Enjoy a centenary house with the maximum comfort and minimum energy cost
The challenge was to refurbish a house built in 1918 maintaining both the original volume and facade whilst improving the thermal and acoustic comfort. The construction systems and materials used have made possible not only to achieve the goal but also to lower the energy demand from 171 kWh/m2 to 17 kWh/m2 annual (10 factor rehabilitation). Transforming a traditional existing building into a Passive House.
