Thermal dynamic modelling services
Explore our expert consultancy offerings focused on TM59 compliance, overheating analysis, and dynamic thermal simulations tailored for architects and developers.
Overheating analysis
Evaluate building designs to prevent overheating, ensuring comfort and regulatory compliance with Part O standards using the simplified method.
From £150
The route most residential schemes take. Quick, inexpensive, and enough on its own where the design comfortably passes — and where it does not, it tells you that early, while changing the drawing is still cheap.


Dynamic thermal simulation
Advanced simulations predicting thermal performance to optimise energy efficiency in construction projects.
From £450
Where the simplified method says no, or was never going to apply. The building is modelled hour by hour across a full weather year, which is both the stricter test and the one that shows you exactly which rooms are the problem and what would settle them.
Psi values
Expert guidance and modelling of Psi values for use in dynamic thermal modelling and SAP calculations.
From £75 per junction
Calculated for your details rather than taken from the default tables, which are deliberately pessimistic. On a scheme of any size, modelling the junctions you actually build usually pays for itself several times over in the SAP result.

Energy modelling services
Detailed energy consumption forecasts to support sustainable development and efficient building operation. Priced per scheme — send the drawings and we will quote it.
How a job runs
You send the drawings
Floor plans, elevations, and the glazing and ventilation strategy if you have settled on one. A PDF set is fine.
You get a price and a date
Fixed, before any work starts, with the method we intend to use and why.
We model it
To TM59 and Approved Document O, with every assumption written down rather than buried in a software file.
You get the report
The result, the rooms that drive it, and — if it does not pass — what to change, in the order that will cost you least.
Tell us about the scheme
Send the drawings and a short description and you will have a price, and a realistic date for the report, the same working day.
