Measurement and Verification (3 Points)
LEED credits are awarded if the project team can demonstrate that energy and
water consumption over time have been accounted for. This involves metering
systems and management tools such as an energy management application
that can track actual usage and cost, configure “what-if” scenarios, compare
projected cost with actual costs, diagnose faults and failures, and so forth.
Such an application can be standalone or part of a portfolio of facility
management applications and should be considered a standard component
needed to manage a smart building.
The framework for measurement and verification is the International
Performance Measurement and Verification Protocol (IPMVP). IPMVP is a
guidance document that addresses determining and documenting savings
resulting from energy-efficiency projects. It provides a framework and four
measurement and verification (M&V) options for how savings can be trans-
parently, reliably and consistently determined in a manner that enables inde-
pendent verification. These options include a partially measured retrofit, a
building retrofit, and whole-facility and calibrated simulation, where energy
systems are characterized through simulation or engineering analysis. LEED
does not confine the use of IPMVP M&V to energy systems.
OUTDOORAIR–DELIVERYMONITORING(1 POINT)
LEED credit is given for a monitoring system that can provide data on the
ventilation of spaces that can be used to adjust the HVAC system. The result
is improved indoor air quality and occupant comfort. Such a system will mon-
itor air flow and carbon dioxide (CO 2 ) levels. The monitoring sensors can be
designed based on activity levels and zones or space use, then integrated in
the building automation system, thus becoming part of a smart building.
The system is required to generate an alarm when the HVAC system varies
more than 10% from its designed performance.
CONTROLLABILITY OFSYSTEMS—LIGHTING
ANDTHERMALCOMFORT(1 POINT)
LEED credit is provided when the building affords individual occupants or
specific groups in multioccupant spaces (conference rooms, classrooms, etc.)
the capability of controlling the lighting, temperature, and ventilation of their
