A new Building Regulation to mitigate overheating applies in England from June 2022. A requirement of the regulation is that the strategy to mitigate overheating must be usable, considering occupants' safety and comfort. If internal noise levels exceed 40 dBA LAeq, 8 hr, or 55 dB LAmax more than 10 times a night, then windows cannot be assumed to be open during the night time period. This paper discusses a triage process to consider the noise risk, the practical methods and uncertainties in the noise survey, environmental noise modelling, calculation of facade sound insulation with windows sufficiently open to mitigate overheating, and demonstrating compliance. Potential solutions for natural ventilation and mechanically assisted ventilation are outlined. Until now, the environmental noise impact on new dwellings has been controlled through the planning regime, where environmental health officers have acoustics expertise. The Building Regulations are enforced by building control officers, who may have little or no training in acoustics. More than 30 % of existing dwellings in the UK are exposed noise levels that may preclude reliance on opening windows to mitigate overheating in future dwellings. [ABSTRACT FROM AUTHOR] |
