ASHRAE Standard 100, 2018Section 5Energy management plan.

WAC 194-50-050
Exception to 5.1.1 - Not adopted.
5.1.2.1 Energy accounting in accordance with Section 5.2.
5.1.2.2 In the initial year of compliance, the building's weather normalized energy use intensity (WNEUI) and energy use intensity (EUI).
5.1.2.3 Annual updates of the net energy use, WNEUI and EUI.
5.1.2.4 Annual comparison of the net WNEUI and EUI to the EUIt.
5.1.2.5 Documentation of original, current, and changes in number of occupants, weekly operating hours, or time of day scheduled for occupancy, production rates, and energy using equipment that would have caused change in the measured WNEUI and EUI.
Exceptions to 5.1.2.12:
1. Buildings and grouped buildings that meet the EUIt.
2. Buildings that have implemented a utility program lighting upgrade covering 75 percent of the building's GFA, within the previous five years, can use the lighting schedule provided by the utility program.
3. Tier 2 covered buildings.
4. Buildings not meeting the definition of covered building.
5.1.2.13 The current lighting satisfaction survey and lighting checklist as described in Appendix D of Performance Measurement Protocols for Commercial Buildings1 or as approved by the AHJ.
Exceptions to 5.1.2.13:
1. Buildings and grouped buildings that meet the EUIt.
2. Buildings that have implemented a utility program lighting upgrade covering 75 percent of the building's GFA through a utility program within the previous five years.
3. Tier 2 covered buildings.
4. Buildings not meeting the definition of covered building.
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 energyuse data for each covered building, including all forms of imported and exported energy. Energy generated and used from renewable on-site energy systems does not need to be included. The data shall be from at least 12 consecutive months of data monitored in a period not to exceed two years prior to the compliance date. 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.

5.2.1.1End 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 where energy use does not support building functions.
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)
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). Upon the written authorization or secure electronic authorization of a building owner or operator, a utility shall either upload the energy consumption data or provide consumption data in an electronic document formatted for direct upload to Energy Star portfolio manager. For any covered building with tenants, an electric or gas utility must, upon request of the building owner, provide the building owner with the energy consumption data or aggregated monthly energy consumption data without requiring prior consent from tenants. For more information, see RCW 19.27A.170. 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).
5.2.3 Energy conversion factors. The site energy content of different forms of purchased energy shall be converted from the purchased unit to the standard site energy unit using the conversion factors incorporated in Energy Star portfolio manager.
5.2.4 The energy accounting system shall be Energy Star Portfolio Manager as specified in Normative Annex Z.
