In Europe, there are around one million and half sports facilities, which represents 8% of the overall building stock. Most of them were built before 1980 and need refurbishment because no considerable changes have been made to the initial conditions. The STEP-2-SPORT project aims to support the refurbishment of the existing sport buildings through step by step renovation towards Nearly Zero Energy Buildings (NZEB), contributing to the EU energy objectives. The project covers the field Integrated Initiatives, focused on energy efficiency and renewable energy use in buildings.

The pilot sport buildings represent the following two types of sport facilities in different climatic conditions:

  • Swimming pools: focused on indoor swimming pools, because these facilities have higher energy consumption, caused mainly by the large amount of evaporation and ventilation needed.
  • Indoor sport facilities: include multi-function sports centers, community centers, gymnasiums (school sports halls), integrated sport facilities (with other functions integrated in the same structure), indoor ice rinks, etc.

Twelve partners from seven European countries participate in this project, that has officially started the 1st of March 2014 and its duration is 36 months.




i. Energy audit: to determine the energy use of the building and identify energy improvement opportunities
ii. Energy Performance Certification: to determine the energy rating of the building (A, B, C, D, E, F, G)
iii. Action Plan: definition of improvement measures to be implemented over the next 10 years in order to be a nearly zero energy building.
iv. Implementation of energy improvement measures
v. Guided Visit to the facility in order to make public the energy improvements implemented
vi. Technical training session to encourage the renovation of sport buildings
