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

Bioclimatic strategies
With 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 artificial lighting in 20 %. Interior spaces can be opened to generate crossed ventilations in summer that means a reduction of 5 % in air conditioning 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, muffling 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 reflects 80 % of infrared emission, so that the quantity of radiation is prevented from achieve the insulating system, allowing to reduce enormously the heat load to offsetting. The lines of closets act like thermal additional mattress and installation areas.

The 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 recycling. There is a possibility to purify black waters for gardening. With the combination of these 3 systems: storage, purification and recycling we obtain an optimal configuration adapted to every climatological environment. Devices for water saving are implemented.

Materials and residues
The 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 quantity 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 separation of residues.

The great innovation of the EBSKA House is the implementation of active systems of high efficiency of industrial application adapted to the residential sector giving place to the SHS (System of Solar Hybridization) that combines the thermal solar power with the photovoltaic one. The thermal collectors of high efficiency developed by SRB allow to feed a system of " solar cold " capable of acclimatize 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 optimized 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.

Forced ventilations guarantee the quality of the air inside the building and an interchanger 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 efficiency of these domestic appliances on having reduced the need of water warming with other methods.
