To reduce the level of greenhouse gas emissions related to the leakage of refrigerants.
Is there an automated refrigerant leak detection system in place for all equipment that uses refrigerants?
|Credits||Answer||Select a single answer|
|0||A||Question not answered|
|0||B||No leak detection system in place|
|3||C||Yes, warning alarm or lighting only|
|4||D||Yes, warning alarm or lighting, automatic shutdown and pump down of refrigerants|
|4||E||Only environmentally benign refrigerants (GWP ≤1, or solid-state) are used|
|Criterion||Assessment criteria||Applicable answer|
Where no refrigerants are used or only small (refrigerant charge in each system is ≤5kg) hermetic systems are installed in the asset, this issue can be filtered out of the assessment.
|2||This issue only applies to refrigerants used in equipment that is installed in the building, mainly for comfort cooling and heating (e.g. heat pumps).||C-E|
|3||A list of typical refrigerants with a low GWP can be found in Table 24: Common refrigerant types with a low GWP in the Checklist and Tables section of issue Pol 04 Global warming potential of refrigerants.||C-E|
|-||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||Operation and maintenance manuals detailing installation of leak detection systems, or site inspection.|
|All||In case of environmentally benign refrigerants, manufacturer’s confirmation of either minimal risk of leaks or minimal impact of leaks.|
|1||Statement from the building manager indicating that the asset does not contain any systems that contain refrigerants or confirmation that the total charge is ≤5kg in any systems that are present.|
