Spain’s First Certified Passive House Cuts Energy Use by 90%
Josep Bunyesc’s home consists of a ground floor, first floor and a basement, where the architect has his office. The wooden shelter with solar panels on its facade is orientated to the south to capture free passive solar energy while protecting itself from hot Spanish summers. The central patio creates a new internal southern facade, providing plenty of natural light, cross ventilation and views throughout the building interiors.
The construction was quick and utilized prefab OSB boards with 7.8 inch sheep’s wool insulation, and an external breathable surface to prevent condensation. During the summer there is no need to open the double-glazed windows as a free cooling system with ducts and airshafts lowers the temps and provides enough breeze. Efficiently-built, low-energy, modern and very affordable, Josep Bunyesc’s passive shelter in Spain is a family home for life.
