In Massachusetts, the Bentley Arena is the first standalone ice arena to earn LEED Platinum. The arena uses technology that captures heat generated from the rink’s ice-making equipment to heat water throughout the building.
Other arenas have employed strategies to save energy and costs. A pond loop geothermal refrigeration system reduced operating costs at a Wisconsin arena,
Environmental Air-Flow Management System That Helps Produce Cleaner Water and Indoor Air – NHL’s LA Kings Staples Center Arena
Global sports and entertainment company AEG and its National Hockey League franchise the LA Kings are working with BluEco Technology Group on deploying efficient ice technology at Staples Center in Los Angeles.
Called BluEco Liquid Crystalline Turbex (LCT), the proprietary technology is a molecular level environmental airflow management system that produces pure water while cleaning indoor air and reducing energy costs for arena and facility operators and owners, the partners say.
“The formulated ice has fewer impurities and a clearer, harder, more dense surface,” AEG, the LA Kings, and BluEco said. “Additionally, the technology eliminates an arena’s reliance on the municipal water systems to create and maintain its ice sheet.” The standalone plug-and-play system doesn’t require integration with ducting or the replacement of existing systems, according to BluEco.
The system was piloted in Los Angeles at AEG’s Staples Center during the LA Kings’ recent season. As a result of that pilot, Staples Center saved hundreds of thousands of gallons of water over the course of the season and lowered its carbon footprint, the partners reported.
“By strategically and efficiently managing indoor air-flow, we no longer need to run air-conditioning at low temperatures to maintain quality ice, thereby delivering fans a better arena experience,” LA Kings COO Kelly Cheeseman said. “The BluEco LCT system is not only cheaper to run but makes our existing HVAC system more efficient and less energy consuming.”
Although the BluEco LCT System was developed for creating ice sheets in hockey venues, the partners say that there are broader applications of the technology large indoor public facilities that need energy-efficient water production such as data centers, warehouses, laboratories, cold storage facilities, and golf courses.

Cutting Water Use at Sechelt Arena Almost by Half
Water efficiency is coming to the Sunshine Coast Arena in Sechelt, along with a number of upgrades to the Gibsons and Sechelt arenas as mandated by provincial safety authorities.
Last fall ice installation at the Sunshine Coast Arena was delayed because of Stage 4 drought conditions. To prevent this from happening again, the Sunshine Coast Regional District (SCRD) will replace a condenser with a new one that uses a closed-loop cooling system, at a cost of $125,000, funded by capital reserves. The Gibsons arena already has a similar system in place. The change will be finalized at an upcoming board meeting.
“This change would have a significant impact on overall water consumption. Preliminary estimates suggest up to a 45 per cent reduction for water used for ice processes, meaning ice installation, cleaning and refrigeration over the course of a season,” said Ian Hall, general manager of planning and community development, at a May 10 committee.
Hall also pointed out that “drastically reduced” water demand with this new system will make it easier to consider other options, such as using non-potable sources, groundwater or rain-water capture. Staff are planning to conduct a feasibility study with ice user groups.
Meanwhile, other changes are coming to arenas on the Sunshine Coast.
In October 2017, an ammonia leak at a skating rink in Fernie, B.C. killed three men, in addition to triggering a seven-day state of emergency and the evacuation of 55 homes nearby the arena. The accident spurred authorities to assess rinks throughout B.C., including Sunshine Coast arenas.
As a result of those assessments, more than 60 mandatory upgrades have been issued to SCRD arenas by WorkSafe BC and Technical Safety BC, including adding new signs, updating procedures and installing or upgrading equipment.
More than 200 arenas have been assessed and at least two have been closed in the province, but it’s also put a strain on professionals qualified to implement the upgrades. “The market for refrigeration engineering and specialty trades is under an extreme load,” according to an SCRD staff report.
The SCRD arena upgrades are expected to cost between $150,000 and $330,000 and will be funded through existing capital and operating reserves. Hall said the ice installation dates for the fall are expected to remain the same, with Gibsons ice ready Aug. 20 and the Sechelt arena ice installed Sept. 23.

New Arena Named the Most Environmentally Sustainable in the Nation
First Standalone Ice Arena to Earn LEED Platinum — the Highest Possible Rating
The new, state-of-the-art multipurpose Bentley Arena is the most environmentally sustainable in the U.S. and the first standalone ice arena to earn the LEED platinum certification, the highest possible rating, according to the U.S. Green Building Council. The award for the recently opened, 76,000-square-foot arena highlights the building’s sustainable design and energy efficiency and Bentley University’s continued rise as an innovative, nationally-recognized business university.
“This first-in-the-nation rating for the Bentley Arena demonstrates Bentley’s strong and longstanding commitment to sustainability,” said Bentley University President Gloria Cordes Larson. “From our university-wide commitment to achieving carbon neutrality by 2030, to our Sustainability Sciencemajor for students, to our campus waste reduction program that recycles more than 270 tons of material per year, Bentley acts every day on our mission of preparing environmentally conscious, socially responsible leaders.”
“Thanks to the combination of the rooftop solar technology and energy-efficient mechanical design, the overall grid energy required to power the arena will be less than half of what it would take to power a building of a similar size,” said Amanda King, director of sustainability at Bentley. “These technologies also cut the building’s carbon footprint in half.”
The Bentley Arena hosts the university’s NCAA Division I hockey team and prominent university events such as career fairs, high-profile speakers, alumni events and concerts.
The standout sustainable features of the arena include:
- A 504 kilowatt, rooftop solar array developed by Rivermoor Energy that will generate 40 percent of the building’s annual electricity needs.
- Innovative technology that captures heat generated from the rink’s ice-making equipment to heat water throughout the building.
- More glass windows than a typical arena, allowing for more natural light that decreases the amount of electricity needed to light the building’s interior.
- High-efficiency LED lighting with smart, motion-detecting controls that turn off lights when no one is present to sharply reduce electricity usage.
- Ice-making and air conditioning systems that use zero CFC-based refrigerants. Chlorofluorocarbons or “CFCs” have been found to destroy the planet’s stratospheric ozone layer.
- The highest-efficiency plumbing fixtures on the market, including waterless urinals, dual-flush toilets, and low-flow faucets and showers to reduce the demand for water.
- At least 50% of wood used in the building is sourced from forests with certified sustainable forestry practices
- About 10% of construction and finish materials were locally sourced and about 20% of construction and finish materials contain recycled content.
