Europe’s cities are turning outdoor ice rinks into roller rinks. How will ours adapt? | 24CA News
Outdoor ice rinks are being changed by curler rinks in lots of European cities as they battle with their prices and environmental impacts in a warming world. But will Canadian cities face comparable choices? And what might be finished to maintain out of doors skating alive?
Here’s a more in-depth look.
It’s been a heat winter throughout a lot of Canada, making slush of the skating season in lots of locations — together with Ottawa, the place it was introduced final week that the long-lasting Rideau Canal Skateway wouldn’t open this 12 months, for the primary time because it was first cleared for skating in 1971.
Earlier that week, in Atlantic Canada, pace skating practices for Canada Winter Games athletes on the Halifax oval have been delayed by heavy rain and temperatures of 8 C that left its floor a big puddle. Meanwhile, the solely rinks open in Montreal for a lot of the winter have been refrigerated ones, also called “artificial ice rinks.”

European, U.S. cities ditch out of doors ice rinks
In different components of the world, below-zero winter temperatures are already unreliable, and chillers, which require numerous vitality to make synthetic ice, are essential.
Many cities in additional temperate climates determined to skip their conventional winter ice rinks altogether this 12 months. In some locations — comparable to San Jose, Calif., Monaco, Bad Neuenahr, Germany, and a lot of French cities, together with Tours and Gembloux — they have been changed by curler rinks. Another French neighborhood, La Test-de-Buch went for an artificial rink made from plastic.
All blamed excessive vitality prices and lots of European cities cited the vitality disaster linked to Russia’s invasion of Ukraine.
That stated, the demise of seasonal out of doors rinks is a pattern that is been heating up in France for a lot of years, the place eco-concious municipal governments have been questioning the environmental and monetary sustainability of ice skating in its warming local weather.
Martin Cohen, the deputy mayor of Tours, France, accountable for the atmosphere, advised the Guardian, “It seemed a bit of an aberration to have an outdoor ice rink when the temperature here at Christmas has been 10-15 C for several years.”

How local weather change impacts out of doors ice rinks — and vice versa
In order for a pure out of doors ice rink to outlive, the typical temperature must be under -5 C, says Robert McLeman, professor of environmental research at Wilfrid Laurier University in Waterloo, Ont. He’s additionally one of many principal investigators of RinkWatch, a citizen science program that tracks the size of the skating season for out of doors rinks throughout the nation.
While this isn’t but an issue within the Prairies, McLeman stated January temperatures are actually close to that -5 C threshold in southern Ontario, the St. Lawrence Valley and Atlantic Canada.
Up till now, many communities in these areas have relied on pure ice rinks for out of doors skating in winter. But McLeman says he is getting extra inquiries about when they should make the transition to refrigerated rinks.
“One of the challenges is the fact that refrigerated rinks are far more expensive,” he stated. “They also use refrigerants and energy, which contribute to the root source of this, which is greenhouse gas emissions.”
Because of the upper expense, communities can afford fewer of them, making rinks much less accessible, particularly exterior Canada’s greatest cities, he acknowledged. “Smaller governments with smaller budgets may simply not have the means to make that transition.”
Even some large cities have been discovering it a problem. Montreal promised in 2016 to construct refrigerated ice rinks across the metropolis, however they ended up costing hundreds of thousands greater than anticipated, delaying building.
The value can even go up because the local weather warms additional. Refrigeration methods want extra vitality to keep up the ice the hotter it will get, McLeman stated. “And there will be days when it’s just simply too warm even for the compressors to keep it cold enough to skate on.”
Canadian cities search for attainable out of doors skating options
Still, many communities see out of doors ice skating as an necessary funding.
Shari Lichterman, appearing metropolis supervisor for Mississauga, Ont., stated the pandemic drove folks outside. “And there’s higher demand than ever, really, for outdoor activities.”
For that motive, the town, which has relied largely on pure ice rinks and indoor ice arenas till now, is wanting into including extra synthetic out of doors rinks.
One of the places that is being thought of for a brand new refrigerated or artificial skating path is alongside the Credit River, which has historically been a well-liked pure skating rink. On the February day that Lichterman spoke with 24CA News, water may very well be seen welling up alongside the banks of the river, and the ice was clearly not prepared to carry the burden of skaters.
Lichterman stated the town is taking local weather grow to be consideration for all its park’s facilities now. “As we look at the winter and we look at ice, you know, we really have to look at synthetic surfaces, certainly refrigerated surfaces — it’s very difficult.”
She acknowledged that these have a excessive value to keep up.
North Vancouver’s extra sustainable resolution
While some components of Canada can count on a future the place a lot of the winter is wet and above-freezing, and are questioning how you can put together, that winter local weather is already a actuality in B.C.’s Lower Mainland.
And but, a couple of years in the past, the City of North Vancouver determined to construct its largest out of doors rink, proper on the waterfront. How they constructed it may provide some concepts for different cities.
Mayor Linda Buchanan stated the town wished to attract folks to its out of doors plaza within the Shipyards District all 12 months spherical, even within the winter, and supply alternatives for actions the place they might join with different folks outside.
Karen Magnuson, the town’s chief engineer, acknowledged that creating an out of doors skating rink in North Vancouver’s temperate local weather was difficult.
The rink was designed with a retractable roof to guard the ice from the solar and rain.
But a key technique was to make use of a CO2 chiller to chill the system. Magnuson stated it is “incredibly efficient” at eradicating warmth from the ice by way of an online of pipes underneath the ice floor, in comparison with different kinds of refrigerants and refrigeration methods.
That effectivity is boosted even additional by feeding waste warmth faraway from the ice into an area district heating system. That supplies scorching water and house heating to native buildings — sufficient to warmth the equal of 43 houses — offsetting the usage of pure gasoline.
Magnuson stated the result’s the Shipyards rink is two-to-three occasions extra environment friendly than a typical ice rink.
The out of doors skate plaza, which opened in 2019 however was shut down for a few years because of the COVID-19 pandemic, will welcome skaters till the top of March. The ice can solely be maintained when the temperature is under 15 C.

Climate-proofing the enjoyment of a winter skate. A climate-themed drag present thwarted by melting ice. Clearing the air with an electrical ice resurfacer. And houses get a winter makeover with some pocket change.
In the summer season, the plaza hosts a splash park and curler skating occasions, and the ice rink’s cooling loop is used to air situation close by buildings such because the Polygon Gallery and the Pipe Shop occasion venue, Magnuson stated.
“I think it’s really important for cities to provide places for the community to come together and play,” she added. “We just need to make sure that when we’re creating these entities, we’re doing it as efficiently as possible.”
