5.1.2.14 Operations and Maintenance Plan including:

1. An operations and maintenance ( O&M ) program as defined in Section 6.

2. An O&M implementation plan as specified in Normative Annex L.

3. Implementation documentation as specified in L2.2.5 Documentation.

5.1.3 The EM shall provide access to the energy management plan to the building occupants 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.

5.2.1.1 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)

ast 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:

5.2.1.4 Decarbonization plan . Participating campuses' net energy use data shall include all buildings on the 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 ).
