Research examined the impact of the urban microenvironment on indoor air temperature, utilising a comprehensive dataset comprising over 2000 apartments in the Helsinki region, particularly during the heat waves of 2018 and 2021. Buildings were categorised into clusters based on factors including geographical location, green view index, floor area ratio, and proximity to the sea. 

Findings revealed that the urban microenvironment exhibited a maximum effect of up to 1°C on indoor air temperature. Notably, both the green view index and distance from the sea exerted the most substantial cooling influence, each contributing to a reduction of approximately 0.5°C. Moreover, the influence of urban microenvironment factors was more pronounced during short heatwaves compared to prolonged ones.
