Designated as a National Historic Site of Canada, Crossey Engineering Ltd. provided both electrical and mechanical design services to the interior and exterior restorations and renovations of the Seventh Post Office at 10 Toronto Street, in addition to lighting by Consullux and sustainability design by Gruen.
Approximately 14,000 sq. ft., the beautifully preserved, three-storey structure was originally designed in 1852 and has been employed for multiple uses. Renovations included the building’s four, Ionic columns that stand out front, and the installation of an efficient ground source pump to heat and cool. Heritage lighting and complementing electrical systems were created to be both sustainable and aesthetically appropriate.
As trained commercial geothermal designers, CEL Gruen designed a green room and efficient geothermal ground source heat pump system for heating and cooling of the building.
