Assessment criteria

Criterion	Assessment criteria	Applicable answer
1	User controls that allow independent adjustment of heating, cooling or ventilation within the asset are required in the following spaces: Owned spaces: small rooms for one or two people, e.g. cellular offices, consulting room. Shared spaces: multi-occupied areas, e.g. open-plan offices, workshops, hospital ward. Temporarily owned spaces: where occupants expect to operate the controls while they are there, e.g. meeting rooms, hotel bedrooms, school classroom.	C,D
2	User controls which allow independent adjustment of heating, cooling or ventilation within the asset are not required in the following areas: Occasionally visited spaces: where users generally stay for a relatively short period each time they visit, e.g. storerooms, shelving areas in libraries, aisles of warehouses, toilets, plant room. Unowned spaces: where areas are expected to be heated but the controls are not operated by the users, e.g. circulation areas. Managed spaces: where someone is responsible for controlling the heating, cooling or ventilation and individual users do not expect to have control, e.g. atria, cinemas, concourses, entrance halls, lecture theatres, libraries, restaurants, shops, sports halls and theatres. Spaces that require controlled environmental conditions for reasons other than user comfort, e.g. industrial operational and storage areas, laboratories, museum display areas.	C,D
3	Compliant forms of temperature control include, but are not limited to: Room thermostats Thermostatic radiator valves (TRVs) Openable windows, doors or roof lights Ceiling fans Fan coil units with user control Building Management System controlled set points with local override controls limited to a set range. Where openable windows, doors or roof lights are provided, these can only be used as a compliant form of control for either temperature or ventilation, not both. To achieve both sets of credits, a different form of temperature or ventilation control must also be provided.	C
4	Compliant forms of ventilation control include, but are not limited to: Openable windows, doors or roof lights Trickle ventilators Ventilation fans with user control (including fan coil units with ventilation control) Building Management System controlled set points with local override controls limited to a set range. Where openable windows, doors or roof lights are provided, these can only be used as a compliant form of control for either temperature or ventilation, not both. To achieve both sets of credits, a different form of temperature or ventilation control must also be provided.	D
5	Portable equipment, e.g. electric desk fans or fan heaters, do not comply with the criteria.	C,D
6	User controls must be located in the vicinity of the zone or space they control and be easily accessible to users of the space.	C,D
