Overlooking the bay of La Cocha is Villa Eulieta. This detached multi-family building has been designed under the Passivhaus Standard, although it has not been certified.
The building has a floor area of 441 m2 and consists of a first floor for garage and installations, and a ground, first and second floor with 4 dwellings.
The structure is made of reinforced concrete and Termoarcilla walls, wrapped in an XPS SATE, which forms a continuous insulation envelope. The flat roof is also insulated with XPS.
The airtightness has been solved by a layer of plaster plaster, protected from perforations by the installation chamber insulated with rock wool.
As can be expected, the views of the bay are translated into large windows facing north. To minimize energy losses, all windows are made of high-performance wood-aluminum carpentry and triple glazing with low-emissivity and argon gas in the chambers.
Indoor air quality is guaranteed with a double-flow mechanical ventilation system with high-efficiency heat recovery. The house has a community air-to-water aerothermal heat pump as a production system for air conditioning and DHW. Given its passive design and north orientation, the building is cooled exclusively by passive means.
