ii. Assess existing condition and operational procedures of the
building and major building systems and identify areas for
improvement.

iii. Establish operational performance goals for energy, water,
material use and recycling, and IEQ, and ensure incorpora-
tion of these goals throughout the remaining life cycle of the
building.

iv. Incorporate a building management plan to ensure that oper-
ating decisions and tenant education are carried out with
regard to integrated, sustainable building operations and
maintenance.

v. Augment building operations and maintenance as needed
using occupant feedback on work space satisfaction.

b. Commissioning . Employ recommissioning, tailored to the size and
complexity of the building and its system components, in order
to optimise and verify performance of fundamental building
systems. Commissioning must be performed by an experienced
commissioning provider. When building commissioning has
been performed, the commissioning report, summary of actions
taken and schedule for recommissioning must be documented.
Building recommissioning must have been performed within
four years prior to reporting a building as meeting the guiding
principles.

2. Optimise Energy Performance

a. Energy efficiency. . Three options can be used to measure energy
efficiency performance:

i. Option 1: Receive an ENERGY STAR ® rating of 75 or higher
or an equivalent Labs21 Benchmarking Tool score for labora-
tory buildings.

ii. Option 2: Reduce measured building energy use by 20%
compared to building energy use in 2003 or a year thereafter
with quality energy use data.

iii. Option 3: Reduce energy use by 20% compared to the ASHRAE

90.1-2007 baseline building design if design information is
available. Use ENERGY STAR and FEMP-designated energy-
efficient products, where available.

b. On-site renewable energy . Per E.O. 13423, implement renewable
energy generation projects on agency property for agency use,
when life cycle is cost-effective.

c. Measurement and verification. . Per the Energy Policy Act of 2005
Section 103, install building level electricity meters to track and
