Energy-intensive building
  • Certified BBC Effinergie 2005
  • LQE 2013 prize winner

This project replaced a fallow land (former car garage) located in the city center of Saint-Max. The objective was to create three individual units for rental under a law operation "Scellier green". The accommodations received the BBC (Low Energy Building) RT 2005 label and are accessible for disabled people. The desire was to highlight the wood construction in a project of atypical houses while densifying the plot. The use of recycled products was favored by the fact that contractors were also entrepreneur who made the structure.

Hygrothermal confort
- Search for inertia (slab + screed, high density insulating)
- Efficient airtightness, elimination of thermal bridges
- Perspirates walls
- Blind integrated to double glazing
- No felling of cold walls
- Overventilation by opening the windows
- Double flow CMV with enthalpy regulator

Acoustic confort
- Separation of structures between the houses
- Reinforced insulation between party wall

Visual confort
- Terraces opening on the inside gardens
- Indirect lighting
