04n0e-sport and Step-2-Sport are EU projects developed under the Intelligent Energy Europe programme (IEE) with a common objective: to promote the energy renovation of existing sports facilities to pave the way towards nearly Zero Energy Buildings (nZEB). Sports facilities from 12 EU countries located in different climatic conditions are benefitting from the results of these projects. In total, 45 EU sport buildings from different types (swimming pools, sport halls, gymnasiums, sport complexes, ice rink arenas and outdoor sport facilities) have been evaluated from the energetic point of view, and specific implementation plans have been defined, indicating the energy improvement measures to be implemented for achieving nZEB.

n0e-sport paves the way towards nearly Zero-Energy Sports Facilities by designing, demonstrating and communicating an integrated package of building renovation, new technology, energy saving methods and renewable energies. The project has now entered its third year. Each partner compared the outcomes from the energy audits with an extensive list of potential energy efficiency measures already completed in the earlier stage of the project to devise an Implementation Plan to one of more measures into each of their sports facilities. This Implementation stage of the project began earlier this year with partners identifying a range of energy efficiency measures including installation of energy monitoring systems, increased insulation in walls, installation of thermostatic valves on radiators, installation of PV panels, replacing lights with high efficiency or LED alternatives, boiler replacement, installation of pipe insulation and the list goes on. Installation costs and payback vary from region to region due to differences in energy costs and capital costs but energy efficiency and carbon savings are consistent with similar energy efficiency measures. For instance, in Portugal, capital cost for PV panels where €2,500, with a payback of 7 years and a CO2 saving of 15 tonnes, while in the UK a similar system would cost around €10,000, with a payback of 5 years (with government incentives) and a CO2 saving of 15 tonnes.

Within STEP-2-SPORT, a Roadmap towards nearly Zero Energy SPORT Buildings (http://step2sport.eu/?page_id=28) has been elaborated in order to support the refurbishment of the existing sport buildings through step by step renovation. The roadmap addresses the key steps to be considered by sport owners, but also sport facility managers, for achieving nearly zero energy sport buildings, including a description and the potential savings of a wide variety of energy improvement measures that can be implemented. After defining the Action Plans for the energy renovation, pilot sport buildings are currently implementing the some of the energy improvement measures proposed.
