In 2017, the Canadian Federal Government announced a target to reduce greenhouse gas emissions by 80% by 2050, relative to 2005 levels. Reducing the emissions produced by residential and commercial buildings will be fundamental to hitting this target since homes and buildings currently generate 12% of Canada’s emissions.

Net zero building

Ontario is constructing net-zero buildings at increasing speed to reduce the emissions from buildings. A net-zero building produces enough renewable energy to cover its annual energy consumption. They are highly efficient, with excellent insulation and heating, ventilation, and air conditioning (HVAC) systems. 

Various municipalities in Ontario have committed to supporting the construction and retrofitting of net-zero buildings with funding programs, including:

  • Toronto, where all buildings built after 2030 will be made to near-zero emissions standards.
  • Halton Hills, which has pledged to be net-zero by 2030. 
  • Markham and Burlington, which have vowed to be net-zero by 2050. 

In the future, a growing number of Ontarian municipalities will be launching programs to promote net-zero buildings as a solution to reduce their emissions.

City of Toronto’s first Net-zero Childcare Facility – Mount Dennis Childcare Centre

Greensaver is working on an innovative childcare facility for the City of Toronto. It is to be located at 1234 Weston Road, within the Mount Dennis area, at the corner of Weston Road and Glenvalley Drive. The building is designed to be Net Zero Energy and to meet the Canada Green Building Councils “Zero Carbon Building Program”.

The project will be a groundbreaking case study on creating a net-zero energy institutional facility using envelope enhancements, geothermal PV/T on-site energy.

As the Canada Greensaver insulation team, we are proud to implement our profession in this energy conversion project.

What Can Greensaver Offer?

Greensaver team

For more than 30 years, Greensaver has delivered energy conservation programs across Ontario. We are the lead delivery agent for Ontario’s principal energy conservation programs: the Save on Energy Energy Affordability Program, and the Enbridge Home Winterproofing Program.

This wealth of experience makes us the most suitable choice for municipalities looking for support to run programs encouraging their residents to transition to net-zero. Greensaver can manage programs from start to finish, drawing on the experience of our various departments:

Program Design

Greensaver has played a crucial role in designing electricity, gas, and water conservation programs in Ontario. Our efforts have lead to optimized participation and results for our clients.

Outreach and Marketing

Our Outreach and Marketing team has extensive experience promoting energy-saving programs across Ontario. Promotion can occur in-person by a dedicated outreach team, or digitally through skillful digital marketing campaigns.

Vendor & Contractor management

Over the years, Greensaver has compiled an extensive network of contractors across the province. These contractors are capable of completing any work towards net-zero that we cannot do ourselves.


The administration of programs is instrumental in turning plans into reality. Greensaver can support application reviews, manage contractor networks, and evaluate and measure results.


Our Client Support team can manage all customer needs, including both inbound and outbound calls. Our highly trained Customer Service specialists guarantee an excellent level of customer care. 


Our energy advisors are experts in many of the technologies required in net-zero buildings, including building envelope upgrades, heat pumps, HVAC technology, and renewable energy sources.

The Creation of a Community Energy Plan

Volunteering in the community

Greensaver has extensive experience creating Community Energy Plans to meet local municipalities’ requirements and can replicate such a plan to help you meet your net-zero targets.

The key starting point for the Community Energy Plan is determining the right strategy for your municipality. This includes setting priorities and bringing forward suitable measures to achieve the target savings. 

Additionally, we undertake economic and business case modelling and analysis to optimize the return on investment of program measures. 

Net Zero Work

Through the programs we currently deliver, Greensaver can complete much of the work required to make buildings net-zero. We have over 150 staff members, 100 field resources, and 20 subcontractors to offer full-service solutions.

Building Envelope

Building Envelope Upgrades

A building’s envelope refers to the physical separator between the exterior and interior. Net-zero structures effectively control the flow of heat, air, and moisture in and out of the building to achieve a high level of efficiency. 
Greensaver’s highly trained installers can upgrade a building’s envelope by improving insulation, sealing air leaks, and installing high-quality windows and curtain walls.

Heat Pump

Heat Pumps

Heat pumps provide efficient heating by extracting heat from outside air, the ground, or a water body, and redistributing it. They also provide cooling in summer by removing heat from indoor air.  Greensaver has installed lots of heat pumps across Ontario for the Affordability Fund Trust Program. 

Hvac system


HVAC systems control a building’s air quality and maintain a comfortable temperature. Net-zero buildings use intelligent HVAC systems to reduce waste and save energy. 
Greensaver has comprehensive experience installing smart thermostats and building energy management systems, which avoid unnecessary running of HVAC systems and improve building efficiency.

Low Carbon Water Heating

Low Carbon Water Heating

Net-zero buildings reduce emissions from water heating by improving the efficiency of the water heating itself or changing to a lower-carbon energy source. 
Greensaver has significant experience in reducing water heating emissions, through electrification, greywater heat recovery, and installing solar water heaters.

High efficiency lightbulb

High-Efficiency Lighting

Net-zero buildings utilize high-efficiency lighting, such as LED bulbs, to reduce energy consumption. Greensaver has replaced thousands of old bulbs with LEDs while delivering energy conservation programs in Ontario.

Light switch

Reduced Plug Loads

Plug loads are the energy used by appliances plugged into outlets. Net-zero buildings reduce this energy by using more efficient appliances or smart power bars that automatically switch off devices when they are not in use. 

Greensaver has years of experience installing ENERGY STAR-rated appliances, including refrigerators, window air conditioners, dehumidifiers, high-efficiency showerheads, and smart power bars, for our program customers.

Rooftop Solar PV

Rooftop Solar PV

Net-zero buildings take advantage of rooftop solar panels to generate electricity and offset the building’s energy consumption. 

Greensaver has experience installing rooftop solar panels across Ontario and can help you design a program for your community.
