Energy Harvesting Project

Low-carbon solutions for heating and cooling

HCE is committed to helping communities recover and reuse valuable thermal energy. Common energy sources ideal for heating and cooling buildings include factories, cooling towers, data centres, sports arenas, water treatment facilities, and power plants.

Currently, upwards of 60% of the energy used from these
and other sources is routinely expelled to our atmosphere and waterways. 

This needs to be addressed as part of the global pursuit
of net-zero.

Energy Harvesting Initiatives

Heat recovery is a proven strategy to conserve energy,
lower operating costs, and reduce GHG emissions. It is also an effective way to stimulate job training, construction, and employment in the circular economy. 

That’s why HCE is leading the way with our Energy Harvesting Project and related initiatives.


HCE is a member of a partnership led by McMaster University and dedicated to integrated community energy systems. A key area of focus is advancing heat recovery and redistribution as a local source of high-efficiency, low-carbon building heating.

ReCharge Hamilton

HCE continues to play a supportive role in the implementation of Hamilton’s Community Energy and Emissions Plan. Among our contributions is a call for building developers and owners to conserve energy and recover waste heat.

Industrial Waste Heat Recovery 

HCE contributed to a project (2019-2020) spearheaded by the Hamilton Chamber of Commerce that documented the potential of harvesting residential thermal energy from Hamilton’s Bayfront Industrial Area. The report concluded that there is enough residual energy to heat more than 48,000 homes in downtown Hamilton and the surrounding area.

Energy Harvesting Feasibility Study

In March 2023, HCE launched a year-long study that will dive into the technical feasibility and commercial viability of harvesting residual thermal energy from Hamilton’s Industrial Bayfront as a source of heating for all types of buildings, new and old.

Canada’s Thermal Corridor

HCE is leading a visionary exploration of a thermal corridor fuelled by residual energy that would serve buildings across the GHTA with low-carbon heating solutions.

Energy Harvesting Feasibility Study 

A guiding principle for this Study is the end goal of developing a scalable model for low-carbon building heating that can be replicated in other jurisdictions. A fundamental success factor will be involving investors, manufacturers, policymakers, carbon reduction specialists, and other subject matter experts in our journey.
