Speaking as someone who runs a home lab in the Canadian prairies, I feel like the cooling requirements as listed in this article are overstated. Sure, I want to pipe waste heat outside during the summer, but in the winter that extra warmth begins to lower my heating bill.
Overall I see heating and cooling as a value neutral proposition, but it also helps that my setup is located in the basement of a drafty 110 year old house.
Speaking as one who skates and skis in cold weather regularly, I must point out that both activities are quite possible at temperatures below -20.
At temperatures below -20 clean ice has a thin film of liquid water which makes it slippery for walking, driving, skating, skiing, dragging corpses, etc... Below that skating and skiing are still possible (and I've done both) since the friction of movement causes the ice to melt a bit.
An important consideration to make in a discussion such as this one is that the temperature of the ice/snow is rarely the ambient temperature. Ice and snow warm and cool more slowly than the ambient temperature changes so the two are rarely the same.
