The Ice Rink Keeps the Pool Warm at the Strathcona Gardens Recreation Centre in Campbell River.

Strathcona Regional District installed an ‘energy recovery loop’ which channels waste energy from the ice rink’s compressor room to heating the Centre’s pools.

Project Summary

The Strathcona Gardens Recreation Centre is a local government operated multi-purpose recreation facility that includes two ice arenas, swimming and leisure pools and a variety of other fitness and recreational components. It is located in the City of Campbell River – in the Strathcona Regional District (SRD) on Vancouver Island.

In 2014 the SRD took climate action at the building level by installing an energy recovery system at their recreation centre. The system consists of a six inch pipe full of glycol that runs in a continuous loop from the arena condensing tower to the heat pumps located near the recreation centre pools and back to the arena. Because of the circular route of the energy recovery system it is often simply called ‘the energy loop’.

The energy loop channels waste heat from the arena ammonia compressor room, where ice is made for the two rinks, to the swimming and leisure pools. It uses 600 feet of pipe. Energy is added to the loop at the compressor room and removed as needed to heat the pools.

“The whole system is really a very simple concept of absorbing waste heat or energy from one location and bringing it to an area where there is a demand” explains Lorne Parker, the Operations Manager of the Strathcona Gardens Recreation Complex. “In the recreation centre we are constantly cooling one area of our building while heating another.”

Parker initiated the retrofit by researching the system and by exploring funding opportunities. He received full support from the Strathcona Gardens Commission. The Commission oversees the operation of Strathcona Gardens Recreation Centre and consists of representatives from the City of Campbell River and Strathcona Regional District Electoral Area D.

The Strathcona Gardens Commission approved and awarded construction of the energy loop to a Victoria company in August 2013. The construction was completed March 13, 2014.The energy loop is designed and sized in a way that will enable future expansions to connect to the current infrastructure at a significantly lower cost. Future expansions or connections to the energy loop could include air handling units, preheating domestic water and snow melting pits for the ice cleaning machines.

Energy Savings/GHG reductions

The energy saved by the participating local governments as a result of this project will be between 11,000 and 13,000 gigajoules of natural gas energy every year. This will be a 561,000 and 663,000 kg of CO2 reduction in CO2 produced. These savings will significantly reduce the natural gas bill and will also reduce the carbon footprint of the recreation complex.

“Investment in high efficiency heating systems like Strathcona Gardens is helping to reduce the carbon footprint from local government operations.” – Rhona Martin, UBCM President

Business case

The total project cost was $310,000 with $99,750 coming from a grant and the remainder funded by the Strathcona Regional District. The grant money was supplied by the Gas Tax Fund (Gas Tax Innovations Fund) – managed by the Union of British Columbia Municipalities (UBCM).

“Investment in high efficiency heating systems like Strathcona Gardens is helping to reduce the carbon footprint from local government operations. We are appreciative of the support provided by the Federal government for this project,” said Rhona Martin UBCM President

The reduction of natural gas used to heat the main and leisure pools will save the local government $50,000-$60,000 annually.

Co-Benefits

Increased community awareness about climate action solutions are an additional benefit of the energy loop system. The innovative system serves as a public education tool about waste-heat recovery and informs staff about building energy reduction.

Complementary education such as building operator training helps staff identify other energy-reduction and maintenance measures to save energy in the same building. Subsequently, staff has also replaced arena lighting with energy efficient fixtures and are participating in a anti-idling campaign.

The entire project shows the commitment of the Strathcona Regional District and its citizens to reducing greenhouse gases.

Lessons learned

Strathcona Gardens Recreation Complex Operations Manager Lorne Parker encourages other local governments to consider this type of climate action tool and to tour other facilities that have undertaken similar types of projects. Research is a key component for successful projects. Parker has learned the importance of early preparation when applying for grant money, “I try to have my projects and RFP’s shelf-ready, so that when there is opportunity you can take full advantage.”

In 2015, the City of Kimberley BC began commercial operation of SunMine, the province’s first municipally-owned utility-scale solar facility.

