Part O Compliance — simplified and dynamic simulation methods
Part O Compliance
We have expertise in overheating calculations using both the Simplified Method and Dynamic Simulation Method (dynamic thermal simulation) to enable you to fulfil the requirements of building regulations Part O.
Our assessors are experienced across the full range of CIBSE overheating standards and can also help you comply with the requirements of Building Bulletin 101 by the Department for Education and Skills (DfES).
Standards we work to
Part O
For dwellings
The simplified compliance route for new dwellings under Part O of the Building Regulations. A prescriptive method assessing solar gains and ventilation provisions to demonstrate overheating risk is adequately controlled.

For dwellings
A dynamic thermal simulation method for dwellings that provides a more detailed and flexible route to Part O compliance. Ideal for complex designs where the simplified method cannot demonstrate compliance.
Learn More 03CIBSE TM52
For commercial buildings
Dynamic thermal simulation-based overheating assessment for non-residential and commercial buildings. Evaluates thermal comfort using adaptive criteria to identify and mitigate overheating risk.
