• Ensures Compliance with UK Regulations: Part O is now a legal requirement for new residential buildings and major refurbishments in Sudbury. Conducting overheating calculations helps developers, architects, and builders avoid planning delays, fines, or the need for costly redesigns.
• Enhances Thermal Comfort for Occupants: By identifying overheating risks and recommending effective cooling strategies, these assessments ensure that homes remain comfortable throughout the year, particularly during heatwaves.
• Supports Energy-Efficient & Sustainable Design: Overheating calculations in Sudbury encourage passive cooling solutions, such as natural ventilation, shading, and thermal mass, reducing reliance on air conditioning and lowering energy consumption. This aligns with net-zero carbon goals and helps reduce the building’s carbon footprint.
• Improves Property Value & Marketability: Homes that are designed to mitigate overheating are more attractive to buyers and tenants. Energy-efficient and well-ventilated buildings often have lower running costs and a higher market appeal.
• Protects Health & Wellbeing: Excessive indoor temperatures can cause heat stress, dehydration, and other health risks, particularly for elderly residents, young children, and vulnerable individuals. Ensuring a home is well-ventilated and free from overheating risks enhances indoor air quality and supports occupant wellbeing.
• Reduces Long-Term Maintenance & Operational Costs: A building prone to overheating may require retrofits in the future, such as installing costly mechanical cooling systems. Early overheating assessments help avoid expensive modifications by incorporating effective design solutions from the start.
• Future-Proofs Buildings Against Climate Change: With rising temperatures and increasing urban density, overheating is a growing concern. Part O calculations in CO10 1 help ensure that buildings are designed to withstand future climate challenges, making them more resilient and adaptable.

Whether you’re working on new developments, high-rise flats, or housing conversions, Part O overheating calculations are vital for regulatory approval and long-term building performance.
