Toronto GREEN Development Standard [January 2007]
The Toronto Green Development Standard provides an integrated set of targets, principles, and practices to guide the development of City-owned facilities and toencourage sustainable development amongst the private sector. The Toronto Green
Development Standard was created from a review of City guidelines and targets, popular private rating systems and the experiences of cities from around the world.
Structure of the Standard
The Standard is presented in two charts in the following pages.
The first chart is for mid- to high-rise residences, commercial industrialand institutional development.
The second chart is for grade-related residential development.
This Standard is rooted in the key environmental drivers for the City. These are:
Better air quality Reduced greenhouse gas emissions and urban heat island effects Greater energy efficiency Improved water quality and water efficiency Less solid waste Protection of the urban forest and wildlife habitat Reduced light pollution
The Standard is based on a number of principles, many of which were identified inconsultation with key stakeholders: The principles are that the standard be: measurable (e.g. plant shade trees to provide a 20% canopy at maturity); performance orientated (e.g. achieve 25% energy savings above the Model
National Energy Code) to allow for flexibility such that innovation is encouragedto meet performance targets;
focused on the design and construction of the built form (not on buildingoperations or workplace programs that could also influence environmental
performance); user friendly, and set high enough to raise the bar on environmental performance but still allow for
green competition amongst developers.
Made in Toronto Of particular
interest to the Cityof Toronto is that
any greendevelopment
standard it adoptsand promotes
must address itskey environmental
drivers. Thestandard shouldreflect the Citys
climategeography, urban
infrastructure, andlegislative context,
and help Toronto
achieve its ownparticula
environmental objectives.

Toronto GREEN Development Standard [January 2007]
The first column in the charts identifies the development features (building and siteelements) that can affect Torontos environmental drivers. Examples includeventilation, energy efficient fixtures and appliances, and building orientation.
The second column identifies existing City standards, targets or guidelines for specific development features. Examples include standards such as the provision of
bicycle parking found in the Zoning By-law, the target to increase sustainable treecanopy by 30-40% as identified in Our Common Grounds , and guidelines such as theinterim Wet Weather Flow Management Guidelines.
In reading the chart, it should be noted that the Ontario Building Code is the existing
baseline standard for many of the development features. Recently, the Province proposed changes to the Building Code that raise the bar on energy efficiency andremove barriers to green technologies. Toronto City Council supported the mostaggressive of these options at its meeting in April, 2006. The proposed GreenDevelopment Standard meets or exceeds the proposed amendments.
The third column identifies the Toronto Standard or level for green for eachdevelopment feature. The Toronto Green Development Standard is intended to reflectan enhancement over current City requirements and business practices. It is based oninput from the stakeholder workshops and consultation with the Green DevelopmentStandards Working Group. It is also based on proposed enhanced City guidelines
and/or practices and on a comparative analysis with other well known standards suchas LEED and Green Globes for each development feature. In other words, eachstandard has a basis in an existing City guideline or practice, and/or in an existinggreen building standard such as LEED, Green Globes, and Energy Star.
Within the third column, elements of the Standard marked with the symbol indicate the core or minimum requirements. The other elements identified in theStandard are considered to be enhancements that would further improve thesustainability of a development beyond the basic Green Standard. Where appropriate,graduated levels of achievement (minimum, preferred, excellent), have beenidentified.
The fourth column of the chart identifies the equivalent or related standard for eachdevelopment feature set by LEED, Green Globes, Energy Star, and other ratingsystems.
The fifth column identifies some possible strategies to implement the proposedstandard, including technologies and products that have been used in greendevelopment in Toronto.
Within the thirdcolumn
elements of theStandard markedwith the symbol
indicate thecore or minimum
requirements.
