Tailoring a future overheating risk tool for existing building design practice in domestic and non-domestic sectors

Research output: Contribution to journalArticle

Abstract

The Low Carbon Futures Project, as part of the Adaptation and Resilience to Climate Change (ARCC) programme, has developed an overheating tool, based on probabilistic UK Climate Projections (UKCP09), to provide design advice for building adaptations in future. For dwellings this tool, initiated by a single simulation, relies on just hourly climate information to predict the internal temperature profile and for a non-domestic building, it includes internal activity profiles to account for lighting, equipment, metabolic gains and air change. To produce a tailored design tool, a qualitative investigation has been carried out to understand current building practices. This investigation shows that the two sectors take a significantly different approach to design, where dynamic building simulation is rare for domestic developments. The diversity of the non-domestic building stock poses different challenges and requires more detail to perform any overheating analysis, with dynamic building simulation playing a key role. The suitability of this tool, and the need to balance complexity and detail with usability and applicability, will be explored for the two sectors, with an approach for implementing this in the future proposed. Practical application: This paper compares current overheating analyses, as reported through correspondence with practitioners, with a suggested approach for a more detailed future overheating assessment using the latest climate projections. The required steps to bridge the gap between current and possible future design methods are explored for both the domestic and non-domestic sectors, with a prototype tool proposed that has been formulated with the aid of industry feedback. The described project is therefore able to translate complex building and climate science into an approach that is potentially useful for building practitioners.
