Owner approach of sustainability

The goal was to build a passive building at the same price as a RT2012 (French thermal regulation for buildings) building. The construction budget is 570 € HT per m2. It should be noted that the client did not know what a passive building was when the prime contractor was chosen.

Architectural description

Metal structure, sandwich panels in front, joinery type stabalux triple glazing, waterproofing cover, n50 = 0.15

If you had to do it again?

Particular attention should be paid to summer comfort. The customer found the installation of external blinds superfluous, which will certainly be realized before the summer

Building users opinion

Perfect thermal comfort due to the absence of cold walls and the absence of parasitic air currents. A very pleasant acoustic comfort due to the very good air tightness and triple glazing.

Energy consumption

  • 59,00 kWhep/m2.an
  • 110,00 kWhep/m2.an
  • Other

  • 110,00 kWhef/m2.an
  • According to PHPP calculation:
    - Heating: 18%
    - DHW: 25%
    - Lighting and technical equipment: 48%
    - Auxiliary: 9%

    Calculation of energy Primary calculated according to the certified PHPP sheet (passive construction). Actual measured consumption The building at the time of the building permit was submitted only to RT2005.
