In the heart of our bustling city, I had the pleasure of sitting down with James, a well-regarded expert in sustainable building practices and energy efficiency. Over a cup of coffee, we delved into the intricacies of thermal bridging calculations, a service offered by Focus360 that has swiftly become indispensable in the construction industry.
Successful low-energy building design hinges on careful planning. Focus360 Energy can help.
“Thermal bridging,” James began, “is essentially the phenomenon where heat escapes through points of contact between different materials in a building’s structure. These weak spots, or ‘thermal bridges’, can substantially undermine a building’s overall energy efficiency.”
As we talked, it became clear that eliminating these thermal bridges is not just about keeping a building warm. It’s also about meeting regulatory standards and ensuring long-term sustainability. James highlighted that with the removal of Accredited Construction Details (ACD) in 2022, builders and designers now face the critical task of creating third-party calculations for every junction or thermal bridge in a dwelling.
“Failure to do these calculations,” he explained, “means default values are used in the SAP (Standard Assessment Procedure) process, which often results in poor fabric efficiency ratings. Essentially, it compromises a building’s chances of meeting the minimum energy efficiency standards.”
James was quick to praise the expertise of the Focus360 team, who utilise specialist software like Physibel Trisco to simulate heat transfer through a building’s structure. “This software is particularly sophisticated,” he noted. “It takes into account a range of factors from materials used to geometry and boundary conditions. The output includes detailed graphs indicating temperature distribution and changes over time, highlighting potential hotspots.”
One of the most compelling aspects of our conversation was learning how these calculations directly impact real-world construction scenarios. James pointed out several common thermal bridges that often crop up during building projects. “Think about the junctions between the ground floor and walls, the areas around windows and doors, and even the roof at eaves or gable ends. These are all critical points where heat can escape if not properly addressed.”
The conversation veered towards the practical implications of thermal bridging calculations. James stressed that by identifying and addressing these weak points early, builders can not only enhance the energy efficiency of the building but also improve indoor climate comfort – a crucial factor for the occupants.
“Imagine you’re constructing a new home,” he said. “Using thermal bridging calculations, Focus360 can provide guidance on what kind and size of insulation to install. They can suggest areas where additional insulation or other measures might be needed. This proactive approach ensures that the building remains energy-efficient from the start.”
James’s insights reaffirmed that these calculations are not merely a regulatory checkbox but a vital element in modern construction. “In an era where sustainability is paramount,” he added, “services like those offered by Focus360 are invaluable. They not only help in meeting compliance but also contribute to creating buildings that are both comfortable and energy-efficient.”
As our conversation drew to a close, it was evident that the role of thermal bridging calculations in contemporary construction is both multifaceted and indispensable. By simulating how heat transfers through a building’s structure and providing actionable insights, Focus360’s service stands out as a cornerstone of energy-efficient building design.
Leaving the café, I couldn’t help but feel a deeper appreciation for the meticulous calculations that go into constructing a truly sustainable home. Thanks to experts like James and the dedicated team at Focus360, the future of building looks not just warmer but also brighter.
