Building regulations - overheating risk in new homes: research report

5. Conclusions

5.1 Dynamic thermal simulation has shown that the sample building typologies all pass Criteria B (bedrooms) for CIBSE TM59, with only dual aspect flats failing Criterion A for their living room spaces when using the Glasgow DSY1 2020 high emissions scenario weather file.

5.2 Given that the dual aspect flats only exceeded Criterion A to a limited extent, all of the passive risk mitigation packages evaluated in England and Wales should be sufficient for controlling the overheating risk. This paper provides commentary on the suitability of those packages with lowest capital cost.

5.3 A high-level comparison of historical weather data suggests that in Scotland southern inland locations (around Glasgow) have higher peak summer temperature compared to the rest of the locations reviewed. This suggests that the mitigation packages proposed in this paper should be suitable for controlling the risk of overheating for at least most locations in Scotland assuming that southern inland locations continue to have the highest peak summer temperatures.
