Part O: Dynamic Simulation

We offer Dynamic Overheating Simulations to support compliance with Part O of the Building Regulations, helping ensure your residential designs stay comfortable and safe in warmer months.

Dynamic Overheating Simulations are typically required under Part O when standard mitigation measures—like opening windows—aren’t feasible due to external risks. This includes situations where a building faces security concerns (such as ground-floor bedrooms) or air quality issues (like developments near busy roads or industrial zones). In these cases, natural ventilation may not be safe or practical, so a more detailed simulation is needed to show how the building will stay cool without relying on open windows. 

Using industry-standard modelling, we assess how factors like glazing, shading, ventilation, and orientation affect indoor temperatures—especially in bedrooms and living spaces. 

Our reports are clear, practical, and tailored to your project, giving planners and clients confidence that overheating risks have been properly addressed.
