In a recent conversation with Oliver, an esteemed energy consultant with over two decades of experience in sustainable building design, I delved into the intricacies and benefits of the TM59 assessments offered by Focus 360 Energy. The discussion was enlightening and underscored the importance of such evaluations in modern residential projects.

We began by discussing the foundational principles of TM59 as outlined by CIBSE. Oliver explained that TM59 provides a method for evaluating expected internal temperatures in residential properties. This method involves detailed data about occupancy hours, internal heat gains from equipment, and heat generated by occupants. “It’s like having a blueprint of how heat behaves in a building,” Oliver remarked, “allowing designers to anticipate and mitigate overheating before it becomes an issue.”
The conversation shifted to the practical aspects of conducting a TM59 assessment. Oliver emphasised that the ideal time to carry out such an assessment is during the design phase of a new project. “Think of it as a preventive measure,” he said. “By evaluating the initial design, you can identify and rectify potential overheating risks. This could involve resizing windows, tweaking glass specifications, or even altering room orientations to ensure compliance and comfort.”
One of the standout features of TM59, according to Oliver, is its detailed guidance on window operation based on internal air temperatures. “The standards provide clear recommendations on when to open windows, which is crucial for maintaining a comfortable living environment. It’s not just about having windows; it’s about knowing how and when to use them effectively,” he explained.
Oliver also highlighted the importance of considering heat gains from hot water pipework, especially in communal areas like apartment corridors. “It’s these little details that can make a significant difference in overall thermal comfort. By accounting for every possible heat source, the assessment ensures that no stone is left unturned.”
The criteria set by TM59 are stringent, focusing on the duration that internal air temperatures exceed predefined levels. This is particularly crucial for both daytime and nighttime occupancy. “Comfort during sleep is non-negotiable,” Oliver asserted. “The assessment ensures that temperatures remain within acceptable ranges throughout the day and night, providing peace of mind to residents.”
When asked about the types of properties that would benefit most from a TM59 assessment, Oliver was unequivocal. “Large developments and urban settings are prime candidates,” he said. “But it’s also invaluable for specific structures like Care Homes, Student Accommodation, and single-aspect flats. These buildings often have high insulation levels and air tightness, which can lead to overheating if not properly managed.”
Oliver pointed out that even individual rooms within these buildings, including mechanically ventilated spaces, should be assessed. “It’s not just about the building as a whole but understanding the thermal dynamics of each room. For instance, evaluating the living room in a house can provide insights into potential overheating risks and allow for targeted interventions.”
In summarising the benefits of a TM59 assessment by Focus 360 Energy, Oliver was clear: “It’s about foresight and precision. By conducting a thorough evaluation during the design phase, you can ensure that the building is not only compliant but also comfortable for its occupants. It’s a proactive approach to sustainable living.”
Our conversation with Oliver illuminated the critical role of TM59 assessments in modern residential design. The service offered by Focus 360 Energy stands out for its comprehensive approach, ensuring that every aspect of a building’s thermal performance is scrutinised and optimised. For developers and designers keen on delivering comfortable, compliant, and sustainable living spaces, a TM59 assessment is not just an option – it’s a necessity.
