Low energy house in Seest

The low energy house in Seest is an architectural designed standard house with an extraordinary low heating consumption. It was built in Seest in Kolding but can be built on any building site. The house is not experimental and can be compared to any other standard house construction.
 

The goal is to demonstrate that stylish architecture and prefabricated construction can be combined with an energy design to a price on the levels of any other standard houses.

Energy consumption
The low energy house uses 2.5 litres of oil per m2 per year for room heating corresponding to a monthly heating bill of 22 euro. This also includes the energy use for the ventilation system. It is 107 euro less per month compared to a normal house that uses 14 litres of oil per m2 per year.

Technical solutions
The low energy house only used geothermal energy for heating. Rockwool International A/S and the department of Civil Engineering at the Technical University of Denmark have developed windows together that reduce thermal bridges between walls and windows. Additionally, the thermal bridges at the foundation and the facade are reduced by external insulation and hermetic seams. A ventilation system ensures ventilation with heat recovery. The house is insulated with 200-550 mm in the various constructions.
