Train lab users to
use energy and
water saving
settings of water
systems.
Measurement and Verification
A well-constructed building only performs if it’s
operated and maintained properly. Proper
maintenance requires information; you can’t manage
what you don’t measure.
The LEED-NC rating system awards a separate
point (EA 5) for Measurement and Verification
(M&V). This includes installing power meters and
sub-meters to record consumption, logging data on
equipment operation (flows, temperatures, etc.) and
bringing the data together for analysis of conditions
and trends. An open BAS that readily integrates
different data sources and flexible reporting software
gives facility managers the tools to accomplish M&V
goals.
In a Green facility, M&V may also include meters for
site-generated power, and flow meters on alternative
water sources. Figure 2 through Figure 5 are varied
example
s of consumption reports, atmospheric
emission reports, fume hood usage reports and
other monitoring tools. Managers in Green facilities
need a unified set of tools to pull disparate
information together and evaluate sustainability.
