For the first time in Barcelona, two usually separate programs are combined in the same building: sheltered rental housing with temporary accommodation equipment for the inclusion of the most vulnerable groups. The design of the set responds to three basic criteria:
1. Urban responsibility: we generate a public space and equip the ground floor with collective services. We organise the program in three vertical blocks, generating a public space as mentioned but with an interior street that separates and at the same time connects the accommodation with the homes and organises the accesses and communications allowing good cross ventilation throughout the whole.
2. Social responsibility: we understand the inclusion and accessibility of marginalised people in the broadest sense from the program. We match or compensate the conditions of the different parts of the program and dignify the accommodations without increasing the cost. It will be possible to reuse the building of temporary accommodation with another use and we obtain a balance between the parts of the program, because all the houses have the same qualities, there are no differences in orientation or sunshine.
3. Energy responsibility: we respond to the site and the program with a passive environmental attitude that reduces energy demand: good ventilation and good solar capture, saving energy. We get 100% of homes with sunlight. This makes it possible to activate the passive solar energy harvesting device of winter gardens, which cover 23% of the heating demand in winter. In summer, nighttime cross-ventilation of the conservatory and its daytime solar protection with shutters covers 43% of the cooling demand. This is complemented by high-efficiency systems such as aerothermia and a heat recovery system for double-flow ventilation, thus achieving an A energy certification for the finished building.
