This extraordinary low-energy house was designed by the Danish architects JJW
/Wissenberg in close collaboration with the owners of the house. Dardo, one of the owners, is an engineer and has actually drawn out the last details of the house himself.
The house is particularly interesting because unlike almost every other low-energy house, this isn’t compact. Normally low-energy houses are more compact than traditionally houses, because the more compact the building is, the easier and more cost-effective it is to reach the Low-energy house Standard.
Dardo and Lise were not willing to compromise and therefore the target was a bright and spacious house for them self and there child Lucca.
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 Windows & Doors. 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.
