EnEff-ice - Energy efficiency and dehumidification in indoor ice rinks

The research project Energy Efficiency and Dehumidification in Ice Rinks (EnEff-ice) is carried out by the University of Kassel, Department of Solar and System Engineering in cooperation with KSE Kassel Sport & Entertainment GmbH, which operates the indoor ice rink in Kassel. As a part of the research, the status of energy efficiency and air dehumidification in indoor ice rinks in Germany is investigated. In addition, two ice rinks will be analyzed by measurements and building simulations within a case study, as well as the indoor ice rink in Kassel. Possible energy efficiency measures will be developed and evaluated regarding a targeted CO2-neutral building stock in Germany and a cost-benefit analysis. In the ice rink in Kassel, exemplary measures for energy saving and air dehumidification are identified and evaluated. The feasibility of implementing individual energy-saving measures will be considered in detail. Depending on the measurement results obtained in the research project, an efficient dehumidification system will be integrated into the ice rink in Kassel to prevent condensation.

A building model for energy system simulations is being developed to assess various measures. With the help of annual simulations, the energy consumption and required indoor air dehumidification in indoor ice rinks are calculated. The models are used for holistic calculation and optimization of the building as well as for modelling single renovation paths. Based on the data collected for the ice rink in Kassel and other ice rinks, the transferability of the results to other ice rinks in Germany is ensured. To finalize the project, a guideline, and an online planning tool for energy-related renovation measures and implementation of dehumidification systems for ice rinks will be made and presented in a workshop.
