The Actions Plans defined during STEP-2-SPORT project have revealed that with a total investment of €9.3 million in the 27 pilot sport buildings, more than 12000 MWh/year can be saved through the implementation of energy efficiency measures and more than 3000 MWh/year can be produced with renewable energies. The energy improvement measures proposed are being implemented through a step-by-step renovation approach, which is an effective strategy for achieving Nearly Zero Energy Sport Buildings (NZEB) in cases when there is a shortage of financial resources.
Until February 2017, the investment made in the 27 EU pilot sport buildings has been around €1.1 million, achieving energy savings around 2000 MWh/year. A wide variety of energy improvement opportunities have been implemented so far, such as building envelope solutions (e.g. wall and roofs insulation, more energy-efficient windows), stratified storage tank system for hot water, energy-efficient pumps, LED lighting systems and occupancy sensors, efficient HVAC solutions and heat recovery systems for indoor swimming pools, and condensing and biomass boilers. By the end of 2017, almost €4 million will have been invested to improve the energy performance of pilot sport buildings, delivering energy savings higher than 6000 MWh/year, avoiding more than 1800 tonnes of CO2/year and saving more than €506000 per year.
This figure below shows the potential of energy savings detected in each one of the pilots. The bar in blue colour represents the final energy consumption before the renovation and the bar in green colour is the expected final energy consumption of the building after implementing all the measures proposed.
