An Experimental Approach to Investigate the Effects of Infiltration Losses on Building Energy Performance

The energy losses, potentially reaching up to 20% due to infiltration around windows, have a significant impact. Given this high rate of energy loss, comprehensive research is essential. The experiments, conducted on eight different windows in three distinct buildings in Yalova, Turkey, aimed to investigate the effects of leaks in various types of windows situated on different facades and positions. Specifically, a 10-point measurement method developed within the study was employed to identify air leakage characteristics in micro-gaps at the frame joints, gaskets, and other potential leakage areas of windows. Subsequently, the magnitude of leakage was calculated, and the causes of leakage were examined. In the experiments, the highest measured infiltration rate was 6.3 m/s, estimating a total thermal energy loss of 1.95 kWh in a selected window. This research aims to provide valuable insights into understanding and mitigating the impact of infiltration on building energy performance.
