Ice rinks across North America are the social and cultural hubs of their communities. There are approximately 4,800 indoor ice rinks in North America with an average age over 30 years. More than any other time in history, techniques and technologies exist to improve arena operations while lowering our game's environmental impact, helping to keep the doors open and the ice hard and fast for future generations of hockey players.

The techniques and technologies reshaping the ways we think about rink efficiency.

Perhaps more than any other sport, hockey is connected to the natural environment. We rely on freshwater to make our ice, energy to fuel our operations and healthy communities for our athletes, employees and fans to live, work and play. We also rely on cold climates to continue the tradition of outdoor hockey, a critical component of the game’s history and culture. Through the NHL Greener Rinks Initiative, we invite all hockey arenas to join us in our mission to track and improve the environmental impact of the greater hockey community.

For years, rink operators manually assessed data – from the performance of equipment, to the building’s event schedule and the weather outside – to create a suitable indoor environment. Today, technology is available to help rink operators manage and control their facility for greater efficiency.

SOLUTION: DEHUMIDIFICATION

Energy supply costs generally make up about 75% to 80% of an arena’s utility bill. Arena operators should consider strategies to manage and reduce electricity and gas consumption.

GAME LIGHTING

Back to Overview

Ice rinks use a variety of operating systems – from the refrigeration equipment that freezes the ice, to the heating equipment that warms water for showers and ice making. Ice rinks purchase energy to provide all of these needs separately, wasting otherwise re-usable energy from the refrigeration system.

SOLUTION: BUILDING LIGHTING

Refrigerants are critical substances used to create and maintain an ice sheet. Today, great care is demanded for the use of synthetic refrigerants, which have the potential to deplete the ozone and contribute to global warming. Specifically, the United States and Canada are phasing out the production and import of hydrochlorofluorocarbons (HCFCs) in order to protect the stratospheric ozone layer. This decision has an effect on the future of ice rink refrigeration.

REFRIGERANTS

Adequately insulated walls and ceiling makes it possible to control the indoor climate regardless of the outdoor climate. The main function of an ice rink envelope is air tightness and thermal insulation.

Primary Efficiency Measures

Solar photovoltaic systems generate electricity from sunlight and can provide a portion of renewable electricity for a facility at a predictable rate. Fuel cells are devices that convert fuel (such as biogas or natural gas) into electricity through an electro-chemical process (rather than combustion), creating cleaner, quiet electricity directly on site. Smart energy storage systems learn your facility’s energy profile and provides timely delivery of energy during peak periods to help save on electricity costs. Electric vehicle (EV) and compressed natural gas (CNG) stations provide a touchpoint for arenas to interact with their community, offering patrons an opportunity to charge or fuel their vehicle while watching the game.

SOLUTION: HEAT RECOVERY

Constellation and the NHL have teamed up to improve the energy efficiency of hockey rinks. Constellation offers solutions that package state-of-the-art technologies with creative financing options.

Waste management is an important operations issue for arenas, as generation and disposal has substantial financial and environmental implications. Because waste to landfill is particularly costly and produces greenhouse gas emissions, arenas should consider opportunities for source reduction, reuse, recycling, composting and material donation.

Research, analysis and implementation of effective environmental programs and operations rely on internal people to champion the process.

Reverse Osmosis To reduce both water and energy consumption, ice rinks can utilize reverse osmosis technology to purify the water used in ice creation without chemicals. The system produces demineralized water that is free of impurities, resulting in a desirable hard, fast ice surface that requires less maintenance, flood water and refrigeration energy, and also saves on wear of the ice resurfacers. The Sweet Spot for Freezing Water Typically, resurfacing water is between 140°F and 160°F. While there is financial and environmental cost in heating water for resurfacing, hot water holds less air than cold water, thereby creating a less porous and stronger ice surface. Today, cold water flooding remains ineffective and heated water above 160°F provides little benefit.

Food and beverage service areas, concessions stands and vending machine areas all require energy to keep your guests’ food hot and their drinks cold.

The temperature of the ice arena air has a significant effect on both the energy consumption of the refrigeration unit, as well as heating energy needs. Arenas will find it costly to heat locker rooms excessively which not only requires energy to heat the air but also requires additional energy to operate the refrigeration system because of heat transfer.

HVAC & Dehumidification

SOLUTION: CONVERSION FLOORS

Arena operators looking to protect their ice surface when hosting off-ice activities typically rely on a conversion floor cover that is both durable and non-absorbent. These conversion floors are traditionally made of fiberboard, plywood or composite material.

Greener cleaning initiatives can improve arena operational efficiency and savings. These strategies include using cleaning processes that reduce energy and water use, decreasing the number of cleaning products, and switching to high-efficiency cleaning equipment and ecologically preferable sanitary paper products. For a guide to bringing better practices to your arena, check out the Green Sports Alliance’s Playbook.

