Original situation

A non-residential building from the 1970s on the outskirts of Coulanges sur Yonne, used as a old age home

Renovation approach

In order to speed up the renovation, prefabricated elements are being applied as often as possible. The renovated part will meet the EnerPHit Standard whereas the new build will reach Passive Classic level.

Modernisation proposal

Semi prefabricated complete retrofit. The two storey building to the left of the main building is being renovated while a new building is being added to the right.

Efficiency improvement

The renovated part will meet the EnerPHit Standard resulting in a factor 7 reduction in heating demand; the new build will reach Passive Classic level. Before the renovation: Bill basis: Electric consumption: 165 kWh/m2.a (78.000 €/a)
