Presentation Title:

Geothermal Exchange Explained: A Renewable Heating and Cooling Solution on the Path to Net Zero


The building sector is a significant contributor to greenhouse gas emissions, contributing up to 66% of energy-related carbon emissions in urban centres. As governments enact new policies on the path to Net Zero by 2050, the building industry is shifting to green technologies and renewable energy resources.
We will examine how geothermal exchange operates as a heating and cooling sustainable system that uses the Earth as a both a heat source and heat sink. The geothermal exchange system is a solution that significantly reduces carbon emitting equipment thereby contributing to a building’s Net Zero design.


Matthew is a professional engineer who works with Subterra Renewables, a renewable energy developer who designs, builds, owns, and operates geothermal heating and cooling systems across North America, with the goal of significantly reducing greenhouse gas emissions and ultimately reaching Net-Zero building operation. Previously he has worked with design firms to develop strategies for building energy and carbon emission reduction for new and existing buildings. Matthew holds a master’s degree in Building Science from Ryerson University, where he is now a Sessional Instructor, and sits on the CaGBC’s Zero Carbon Building Standard Steering Committee.