Electrical

Installing high insulation value windows and weather stripping on doors and windows will lower an arena’s energy loads. The exterior surfaces (roof and facades) of the arena should in a hot climate have high solar reflectance and high infrared emissivity in order to reduce space-cooling loads.

WATER PURIFICATION

SOLUTION: SUSTAINABILITY REPRESENTATIVE

A rink’s ceiling plays a major role in the quality of the ice. The temperature within rinks varies greatly from the ceiling to the ice. The ceiling is warmed by outdoor elements, such as the sun, as well as indoor factors, such as waste heat from equipment. This heat is constantly radiating down from the ceiling to the ice surface which could cause the refrigeration system to work harder to produce the desired ice conditions.

Aside from the water intensive ice-making and resurfacing process, water is used in- arena for plumbing, food services, landscaping and cooling towers. An average arena can use thousands of gallons of water per day and most arenas send used water straight into sewage. Arenas that use water efficiently can reduce costs through lower fees, sewage volume and energy and chemical use.

Educate staff in kitchens on energy required by equipment such as ovens, grills and kitchen hoods and encourage staff to limit the time this equipment is on during non-service hours (pre and post-game). Upgrades to new EPA Energy Star certified commercial concessions equipment provides an immediate opportunity to improve energy consumption. Automatic venting for range hoods can help staff by shutting off the appliance when no longer needed, saving energy. New refrigerated beverage vending machines that have earned the EPA Energy Star certification are, on average, 50% more energy-efficiency than standard machine models and can save arenas approximately 1,700 kWh per year. Consider upgrading arena vending machines that incorporate more efficient compressors, fan motors, and lighting systems – with low-power modes for off-peak hours – to keep beverages just as cold and the machine visible while using less energy.

ICE RESURFACERS

Back to Overview

GREEN CLEANING PRODUCTS

Laser Leveling Technology New laser leveling technology for ice resurfacers can help provide consistency in the thickness of the ice sheet, which helps save water, energy and labor. The technology, which can be retrofitted to existing ice resurfacers or factory-built on new ones, help spray a precise, consistent layer of hot water for a safer, faster, and smoother ice surface. Ice Monitoring New technology in ice monitoring also now provides sensor data – including ice and air temperature, brine supply and return temperature, humidity and dew point – to assist rink operators in decision-making.

Lighting Improvements

See the Solution

Off the ice surface, the lighting needs of concourses, concession areas, stairwells and parking decks consume valuable energy and resources. Today, lighting technology has made upgrades in these areas known as “low-hanging fruit” within the industry, with great potential for electricity savings, reduced maintenance time and cost, and lower environmental impact.

The arena’s ice plant generates significant heat as a byproduct, which can be can be re-used in various ways, such as ice melting, space heating, domestic water heating, dehumidification and subfloor heating. Energy recycling is not only an environmentally sustainable practice, it is also cost-effective.

Upping Efficiency Building (or energy) management systems are a proven tool to help arenas keep energy and water systems operating efficiently, by controlling refrigeration, temperature and humidity levels, and water heating equipment. These systems tell operators of critical issues and enhance the staff's ability to make changes in settings that otherwise would result in inefficient operation. Optimizing Energy New continuous recommissioning systems can now control existing building management systems, processing and analyzing numerous data points and variables to automatically execute an optimization plan for the arena. Small, incremental changes to key systems (refrigeration, lighting, HVAC, etc.) can add up to substantial savings on energy consumption.

REFRIGERATION SYSTEMS

Much of an arena's floor, particularly the perimeter of the ice surface, is covered with rubber matting to protect skate blades and improve grip and traction.

Electrical

Constant and efficient humidity control is vital to the maintenance of a good ice sheet. Humidity, if uncontrolled, can result in fog, rust, corrosion, condensation and poor ice conditions — all of which compromise skating performance and safety, spectator enjoyment and longevity of the arena. Excess moisture in areas such as locker rooms encourages mold growth and bacteria, which impact occupant health and indoor air quality. Humidity also causes an increased load on the ice-refrigeration system, resulting in higher energy consumption and increased operating costs.

Paint Paint with the most hiding power (opacity) requires a smaller amount tocover the surface for adequate gameplay. With respect to the paint itself, to the extent it provides better thermal conductivity than ice and has a high infrared reflectance value less energy will be required to maintain desired ice temperature. Also, paint that does not contain hydrant lime or free alkalinity is more likely to increase surface hardness and lower freezing points, reducing energy costs. Though most ice paints are considered environmentally friendly, all must be disposed of properly. Arenas should consult with the appropriate local authorities for approval of acceptable methods.

