This is the good practice's implementation level. It can be national, regional or local.
About this good practice
The objective for the first buildings that have been built according to the quality program is that at least 25% of the building's energy requirements will be generated by renewable energy sources in the building. In practice, it means a focus on solar energy and geo-energy. Listerby School is
built with sustainable materials and it is partly self-sufficient for energy.
Although the school's surface has increased from 2000 m2 to 3000 m2, the school's total energy needs have decreased by a quarter. Prior to refurbishment, the school was heated with wood pellets, however due to the the rebuilding, it was decided to invest in solar cells and air heat pumps in substitution of the previous system. The building has solar panels, which gives about 40,000 kWh per year. The solar cells cover about 130 m2. In consequence, the energy cost of the entire school has fallen to a quarter compared to before.
In order to store energy in the form of heat, hot water tanks (from ECOScience) were implemented. The tanks store heat through energy efficient storage and optimal use of power sources, such as solar energy, heat pump and solid fuel.
The reasons to invest in solar energy in this particular property were:
- The goals of the municipality's quality program
- The support available for solar energy (such as grants)
- Self-produced renewable energy provides a better assessment within rankings and certification systems.

Resources needed
The investment in solar cells was 52 000 Euro. Ronneby municipality received 35% of the investment cost financed by government grants.
Evidence of success
The energy produced is about 40 000 kWh / year.
Potential for learning or transfer
Environment has been the focus of planning and construction at Listerby School. The experience gained in the project may be useful to other public or private actors who will build new ones or rebuild schools.
