Toronto Green Standard
PDF Print E-mail

The Toronto Green Standard (TGS) is a two-tier set of performance measures with supporting guidelines related to sustainable site and building design for new private and public development. As of January 31, 2010 new planning applications are required to document compliance with Tier 1 environmental performance measures. There are three versions of the TGS, each relating to different building

  • Low-Rise Non-Residential
  • Low-Rise Residential
  • Mid-High Rise (any use)

The standard and checklist for the multiple category conformances can be found on the Toronto Green Standard website.

Each checklist contains various requirements and concepts that fall into the following categories:

  • Air Quality
  • Greenhouse Gas Emissions/Energy Efficiency
  • Water Quality, Quantity and Efficiency
  • Ecology
  • Solid Waste

IESC provides necessary expertise to determine compliance with the Greenhouse Gas Emissions / Energy Efficiency category of the standard. IESC’s Energy Modelling experts can assist in meeting the Minimum Energy Performance requirements of the TGS.

Minimum Energy Performance

Required Tier 1:

Effective January 1, 2012 the new energy efficiency requirements of the Ontario Building Code (OBC) came into effect that are now equivalent to Tier 1 of the TGS.

Voluntary Tier 2: Minimum Energy Performance

Tier 2 is a voluntary higher level of environmental performance, may be eligible for a Development Charge Refund. Applications for Tier 2 compliance and refund are still required to demonstrate compliance with 35% better than MNECB or 10% better than the OBC (2012) during site plan control application, through the submission of the design stage energy modeling report.

The energy performance and subsequent efficiency improvements must be modelled with EE4, DOE2, eQUEST or other models approved by the City of Toronto Energy Efficiency Office. IESC has extensive energy modelling experience and has successfully completed numerous projects.

IESC is recognized on the BBP approved list of Energy Modelling Consultants and Energy Management Firms.
