ThermalPoint Case Study 1
Prepared by The Sustainable Technologies Evaluation Program (STEP) March 2025 Contact: step@trca.ca Background The thermal balance point temperature (TBPT) is a key metric for sizing heat pumps. It represents the outdoor temperature at which a heat pump can no longer meet a home’s heating demand without supplemental heating. Graphically, the TBPT is the outdoor temperature […]

SWM Pond FAQ
What are your thoughts on life rings and life safety stations at these ponds? Answer Some municipalities adopt a standard policy. My opinion is it’s a judgment call per site and that if you see you have permanent pool, you see steep embankments for whatever reason, there you can make the call that there’s a […]
Case Study: Evaluating the performance of different winter maintenance products on permeable and conventional asphalt.
Background Credit Valley Conservation’s (CVC) head office is part of the Meadowvale Conservation Area, adjacent to the Credit River (Figure 1). During winter, salt is applied to the entrance driveway, parking lots, and sidewalks to keep staff and visitors safe and minimize slip and fall incidents. However, chloride (the main ingredient of winter salt) contaminates […]
