G house: Passive Design in Normandy, France | sustainable architecture | Scoop.it

The intermittent use of this structure near the Seine estuary, built as a holiday home, strongly influenced the environmental choices of the project. The challenge was to give priority to passive devices and architecture, offering a gain in terms of energy performance, but also for the comfort of the occupants.


The exposure has been a main priority : East-West orientation, oversized opening to the South, natural shades and solar control strategy, North side blind.

Great attention has been given to thermal insulation. Choosing wood slab, and a wood panelling structure insulated from the outside, has allowed us to obtain good levels of insulation and air tightness. Furthermore, the low-thermal-mass building, offered by the wooden structure is interesting in the context of a weekend home, that needs to heat up quickly, for short periods. A wood stove thus is sufficient to heat the home.Finally, the building is based on the dry process framework, with the benefits of prefabrication : quality building, swift assembly, and site protection...