Low- to No-Cost Improvements in Waste Management Some improvements in waste management can be made through low- or no-cost measures. Ecologically smarter procurement policies and sorting practices, right-sizing equipment, reducing pickup collections and ensuring accurate tracking of all materials can result in lower waste-disposal fees. Easy Ways to Make a Big Impact Simple measures such as placing more recycling bins throughout the arena (to create a 1:1 waste-to-recycling-bin ratio) can result in a significant impact, as can some more-innovative practices, such as composting (available in some markets), selling used cooking oil for conversion to biofuel, and installing a bio-digester that turns organic waste into water safe for discharge. The most effective waste diversion programs have strong cooperation not only from operations staff but also from players and guests – communication to these stakeholders is important. Facilities should also consider implementing programs to collect and reuse hockey equipment.

Electric Vehicle Charging

Less Carbon, Lower Costs NeUnderstanding AHUs The energy efficiency of air handling units (AHUs) begins with understanding the make and model, which spaces they serve and whether they are constant or variable air volume systems. AHU Best Practices AHUs should be right-sized, properly maintained and optimized, by adjusting sensor feeds with the help of scheduling data integration or by switching them off in unoccupied areas (typically as part of a building management or automation system). Variable frequency drives on fan and pump motors can result in significant cost savings. In addition, due to the specific nature of an ice rink, heat recovery ventilators (HRV’s) or energy recovery ventilators (ERV’s) are often well suited to both improve the internal environment while minimizing operating costs. For arenas upgrading HVAC systems, look for more efficient, cost-effective models that have EPA’s ENERGY STAR certification. Ceiling Fans High-volume, low-speed ceiling fans can improve cooling, increase air circulation and support dehumidification.

Natural Refrigerants: Ammonia and CO Facilities in need of a replacement of their ice plant may consider natural refrigerants, such as ammonia or CO . Both ammonia and CO are naturally occurring refrigerants with zero ozone depleting potentials (ODP). The global warming potential (GWP) is zero for ammonia and one for CO , significantly lower than synthetic refrigerants. Ammonia Refrigeration Systems Where regulations allow, ammonia systems boast certain advantages that include a highly efficient refrigeration cycle, with low operating pressure and significantly lower potential for ozone depletion and global warming than synthetic HCFC and HFC refrigerants. No system is perfect, and ammonia does require proper maintenance and security to protect against its own toxicity and flammability, so arenas moving in this direction should work closely with their engineers, consultants and other experts, along with their local governments. CO Refrigeration Systems CO , also a natural refrigerant, is non-toxic and a promising development for environmental progress. CO systems, while efficient in colder climates, have lower efficiency of the refrigeration cycle in the summer or in warm climates. Extra Energy Savings Regardless of the system, arenas may consider installing high efficiency compressors, NEMA Premium efficiency motors, and variable speed drives on pumps – for additional energy savings. New ice surface temperature controls – technology that communicates in real-time with the refrigeration system to help maintain a desired ice temperature -- can sync with facility schedules, analyze ice conditions and react to building temperature fluctuations.

ON-SITE ENERGY

For decades, the ice on which the game is played has been illuminated by high intensity discharge (HID) and fluorescent lights. Recent technological developments in arena sports lighting have improved dramatically, offering products that help lower operating cost and improve the player, fan and guest experience.

Traditionally, three primary types of mechanical systems keep ice rinks dry: air handlers, cooling-based systems and desiccant-type dehumidifiers. For situations with a significant humidity challenge, air handlers and cooling-based systems are often ineffective methods for dehumidifying ice rinks. Desiccant dehumidification systems are energy efficient, delivering dry air into the arena, while optimizing ice conditions, reducing refrigeration load and easing the workload of the compressors. New compact desiccant technology can remove 2 to 3 times the moisture of a conventional refrigerated dehumidifier and be mounted on an existing platform. In addition, recent innovations now use waste heat from refrigeration compressors — rather than natural gas or steam — to regenerate the desiccant wheel. Microprocessor dew point controllers help sense and efficiently adjust for optimal humidity levels.

HEAT RECOVERY

SOLUTION: LOW-E CEILINGS

Each facility should designate a sustainability representative responsible for understanding energy, water and waste management. This person should be accountable for data collection, project implementation and fostering environmental stewardship within their organization and the community. Communicate your efforts and successes to your patrons through in-arena signage, staff education and social media. To get started, visit the Green Sports Alliance’s Operations Roadmap.

An arena’s ice conditions impact gameplay, energy and water consumption, as well labor resource needs. Ice thickness should be based on the facility use schedule, the level of skating and the energy performance of the building. As little as ½ inch of ice unnecessary ice thickness produces an increase in required compressor work and associated operating costs.

