This extraordinary low-energy house was designed by the Danish architects JJW/Wissenbergand is particularly interesting because unlike almost every other low-energy house, this isn’t compact. Usually low-energy houses are more compact than traditionally houses, because the more compact the building envelope, the easier and more cost-effective it is to reach the Low-energy house Standard.
While designing the JJW/Wissenberg low-energy house the architects have used new technology to live up to the Low-energy house Standard, while keeping it spacious. The flat outer facade and high glass area/real estate also meant that the architects had to find alternative solutions and window concepts.
Getting as much sunlight into the house as possible was a high priority and therefore the house is built in 3 levels with large super-efficient windows from Rationel. At least 50 % of the energy supply comes from the windows which is the main reason why this project has reached the Low-energy house class 1.
Local development plans require that Minimum 50 % of the facade is wood. The ground level is concrete and 1. & 2. Floor’s façade is wood.
