Energismarta ishallar

Abstract: This project has been regarding the ability to make Ice Arenas more Energy Smart. Using info and data from the A-hall in Gränby, Uppsala, different suggestions to make the arena better has been developed. There has also been taking under consideration whether the solutions are applicable in other Ice arenas in Sweden. The suggestions has focused on minimizing the energy usage, and if there is a realistic investment to install solar panels on the roof of the arena. The project has been based on theoretical studies, calculations, simulations and field trips. The project group has studied different areas of the arena in order to evaluate ways to improve the energy situation for each specific arena. The solutions has then been evaluated based on their respective applicability, energy saving capability, investment cost and payback time. Solutions found to be easy to apply with small investments were installing moving sensors for lights in dressing rooms and corridors and to make sure all doors to the arena are properly sealed. Some of the bigger investments included replacing glass in the windows, installing LED-tubes as light source and installing an airlock at the entrance. One conclusion to be drawn from the project is there are lots of ways to make an ice arena more energy smart, but the most important part is to anchor all the decisions with the working staff. If the new techniques are not properly taught and used, there will not be the required effect.
