Delivering compliant, comfortable homes through robust overheating analysis.
Part O of the Building Regulations sets requirements to limit overheating risk in residential buildings, ensuring thermal comfort and occupant wellbeing, particularly in increasingly airtight, highly glazed homes.
MES Building Solutions provides overheating assessments and design advice, supporting developments from early concept through to compliance. Our approach focuses on identifying risk early and implementing practical, cost-effective mitigation strategies that integrate seamlessly with the wider building design.
We work closely with architects and project teams to ensure overheating risk is addressed alongside Part L, Part F, and façade design.
Overheating Strategy Advice
Early-stage guidance on glazing ratios, shading, orientation, and ventilation to reduce overheating risk
Part O Assessments
Compliance assessments using the simplified method or dynamic thermal modelling, depending on project requirements
Dynamic Thermal Modelling
Detailed simulation of internal temperatures to assess overheating risk in complex or higher-risk developments
Compliance Support
Practical recommendations and reporting to support planning, design development, and building control approval
Why Overheating Compliance Matters
As buildings become more energy-efficient and airtight, the risk of overheating increases, particularly in urban developments or highly glazed designs.
Addressing overheating early helps ensure comfortable, healthy living environments while avoiding costly redesign later in the project.
