plan as specified in Normative Annex L.
3. Implementation documentation as specified
in L2.2.5 Documentation.
5.1.3 The EM shall provide

annually.
5.2.1 Provide measured
net energy use data for each
covered
building, including all forms of imported and exported energy from at
least 12 consecutive months of data monitored in a period not to exceed two
years prior to the efficiency audit. The net energy concept is illustrated in
Figure 5-1, Table 5-1, Table 5-2 and is calculated in accordance with Section
5.2.4 as follows:
Building net energy use = (1a + 1b + 1c + 1d)
- (3a + 3b + 3c + 3d +3e)
Where 1a, 1b, 1c, and 1d are metered energy supplies that are
used in the building (this includes bulk energy sources), and
3a, 3b, 3c, 3d, and 3e are metered energy excesses that are supplied to another
building or grid as useful energy.

End
use deductions. Where submetered from a
building's
meter, the following end use energy consumption may be deducted from the
building's measured
net energy use:
1. Electric vehicle charging equipment that
transfers electricity to batteries or other energy storage devices in electric
vehicles.
2. Electric loads related
to broadcast antennas, on-site cell phone towers or other communications
equipment that is unrelated to the primary purpose of the
building.
3. The
AHJ may add additional end use deductions based on
technological advancements.
5.2.1.2
Connected buildings.
Where energy use is not monitored at the
covered building
level:
1.
Tier 1 covered
buildings: Net energy use data may be provided at the
connected building level.
2.
Tier 2 covered buildings:
Net energy use data shall be provided at the connected
building level.
5.2.1.3
Campuses.
Campuses with
district energy systems use the
campus net energy use outlined in Table 5-2. Provide measured
net energy use data for the
campus including
all forms of imported and exported energy from at least 12 consecutive months
of data monitored in a period not to exceed two years prior to the efficiency
audit. Provide measured energy on the input side of the
district energy
system and include
net energy use data for each
covered building. Campus net energy use is calculated as
follows:
Campus net energy use = (1a + 1b + 1c + 2a +
2b + 2c) - (4a + 4b + 4c + 4d + 4e)

campus. Thermal energy for the campus shall
be measured at the input side of the district energy system.
5.2.2 Energy use data
for each type of energy imported into and exported from the
building shall be collected from utility or energy delivery
bills (that must include the quantity of energy or fuel delivered) or by
monitoring local energy meters (either utility or owner-provided meters).
Owner-provided energy meters shall meet the metering accuracy, tolerances and
testing requirements of Title 480 WAC or WAC
51-11C-40904 (Section C409.4 of
the
WSEC).
