180 Wellington West Refresh

Built almost 40 years ago, the office tower at 180 Wellington Street West is situated in the downtown Toronto core. To accommodate increased occupancy, the 12-storey building needed a refresh and new office space. Tenant retrofits were performed on 11 floors of office space to increase floor space and to improve tenant comfort. The first floor was fitted for amenities.

HH Angus provided mechanical and electrical design for the base building and interior upgrades to primary air handling systems, electrical distributions, and to washrooms throughout the floors.

Our project scope included 150,000 ft2 of tenant fitout, building recladding and base building upgrades, fire alarm replacement, perimeter fan coil system replacement, emergency power system and normal power system upgrades, as well as humidification system upgrades.

The key design challenge was how to answer the client’s expressed desire for increased visual transparency of the building’s exterior without creating a major penalty in energy efficiency. The design team recommended a solution, and we worked with the Architect to determine appropriate curtain wall components to achieve the client’s goal.

The building has been certified LEED EB Platinum.

Benefiting the client

Our design included more perimeter glazing and daylighting without an energy penalty, and decreased lighting density by 7 watts/ft2.

Reducing energy costs

We designed a whole new lighting layout for the entire building, complete with photometrics, LED technology, daylight harvesting and occupancy controls help reduce lighting density.
