Energy / Heating:
Each house is equipped with an individual mechanical ventilation system D: the stale air is extracted in the wet rooms (bathroom, toilet, kitchen and laundry), while the healthy (fresh) air is conveyed in the living rooms (living room, bedrooms). An air-tightness test (blower-door test) is carried out at the end of the construction process.
The high-efficiency ventilation system in combination with the high airtightness of the house reduces the need for heating. And contributes to an easily controlled environment.
Water recuperation system:
The water consumption is reduced as much as possible thanks to the maximum use of the rainwater recovered and stored in the rainwater-tank with a capacity of 10.000L. Depending on the consumption, a saving of nearly 25.000L of water per year can thus be realized for a family of 4 people.
