The Ontario Public Works Association is pleased to continue with our 2021 webinar series. 

Using Geothermal Energy to Reduce Heating and Cooling Costs  

Wednesday, February 24th, 2021
 12:00 pm to 1:00 pm EST

The presentation will provide an overview of the basics of geothermal energy as a way to potentially save on heating and cooling costs.  Rob’s presentation will look at the basic concepts, where geothermal may be used, potential payback periods and costs, and provide an example of a building retrofit. 
Rob will talk about the major physical systems for both below and above ground components of geothermal energy.  Rob will explain the significant importance of thermal balancing or Seasonal Thermal Energy Storage (STES), which has been demonstrated in Europe for decades and is fundamental to both improved efficiency and long term sustainability.  The subsurface storage of cool, 2-3oC  groundwater has been utilized in a chiller retrofit scenario to totally eliminate the new chiller system installation.  Rob will provide an example is provided where this retrofit concept using only cool groundwater reduced O&M costs by approximately 90%.  Rob will also provide an example of a large open loop heating and cooling system geothermal system retrofit for the 40 000 square metre Winnipeg IKEA facility. More recent technology such as horizontal  directionally drilling to develop horizontal wells is presented as an technique to increase subsurface heat flows in order to improve both open and closed loop geothermal systems efficiencies.

Speaker BIO's
Rob Sinclair
Mr. Sinclair has over 45 years of experience in hydrogeology, geothermal systems, soil remediation, water waste water treatment systems and solid waste management. Currently, he is a senior technical advisor to the Environmental Department at KGS Group, where he previously served as the manager of Environmental Services, and was responsible for environmental engineering services for the Winnipeg, Thunder Bay, and Regina offices of KGS Group. Prior to his time at KGS Group, Mr. Sinclair worked with Golder and Associates in Ottawa as a senior hydrogeologist in the early 1990’s. Mr. Sinclair has also had significant experience training students to manage and operate water treatment plants in Canada as well as a in Kenya, where he was the Department Head for Water Technology at Western College in Kakamega, Kenya in 1987 to 1989, which followed his time as the Department Head for Water Resources Engineering Technology at the Kelsey Institute in Saskatoon. Mr. Sinclair holds a Bachelor of Science in Geological Engineering from the University of Manitoba, a Master’s of Science in Hydrogeology from the University of Waterloo and Master’s of Science in Environmental Engineering for the University of Manitoba.
