Maple Leaf Square Mixed-Use Complex and Hotel Le Germain

Maple Leaf Square is a 1,700,000 ft2 mixed-use high-rise in downtown Toronto. The facility provides sports and entertainment space, two condominium towers, parking, office and retail space, and also includes Hotel Le Germain. HIDI partnered with KPMB, Page + Steele and Lemay Michaud Architects (hotel) to provide mechanical, electrical and communications consulting services. The project successfully achieved LEED Silver certification and is valued at roughly $500 million.

In support of its LEED target, the mechanical design incorporated a number of features to maximize energy efficiency, including heat/energy recovery wheels for all central air handling systems; pre-cool/reheat runaround systems for all residential make-up air units; direct steam injection for humidification from Enwave’s supply; in-suite heat recovery ventilators for all residential suites; and domestic water preheat using waste steam condensate heat. In addition, rain water and steam condensate collected in the storm water cistern and used as gray water for irrigation and miscellaneous non-potable water demand achieved exemplary performance in potable water saving under the LEED system.

The project design also incorporated comprehensive fibre optic and copper cabling services, as well as a satellite dish farm on the roof to support both residential and retail tenants.
