Energy audits and energy performance certifications conducted in 26 EU pilot sport buildings within STEP-2-SPORT project have revealed significant potential energy savings, more than 11.000 MWh/year. With an investment of almost 6 million € can be achieved more than 1 million € per year of economic savings. The potential emissions reduction is more than 3.400 tonnes CO2 per year Energy efficiency measures and renewable energies have been proposed to enable the transition towards nearly zero energy sport buildings. Sports complexes, indoor swimming pools, gymnasiums and sport halls from 7 EU countries have been benefited from STEP-2-SPORT activities.
Pool heating, HVAC equipment, domestic hot water and pool pumping are the main energy users in buildings that have pools. Up to 50% of the energy used in pilot pools is for pool heating in order to compensate the heat losses caused by evaporation, radiation, conduction and convection. Dehumidification systems and filtration pumps are also significant energy consumers as they are usually operating a large number of hours. The energy consumption of indoor pools is highly influenced by the water pool surface and volume, as well as, the annual number of heating degree days. For sport buildings with no pool, space heating is often the largest energy consumer. Lighting accounts up to 25% of the energy use in sports halls and up to 20% in gymnasiums.
