Since the construction of the Living City Lab – Archetype Sustainable House at The Living City Campus in 2008, a number of manufacturing companies and distributors have partnered with the Toronto Region Conservation’s (TRCA) Sustainable Technologies Evaluation Program (STEP) to demonstrate and conduct research on new, innovative sustainable building products and designs.

In the wake of rising energy costs and concerns over the effects of greenhouse gas emissions, specific research was conducted focusing on new technologies designed to help improve energy efficiency and lower carbon emissions.

Here is a look back at Mitsubishi Electric Sales Canada Inc.’s participation in a study conducted by students from Ryerson University’s Mechanical Engineering Department and members of STEP.

With the donation of the Zuba-Central® air source heat pump by Mitsubishi Electric Sales Canada Inc., research conducted evaluated its overall performance over a heating and cooling season, and its cost effectiveness within a cold climate setting (Woodbridge, Ontario) versus a ground source heating pump.

“Mitsubishi Electric Sales Canada Inc. was pleased with the partnership we established with TRCA and STEP,” said Clive Carr, Residential Sales Manager (HVAC Product Sales), Mitsubishi Electric Sales Canada Inc.  “This partnership allowed us the opportunity to evaluate our new technologies in real life applications outside of our standard laboratory testing, and have provided us with feedback on customer demands.”

Based on the overall findings, the technical brief provided key findings for Mitsubishi Electric Sales Canada Inc. that could be used to market the Zuba-Central® unit and provided third party evaluation that could be shared with consumers. Results concluded favorably for Mitsubishi Electric Sales Canada Inc., as the unit was proven to exceed manufacturer and EnerGuide performance ratings while maintaining high performance ratings at cold temperatures.

Environmental benefits, such as greenhouse gas emission savings, were also observed through the research.Today, the Zuba-Central® air system can be found installed in many residential homes and commercial developments as an alternative to traditional heating and cooling systems as developers look to meet new, more environmentally-friendly building standards.

Carr further added, “We have benefitted from the case study completed in that the case study provided a comparison to a ground source heat pump, and served as a reference to the engineering community, and end users evaluating the purchase of our air source heat pumps.  Ontario utility companies were able to use this info to assist with their rebate programs, and the benefits air source heat pumps would have on their conservation demand management (CDM) programs.”

The relationship developed between STEP, Mitsubishi Electric Sales Canada Inc. and Ryerson University has led to opportunities for other systems and technologies to be installed and tested, utilizing existing equipment and monitoring infrastructure.

The Living City Campus, provides a test bed with instrumentation and technology to promote the adoption products to the Canadian marketplace.To read the complete technical brief, visit
