If you’re developing a new residential property in Coventry, an overheating assessment may be required to demonstrate compliance with Approved Document O (Part O) of the Building Regulations.
At One Stop Consult, we provide TM59 and Part O overheating assessments for new build dwellings, apartments and residential conversions throughout Coventry and the surrounding areas. Our experienced energy consultants use approved dynamic thermal modelling software to assess the risk of overheating and recommend practical design solutions where required.
Whether you’re at planning stage or preparing your Building Regulations submission, we can provide a fast, accurate assessment to help keep your project moving.
An overheating assessment is commonly required for:
- New build dwellings
- Apartment developments
- Residential conversions
- Buildings with extensive glazing
- Urban developments
- Schemes submitted under Approved Document O
Building Control or your SAP assessor will normally advise if an overheating assessment is required.
Our consultants create a thermal model of the proposed building using approved software.
The assessment considers:
- Building orientation
- Window sizes and locations
- Solar gains
- Ventilation strategy
- Internal heat gains
- Local weather data
- Occupancy assumptions
- Shading from surrounding buildings
Where overheating is identified, we can recommend practical design improvements to achieve compliance.
If the assessment identifies overheating risks, several design changes may help achieve compliance, including:
- External shading
- Solar control glazing
- Window size adjustments
- Improved natural ventilation
- Mechanical ventilation with summer bypass
- Alternative ventilation strategies
Our consultants will advise on the most cost-effective solution for your project.
Working with One Stop Consult means you’ll benefit from experienced consultants who regularly provide overheating assessments for developments across England and Wales.
We work closely with architects, developers, builders and homeowners to deliver clear advice and practical solutions that satisfy Building Control requirements.
What is Part O?
Part O is the section of the Building Regulations that aims to reduce the risk of overheating in new residential buildings.
What is TM59?
TM59 is the industry standard methodology published by CIBSE for assessing overheating in residential buildings using dynamic thermal modelling.
Is an overheating assessment always required?
No. It depends on the type of development, location and design. Your Building Control Body or SAP assessor will normally advise whether one is necessary.
Can you help if my property fails?
Yes. We can recommend design changes to improve performance and help achieve compliance.
How long does an overheating assessment take?
Most assessments can be completed within a few working days once all required drawings and project information have been received.
