See Passive House Features from TeamMTL’s Entry in the 2018 Solar Decathlon

The TeamMTL entry had two key requirements, which Ecocor’s panelized system easily met. The first requirement was to meet or exceed Passive House standards. The second requirement was the ability to quickly assemble and disassemble the shell.

This animation created by TeamMTL for their entry in the 2018 Solar Decathlon illustrates the unique features found in a Passive House by Ecocor: super insulated air-tight walls, ceilings and floors, a heat recovery ventilator system, high performance windows, solar gain, abundant natural light, and natural ventilation.

We arrived on Concordia's Loyola campus in early June. It took just five days to help TeamMTL assemble the shell of their Deep Performance Dwelling row house. Once assembled they prepared their entry for the competition.

In early November, our team returned to Concordia's Loyola campus and helped disassemble the shell in just three days, so it could be stored over the winter. Come spring of 2018, the panels and other elements will be taken out of storage and shipped by train to Vancouver. The panels will then travel by boat to Dezhou, China for the competition, which opens in July of 2018. TeamMTL will re-assemble their innovative, net zero, healthy living Deep Performance Dwelling row-house to vie against 21 other teams from 11 countries representing 43 Universities.

TeamMTL is made up of faculty and students from McGill and Concordia University in Montreal, Canada. They come from a diverse range of departments including: architecture, design and computation arts, engineering, business, management, as well as dance and theatre. Learn more about this project at

Ecocor is proud to have been chosen by TeamMTL for this worldwide competition. This project is a wonderful demonstration, of how Ecocor’s Passive House certified, panelized shell system shortens framing timelines. Ecocor offers a finished product on budget and on-time with fewer weather delays than traditional building methods.

Ecocor’s mission is to improve the construction process for homeowners, builders and architects - meet Passive House standards - and provide comfortable, durable and eco-friendly homes.
