Air Source Heat Pumps in Alberta: What Actually Works and What the Numbers Tell
Workshop Session
Air-source heat pumps are promoted as a highly energy-efficient, low-carbon solution capable of reducing operating costs, yet their performance in Alberta’s cold climate remains debated. This session explores design approaches that actually work, and the math that supports them. Drawing on real-world experience, manufacturer perspectives, and performance modeling, we examine cold-weather operating limits and performance implications, including impacts on cost and carbon emissions.
Through discussion and audience engagement, participants will gain practical insight into how air-source heat pumps can be effectively applied in cold climates.
Andrej Simjanov
Andrej Simjanov, P.Eng. is part of the High-Performance Buildings team at Remedy Engineering, where he works on mechanical systems design, energy modelling, commissioning, integrated systems testing, and building performance optimization. His work focuses on helping commercial and institutional buildings perform as intended, with particular emphasis on practical low-carbon design, HVAC system integration, operational performance, and the gap between design intent and real-world operation. Andrej brings a balanced, evidence-based perspective to building decarbonization, combining technical analysis with an understanding of cost, constructability, controls, commissioning, and long-term operation.
