Addressing Urban Challenges

• Decoupling urban population growth from greenhouse gas emissions, enabling Canada’s target of an 80% reduction in emissions by 2050

• Enhancing resiliency of buildings and infrastructure, designed to survive and thrive in the face of climate change

Climate Positive refers to the development of neighborhoods with below-zero annual greenhouse gas emissions, at full build-out.

Summary of Public Feedback To Date

Heating and Cooling InnovationsDiscussions around use of lake water for cooling, trade-offs between geothermal/ground sourced cooling, use of heat pump technology.

Building AutomationTo advance sustainability and energy affordability goals, done in a way that respects the privacy of citizens and makes it accessible for everyone.

Public Sector InvestmentSupport for public sector investments, such as Waterfront Toronto contributions towards sustainability solutions.

Solid Waste ManagementImproving recycling (i.e. a market for purchasing waste) and a preference for municipal waste collection.

Mass Timber ConstructionQuestions about potential amendments to the Ontario Building Code in order to provide tall timber buildings, with questions about fire safety in mass timber buildings.

Sustainability of Mass Timber ConstructionQuestions about the sustainability of mass timber construction. In general, they felt that more clarity was needed on the metrics, and where the lumber is sourced.

Local Food ProductionAgriculture and community gardens should be a part of the plans and suggested the latter could be on rooftops.

Summary of Evaluation Results

4

Each of the 56 dots represents one of the proposed solutions related to Sustainability, Resiliency and Climate Positive in Sidewalk Labs’ Draft MIDP.

There are 49 solutions Waterfront Toronto supports including:

10 solutions Waterfront Toronto would support and advocate for policy/regulatory change

10 solutions Waterfront Toronto would support and advocate for government funding

3 solutions Waterfront Toronto would support and invest in

There are 7 solutions that Waterfront Toronto does not support

Indicates the 28 digitally enabled solutions

5

This conclusion does not mean we have approved moving ahead with the project or a partnership with Sidewalk Labs.

It does mean that we see merit in including these solutions in the Draft Innovation Plan for Quayside.

Feedback from this round of public consultation will inform our negotiations with Sidewalk Labs about an Innovation Plan.

Support for certain solutions may change based on feedback from the public, support from Sidewalk Labs (who need to agree with Waterfront Toronto on implementation terms), public policy priorities, and support from governments.

Summary of Evaluation Results

Passive House Inspired Buildings

• Nearly half of Toronto’s greenhouse gas emissions are from buildings (45%)

• High-performance building envelopes critical to reducing use of natural gas

• Key solution for putting Quayside on the path towards Climate Positive

• Also more comfortable for residents, and result in lower energy costs

• Proving viability in harsh Toronto climateMIDP Reference: Vol 2 – Pg. 308

Example of solution to supportwith WT investment

• Underground vacuum tubes separately collect waste, recycling, and organics, reducing waste sent to landfill

• Better waste management reduces the greenhouse gas emissions from cities

• Keeps garbage trucks off the streets, making them safer

• An infrastructure solution proven in cities such as Stockholm and Barcelona

Pneumatic Waste Collection

MIDP Reference: Vol 2 – Pg. 348

Example of solution to supportwith WT investment

• A factory-based, off-site construction of pre-defined building components can take less energy and time to build

Mass Timber Construction

MIDP Reference: Vol 2 – Pg. 225

Example of solution to support,advocate for government funding

• Buildings are also designed to be all-electric, using low-voltage direct current (DC) which will help increase adaptability and safety

• Surface-mounted high-pressure sprinklers use 90% less water to extinguish fires and enable partition walls to be easily movable

Digital electricity (DE) &Mist-based sprinkler system

MIDP Reference: Vol 2 – Pg. 225

Example of solution to support andadvocate for policy/regulatory reform

Sewage Waste Heat Recovery

• Massive source of low-carbon waste heat that could offset natural gas used for heating buildings

• However, not appropriate for Quayside project due to piping distance and high costs of connecting

• Other options include capturing waste heat from nearby sewer pipes (instead of from the treatment plant)
