Context and objective

Context :

► Too much domestic oil consumption every winter ► More and more difficult for our tenants to pay for it ► More and more difficult for our tenants to pay for it ► More and more difficult for us to find new tenants

due to a high level of energy cost

Our objective :

► The main objective of our project is to save energy,

not for us as an owner, but for the occupants

► Provide our tenants low energy consumption dwellings
