EY Tower


Designed by Kohn Pedersen Fox Associates and WZMH Architects

This 40-storey state-of-the-art tower replaces, and in part incorporates, the former Concourse Building. Only a reconstituted façade of that Art Deco heritage building will be retained. This new build will be the third phase in the well established Richmond Adelaide Centre where lead tenants - Ernst and Young and The TMX Group - will join neighbours like TD Bank and Google via a PATH concourse connection. The new building is largely pre-leased.

The design has been completed entirely in 3D Revit software. It features an expansive 23,500 square foot average floor plates optimized for open and collaborative workspace. 9'6"" ceiling heights will showcase the floor to ceiling windows on each level. Environmental standards are a big part of this project where the building will not only feature on-demand fresh air, daylight and motion sensors, electric car parking, a high performance building envelope and mechanical systems, state-of-the-art lighting controls, bicycle storage, as well as change rooms. The building also introduces something called a ""Green Lease"". This stipulates how occupants manage, occupy, and operate the building in a long-term, sustainable way.

The EY Tower achieved LEED Platinum Core & Shell certification.

S + A Services Included:


The building features Enwave district cooling and a peak shaving chilled water plant located in the penthouse. Chilled water return is used as a condenser water system for the supplementary cooling system for future tenant needs. Boiler system is a variable primary high efficiency condensing plant. Building make up air units use return water from the chilled water plant energy recovery using building exhaust air to pre-cool and pre-heat fresh air. Make-up air units are also complete with enthalpy recovery wheels for exhaust air energy recovery. It is a variable flow compartment unit system with interior VAV and perimeter fan powered boxes complete with ECM motors. Perimeter diffusers use switchover technology to heat the windows in the winter negating the need for low level heat even though there is floor to ceiling glass. It is a dedicated outdoor air system introduced at the perimeter and into the compartment system for interior zones using CO2 sensors to adjust fresh air. The building has a cistern reusing water for irrigation and water efficient fixtures in all the washrooms. The BAS system is IP based, power over ethernet, and is connected into the common communication backbone. Meters have been provided on all major systems for verification and to track energy usage. The building is fully sprinklered.
