The building was built in 1959 and has undergone a renovation process to become more energy efficient and more modern in appearance. The thermal insulation of the building has been improved with new facades and insulation. Sunshine blinds have been integrated into the new facades, giving the original lustre and homogeneity.

Hybrid ventilation has been installed coupled with the installation of a condensing gas boiler. This has led to a significant reduction of greenhouse gas emissions from 61 to 17 kg CO2 Eq / m2.year.

Energy consumption

Primary energy need :  104,00 kWhep/m².an

Primary energy need for standard building :  250,00 kWhep/m².an

Calculation method: RT existant

CEEB : 0.0001

Breakdown for energy consumption : Hot water consumption now accounts for a major part of energy consumption because heating consumption has become very low.

GHG emissions

• GHG in use :  17,00 KgCO₂/m²/an
• GHG before use :  61,00 KgCO₂ /m²
• Building lifetime :  60,00 year(s)
