Overview of Overheating Studies
Thermal Comfort Analysis
Overall occupancy comfort must be demonstrated for the purposes of planning BREEAM or retrospective reasons.
Overheating analysis is carried out using dynamic simulation sotware IES, which gives the opportunity to look at real situations on an hourly basis for a selected period of time.
How is this measured?
Depending upon the project type (schools, offices, homes, etc.) this will determine the official criteria to be analysed against. These are set as per CIBSE guidance:
- TM52 - The limits of thermal comfort: avoiding overheating in European Buildings
- TM59 - Design methodology for the assessment of overheating risk in homes
- BB101 - Ventilation, thermal comfort and indoor air quality in schools
Internal temperatures are assigned on the zonal level by using the 'Building Template Manager' option in the IES software. Internal heat gains is an important element for overheating analysis.
Another important aspect is building construction, specifically the fabric make-up and U-values, glazing U-values and g-values. Thus informing the design team on building performance and important shading options such as brise soleil.
All data is checked against the relevant weather file set under TM49.
