A passive house usually consumes slightly more energy than it generates. A zero or zero-energy house generates as much energy over a whole year as it consumes. An energy-plus house goes one step further!
An energy + house, generates more energy than it consumes. Among other things, it has large windows that provide lots of natural light, a heat pump and a roof fitted with solar panels and solar water heaters. The large stone walls in the house ensures that the temperature can remain as stable as possible. Clay finishing regulates the humidity. On the roof they’ve used paper insulation + a green roof filled with plants for extra insulation. Of course a house like this needs an excellent building envelope.
The basis for this energy-plus house is a solid passive house. Right from the design stage, a great deal of attention was paid to a compact construction, thorough insulat
