Leading the Social Housing Sector Towards Sustainability

In a challenging economy, Ottawa Community Housing (OCH) has successfully matched a desire to make the world a better place with the need for more financially sustainable operations. The outcome is a more comfortable living environment for tenants, significant savings to the bottom line and a remarkable reduction in our carbon footprint. Pioneering environmental initiatives has placed OCH on the national stage to share our successes to benefit the social housing sector as a whole.

OCH Pillars of Sustainability

Taking a holistic approach to greening OCH has meant focusing sustainability efforts on three pillars.


Our buildings

Our people


Our culture



Lower utility costs


Diverting waste


Conserving energy


Reduced emissions

Did you know?

OCH has saved $64.1M

due to solar panels, home weatherization program, water, windows and door retrofits.

  • Peer Presland


    Construction on the retrofit was completed in 2021.


    PEER uses 24, nine-foot by 20-foot panels to create new outer walls for the four townhomes. The homes received a new roof, new windows and a bank of 34-kilowatt solar panels that will produce more energy than the homes use each year. The project will reduce the Presland Avenue townhomes’ energy consumption for heating by 90%. The project is a partnership with Natural Resources Canada.

  • Maintenance Vehicle Fleet




    Introduction of smart cars in the fleet is helping to reduce fuel consumption and emissions.

  • New Developments


    Ongoing since 2014


    Green building technologies and approaches in all new construction are building higher performance homes.

    Examples of new builds include:

    Use of heated floor systems, regionally sourced building materials selection, LED lighting, EnergyStar appliances, waste diversion systems, all promoting sustainable and resilient buildings, equal lower costs on maintenance and utilities in the long term.

  • Waste Diversion Program


    Launched in the fall of 2016 in partnership with the City of Ottawa


    After the pilot project, paper and cardboard collections increased by 140 percent, and glass, metal, and plastic collections increased by an average of 196 percent! 

    Since those initial pilots, OCH has completed work in 24 communities that aim to reduce waste and encourage the use of green bins.

  • Race to Zero Pledge

    Ottawa Community Housing Corporation is proud to announce we are joining the City of Ottawa’s Race to Zero Pledge amongst organizations such as Carleton University, Minto and the National Arts Centre. Along with our partners at the City, we have joined a United Nations-led coalition of cities, businesses and institutions to enact climate action. 

    The pledge aligns with OCHC’s own Energy and Conservation Strategy, which aims to reduce our carbon footprint by using the highest standards of sustainable design practices for new buildings and retrofits. As part of that plan, we also added green infrastructures – such as 37 solar arrays in communities across the city and solar walls.  

    Much of the work to move towards a more sustainable and greener portfolio depends on funding commitments from partners at all levels of government. One example is the recent $200 million commitment from the CMHC and Co-Investment Fund, which will allow us to complete deep-energy retrofits on several buildings. This will allow us to reduce our carbon emissions by 7,000 tonnes per year – the equivalent of taking 1,512 cars off the road every year.

Case Studies

Results of Completed ECO² Initatives





Designed to reduce energy waste, the system was installed in two high-rise buildings. After one year, there was a 31% reduction in the energy consumption while maintaining tenant comfort. This system was deployed in an additional eight buildings and will likely be rolled out to all electricity-heated buildings.

This system is capable of regulating the heating energy allocated to each apartment unit based on several criteria including local outdoor temperature, floor level and orientation.

2011 – 2013


Award-winning retrofit of 15,000 homes with new high-efficiency toilets, showerheads, and basin aerators has reduced water consumption by 1.6M cubic meters of water annually. Old fixtures were crushed and distributed for road aggregate; metal and plastic parts were completely recycled.

Ottawa Community Housing (OCH) saw an opportunity to save water and money by retrofitting plumbing fixtures throughout its portfolio. Early analysis suggested that new water-efficient fixtures would use less water, reduce undiagnosed leaks and offer significant cost savings. OCH was also motivated to lower its water consumption to reduce its impact on the environment.

2011 – 2012


To date, 37 solar arrays have been installed and have the capacity to generate 500,000 kWh. That is more than 43 million smartphones charged 

Solar installations represent over $3.3 million of clean electricity or energy conservation annually.

The replacement of 8,500 sq. ft. of brick cladding on the exterior wall at one 17-storey apartment, with a solar wall that preheats air supplied to the building’s corridor ventilation, has netted a 21% reduction in natural consumption annually at that property.


The brick cladding at Clementine Towers (1455 Clementine Ave) required replacement to address deficiencies and deterioration. This offered an opportunity for Ottawa Community Housing (OCH) to install an innovative “solar wall” to preheat air supplied to the building’s corridor ventilation system. The project reduced energy consumption and operating costs while showcasing green building practices.

Ongoing since 2012


Participating in Enbridge’s ‘Home Winterproofing Program’, OCH has worked with the EnviroCentre to retrofit uninsulated basements of hundreds of townhomes. In the four largest communities where insulation and sealing were completed in 611 homes, collectively tenants are seeing an estimated annual natural gas savings of $91,000.

Ottawa Community Housing (OCH) had an opportunity to save energy, improve the building conditions and enhance tenant comfort in its townhouse communities by retrofitting uninsulated and poorly sealed basement walls.

Our success in sustainability is thanks to many important contributors and sustainability-focused organizations such as:




Hydro Ottawa

City of Ottawa, through its Climate Action Plan

Federal and provincial programs

The original greening efforts 2010 and the Gren Plan of 2011 enabled OCH to begin a sustainable transformation through various pilot projects. The plan also prepared OCH to access generous incentives to make additional pilot projects even more feasible.

In April 2016, OCH was awarded $12.2M in SHARP funding from Ontario’s Green Investment Fund to refurbish aging buildings in the portfolio with retrofits such as energy-efficient boilers, insulation and windows. This funding allowed us to better meet the modern challenges of climate change despite our housing being constructed in the 1960’s and 1970’s.
