REDIT REQUIREMENT
1 credit for installation of devices to monitor water leakage within the
fresh water distribution system.
A
SSESSMENT
The Client shall submit a report detailing any system for monitoring water
leaks within internal plumbing installations.
The assessment will seek to establish if mechanisms are in place that
effectively limit wastage of water by the application of water saving
devices. The provision of devices for monitoring consumption for each of
the major water using sectors shall be identified.
Various approaches are available and BEAM is not intended to be
prescriptive as to which should be used.
B
ACKGROUND
The provision of automatic shut-off devices, particularly in public use
areas, can save significant amounts of water. Examples of automatic
shut-off devices are spring-loaded taps, electronic proximity sensors,
etc., but excluding timed shut-off devices.
Generally in Hong Kong buildings there is very limited provision for
monitoring water use other than the meters required for utility billing
purposes. The provision of measurement devices for major water uses
can assist facility managers to audit water use and can encourage the
introduction of water saving measures.
