The co-ownership Lamartine / Stalingrad is committed to a package of works gathering no less than six different energy improvement actions!
The technical choices were directed towards the sharp reduction of the heating needs by a complete thermal treatment of the building envelope (facades, joinery, roofing, floor) before considering an improvement of the source of energy production by the installation of a gas condensing boiler. The quality of indoor air has not been forgotten with the implementation of moisture-sensitive mechanical ventilation in the homes.
The energy renovation allows to reach a level of performance "Building Low Consumption" with an energetic gain of more than 50%.
The ambitious renovation process could only be done with a strong involvement of the co-ownership, in particular of the union council which carried this project during many years. Numerous work meetings and educational presentations made it possible to obtain the co-owners' adhesion, in particular the collective replacement of all joinery.
The aid provided by the public authorities was decisive with a collective aid rate of 50% of the budget of the operation.
