Energy-intensive building

General information

This project consists of implementing the thermal renovation of this 1970s residence, which has an 8-storey bar (building A) and two 6-storey plots (buildings B1 and B2).

This ambitious operation relating to buildings A and B1 includes the renovation of all the facades with thermal insulation from the outside, the replacement of the exterior joinery (private and smoke extraction skylights), the insulation of the roof terraces, the low floors on the car parks and roller shutter boxes, the installation of a VMC hygro B, the installation of thermostatic valves on the radiators, the cooling of the halls and their accessibility to PMR by external landscaped ramps.

The presence of asbestos in the exterior joinery joints and in the mosaic glue had an influence on the implementation of the ITE and on the replacement of certain windows.

Contest

Reasons for participating in the competition(s)

Cette opération a été exemplaire sur le niveau des performances visées (39 % de gain énergétique sur le bâtiment A et 44% sur le bâtiment B) et atteintes au pourcent près après comparaison entre prévisions et factures, avec une approche globale sur les parois opaques et vitrées, sur la ventilation et le chauffage et sur la mise en conformité des accès. Le défi a été de préserver et valoriser l'esthétique remarquable et le vocabulaire architectural des façades à un coût maitrisé.