BUILDING CONTROLS AND AUTOMATION

Rubber matting with recycled content is a less expensive and more durable choice than virgin or synthetic rubber. Reclaimed rubber also requires less energy in the production process, offers a viable way to dispose of unwanted rubber products (such as tires), and conserves non-renewable petroleum products used to produce synthetic rubbers.

DEHUMIDIFICATION

Less Carbon, Lower Costs New ice resurfacers with highly efficient engines can emit considerably less carbon dioxide (CO ) and provide a lower cost of operation, with the potential to save greatly on fuel and maintenance costs. The Electric Option New state-of-the-art electric ice resurfacers and edgers provide a tailpipe emission-free option, helping to reduce a facility’s carbon footprint. Electric ice resurfacing equipment offers a solution to improve indoor air quality, while reducing operating expenses related to energy purchasing, maintenance and ventilation.

In locker rooms and restrooms, upgrades to low-flow or waterless units can result in a substantial amount of water saved while lowering costs associated with consumption, discharge and maintenance. Low-flow fixtures and valves for toilets and urinals, as well as electronic sensors, can contribute greatly to reduced water use. A water management plan should identify potential opportunities for reducing water losses and consider reclamation, reuse and rainwater harvesting. Today, technology exists allowing arenas to cut consumption by reusing the water from collecting and using rainwater from the roof or other impervious surfaces. Facilities can also achieve water savings outside through drought-resistant landscaping practices. To save on energy costs associated with heating water, new on-demand hot water heaters can provide benefit for flood water, showers, sinks and concessions.

Professionally formulated white ice paint, with an application and disposal plan, is important to both game play and the environment. Quality ice paints have been proven to reduce refrigeration costs by reflecting heat away from the skating surface. The marketplace contains a variety of products that will require careful consideration to ensure the best return on investment. Though most ice paints are considered to be environmentally friendly, all must be disposed of properly. Ice rink staff are environmental stewards that must take care with all products used in the facility.

Better Lighting, Higher Efficiency Compared to high intensity discharge (HID) and fluorescent systems that have long dominated the vast amount of space under arena ceilings, light emitting diodes (LEDs) can achieve greater illuminance and improved energy efficiency, resulting in energy cost savings. LEDs Ready for Action LEDs produce more light than metal halides while consuming far less electricity. Heat from old lighting technology reaches the ice, requiring more energy to prevent melting. Older systems also take time to warm up, while LED lights turn on immediately and last much longer. Energy efficient LED technology is now ready for game lighting purposes (above the ice sheet) to help reduce glare and improve game presentation, guest experience and visibility for players.

Fossil fuel-powered ice resurfacers and edgers (i.e., those powered by gasoline, diesel, propane and natural gas) create greenhouse gases which impact the environment and contribute carbon monoxide and/or nitrogen dioxide indoors. Improperly maintained equipment can result in a significant increase of these emissions.

The Future of HCFC-22 HCFC-22 (or R-22) is used as a refrigerant in many ice rinks across North America because of its cooling efficiency. Despite the production and importation phase-out, virgin HCFC-22 exists and recovered and reclaimed material will be available, so use of HCFC-22 is expected to continue in the near future. Limited Supply Means Rising Prices However, given the pending supply limitations, prices for HCFC-22 are rising, which makes tightening leaks and performing preventive maintenance for existing HCFC-22 systems even more important to keep refrigerant emissions down and reduce the need to purchase additional HCFC-22. Natural Refrigerants Moreover, in light of the phase-out of synthetic HCFCs, alternate natural refrigerants including ammonia and CO2 are available and viable. See ‘Refrigeration Systems’ for further detail on these alternatives.

Managing Energy as a Strategic Asset Thanks to the ongoing evolution of the energy industry, businesses today have a wide range of opportunities to manage energy efficiently as a strategic asset and maximize the value of their energy investment. From simple fixed price and index arrangements to a variety of advanced strategic solutions, arenas can look to structure pricing and minimize volatility. Reducing Energy at Peak Times Peak load management can also help arenas reduce overall energy costs by voluntarily curtailing energy usage at predicted peak hours in a way that does not affect arena services. In some regions, alternative sources of energy — including that produced through deep-lake water cooling, hydro, cogeneration and geothermal — can be integrated as well.

Two Ways to Save Energy Through Lighting There are two main ways to save energy used for lighting: (1) use more energy efficient lighting; and (2) reduce the operating time of the lighting. Inefficient fluorescent lamps (T12 and T8) remain a popular lamp used in hockey arenas. Advancements in LEDs provide opportunities for arenas to reduce operating costs and environmental impact in both front and back-of-house areas. What Else to Consider To further reduce energy spent on lighting, arena operators should consider occupancy and daylight sensor controls, as well as timer and scheduling programs in their lighting- control systems.
