Solar power is suited for the energy use of sports halls
VTT Technical Research Centre of Finland studied the energy consumption of indoor swimming pools and practice indoor ice rinks, and use of solar power in them. It is possible to cover 30% per cent of the energy need of such sites with solar power. However, the storage of solar energy poses a big challenge for increasing the use of solar power. Approximately 40% of the EU's overall energy consumption is taken up by buildings. The currently valid EU directive requires all new buildings to be nearly zero-energy (NZEB) by the end of 2020. The regulation is aimed at saving energy to mitigate
