Abstract

The rise in the global average air temperature is associated with more intense and frequent heatwaves. Summertime indoor conditions in residential buildings and the health of their occupants are influenced by this issue. It is, therefore, necessary to investigate overheating in residential buildings during climate change associated hot summers. In this study, the hourly indoor temperatures of 1054 apartments during the hot summer of 2018 are measured and analyzed in Helsinki, Finland. These apartments are different in size and age. The results showed that the indoor temperature in 98% of the apartments exceeded 27 C, 34% exceeded 30 C, and more than 5% of them exceeded 32C. Moreover, the degree hours above 27 C, 30 C, and 32 C are calculated. The results showed a significantly high risk of overheating in most of the apartments despite their room number and age differences.
