Dynamic thermal modelling / UK
See how your building performs, hour by hour.
Send us your drawings and MEP design. We model the scheme in IES Virtual Environment, run dynamic simulations and return the Part L, Overheating, Plant loads, BREEAM and reports your project needs.

How it works
From drawings to a report you can submit.
We confirm the right assessment route with your project team before any modelling starts, so no work is wasted when Part L, Part O, energy statements and BREEAM overlap on the same scheme.

The UK climate
Tested against more than one summer
Overheating risk depends on the weather you test against. We run CIBSE design summer years for your nearest weather station, from a typical warm summer to a long hot one.
