WAC 194-50-090

9.1.1 Requirements.Buildings implementing energy efficiency measures (EEMs) shall comply with the requirements of Section 9.1.1.1. All buildings shall implement an energy management plan as described in Section 5. The energy management plan shall be integrated into the building's capital management plan as described in Section 5. The energy management plan shall include the elements listed in Section 5.

9.1.1.1Implementation of energy efficiency measures.Energy efficiency measures (EEMs) identified from the energy audit shall be implemented in order to meet the building'sperformance target. Develop a written plan for maintaining the building's energy performance once the performance target has been met.

1. Space heating electrification:Buildings complying through Section 4.3.5 Space heating electrification are not required to perform an energy audit.

2. Grouped buildings EEMs: Except for buildings complying through Section 4.3.3 Investment criteria, implementation of EEMs to non-Tier 1 covered buildings complying at the grouped buildings level is acceptable, provided the energy audit demonstrates the energy savings from the EEMs implemented at the grouped buildings level will result in a WNEUI which meets the performance target of the grouped buildings.

3. Tier 2 covered buildings:Tier 2 covered buildings.

4. District energy system EEMs: Implementation of EEMs to district energy system(s) in lieu of or in combination with EEMs implemented directly to campus buildings is acceptable, provided the energy audit demonstrates the energy savings from the district energy system EEMs will be equal to or greater than the energy saved from the EEMs identified for the buildings. Energy savings shall be measured as a reduction in Btu per year.

9.1.2.1 Training of building staff. An ongoing written training plan shall be implemented. Building occupants and staff shall be trained, at a minimum, as established by the operations and maintenance (O&M) program defined in Section 6.

9.1.2.2 Multiple buildings. A multiple-building plan shall be implemented to coordinate EEM implementation and measurement of the EUI among buildings when complying at the campus, campus-level or connected building level.

9.1.2.3 Implementation and commissioning of EEMs.EEMs shall be implemented and commissioned in accordance with the Washington State Energy Code. Washington State Energy Code (WSEC) exceptions based on mechanical system or service water heating capacity shall not be applied when developing the scope for commissioning. For example, the 2018 WSEC, Section C408.1 General, the exceptions do not apply. The qualified energy auditor or qualified person shall review the commissioning report and certify that the EEMs are functioning as intended.

Informative Note: For guidance on commissioning protocols, refer to ASHRAE Guideline 0.2-2015 Commissioning Process for Existing Systems and Assemblies and ASHRAE Guideline 1.2-2019 Technical Requirements for the Commissioning Process for Existing HVAC&R Systems and Assemblies.

9.1.2.4 Energy efficiency sequencing. Implementation of EEMs shall be prioritized to take advantage of the life cycle of building systems and to minimize the disruption of building occupants. Delayed implementation shall be evaluated using the methodology included in Normative Annex X and reported in the energy management plan.

9.2.1 Verification of implemented EEMs - Meeting the EUIt. Upon implementation and commissioning of EEMs for buildings complying through Section 4.3.2.1 Building does not meet the energy use intensity target (EUIt), the building's EUI shall be monitored until one full year's data demonstrates that the WNEUI is less than or equal to its EUIt.

9.2.2 Verification of implemented EEMs - Investment criteria. Upon implementation and commissioning of EEMs, for buildings complying through Section 4.3.3 Investment criteria, the building's energy consumption shall be monitored until one full year's energy savings, as measured after implementation, meets or exceeds 75 percent of the optimized bundle projected energy savings, aligning with the energy audit report. Or, if all identified EEMs with simple payback are implemented, the energy savings, as measured after EEM implementation, shall meet or exceed 75 percent of the energy savings projected in the energy audit. The qualified energy auditor or qualified person shall review the results of the energy monitoring and certify that the energy savings meets or exceeds 75 percent of the energy savings projected in the optimized bundle or in the energy audit, as required.

9.2.3 Verification of implemented EEMs - Minimum energy use reduction. Upon implementation and commissioning of EEMs for buildings complying through Section 4.3.4 Minimum energy use reduction, the building'sEUI shall be monitored until one full year's data demonstrates the WNEUI is a minimum of 15 percent below the baseline WNEUI.

9.2.4 Verification of implemented EEMs - Space heating electrification. Upon implementation and commissioning of the electric heat pump equipment replacing the fossil fuel consuming space conditioning equipment for buildings complying through Section 4.3.5 Space heating electrification, the qualified person shall provide verification using Form E - Space Heating Electrification Report, in accordance with Section Z4.8.

9.3 Compliance. The qualified person shall complete the compliance documentation as required in Normative Annex Z.
