Proposed Motion: |
Move City Council approve Agreement No. FF3-910-4540, with kilowatt Engineering, Inc., dba kW Engineering, Inc., for the City Facility Energy Audit, in the amount of $121,985. |
Background/Discussion: |
The Buildings and Facilities Division proposes to conduct an energy audit to specifically focus on building mechanical systems and their controls. On average, 40% of energy costs in commercial buildings are attributed to heating, ventilation, and cooling systems.The audit would be applied to the City’s buildings with the highest electrical usage. These facilities include Chandler City Hall, Police Department Downtown Station, Chandler Municipal Court, Tumbleweed Recreation Center, Public Works & Development Services, Information Technology, and Downtown Library. The audit will be performed in two phases: 1. Investigation Phase: Perform an American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Level 2 Energy Audit that conforms to the lastest ASHRAE 211 Standard, including but not limited to:
- Perform energy survey to verify existing systems sequences and baseline operational behavior.
- Deploy a building analytics system.This step, a 6-8 week process, will occur concurrently with the Investigation phase and carry through the Implementation and Monitoring phase. This system will interface with the existing building management system and be used to identify, support, and validate suggested conservation measures and commissioning.
- Propose energy conservation measures inclusive of savings and estimated implementation cost (including anticipated return on investment). Implementation of low or no cost opportunities, obtained through the building analytics system, will begin during Q2 CY 2023. Capital improvement cost measures, based on investigation findings, identified in Q3 CY 2023.
- Produce investigation report aggregating the information detailed above estimated Q3 CY 2023.
The Investigation Phase is anticipated to be complete in Q2-Q3 of calendar year (CY) 2023.
2. Implementation and Monitoring Phase will support the City with implementation and construction of selected energy conservation measures: The scope of work includes an ongoing process of evaluation, implementation, and monitoring changes for desired savings and operational effectiveness, including:
- Develop initial scopes of work for the City to seek contractor quotes.
- Develop updated sequence of operations to be provided to controls contractor for implementation.
- Provide services to verify the proper installation and implementation of contracted activities.
The Implementation and Monitoring Phase is anticipated to occur between Q3 of CY 2023 and Q2 of CY 2024.
