Objective
To demonstrate by use of various solar passive measures and active solar systems that the energy consumption can be reduced by 80% compared with conventional houses.
Twenty five semi-detached low cost houses (140 m2 living space plus a garage) are built on two different sites in the Walloon Region.
The project involves the following passive systems:
- water-tight insulation : quasi-total elimination of thermal bridges, adequate localisation of dew-points,
- maximum exposure of south side wonindows (30 m2),
- thermal storage in the building structure.
The active systems are:
- a composite slab comprising a heat exchange layer made up of pebbles (12 m3) and sandwiched between two heat storage layers of concrete. (This slab forms the ground plate of the house)
- a controlled ventilation system which operates in different modes: air renewal - composite slab charging - summer and winter conditioning. The following technologies are used:
- special heat recuperation system for the thermal mass of the building by air pulsation.
- possible option, special heat-exchanger for hot water production.
