Let snow provide cheap air conditioning during warmer months

UBC engineering professor Kasun Hewage and colleagues have found a way to use snow for air conditioning in warmer months, the Ottawa Citizen reported.

They found that running an apartment building’s air supply through a pile of snow chilled the air for free.

“The potential of this type of system to be used for large buildings and institutions looks promising,” said researcher Rehan Sadiq. “Aside from making good use of waste material, this type of system could eventually help large organizations such as municipalities recoup some of the considerable costs associated with snow removal.”
