Working in collaboration with Fletcher Bassi Architecture

With our expert support, ensure your building meets the new regulatory requirements of Part O Overheating. From design to final approval, our team guides you through the Part O compliance process, helping your new build residential project avoid overheating and achieve thermal comfort for all occupants.

By incorporating compliance strategies from the design phase, we provide detailed overheating risk assessments and comprehensive reports, minimising the risk of costly delays and design changes later on.

Why Part O Compliance Matters?

Overheating in buildings is an increasing concern due to rising temperatures, climate change, and stricter energy efficiency regulations. If you’re responsible for new build residential, including houses, flats, care homes, and student accommodation, understanding and meeting Part O requirements is crucial. While previous building regulations addressed heat retention during winter, Part O compliance focuses on preventing excessive indoor heat in warmer months.

Ensuring compliance helps you:

  • Prevent Overheating: Maintain a cooler indoor environment during hot weather
  • Enhance Comfort: Create a more pleasant and liveable space for residents
  • Mitigate Legal Risks: Avoid potential legal or reputational issues by staying compliant

With our guidance, safeguard occupant well-being and future-proof your building against evolving climate challenges.

Effortless Part O Compliance

At Energy Report, there are two methodologies available for meeting overheating regulations: the Simplified Method and Dynamic Thermal Modelling (TM59). Our expert assessors guide you through the best approach for your project, ensuring full compliance every step of the way:

Simplified Method

Best suited for simpler building designs where glazing and floor area limits are met. Key factors like building location, aspect and orientation, and window size and area are considered. This method is ideal for less complex buildings, with specific glazing and orientation limitations.

TM59 Dynamic Thermal Modelling

For more complex or larger projects, this flexible approach provides a detailed analysis to mitigate overheating risks, ensuring compliance with CIBSE’s TM59 standards. Using advanced thermal simulation software, the building’s internal environment is assessed to predict overheating risks based on factors likes building design, materials, climate data, and orientation.

How We Help You

We’ll work closely with you to:

  • Conduct Overheating Risk Assessments: Using TM59 or the Simplified Method, we’ll help you evaluate overheating risks and guide you towards solutions
  • Generate Detailed Reports: Our reports will clearly show how your building meets compliance and recommend strategies to reduce overheating risks
  • Prevent Delays: By addressing Part O requirements early in the design phase, we can help avoid costly and time-consuming changes later
