Reduced air volumes in spinning rooms combined with cooled ceiling

Abstract

In Norway 40 % of the energy used is related to buildings. The fitness industry has experienced a solid growth. From 30 fitness centres in 1960 to close to 1200 in 2018. The last ten years the numbers of fitness centres have doubled and over a million Norwegians are members of a fitness centre. Fitness centres and sport halls are buildings with high metabolic activity and demands large air volumes and cooling capacity for ensuring good air quality and comfortable temperatures. The need for large air volumes and cooling capacities is again leading to a high energy consumption in these buildings. As the governing recommendation is 250m3\h for rooms with high activity in fitness centres, like spinning rooms, this thesis will look at the opportunity to lower the recommended air volumes and yet keep the air quality at an acceptable level. This thesis will also apply radiant cooled ceiling as an alternative to fan coils as cooling.
