Multi-family social housing building divided in two blocks due to terrain topography, with 15 apartments total (5 per floor across 3 residential levels plus basement garage).
The main façade is east oriented, with unique entrance, while the west façade features open common corridors.
The building underwent deep renovation with timber prefabricated multifunctional façade (PMF) on 1st and 2nd floors of east façade, integrating PV panels, ventilation systems, and new balconies.
The U-value of the existing façade amounted to 0.64 W/m²K before renovation.
After renovation, significant gains were observed:
- Ground Floor: 0.37 W/m²K (with conventional ETICS)
- 1st-2nd Floor: 0.16 W/m²K (with PMF panels - Prefabricated + Existing wall)
