Building Systems Design Guidelines

Infrastructure Ontario's Building Systems Design Guidelines were developed to standardize the design, construction objectives and technical requirements for IO's portfolio of buildings. This in turn helps our organization and our partners achieve improved operational performance, energy efficiency and increased occupant comfort and satisfaction.

Consultants working with IO are required to use the Building Systems Guidelines for the following types of projects:

• New construction
• Renovations
• Additions
• System/equipment replacement and refurbishment

For many projects, multiple design solutions are available and should be evaluated during the early stages of design to determine the optimum solution for the project. On this basis, IO requires the Design Consultant to identify Design Options and evaluate these options. The analysis should include capital cost, life cycle cost, energy efficiency and performance advantages and disadvantages.
