Energy-intensive building

A wood building in the forest

Near the scenic Klitmøller in Thy, is built the Nature Agency's official residence. The local forest runner lives with his family in a fine and simple wooden house, which BJERG designed in 2019.
The house blends naturally into the surroundings without disturbing either people or nature. Even after work, the forest runner can enjoy the beautiful nature, as the surroundings enter the house's living room and kitchen via the large window sections.
The house in Thy is built according to passive house principles and has a CO2 footprint of 5.1 kg CO2/m2/year, which is significantly better than the "voluntary sustainability requirement" of 8 kg/m2/year, which has been decided from 2023.

A low CO2 footprint

The house's low CO2 footprint is due to both design and choice of materials. A significant climate reduction already occurs at the start of the design process, when we orient the primary rooms with large window sections to the south. This reduces the need for artificial light and heating, and thus the house's total energy needs are reduced.

Wood is used as the primary material, and instead of glass wool we use wood fiber for insulation, as it can absorb and transport moisture to a greater extent. The house has a tight and well-insulated climate screen, as it reduces energy demand and CO2 emissions.

The dense building shell also provides a healthy indoor climate without thermal bridges.

The Danish Nature Agency is enthusiastic about the home: "In Thy, we have not only got a beautiful home. But also, a home that really improves on a CO2 account, has a healthy indoor climate and low costs for operation and maintenance. We have chosen to build in wood to emphasize the Norwegian Nature Agency's roots, and find that BJERG Architecture with a simple design has managed to make the house blend elegantly into the surroundings," Kim Røjgaard, head of finance, Norwegian Nature Agency.

Product

Compact P Nilan

Product category : Structural work / Passive system

The Compact P is a ventilation and heating system that provides with ventilation, heat recovery and domestic hot water production. It ensures a daily renewal of the air by evacuating dust, odors and excess humidity for a healthy and pleasant indoor atmosphere. When it is hotter inside than outside the house, an integrated bypass lets fresh air in directly to cool down as much as possible without using additional energy.
