Toronto Courthouse


MAT 4Site Engineers had been retained to analyze the feasibility to replace the existing heating system infrastructure, at the Toronto Courthouse (361 University Ave) and Osgoode Hall (130 Queen Street West), which is currently solely depended on district steam (Enwave).

The disentanglement study considered the following:

• district steam service to remain
• Local geothermal system with district steam service (as backup)
• Local hydronic heating plant
• Local hydronic heating plant c/w geothermal system
• Local combined (hydronic & steam) heating plant
• Local combined (hydronic & steam) heating plant c/w geothermal system

The analysis included building thermal sizing load calculations, modeling and simulation of each option in Hourly Analysis Software (HAP) as well as Life Cycle Cost Analysis (LCCA). In addition to financial (capital) impacts the following implications have been considered and discussed:

• Facility interruption: minimization of court services disruptions
• Heritage impacts: Osgoode Hall is a landmark historic site
• Phased fiscal spending approach: distribution of capital spending through a strategized construction


Site investigation & confirmation of as-built conditions, calculations & simulation of the building energy usage, life cycle cost analysis.

In addition, the following list of disciplines had been included to provide a comprehensive assessment:

• Mechanical
• Architectural
• Heritage
• Archeology
• Electrical
• Structural
• Environmental
• Geothermal Specialist
• Civil
• Site Survey
• Ultrasonic Pipe Thickness Testing
