Cabana GR4 Passivhaus
PHI Low Energy Building certification for single family house with a treated floor area of 125.4 m², located in Castellcir, Barcelona. Designed by Lluís Jubert of Taller d´Arquitectura, promoted by Núria Grau and Jaume Ribas and built by Albert Fargas of Farhaus.
The construction system is lightweight timber frame, using low-emission, bio-based materials with low environmental impact to reduce the building’s carbon footprint and provide a healthy indoor environment. The high level of insulation, minimised thermal bridges and triple low-e glazing with Farhaus timber frames, reduce heating energy demand in the winter. In the summer, external blinds reduce solar gains and overheating. Mechanical ventilation with heat recovery is provided by a Zehnder ComfoAir 180 HRV.
As part of the Passivhaus audit, Praxis revised the calculations and design documentation presented by the Passivhaus Consultant, which include architectural and M&E drawings and reports, the PHPP calculation, the Blower Door test report, ventilation commissioning documentation and photographs of the construction process and the completed building.
