Measured Indoor Hygrothermal Conditions and Occupancy Levels in Arctic Swedish Multi-Family Buildings PDF

As requirements regarding energy efficiency are getting tougher, buildings in the arctic, as well as the rest of the world, need to be more energy efficient without compromising a good indoor climate. This paper presents measured moisture supply and occupancy level in a Swedish Arctic multi-family building. Measurements were done during one year with readings every 30 minutes in a building consisting of 51 apartments located in Kiruna at latitude 67.9°. Averages and typical variations on different timescales, year and day are presented for the different parameters as well as correlations between the parameters, for example moisture supply as a function of occupancy level. The results can be used when input data for simulations of energy use, moisture conditions and indoor climate are chosen as well as a reference to compare measurements to during verifications. In energy efficient buildings the occupants’ behavior generally has a high impact on the building performance which means that the characteristics of behavior related parameters are important to know.
