Se trata de una vivienda, sostenible y ecológico, prefabricado con estructura de madera de entramado ligero, siguiendo los criterios y estándares bioclimáticos y constructivos PASSIVHAUS.

Rotllada Immobiliaris has developed a project in which Praxis carried out the Passivhaus consultancy. The services provided by Praxis included conducting Blower Door tests, designing the heating and ventilation systems, and performing thermal bridge calculations in 2D according to ISO 10211, evaluating both heat loss and minimum temperatures in all construction details. The Passivhaus certification was managed by Energiehaus.

The house, on the ground floor, has a usable area of 104 m². Its envelope consists of a timber frame structure for the walls and roof, with thicknesses of 140 and 220 mm, respectively, and mineral wool insulation between studs and beams. The exterior of the walls is finished with a ventilated façade system.

The windows are made of recycled PVC with triple low-emissivity glazing, and the cavities are filled with argon gas. As for the systems, heating and cooling are provided by an air-to-water aerothermal heat pump from DeDietrich, distributing heat through fan coils. Domestic hot water is also generated by this heat pump. For ventilation, the house is equipped with a mechanical double-flow system with sensible heat recovery by Siber.

In this case, the first house with the “PASSIVE HAUS CLÀSIC” Certification in the Osona region.
