B+haus is a pioneering professional firm in Aragón specializing in the design of Nearly Zero Energy Buildings with the PassivHaus standard. Our expertise lies in creating passive houses that not only save more energy but also offer increased comfort and better indoor air quality compared to conventional buildings. We achieve this through high levels of insulation and advanced ventilation systems that filter the air before it enters the living spaces.

At B+haus, we are committed to creating sustainable and healthy living environments. Some of our notable projects include nZEB Torrebarajas, located in Zaragoza, with a built area of 480m² and annual heating and cooling costs of only €330 and €220 respectively. Another project is nZEB Torrero in the Barrio de Torrero, Zaragoza, boasting a built area of 90m² and heating and cooling costs of €170 and €40 per year respectively.

We have also successfully built the NZEB Ontinar, a 120m² single-family passive house in Ontinar de Salz, Zaragoza. In addition to residential projects, we also excel in designing energy-efficient public buildings such as the Pinseque Municipal Police Quarters. This project involved the renovation and expansion of two attached single-family homes, resulting in the new headquarters for the municipal police.

The building has achieved the prestigious PassivHaus Classic certification. Partner with B+haus for sustainable architecture that prioritizes energy efficiency, comfort, and health
