Energy-intensive building

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).
