Energy retrofits – A call for healthier energy practices

Year: 2025

Type: article

Abstract: The impact of indoor air pollutant (IAP) exposure due to increased building airtightness to meet nearly zero energy standards remains largely underexamined. By extrapolating data from pre- and post-retrofit IAP measurements in a small sample of NZEB-retrofitted homes, we estimate potential health consequences from long term exposure at the measured concentrations. Health effects, driven mainly by PM 2.5 , may exceed current estimates for outdoor PM 2.5 exposure in Ireland. This study provides a practical example of the use of IAQ exposure data to estimate the likely health consequences resulting from changes in exposure due to deep energy retrofit. Comprehensive, large-scale studies are needed to fully understand the implications of energy retrofit measures on indoor air quality and public health.
