What the mechanical contractor needs to know about the new building envelopes and how they affect the work we do. Discussion is on the changing regulatory and policy context that is driving changes in building enclosures and cascading effects on design and construction practices. What will these changes mean for mechanical systems design and installation? Topics include operating and embodied carbon emissions, performance metrics, Step 5 - airtight and low-thermal demand buildings, emerging building science risks and mitigation strategies, etc.
Presented by: Nico Pellegrino - Technical Specialist, Thermo 2000
Topics covered in this video include:
- Do I need a buffer tank with a heat pump system?
- Do I need a back up system for a heat pump system?
- The different ways to utilize a buffer tank heating or cooling
- Do I need full back up or just to get me some heat?
- What is the trend for buffer tanks and electric back up boilers for heat pump systems?

Presented by Jeremy Young, TECA Board Member and Quality First Instructor
Jeremy Young presents an overview of currently available technologies for residential hydronic heating, chilled water cooling and domestic hot water using air-source heat pumps. The presentation includes details on suitable applications, strategies to enhance efficiency and reliability, as well as defining the common mistakes made by experienced designers and installers who come from backgrounds with fossil-fuel based hydronic heat sources and how to mitigate those risks.
Scott Miller, Director of TECA (Thermal Environmental Comfort Association of BC) discusses heat pumps in this presentation.
