We focus on practical mechanical engineering and building-system solutions that balance performance, efficiency, comfort and constructability.
J&I Projects Inc. is positioned as a trusted engineering partner for building owners, architects, contractors and Projects teams. Our work emphasizes coordinated design, thoughtful problem solving and solutions that perform in the real world.
We believe good engineering should be understandable, practical and aligned with the Projects's goals.
Mechanical systems are considered as part of the whole building—not in isolation.
Careful engineering, coordination and documentation at every stage.
Solutions that consider energy use, lifecycle value and operational performance.
Clear communication and collaboration with every member of the Projects team.
We built a passive house in Toronto in 2019-2020. This type of house requires a specialized heating/cooling and ventilation design. Mentor was able develop a comprehensive plan for implementation for our home. The complexities of designing heating, ventilation and cooling (HVAC) systems for a passive house in Canada are related to the fact that these types of homes are new to the Canadian building industry. Mentor developed our HVAC plan investigating and discussing the potential components with suppliers. He analyzed air flow as well as, heating / cooling requirements to ensure the system operated according to Passive House Canada specifications. The plan involved integrating a heat pump, humidifier, HRV and the innovation of a HEPA filtration. Mentor was available for consultation as needed when the system was being installed and afterwards for any questions about operations. We appreciated Mentor’s engineering expertise and congeniality when working with us and our architect throughout the project. We are pleased with the comfort of our home and we highly recommend Mentor for complex projects like ours.
