This set is a clear example of green architecture.
LOG ID company, in collaboration with local firm of architects ASP, were the promoters of the project.
It is located in a residential area of houses, between the streets and Haldenstrasse Reuchenettsestrasse in Biel, a small town in northern Switzerland.
The site has a steep slope to the southwest.
The project aims to achieve high quality of life through the use of solar energy and cross ventilation.
The architectural concept is based on a solar greenhouse structure facing south, in combination with terraces and building mass.
The building consists of eight departments of various sizes. They are all facing south (warmer orientation) and feature a terrace.
The entrance to the building is located on the north side (cold orientation) and is made through a leafy corridor.
The apartments are located on floors broken in half levels. In the two lower levels, the departments are raised in a duplex. These, together with large double-height windows provide an interesting plant and a beautiful view of the city. The apartments on the third floor, also enjoy panoramic views through the glazed area and balconies.
The covered terraces up the exterior with the interior space.
Greenhouses convert sunlight into heat energy, which is used passively in winter, spring and autumn. In the absence of sunlight, it closes a glass wall between the building mass and glass surfaces, using a conventional heating system to heat the apartments.
Good ventilation in the winter months, through areas under glass helps reduce heat loss. The excellent insulation of the building minimizes energy consumption. The use of solar power covers approximately 20 to 30% of energy needs.
In the subtropical vegetation grows greenhouses providing a high quality of the building air. They absorb carbon dioxide and release oxygen, removing pollutants in the air. Planting is equipped with drainage and irrigation systems automatically. Rain water can be harnessed to irrigate plants.
