Abstract
Abstract
Indoor ice sports arenas are complex buildings that typically consume large amounts of energy. The energy is mainly used to freeze the ice rink and to keep the indoor air temperature and relative humidity at appropriate levels. Reducing the energy consumption and the carbon footprint from construction, operation, and material use, presents certain challenges from a building physics point of view. These challenges are especially prominent if the ice sports arena is operated in a climate featuring summer seasons that are warmer than the indoor air temperature and winter seasons that are colder. This study investigates the hygrothermal performance of an ice sports arena built using cross-laminated timber (CLT), located in Sandefjord, Norway. Hygrothermal simulations of the exterior wall were conducted and analysed using WUFI. Locally retrieved weather data is compared to WUFI simulations done in the design process, which were based on Moisture Design Reference Year (MDRY) files for Oslo. The moisture performance of the wall as built is investigated for three different indoor temperatures. Modifications to the wall to improve moisture performance are also investigated. Results indicate that the MDRY files do not accurately reflect the climate on site. The performance of the wall assembly is found to depend greatly on indoor temperature. For indoor temperatures colder than 12 °C, substantial condensation and moisture problems are predicted during summer. None of the investigated modifications are found to sufficiently increase the moisture performance of the wall. Drastic measures may be required to improve moisture safety.
