European Union | European Regional Development Fund Blekingearkivet Detailed description Detailed information on the practice Ronneby's second largest solar power plant of 35,000 kWh was assembled at the end of 2014 at Blekingearkiv's roof in Bräkne-Hoby, Sweden. The solar cells produce electricity to the archives and to the adjacent preschool Tingsgården. The archives in Bräkne-Hoby gather three functions – the Blekinge archives, the SVAR archives and the municipal archives. The renovation and extension of the archive began spring 2014. The building project was completed in the summer of 2015. The existing building has been renovated and has received an addition. The actual archive now has a newly built area of 1,000 m2 in two levels. The old archive building that has been renovated has an area of 600 m2. The old part is used for staff spaces and the new one houses the archive material. There is room for 10,000 meters of shelves space for material archival! Ronneby Municipality chose to invest in solar cells, when their buildings need to be able to produce their own electricity. In this case, the solar cells are located on the roof of the newly built archive building. The roof surface is 500 m2. The building is filled with archives, which means that electricity is needed during the summer to cool the building. In order to keep the records in the archive properly, it must not be too hot in the building. Even the older building with research rooms, conference rooms and offices is supplied with electricity from the archive. If the produced electricity is not used by the archives, it also supplies the pre- school, which is adjacent to the archive. Since the building has no storage facilities for electricity, surpluses are sometimes sold to the grid. During the winter, electricity is purchased. The roof of Blekingearkivet is a slab with slight slope. To optimize power generation, the solar cells are mounted on inclined positions. The advantage of such positioning is that it is a simple installation and they are easy to move if you need to access any part of the roof. European Union | European Regional Development Fund The new building is energy efficient and has heat recovery in ventilation. The buildings are heated with biofuel-based district heating from a small-scale central heating plant in Bräkne-Hoby. The image shows the new archive building with solar cells on the roof. In the background you can see the old archive building and the adjacent preschool. Picture: Ronneby municipality. The solar installation cost 52 000 Euro to build. 35% of the cost was financed through government grants, ie 18 000 Euro. Projecting was a small part of the Resources needed overall planning of the new archive building. It has not needed any resources for the operation of the installation. Timescale (start/end date) September 2014 – November 2014 Evidence of success (results The solar cell plant produces 35 MWh per year. The plant shows a good result achieved) and requires no maintenance. The solar cell plant is a good example of how solar energy can be produced for self-consumption and also contribute to electricity production for adjacent Potential for learning or transfer buildings. Since the archive has a cooling need during the summer, much of the electricity produced can be used directly in the business. Blekingearkivet is also a good architectural example where the solar cells fit well into the building. Contact details Name William Lavesson Organisation Ronneby kommun Email [email protected] .
