BREEAM Thermal comfort
 Aim and benefits
To make sure buildings users are warm enough in the winter, cool enough in the summer, and can have control over their own heating.
- Is your building cool enough in the summer and warm enough in the winter?
- In the future with climate change, will your building still be thermally comfortable?
- Have you got thermal zones and controls so building users can control their own thermal comfort?
 When to consider
See Step-by-step guidance below for some guidance on actions in relation to the RIBA stages.
 Step-by-step guidance
Is your building mechanically ventilated? If yes, you’ll probably achieve the credits.
There’s no excuse in this day and age for not achieving the 3rd credit. Note, in a school situation, it might only be that FM can control the heating/cooling so that kids don’t keep changing TRVs (thermostatic radiator valves) etc. In retail buildings/prisons etc the credit only refers to staff controlling the temperature.
- The type of people that will use the building.
- How capable they will be at using the different types of equipment.
- How often they will be using the spaces and what the spaces will be used for.
- How do individuals want to interact with heating/cooling controls?
- How can you balance different peoples’ requirements?
- How will the systems interact with each other?
- Does there need to be an override so systems are not used inefficiently?
If you are working for an M&E subcontractor you may need to produce a markup of an as-built drawing showing zones and controls. You may also have to confirm formally that there have been no changes to the design which would affect the overheating risk, or make the building too cold in the winter.

 Tips and best practice
Don't forget winter time thermal comfort.
TM52 is not a limiting stop. A building will not necessarily be comfortable because it meets TM52. Try not to let the thermal zoning exercise feel like “something you just have to do for BREEAM” – control strategies are a really important part of soft landings and trying to reduce the performance gap

 Applicable Schemes
The guidelines collated in this issue support document aim to support sustainable best practice in the topic described. This issue may apply in multiple BREEAM schemes covering different stages in the life of a building, different building types and different year versions. Some content may be generic but scheme nuances should also be taken into account. Refer to the comments below and related articles to understand these nuances.
