Overheating assessment: Part O, TM59 assessment, TM52 assessment compliance

Strict regulations are in force to ensure the safety and comfort of people in buildings and Syntegra offers an overheating assessment package to guide developers during the project planning stage.

Buildings, both residential and business premises, must comply with Part O and sections TM59, and TM52 of the Building Regulations in relation to overheating assessment. These regulations are crucial in ensuring the safety and comfort of occupants in buildings, especially during periods of high temperatures.

In this section of our site, you will find an overview of the requirements and guidelines covered by these regulations. We will conduct such assessments for you to help plans win approval or help guide retrofit projects.

Part O:
Part O of the Building Regulations focuses on the conservation of fuel and power in buildings. It includes specific requirements for assessing and mitigating the risk of overheating in both residential and non-residential buildings. Compliance with Part O is essential to ensure that buildings are designed and constructed in a way that minimises the risk of overheating, thus promoting occupant well-being.

TM59:
TM59, also known as the Design Summer Years (DSY) overheating criteria, provides guidance on assessing the risk of overheating in residential buildings. It takes into account various factors such as building orientation, glazing, shading, ventilation, and thermal mass. Compliance with TM59 helps architects, engineers, and building professionals to evaluate and mitigate the risk of overheating during the summer months, ensuring a comfortable indoor environment for occupants.

TM52:
TM52 focuses on assessing the risk of overheating in non-residential buildings. It provides guidance on evaluating the thermal performance of buildings, considering factors such as solar gain, ventilation, and internal heat sources. Compliance with TM52 enables building professionals to identify potential overheating issues and implement appropriate measures to prevent discomfort and health risks for users.

Importance of Compliance:
Complying with Part O, TM59, and TM52 regulations is crucial for several reasons:

Occupant Comfort: By adhering to these regulations, building professionals can ensure that occupants are provided with a comfortable indoor environment, even during periods of high temperatures.
Health and well-being: Overheating can have adverse effects on human health, particularly for vulnerable individuals such as the elderly, children, and those with pre-existing medical conditions. Compliance with these regulations helps mitigate the risk of heat-related illnesses and promotes overall well-being.
Energy Efficiency: Assessing and mitigating the risk of overheating can also contribute to energy efficiency in buildings. By implementing appropriate measures, such as improved insulation, shading devices, and efficient ventilation systems, energy consumption for cooling purposes can be reduced.
Complying with Part O, TM59, and TM52 regulations is essential for ensuring the safety, comfort, and well-being of occupants in both residential and non-residential buildings.

By following the guidelines within these regulations, building professionals can effectively assess and mitigate the risk of overheating, creating a conducive indoor environment even during periods of high temperatures.
