What started out as a simple diagram on a napkin in a Hearst restaurant blossomed into one of the most efficient curling rinks in the province.

George Njegovan of Greenviro Engineering took that napkin and transformed the diagram into a geothermal blueprint for success. Check out how we created optimum ice conditions at new Hearst Ontario curling rink.

We designed geothermal freezing of this curling ice, extracting heat from it to heat the rest of the building
