Stanley A. Milner Library required major upgrades to the existing mechanical system due to the new building envelope upgrades and a new six-storey addition. Arrow’s Mechanical team is proud contributing to this project, which will help to further the redevelopment of Edmonton’s downtown core.

Edmonton’s Downtown Public Library was originally built in 1967 and underwent several upgrades to the central mechanical systems throughout the years.  With the new expansion and wall envelope, the existing mechanical systems were not equipped to handle the new building loads. Arrow’s mechanical work has involved implementing a new chiller, cooling tower, pumps, piping, plumbing fixtures, fire protection, digital controls, fancoil units for HVAC zone control on each floor, as well as new ventilation air systems for the building.  The new mechanical systems are designed and installed to incorporate the latest energy efficient equipment available.

Mechanical system selection was influenced in part by constraints of utilizing existing duct shafts and mechanical space.  Whereas the client preferred a new variable air volume system, a fan coil system was selected to reduce overall capital cost by re-using this existing infrastructure.

The building is being designed to a LEED Silver standard as per the City of Edmonton guidelines and is a prime example of the challenges and opportunities posed by implementing sustainable and LEED design to an existing structure. Arrow’s Mechanical team has worked closely and diligently with the rest of the project team throughout this project, making changes in scope in stride while striving towards an outcome worthy of this exciting project.
