Overheating & comfort
TM59 overheating assessment
A more detailed view of how the proposed home responds to summer conditions.
What this service helps you do.
Dynamic thermal modelling considers the building, its glazing, shading and ventilation over time. Ordellis uses a project-specific TM59 assessment scope to evaluate residential overheating risk and support coordinated design decisions.
What’s included.
- A thermal model based on the agreed drawings and specifications.
- Assessment of the agreed occupancy, glazing and ventilation assumptions.
- Overheating results and a report explaining the modelling inputs.
- Review of agreed design options where changes are needed.
What we need to get started.
- Dimensioned plans, elevations, sections and orientation.
- Construction build-ups and glazing thermal and solar properties.
- Shading, window opening and ventilation information.
- The agreed design constraints and relevant project context.
Results depend on the model inputs. Changes to layout, glazing, shading or ventilation should be reviewed against the assessment before the report is relied on for the revised design.
Your questions, answered.
What is the difference from the simple method?
The simplified route checks specified design parameters. Dynamic thermal modelling evaluates the building’s thermal response over time using an agreed modelling methodology.
Can you compare design options?
Yes, where included in the quotation. Agree the alternatives and revision allowance at the start so the modelling work remains focused.
