As part of our ongoing commitment to helping architects, particularly when client budgets are ever tighter, we have developed a FREE Part O Calculator to provide a quick sense of whether a design is at risk of overheating - and what you can do about it.

Improvements in thermal efficiency and airtightness mean that overheating has become a significant challenge.

Non-compliance can result in planning delays so it is vital to mitigate the risk early in the design process.

If construction clients - from social housing providers and local authorities to commercial developers, housebuilders and landowners - need further help to achieve compliance, facilitate planning or undertake building services design, our technical engineers offer practical, performance-led support.
