Description

Terrassa Haus is the first multi-residential building to receive Passivhaus certification in the city of Terrasa, Catalonia, Spain. The project was developed by Cambolico and designed by architects Antoni Espona & Xavier Torcal. Oliver Style and Bega Clavero from Praxis Resilient Buildings carried out the Passivhaus consultancy, HVAC design and Blower Door testing. The building achieved Passivhaus Classic certification.  

The ground floor offers 2 commercial spaces, with a further three floors with apartments ranging from 76 m2 to 154 m2. The building has a total floor area of 1142m2 and includes a communal co-working space, bike room, gym, and communal pool.

With an existing concrete structure that had been abandoned during the economic crisis of 2007, an external thermal insulation system with EPS insulation was applied over ceramic brick and rendered, with a further 5cm of Knauf Insulation mineral wool inside in the service void. The roof is insulated with XPS insulation. Rehau PVC windows frames with argon-filled low-e coated glazing make up the openings, with Swisspacer insulated glazing spacers to further reduce heat loss.

Heating, cooling and hot water is provided by individual Hitachi all-in-one heat pumps in each apartment. Similarly, mechanical ventilation with heat recovery is provided by individual Soler & Palau Passivhaus certified ventilation units, with intake air drawn in from the façade walls and stale air extracted to the roof with shared extract ducts.
