Homes that overheat are at risk of posing a significant threat to the safety, health and well-being of those inside. With ongoing and upward-trending temperatures and trends in modern architecture, internal temperatures are reaching all-time highs in the summer months.
Focus 360 Energy understands the importance of rectifying these issues of overheating as quickly as possible for both the health and safety of residents but also for the cost-effectiveness of making changes to a building.
Safeguard inhabitants and your project with a TM59 overheating assessment from the specialists here at Focus 360 Energy.
What is TM59?
The assessment of overheating risk in homes was developed and published by CIBSE in 2017. The aim was to address the industry gap concerning overheating assessments of residential properties. Before the TM59 was developed, there were no specific industry criteria to base overheating in homes. As such, energy assessors and consultants would likely use differing model setups with no real benchmark on which to base the results.
Overheating Risk in Homes
Houses built prior to the early 1980s typically lacked insulation. With evolving standards and improved materials, today’s buildings boast much-improved insulation. Modern constructions also prioritise better air permeability.
Contemporary buildings frequently feature large glass facades. While this is advantageous for preserving warmth in colder seasons, it can pose a challenge in the warmer months, potentially leading to overheating issues.
Reasons Why a Home Could Overheat
Several factors contribute to the risk of overheating in homes. Homes with extensive glazing, especially south-facing windows, are susceptible to absorbing and retaining heat. Ineffectively designed natural ventilation, along with low air permeability rates, can hinder the proper circulation of air, exacerbating overheating concerns. Insufficient thermal insulation, low thermal mass, and single-aspect designs can also contribute to temperature imbalances. Additionally, properties connected to community heating systems and new builds may face challenges in regulating internal temperatures. Recognising these elements is crucial for implementing effective strategies to maintain a comfortable and well-ventilated living environment.

Standards Used in TM59
TM59 by CIBSE outlines a method for evaluating expected internal temperatures in residential-only properties. It provides essential data for energy modellers, such as occupancy hours, internal heat contributions from equipment in various rooms, and heat generated by occupants.
The standards also offer recommendations for determining when to open windows based on internal air temperatures. Additionally, they suggest heat gain considerations for hot water pipework traversing living spaces or communal areas like apartment corridors.
The guide establishes specific criteria to demonstrate compliance and mitigate the risk of overheating. These criteria focus on the duration the internal air temperature exceeds predefined levels, addressing both daytime and nighttime occupancy to ensure comfort during sleep.
When Should I Carry Out a TM59 Assessment?
Conducting a TM59 assessment holds utmost importance during the design phase of a new project. This evaluation becomes a crucial tool to ensure that your initial design aligns with the necessary requirements to prevent overheating in your building.
Initiating a TM59 assessment at the design stage is vital. If the preliminary design falls short of meeting the stipulated requirements, this early assessment allows for adjustments before the commencement of construction. Potential alterations may involve resizing windows, enhancing window opening capabilities, adjusting glass specifications to mitigate solar gain, or even modifying room sizes and orientations.
What Properties Should Have a TM59 Assessment?
TM59 overheating assessments prove invaluable for evaluating the risk of overheating in new residential properties, especially large developments or those emerging in urban settings.
The assessment is particularly relevant for diverse structures such as Care Homes, Student Accommodation, and single-aspect flats, where high insulation levels and air tightness may lead to overheating concerns. It is essential to extend the evaluation to individual rooms within these buildings, including spaces that are mechanically ventilated. For instance, assessing the living room in your house is crucial, ensuring a comprehensive understanding of the potential overheating risks.
