The first Passivhaus reform in Spain, Passivhaus appartment of Miren Rivas

This project stands out not only as it is the first Passivhaus renovation in Spain, but also due to the complexity associated with renovating a single flat in an entire building. To obtain Passivhaus standard, efficient solar shading is key. This Passivhaus flat consists of an interior wall cladding with thermo-acoustic insulation, high efficiency windows and, above all, airtightness.

Griesser’s solar shading solution played a key role in achieving energy efficiency, preventing overheating and allowing natural light to be controlled in the interior of the house.
