Primary energy need
(Calculation method : Other )
The purpose of the project has pursued the overall performance in the building, to give it Energy Efficiency and accessibility from the street level to the floors of wich it was lacking. A thermal coating envelope of the entire building was added to lessen energy consumption and CO2 emissions, in addition to the elimination of thermal bridges. To verify the operation and effectiveness of the measures taken, a system that allows tele-reading has been temporarily installed, collecting and studying data, consumption and environmental conditions of the housing. This was performed remotely by the Department of Housing, Public Works and transport of the Basque Government.

Owner approach of sustainability
The purpose of this project is the concrete and comprehensive definition of the proposed energy rehabilitation and accessibility. Today, the building has energy and accessibility shortages that are intended to overcome, achieving a very high level of quality not only in formal or material issues, but also in the interior renovation of facilities. The purpose of the project seeks global action in the building, acting only in common elements and from the outside of the housing, preventing moving of the people living in them and attending at all times to the social and personal conditions of the population. The thermal coating of the entire building envelope is proposed to lessen energy consumption and CO2 emissions, ensuring proper disposal of thermal bridges. In this way and with proper ventilation detected condensations can be avoided. The closure of existing facade consists of one pole face brick from Palencia 25 cm., Air chamber, brick and plaster wall. Total 34 cm. It is not believed to have intermediate thermal insulation. The facade terrace areas will be solved through the SATE system with thermal insulation consisting of Alpharock rock wool or similar with a 120 mm thickness and a density of 155 kg / m3. The rest of the existing facade will be fixed by ceramic ventilated facade finishes with thermal insulation consisting of rockwool Ventirock 120 mm, thickness and density 100 kg / m3. The new pitched roofs will consist of: - forged existing concrete, - thermal insulation consisting of rockwool Alpharock or similar 120 mm in thickness and density 70 kg / m3, - panel sandwich plate lacquered gray with polyurethane insulation 8 cm. The new exterior carpentry will be of aluminum with thermal break: The glazing is double, with thicknesses 4/12/6; glasses located in areas with risk of impact will be security type 3 + 3. Currently there is no elevator, preventing accessibility from the street to each of the homes without having to use steps. Having 2 apartments per floor, the only possibility of inclusion of an elevator is on the outside, next to rear facade. To verify the operation and effectiveness of the measures adopted, a system enabling tele-reading, collection and study of data, consumption and environmental conditions of housing was performed remotely by the Department of Housing, Public Works and Transport of the Basque Government.
The draft ENERGETIC REHABILITATION AND ACCESSIBILITY block of flats located in Cuadrilla of Laguardia nº 2, 4 and 6, of Vitoria-Gasteiz was intended to act globally in a building that had huge energy shortages and accessibility that have now been corrected, achieving a very high level of quality not only in formal or material issues, but also in the interior renovation of facilities. The project tackled the thermal coating of the entire building envelope, both facades, roof and sanitary chamber of the ground floor to lessen energy consumption and CO2 emissions, ensuring proper disposal of thermal bridges. In this way and with proper ventilation, detected condensations are avoided. After the reform, the restored building has an adequate envelope to the limitation of energy demand needed to achieve thermal comfort depending on the weather, the intended use and the regime of summer and winter, with low economic cost of ownership. The characteristics of insulation and inertia, control of air permeability and exposure to solar radiation are regulated, and individual housing ventilation double flow with heat recovery offer high energy efficiency, resulting in the energy class "A".
