CUBE Casas Pasivas

What CUBE Casas Pasivas does

CUBE Casas Pasivas builds single-family homes through traditional construction, meaning that most building systems are assembled on site. The company works through two approaches: the Passivhaus method and construction under Spain's Technical Building Code, using columns, one-way floor slabs and double-leaf exterior walls.

Both approaches incorporate renewable energy for heating and are designed to reach an A energy rating. The company explicitly distinguishes its work from prefabricated and modular construction.
