Arenas Heat Recovery and Dehumidification Project Update

The following are key points for consideration with respect to this report:

1. CCAM and Facilities Staff completed an Arenas Net Zero Study in 2021 to review the feasibility and projected paths for the Town arenas facilities to meet net zero objectives by the year 2030. The study proposed a phased approach of capital project developments in the arenas that built on the current projected ten (10) year capital forecast for the arenas and the need for “end of life“ capital replacements of major dehumidification and HVAC equipment replacements. The study did not identify specific requirements for electrical infrastructure upgrades including transformers as it was considered outside of the study scope. The study scope was intended to result in a conceptual level technical solution to reduce greenhouse gas emissions including an outline of potential measures and lifecycle financial analysis for each measure.
2. The heat recovery and dehumidification replacement projects for the two arenas had a combined budget of $3,042,000 for the projects inclusive of construction, design and engineering, and project management costs. The Class C estimated budget for the heat recovery and dehumidification projects, including additional electrical infrastructure upgrades is now estimated at $4,829,084. The combined capital projects have $3,042,000 in approved funding and $1,018,860 in additional available funds for a total of $4,060,860. This is a projected shortfall of $768,224 in available funding.
3. The current construction environment has many unknown risks and challenges at this juncture. Chief among these now is cost escalations and supply chain issues with major pieces of HVAC equipment. Preliminary market reviews completed through our consultants indicate that the dehumidifiers have a much longer lead time for procurement than in the past. We are told to expect a lead time of 30 to 34 weeks for delivery of this equipment from the time of initial order. Staff are attempting to ensure timely acquisition of equipment by procuring these major pieces of equipment in advance of engaging a general contractor for completion of this project.
4. Design and engineering for replacement of the major HVAC components of the arenas with systems relying on a combination heat recovery and electric supply to replace existing natural gas supply will require an upgrade to electrical supply systems at the arenas. At the AACC the arenas will require an upgrade to a 750/1000 KW transformer system. The process for ordering a new transformer and replacing this service is estimated to be approximately 10-12 months and would need to be initiated in 2022 to be ready for 2023 and the anticipated final completion of the heat recovery and dehumidifier installs at the AACC. The MMSP had a new transformer added during the 2013 expansion and has sufficient supply to the facility to accommodate all future measures for HVAC replacements as per the Net Zero Study, however the supply will need additional infrastructure to the Alcott/Fernbrook side of the facility.
5. Efficiency Engineering Inc. have been engaged to complete the design and engineering for the heat recovery and dehumidification projects for the AACC and MMSP. Additional scopes of construction work at both arenas are required to complete the projects. An additional scope of design and engineering work is required for both projects. Efficiency Engineering have
   proposed an additional set of fees to complete this work. In the interest of project integration and continuity, it is proposed to extend the additional works to Efficiency Engineering at the proposed fees.
6. Consultant cost estimates to date have been Class C estimates. The current market for procuring equipment and services has been described as challenging and uncertain with regards to cost escalations and availability. Scheduling and cost estimates could be further impacted by additional variables impacting the current projections negatively.

• This report impacts and/or helps address climate change and the Town’s Net Zero target through corporate energy savings.
• The implementation of these projects in the arenas as recommended by the Net Zero Arenas study is critical to ensuring alignment with the town’s target of net zero carbon emissions by 2030.
• It is expected that as a result of the implementation the town would avoid 203.7 tCO2e on annual basis which is 21.7% reduction below the 2019 level of 940.4 tCO2e of annual carbon emissions for both AACC and MMSP.
