In the ever-evolving world of building design and construction, understanding the nuances of energy standards is crucial for ensuring the comfort and sustainability of new residential developments. To delve deeper into this, I sat down with Alex, an esteemed industry insider known for his expertise in sustainable building practices. Our conversation centred around TM59, a standard set by the Chartered Institution of Building Services Engineers (CIBSE), which focuses on evaluating the expected internal temperatures in residential-only properties.

As we settled into our discussion, Alex began by explaining the core of what TM59 offers. “The standard provides a framework for energy modellers,” he noted, emphasising its utility in outlining occupancy hours and the internal heat contributions from both occupants and equipment. These details are crucial for accurately predicting and managing building temperatures. “It’s not just about keeping buildings cool,” Alex said, “it’s about ensuring that every space within a building is comfortable and livable, day and night.”
One of the standout features of TM59 is its recommendations for window management based on internal air temperatures. Alex highlighted this point, saying, “Knowing when to open and close windows can drastically impact a building’s thermal performance.” He described how these seemingly small adjustments contribute significantly to maintaining an optimal indoor environment, especially during hot weather. The guide also considers heat gains from hot water pipework, an often-overlooked source of additional warmth in residential spaces.
The conversation drifted towards the specific criteria set by TM59 to mitigate overheating risks. “It’s about compliance,” Alex stated, “but more importantly, it’s about comfort.” By focusing on the duration that internal air temperatures exceed predefined levels, TM59 helps designers make informed decisions that safeguard against uncomfortable living conditions, particularly during sleep. “Nobody wants to toss and turn in the heat,” Alex added with a chuckle, underscoring the standard’s attention to both daytime and nighttime occupancy.
So, when should one carry out a TM59 assessment? Alex was quick to point out that timing is everything. “Ideally, these assessments should be done during the design phase,” he advised. This early intervention is crucial because it allows for adjustments to be made before construction begins. “If your design isn’t meeting the requirements,” he explained, “you have the opportunity to tweak things like window size, glass specifications, or even room orientation.” Such proactive measures ensure that once the building is up, it seamlessly aligns with the TM59 standards, preventing costly retrofits or modifications later on.
Our discussion also touched on which properties benefit most from a TM59 assessment. Alex laid out the scenarios clearly: “New residential properties, especially those in urban settings or large developments, should definitely consider it.” He went on to mention specific structures like care homes, student accommodations, and single-aspect flats. “These buildings often face higher risks of overheating due to high insulation and airtightness,” he explained. It’s not just the building as a whole that needs assessment but individual rooms too, including those with mechanical ventilation. “Imagine living in a flat where your living room turns into a sauna in the summer,” Alex remarked, illustrating the importance of comprehensive evaluations.
In closing our conversation, Alex reflected on the broader implications of TM59. “It’s not just a guideline,” he mused, “it’s a tool for creating spaces that people love to live in.” His insights painted a picture of TM59 as more than just a standard; it’s a blueprint for sustainable, comfortable living in the modern age. As I wrapped up our interview, I couldn’t help but appreciate the depth of knowledge and foresight that goes into creating spaces that not only meet regulatory standards but also enhance the quality of life.
In the world of construction and design, where the stakes are high and the impacts long-lasting, TM59 stands as a beacon for those committed to excellence in residential building. With experts like Alex leading the charge, the future of comfortable and sustainable living looks bright indeed.
