absorption system is very demanding with the tempera-ture of load supplied by the capture eld. The election of the collec-tors of ultra empty high place allows us to approach these high tem-peratures with guarantees. We remember that these collectors have been designed as medium temperature solar thermal systems, achieving temperatures of stagnation of 300 Celsius.

We have assumed the challenge of connecting these industrial range systems in the domestic building area, allowing having applications that with conventional systems were not appearing to be tuned in. At the same time this high temperature of stagnation helps us to provi-de the correct coverage in winter.

Thermal OvenOne of the EBSKA House innovations consists on an oven design based on medium temperature thermal co-llectors. These collectors allow taking advantage in a more effective and efcient way of the solar power as heat source, which is led to the oven by hydraulic oil isolated circuits.

Moved by the objective to minimize the electrical charges, and helped by the characteristics of our solar thermal collectors we developed the creation of an oven fed by a solar thermal system.

This installation is independent from the previous one, is more demanding in temperature range. To have 240 Celsius range of temperatures we have to change the carrying heat uid to food use thermal oil.We have designed a hydraulic system that passes on the outside of the building so that we can guarantee the safety of the user. Again we meet an application for domestic building born from industrial components.

13

Hot Cold

Warm sanitary waterThe thermal system installed in the roof undertakes the production of warm sanitary water with up to 60 % coverage. To know the volume needs of the building we have calculated the needs for domestic appliances and recirculation.

AsAs for the recirculation of the warm sanitary water circuit, we thought of minimizing the losses that could be produced by this system. For such an effect, the whole installation of warm sanitary water is hot proof and we have total access to the recirculation from the home automation. This allows us to have as much as we need recirculation. We have the possibility of deactivating the automatic recirculation and activate it manually ac-cording to our needs.A circuit as small as the one that we have in our building might be re-circulated in seconds. This recirculation mechanism will avoid unnecessary losses of water while we wait it warms up.

Air Conditioning SystemsAir conditioning is one of the points where the EBSKA House has tried itself to be placed in the forefront of the energetic saving, betting for solar cold systems (absorption machines), and distributing cold by radiant systems. This combination allows reducing the energetic consumption.

INDUSTRIALIZATION AND VIABILITY OF MARKET

AdaptationAlong history, the house has gone constant adapting to the needs of the persons who live in. At present, the concept of housing is mo-died little by little. It is increasingly small, with better articulated spaces and more useful.

People, due to questions of work or study became more nomadic, change place very often, for what our type of housing also changes along a life. The needs and the priorities are different as we advance in age.

In youth we need a house that covers our needs, a minimal, basic and very functional house. When we have middle age we increase the number of users in the house for what it also increases of size. But when we become old we return to a small house with spaces that solve our basic needs.

Facing the current housing problem, all over the word, there are new attempts every day of doing that the technology appears as a so-lution giving place to attainable prices, to a great adaptability, exibility and customization of the housing.
