Abstract
Purpose In the light of projected climate change impacts on buildings and their occupants, climate change adaptation for built environment to climate change is crucial. The risk of overheating is a key concern, particularly given its effect on heat-related health problems for elderly people. The purpose of this paper is to propose, test, and evaluate the strategies for climate change adaptation to minimise present and future risks of overheating for a new purpose-built care home and extra care accommodation near York. Design/methodology/approach The overheating risk was assessed through dynamic simulations, using probabilistic projections for 2030s, 2050s and 2080s. Suitable adaptation measures were tested and compared using industry metrics. A stakeholders' workshop compared the relative effectiveness of the identified measures and made a broader evaluation using defined criteria. Highest-ranked measures were combined into “adaptation packages” in order to populate adaptation timelines for the project. Findings Results show that the original design presents a severe overheating risk. Increasing thermal mass and slightly improving ventilation are adequate for the 2030s; however solar shading and further improvements of ventilation are necessary for the 2050s. The stress test revealed that even the most effective passive measures combined would be insufficient to maintain comfortable conditions by the 2080s, and mechanical cooling would be needed. Originality/value The comparative analysis of adaptation measures using normalised CIBSE TM52 criteria improved risk communication and engagement with the client and the design team. The integration of quantitative and qualitative evaluation criteria led to an appropriate and timely strategy for adaptation.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
