In a bustling café tucked away in the heart of London, I had the pleasure of meeting with Mark, a seasoned expert in the field of building sustainability and thermal comfort. As the sun streamed through the large windows, it seemed a fitting backdrop for our discussion about a subject that has been gaining significant traction in urban planning circles: Dynamic Thermal Modelling, as outlined by the CIBSE TM59 standards.
Successful low-energy building design hinges on careful planning. Focus360 Energy can help.
Mark, with his vast experience, painted a vivid picture of the importance and potential of this sophisticated methodology. “Think of dynamic thermal modelling as the unsung hero of urban development,” he began, his enthusiasm palpable. “Especially in cities like London, where the urban heat island effect can turn a pleasant summer’s day into an unbearable ordeal.”
The conversation turned to the specifics of the service offered by Focus 360 Energy, a company adept at employing this advanced approach. Mark explained that the need for dynamic thermal modelling arises from the intricate challenges posed by modern city living. With rising global temperatures and increasing urban density, the risk of overheating in homes has become a critical concern.
“Local councils are increasingly mandating these assessments during the planning process,” Mark mentioned. “It’s not just about meeting regulations; it’s about ensuring that the buildings we live and work in are comfortable and sustainable. For architects and developers, this means integrating strategies that can mitigate overheating right from the design phase.”
He detailed how the dynamic thermal modelling process involves a comprehensive simulation of a building’s thermal performance, accounting for various factors like occupancy, equipment heat gains, and lighting. “It’s not just about crunching numbers,” he said. “It’s about creating a living, breathing model of the building that can adapt and inform design decisions.”
Mark highlighted the specific criteria that Focus 360 Energy adheres to, ensuring that both naturally and mechanically ventilated homes maintain optimal temperatures. “For naturally ventilated homes, for instance, living spaces should not exceed 1°C over the desired level more than 3% of the time. And bedrooms need to stay below 26°C during sleeping hours, which is a crucial factor for comfort and health,” he explained.
For homes with mechanical ventilation, the standards are equally rigorous, with a cap on room temperatures at 26°C for less than 3% of the year. “These criteria aren’t just arbitrary,” Mark emphasised. “They’re grounded in extensive research and are crucial for ensuring that occupants aren’t just surviving, but thriving in their environments.”
The conversation flowed seamlessly into the benefits that clients could reap from such a detailed assessment. Mark pointed out that beyond compliance, dynamic thermal modelling offers a level of design flexibility that simplified methods simply can’t match. “It allows for a more nuanced approach to building design,” he said. “Developers can test different scenarios, tweak designs, and ultimately create spaces that are not only compliant but also innovative and responsive to future climate challenges.”
As our conversation drew to a close, Mark reflected on the broader implications of dynamic thermal modelling. “In many ways, this is about future-proofing our cities,” he mused. “As we face the realities of climate change, methodologies like CIBSE TM59 are essential tools in our arsenal. They help us move beyond reactive measures and towards a proactive approach to urban development.”
Leaving the café, I couldn’t help but feel a renewed appreciation for the intricate dance between technology and architecture, and the role experts like Mark play in shaping a more sustainable future. In a city constantly evolving, dynamic thermal modelling stands as a testament to the power of informed design and the pursuit of comfort in an ever-changing world.
