69% less CO2 footprint than the Danish building regulation requires
These buildings is a climate-optimized passive house-plus project with 31 public housing units from 75 to 114 square meters. The homes replace a former town hall building on the site and are centrally located in Tarm by. Green outdoor areas create an oasis with rainwater beds and terraces between the houses. The building's CO2 footprint is 69% lower than the requirements of the Danish Building Regulations 2023. The climate-friendly homes are designed to be as energy efficient as possible.
Energy efficient dwelling in interaction with nature
The homes' low energy consumption is achieved, among other things with:
- An airtight construction, so that the houses have a very low heat loss from the walls, ceiling and floor.
- Tight and south-facing windows, so that the sun's heat is utilized.
- Controlled ventilation with heat recovery.
- Solar heating system used for domestic hot water.
The building is compact and open to the south and green outdoor spaces.
LAR elements such as rainwater beds and wet basins with reduced drainage ensure against cloudbursts and give the green areas a blue theme.
The LAR areas are planted with grasses. The homes are built in wooden constructions with facades in the natural materials slate and thermo wood.
Solar cells and a district heating integrated micro heating system contribute to the plus energy standard.

Ventillation Compact P Nilan
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.
