The Ru de Buzot residence is located in Saint-Germain-en-Laye. Composed of 3 buildings, not exceeding 4 levels on the ground floor, these small buildings are scattered among an island of greenery.
The Syndical Council chose the REANOVA company which was commissioned to carry out:
- An energy audit in 2015 including proposals for different work scenarios;
- A design mission with financial support;
- The vote on the work at the General Assembly on November 8, 2016 for a period of 24 months; 2018: delivery of works
Following the completion of the audit, the condominium therefore embarked on a complete renovation program including:
- the replacement of the original private joinery and rolling shutters;
- installation of thermostatic valves;
- insulation of lower floors;
- insulation of roofs and repair of waterproofing;
- the installation of a low pressure VMC;
- the thermal insulation of facades from the outside;
- the replacement of collective joinery (hall doors + fire door in the basement).
