George Vari Engineering and Computing Centre, Toronto Metropolitan University

Toronto, Ontario

Project Description

The new Centre for Computing and Engineering located on the urban campus of Toronto Metropolitan University (previously Ryerson University) in the heart of downtown Toronto features a sculptural treatment of the Church Street facade that dramatically changes throughout the day as the sun and ambient light varies.

Crossey Engineering provided the Mechanical and Electrical design services for this downtown 230,000 sq. ft. building. This project includes tenancy for the Computer Sciences Department with hardware and software labs, lecture halls, faculty offices and engineering labs for aeronautics and structural groups.  The mechanical design uses city central services of steam and chilled water for primary energy sources.

The main challenges of this project included the distribution and adequacy of services to meet the needs of high occupancy and variable loads, high energy efficiency design, the reduction of background noise levels on a tight budget. The significant energy-efficient design features include the following:

  • Efficient VAV and lighting systems.
  • More effective thermal envelope.
  • Energy from equipment used to reheat supply outdoor air.

The VAV systems utilize variable frequency drives (VFD) for fan modulation and CO2 demand-controlled ventilation (CO2 controlled ventilation efficiency not included in CBIP overall efficiency calculation). VFD modulation was also used for the heating and cooling circulating pumps.

An efficient lighting plan was employed typically using fluorescent fixtures with T8 lamps and electronic ballasts controlled by occupation sensors.

Due to the sustainable technologies considered in the building design, a $60,000 grant was awarded as the Ryerson building was found to be 28.9% more efficient than the reference MNECB building.
