    New Case Study: Grenoble's major private house renovation scheme


    GrenobleMurMur|Mur is a major private housing renovation scheme developed by the Covenant Signatory Grenoble Metropole. The first campaign aimed at reducing energy  consumption through the retrofitting of condominiums built between 1945 and 1975. 

    The project focuses on the thermal insulation of private housing to make them more energy efficient and consequently reduce CO2 emissions. In France, there is a need for locally motivated retrofitting projects, such as Mur|Mur, as the only incentives available are national tax credit and 0% rate loans. Insulating old buildings well reduces tenants’ heating and hot water bills, which make up 73% of buildings’ energy consumption. The implementation of this project also contributes to the alleviation of fuel poverty; which remains a critical social concern in France due to high energy prices.

    The project was funded by a combination of financial assistance from Grenoble Metropole and its partners together with financial incentives such as block grants and grants for low income households.

    4,467 dwellings in 84 condominiums were renovated, and in total 173 condominiums benefited from tailored support because of Mur|Mur from 2010 to 2014. The renovations resulted in 5,200 tonnes of saved CO2 emissions, which translates to savings of €135- 250 per year.

    Due to the success of the campaign, Mur|Mur was extended for the period 2016-2021. This new project allowed for new types of housing in the 49 communes making up the Grenoble metropolitan area: single-family dwellings and private co-owned multi-occupancy buildings. Following the financial challenges of the first campaign, Grenoble-Alpes Metropole now plans on strengthening assistance to retrofitting management with the objective of making it a permanent public policy.
