To reduce operational energy consumption and associated carbon emissions by installing appropriate controls to reduce unnecessary energy consumption (waste).
- Are there internal temperature controllers in individual rooms or zones?
- Can the output from the heat generator and cooling generator be modulated?
- Does the system have an interlock control?
- Can the air flow be controlled at room level?
- Is the supply air temperature controlled?
- Is the air humidity controlled?

|-||The evidence below is not exhaustive, please also refer to the ‘BREEAM evidential requirements’ section in the scope of the Guidance for appropriate evidence types which can be used to demonstrate compliance.|
|All||Visual inspection and verification through photographic evidence of controls.|
|All||All remote control must be via an accessible device.|
|All||Extract of relevant O&M manuals or copy of manufacturer information.|
These include separate or integrated controls associated with individual building servicing systems and appliances as well as building management system (BMS) and remote-control devices e.g., via a smartphone app.
This control prevents the heating system operating when the cooling system is operating and vice versa.
Devices are accessible if they link with a web or mobile interface that meet the WCAG2.0 (ISO/IEC 40500) accessibility standards (www.w3.org;www.iso.org).
Where the above is not met, (e.g. only a visual display unit is installed), a device must have been installed that meets an equivalent level of accessibility to ensure it is usable by people with disabilities.
