Using Winter Snow to Beat Summer Heat

The City of Ottawa has commissioned a study to explore how snow removed in the winter could be used in the summer to cool buildings. Last winter, the city removed more than 13 feet of snow at a cost of $88 million.

The snow removed in the winter could be insulated with wood chips. As the snow melts into cold water, it could be treated and run through pipes in buildings to cool them. Similar cooling systems are already being used in Sweden, Japan, and downtown Toronto.