SunMine is the first solar project in the province to sell power directly to the grid through BC Hydro’s Net Metering program. The project has allowed the community to utilize the Sullivan mine’s now fully reclaimed brownfields and make use of existing transmission infrastructure that once served the mine.

Project Summary

The City of Kimberley’s SunMine is one of the largest solar projects in British Columbia and the first municipally-owned utility-scale solar facility. The facility was completed in 2015 and started commercial operation on June 22nd of that year producing enough to power about 250 homes at peak production. The location chosen for the project contained brownfields that have been fully reclaimed by Teck and donated for the the SunMine project along with the existing infrastructure. This site presented few opportunities for any productive, tax-generating use but now includes 96 sun-tracking solar masts, each with 42 solar modules for a grand total of 4,032 modules.

The new mine provides an opportunity to assess the technology. It is the first solar project in Western Canada to utilize tracking technology, allowing the facility to increase energy production earlier and later in the day. Trackers also help align the panels to season shifts in the height of the sun above the horizon.

So far, the solar project is collecting 40% more energy than traditional, fixed solar projects. It is expected that these results will encourage the development of other solar projects around the province. The City is currently seeking partners to expand the project to the point where it is capable of producing 15 Megawatts. Kimberley’s Mayor, Don McCormick, claims that the site has the potential to reach 200 Megawatts. This infographic illustrates how the SunMine facility works.

Energy Savings/GHG reductions

At the current capacity, SunMine can power about 250 homes. Over the first 2.5 years of production (up to end of December 2017), the SunMine generated 4419 MWh, or 89.6% of anticipated energy production. Monitoring software records show that the project helped the city avoid 2.5 tonnes of NOx, 1770.8 tonnes of CO2, and 6.4 tonnes of SO2 over the same period (as estimated using US national energy generation and emissions factors).
Business Case
This project makes use of fully reclaimed brownfields and existing infrastructure from the operations of the old Sullivan mine. It provides a new tax base for the City in an area with limited options for use.

SunMine’s $5.35 million facility cost was covered through various funding mechanisms that include: $1M Provincial Innovative Clean Energy (ICE) grant, $2M financial contribution as well as land and infrastructure donation from Teck, the company which formerly operated the Sulivan mine, $300,000 donation by the Columbia Basin Trust, and $50,000 provided by the Southern Interior Development Initiative Trust. After citizens of the Kimberley voted 76% in favour in referendum, a final $2 million was borrowed by the city to support the project that will be repaid with the revenue from the sale of renewable energy to BC Hydro.

The SunMine makes use of BC Hydro’s Net Metering program, which enables electricity to be added the grid when facility generates more than the current need and credits to be redeemed when the need exceeds the supply. The facility currently produces enough electricity at the peak production to power about 250 homes and the electricity is sold to the BC Hydro grid made possible through Net Metering program.

Kimberley residents believe that there is now sufficient evidence that the technology works and has begun seeking investors to expand the project to point where SunMine is producing up to 15 megawatts or more.

Co-Benefits

Economic

The project has increased the town’s visibility which has been credited with improving tourism in the area.

Educating the Public about Green Energy

Since opening, over 1,000 people have toured the facility, including students from the local elementary, middle, and high schools, as well as College of the Rockies and Selkirk College. In addition, over 200 articles written have been written about the project, and over 14,000 unique visitors have browsed the website.

Support for Innovative Green Energy Technologies

The SunMine project was the first project in Western Canada to utilize tracking technology. The engineering and project experience is expected to garner the region a competitive edge for future initiatives in the growing renewable energy market.

Lessons learned

Consult Experts Early

Engaging the right experts early would have helped the City get the specifications defined early in the project and save time and money in the long run. The original estimate was “a twoonie a watt” and turned out to be a “fiver”.

Have a Healthy Contingency

An project that is the “first of it’s kind” should have a contingency for unexpected complications. For SunMine, it turned out that there was a delay when spare parts needed to be ordered. If there had been a contingency, a small inventory of spare parts would have been readily on hand.
