Active Houses focus on the fact that the most sustainable energy source is the energy we do not use. So, the main focus in the design phase of the Healthy Home Townhouses was to reduce the energy demand by choosing the right shape and orientation of the house and active use of daylighting to reduce need for energy for electricity.
Healthy Home Townhouses have several heating sources. Floors are equipped with additional insulation and, in the bathroom floor, electrical heating cables. Domestic water is heated by solar collectors on the roof, while primary room heating is provided by electric radiators and a very well-proven technology: wood stoves. They provide pleasant and efficient heating on cold days, and sustainably sourced wood is carbon neutral.
Annual energy consumption is estimated to be around 51 kWh/m² per year. For comparison, an average terraced house in Norway consumes approximately 140 kWh/m² per year.
"Living in an energy-efficient building doesn’t have to be a complicated or expensive challenge. Nor do you have to sacrifice appealing architecture or fresh air quality indoors."
