Our effect on the climate means that we have to find solutions for the future. The energy system of Bo01 proves that that it is possible to supply an entire city district with 100 % locally renewable energy. The district offers ways for people to live in a sustainable way, use public transport and economise on resources.
The Bo01 area is an important example for the future and the district has received a lot of international attention. The goal of the district is to have very low energy consumption, but at the same time, the residents demand a high level of comfort. They want to live well, even if they save energy. Better ventilation and more efficient buildings have led to much less energy being used for heating than in the average home. The residents can also monitor their indoor climate individually using different IT solutions.
Sun, wind and water
In the Bo01 area, the energy solutions were already integrated into the buildings in the architect´s original design . When the energy solutions blend into the environment, the overall effect is more visually satisfying. There are solar panels, solar cells and underground thermalmass storage facilities. In the Bo01 area, one of Sweden´s largest wind turbines supplies the area with electricity.
1 400 m2 solar panels in the area absorb the heat from the sun and warm the water in the pipes in the panels. The water is then used to heat the water in the radiators and in the taps.
The 120 m2 solar cells produce electricity in addition to the wind turbine. The solar cells are placed on semi-transparent glass roofs that let the light through to the balconies below. A water pump draws energy from natural water reservoirs, known as aquifers, in the underground rock. The system stores warm water from the summer to heat buildings and water in the winter and cold water from the winter to cool buildings in the summer.
The energy system was designed to produce enough heat and electricty for the original size of the area and since many years the the energy system deliveres what it promised. However the Bo01 area ended up larger than anticipated and also some of the houses consumes more energy then planned, therefore the renewable energy does not cover all the apartments need at this moment.
