Overheating in buildings is an increasing concern in the United Kingdom, driven by climate change and the associated rise in internal temperatures. Whether you’re planning a new non-domestic building or managing an existing property, our Thermal Comfort Analysis using CIBSE TM52 can help assess the risk of overheating and ensure thermal comfort throughout the year.

TM52 Thermal Comfort Analysis is designed specifically to assess and mitigate overheating risks in non-domestic, “free-running” buildings, whether existing or proposed. Using the CIBSE TM52 methodology, this analysis evaluates three key criteria: hours of exceedance, daily weighted exceedance, and upper limit temperature, to assess the thermal comfort of your building.

Our expert sustainability consultants use dynamic simulation modelling to asses thermal comfort levels and predict overheating risks in your building. This helps identify strategies to mitigate overheating and ensure that your building meets the necessary thermal comfort standards.

This analysis can be applied during the design stage of new buildings or can be applied to existing properties, especially those experiencing overheating risks. This comprehensive analysis provides a clear report on potential overheating risks and offers practical strategies for mitigation, from design modifications to operational adjustments.

The findings will guide decisions around building upgrades and adjustments, ensuring your building remains comfortable, energy-efficient, and compliant with the necessary thermal comfort standards.

Surveying an active shopping centre is logistically complex, but Building Energy Experts handled it with precision. Their report cut through the environmental variables to provide a clear distinction between maintenance quick-wins, like resealing doors, and the capital investment needed for insulation. It provided the exact technical evidence required to inform our roadmap to an EPC B rating and justify the retrofit budget.

In delivery of the Warm Homes: Local Grant programme in Shropshire, Building Energy Experts (BEE) have acted as invaluable partners to the Council. Their expertise in reviewing installer designs and liaising with our consortium of local installers has ensured the technical compliance and appropriateness of measures installed under the scheme.

The Council’s goal was to find a critical friend that ensures best practice and full PAS2035 compliance under schemes it delivers – BEE have brought this in spades, accompanied with a professionalism and pragmatism that has been indispensable in navigating the nuances and complexities of local authority led, domestic retrofit schemes. I would highly recommend engaging with BEE to any council or social housing provider considering an independent retrofit coordination model.

I should like to say thank you so much to Rich and the team at Building Energy Experts for their efficiency and helpfulness in completing our commercial EPC survey in record time.

Assessing a historic property like Walton Castle requires real expertise, and your team delivered exactly that. Not only did they complete this survey with a very quick turnaround but they went above and beyond by providing extra information and guidance which has been extremely helpful.

We are delighted with the final result and once again thank you from both myself and the team at Walton Castle.

What a great service you provided! As Self-Builders, with a great deal of red tape/bureaucracy to satisfy, you truly made this a real ‘value-add’ and reasonably priced exercise. We thought we were in reasonably good shape (having taken a lot of care and time on our build), but the checklist provided in advance of the test and the report post test, were really helpful in making improvements to the fabric of the building.
