TM52 Overheating Assessments
In the UK’s dynamic commercial sector, thermal comfort is a critical operational concern. As global temperatures trend upward and climate change impacts intensify, building overheating has emerged as a significant challenge, with far-reaching implications for occupant productivity, well-being, and regulatory compliance.
The Unseen Discomforts: Overheating in Commercial Spaces
Overheating isn’t just about feeling a bit warm; it’s a complex issue with far-reaching consequences. When indoor temperatures soar, it can lead to:
- Discomfort and Reduced Productivity: Stuffy, overheated offices can make it difficult to concentrate, leading to decreased productivity and employee dissatisfaction.
- Health Risks: Vulnerable individuals, such as the elderly or those with pre-existing health conditions, can be particularly susceptible to heat-related illnesses.
- Building Damage: High temperatures and humidity can accelerate the deterioration of building materials and finishes, leading to costly repairs and maintenance.
- Regulatory Non-Compliance: While Part O of the Building Regulations currently focuses on new residential buildings, there’s a growing emphasis on thermal comfort in all types of buildings. Ignoring overheating risks could lead to future compliance issues and potential penalties.
Key Benefits of TM52 Assessments
Implement Effective Mitigation Strategies: Receive tailored recommendations for retrofitting solutions, such as improving ventilation, adding shading devices, or upgrading insulation, to create a more comfortable and productive environment.
Proactive Risk Management: Address potential overheating issues before they impact occupant well-being or lead to regulatory non-compliance.
Improved Occupant Comfort and Productivity: Create a comfortable and healthy working environment that fosters productivity and employee satisfaction.
Energy Efficiency and Cost Savings: Identify opportunities to optimize energy use and reduce operating costs through improved ventilation and insulation strategies.
Enhanced Marketability: Demonstrate your commitment to occupant well-being and sustainability, making your building more attractive to potential tenants and investors.
TM52: Your Building’s Thermal Health Check
TM52, also known as CIBSE TM52: Methodology for the Calculation of Energy Consumption of Buildings and their Services, is a specialized assessment that evaluates the risk of overheating in your existing commercial building. It goes beyond simple temperature readings, using dynamic thermal modelling to simulate how your building will respond to various weather conditions and occupancy patterns.

Understanding the Overheating Criteria: The TM52 ‘Comfort Test’
The TM52 assessment isn’t just about numbers; it’s about ensuring your building provides a comfortable and healthy environment for its occupants, even during those warm summer months. To achieve this, TM52 uses three key criteria to evaluate overheating risk:
Criterion 1: Hours of Exceedance: This criterion focuses on how often your building gets too hot. If the indoor temperature creeps above a certain comfort level (known as Tmax) by more than 1°C for too many hours during the summer months (May to September), it’s a red flag.
Criterion 2: Daily Weighted Exceedance: This one looks at the intensity of overheating on any given day. It calculates a value based on how much and for how long the temperature exceeds the comfort threshold. If this value gets too high, it indicates that the building is experiencing significant overheating on that day.
Criterion 3: Upper Limit Temperature: This is the absolute ‘no-go’ zone for temperature. It sets a maximum temperature that should never be exceeded, even for brief periods, during the summer months. If your building crosses this line, it’s a clear sign of overheating risk.
In a nutshell:
- Criterion 1: Limits how frequently the building gets too hot.
- Criterion 2: Limits how much the building gets too hot each day.
- Criterion 3: Sets an absolute maximum temperature that cannot be exceeded.
Understanding these criteria is vital for ensuring your building complies with TM52 guidance and provides a comfortable environment for its occupants. At Focus360 Energy, our expert assessors can help you navigate these complexities, identify potential overheating risks, and recommend effective mitigation strategies to ensure your building meets TM52 regulations at all times while staying cool and comfortable all year round.

Frequently Asked Questions
A TM52 assessment is a specialized evaluation that uses dynamic thermal modelling to assess the risk of overheating in existing commercial buildings. It helps identify areas prone to overheating and recommends solutions to improve thermal comfort.
Overheating can lead to discomfort, reduced productivity, and even health risks. A TM52 assessment helps you proactively address these issues, ensuring a comfortable and healthy working environment for occupants. It also helps you demonstrate compliance with energy efficiency regulations and avoid potential penalties.
If you’re experiencing overheating issues in your existing commercial building, or if you’re planning a new build, renovations or upgrades that could impact thermal comfort, a TM52 assessment is recommended. It’s also beneficial for demonstrating compliance with multiple energy efficiency regulations.
The assessment considers various factors, including the building’s fabric (walls, roof, floors, windows), ventilation strategies, occupancy patterns, internal heat gains from equipment and occupants, and local climate data.
Our accredited assessors will gather detailed information about your building and use advanced software to create a dynamic thermal model. This model simulates your building’s behaviour under different conditions, allowing us to predict overheating risks and recommend solutions.
The benefits include improved occupant comfort and productivity, reduced energy costs, compliance with regulations, enhanced marketability, and proactive risk mitigation.
The duration of the assessment depends on the size and complexity of your building. However, we strive to provide efficient and timely service, with minimal disruption to your operations.
If your building is found to be at risk of overheating, we’ll provide you with a detailed report outlining the issues and recommending practical, cost-effective solutions to mitigate the risks.
The cost of a TM52 assessment varies depending on the size and complexity of your building. Contact us today for a free, no-obligation quote tailored to your specific needs.
We offer a range of other services to support your building’s overall performance, including SAP calculations, SBEM calculations, air tightness testing, ventilation assessments, and energy audits.
