As the sun poured through the café windows, John Williams sat down with Alex, an industry expert with over 20 years of experience in sustainable architecture and urban planning. The topic of conversation? The innovative service offered by Focus360: Dynamic Thermal Modelling according to CIBSE TM59 standards. With a cup of coffee in hand, Alex shared the intricacies and benefits of this advanced methodology.

“Dynamic Thermal Modelling, or DTM, is a significant leap forward in our ability to simulate and manage building temperatures,” Alex began. “Especially in urban areas like London, where the urban heat island effect can exacerbate overheating, this form of assessment is invaluable.”
Alex explained that dynamic thermal modelling provides a more detailed simulation than traditional methods. “It allows us to consider a multitude of variables – from occupancy patterns to equipment heat gains and even local weather data. This level of detail means we can predict and mitigate overheating with much greater accuracy.”
John noted that local councils in cities with high risks of overheating, such as London, often request these assessments during the planning process. “Absolutely,” Alex nodded. “Regulatory bodies are recognising the importance of these simulations. For developers, this means a smoother approval process and, ultimately, buildings that are more comfortable and energy-efficient.”
The conversation then turned to the specific criteria outlined in CIBSE TM59. Alex highlighted the two main types of ventilation systems: natural and mechanical. “For naturally ventilated homes, the guidelines are quite stringent. Living rooms, kitchens, and bedrooms must not exceed 1°C over the desired temperature more than 3% of the time. Additionally, bedrooms should remain below 26°C during sleeping hours for no more than 1% of the year.”
John raised an eyebrow, impressed by the level of detail. “And for mechanically ventilated homes?” he asked.
“In those cases, all rooms need to stay at or under 26°C for less than 3% of the annual occupied hours,” Alex responded. “This is where the real value of dynamic thermal modelling comes in. By using dynamic simulation software, we can fine-tune designs to meet these stringent criteria. It offers much more flexibility than simplified methods.”
Alex leaned in, emphasising the practical benefits for clients. “Imagine a residential development where overheating is minimised. Residents would enjoy a more comfortable living environment year-round. Plus, there’s the added benefit of potentially lower energy costs due to more efficient cooling systems.”
John could see the appeal. “So, Focus360’s team guides clients through this entire process?”
“Exactly,” Alex replied. “They are well-versed in the methodology and can provide expert guidance. From the initial assessment to the final report, they ensure that all criteria are met. This not only helps in gaining planning approval but also in creating buildings that stand up to future climate challenges.”
The conversation shifted to the broader implications of dynamic thermal modelling. “In the context of climate change, the ability to predict and manage building temperatures is crucial,” Alex noted. “As global temperatures rise, the risk of overheating in urban areas will only increase. Dynamic thermal modelling equips us with the tools to design buildings that can cope with these changes.”
John couldn’t help but reflect on the potential impact. “It sounds like a game-changer for urban planning and sustainable architecture.”
“It really is,” Alex agreed. “By adopting advanced methodologies like DTM, we can create more resilient, comfortable, and energy-efficient buildings. It’s about future-proofing our cities.”
As the interview wrapped up, John thanked Alex for the enlightening discussion. The expert’s insights had painted a clear picture of the value and importance of dynamic thermal modelling according to CIBSE TM59 standards. With a better understanding of this advanced methodology, it was evident that services like those offered by Focus360 could play a pivotal role in shaping the cities of tomorrow.
