We have to acknowledge that overheating is a problem to be avoided and that we don’t need a heatwave to prod us into action, buildings can overheat for a multitude of reasons but the use of materials that help buffer heat preventing rapid transfer through the building can be used to substantially mitigate the risk. Typical areas that will benefit from such design are timber frame and lightweight structures, on a brick or masonry house this will usually be the roof. This is an important area to factor in heat buffering as it combines the warmest part of the house (hot air rises) with the largest solar collector on the building – the roof itself. Wherever possible design with overheating in mind, the Building Regulations do not require minimum standards for decrement delay and SAP is currently under review regarding overheating, so the choice to design and build to prevent overheating is one that rests solely with you.
