Thermal Comfort & Regulatory Compliance

Thermal comfort directly influences how people experience the spaces they live and work in. Poor design can lead to internal heat build-up, resulting in environments that are not only uncomfortable but may also fail to comply with current building regulations.

Our consultants assess thermal comfort in line with the latest guidance from CIBSE and relevant building standards, including Approved Document O and TM59. We provide a clear, evidence-based understanding of how your building performs under varying conditions, helping you demonstrate compliance with planning and regulatory requirements.

How We Can Help

We work closely with architects, developers, and design teams to integrate overheating strategies seamlessly into the wider design process. From early-stage feasibility studies to detailed dynamic simulations, our approach is tailored to suit your project’s scope and objectives. This includes:

  • Early design reviews to identify passive design opportunities.

  • Dynamic thermal modelling and TM59 assessments.

  • Bespoke recommendations for glazing, ventilation, and shading.

  • Support in responding to planning queries and local authority feedback.

TM59 Thermal Modelling Service

Our TM59 Thermal Modelling Service uses dynamic simulations to assess overheating risk in residential buildings. We evaluate internal temperatures under different conditions and provide practical recommendations for ventilation, shading, and glazing to ensure compliance with Approved Document O, TM59 guidance, and local planning requirements.

Dynamic Modelling Software

We use advanced dynamic simulation tools to model complex interactions between solar gains, ventilation, occupancy, and building materials. These simulations provide reliable, data-driven insights into how your design will behave across a range of future climate scenarios, ensuring your building is prepared for both current and evolving conditions.

Design Considerations In London

In London, overheating risk is a key planning concern, particularly for high-density developments and sites affected by the urban heat island effect. Local authorities increasingly require detailed assessments in line with the London Plan and GLA guidance. Our expertise enables us to provide targeted advice that aligns with local expectations, supports planning approval, and ensures comfortable, future-ready design outcomes.
