Passive House Pulse Toronto – Passive House and Mechanical Engineering: Best Practices for Cooling, Ventilation & Heating

Wednesday, January 31st, 2024 – 5:30 – 7:30 pm EST | IN-PERSON
Introba – 380 Wellington St W, Toronto, ON M5V 1E3

Optimized mechanical systems are a critical component of any successful Passive House project. This is particularly true in challenging climates such as Ontario’s, where buildings experience extreme conditions during both the heating and cooling seasons. Design teams operating without this understanding can find meeting Passive House performance levels to be a challenge when it comes time to integrate the mechanical design with a high-performance building envelope. Join our panel of mechanical experts as they discuss the apparent gaps that arise between mechanical engineers and the wider design team and how teams can deliver Passive House outcomes, more easily. Topics related to heating system selection, cooling system sizing, and ventilation best-practices will be discussed. Key points for each topic will be presented by each panelist, and the audience will have an opportunity to pose questions to the panel.

Our panelists are the following:

Jamie Fine | RWDI

Jamie Fine | Senior Energy Consultant, RWDI

Jamie is Senior Energy Consultant at RWDI based in the Toronto office. He focuses on applying customized analysis techniques and tailored system performance assessments throughout the building lifecycle. He analyzes new and existing buildings through the detailed simulation of energy use, thermal energy demand, greenhouse gas emissions, and building air flow. Jamie specializes in translating real-world systems to computer models and implementing on-site testing across a variety of facility types. He has a background in research and consulting, and implements software including IES-VE, TRNSYS, CONTAM, and develops custom algorithms for design optimization, performance simulation, and energy code assessment. Jamie also develops custom workshops to support leaders, project managers, and key project stakeholders as they work through the building design process.


Cara Sloat | Hammerschlag & Joffe Inc.

Cara Sloat | Principal, Hammerschlag & Joffe Inc.

Cara Sloat is a Toronto-based mechanical engineer and principal at Hammershlag and Joffe, a 100 person M&E firm serving projects across Canada. She brings more than 20 years of mechanical design experience to her clients and their projects, including design of mechanical systems for the 19-story Ken Soble Tower Transformation in Hamilton, the first Passive House retrofit of existing residential tower in North America. Cara focuses on commercial building design with a specific focus on low-energy decarbonized multi-unit residential and commercial buildings. Cara also serves on the board of Toronto’s 2030 District and is a UWaterloo alumni.


Jamie Dabner | Introba

Jamie Dabner | Principal, Introba

Jamie Dabner has a breadth of experience in all levels of Mechanical Consulting Engineering across multiple Canadian climates. Jamie received LEED accreditation in 2002 and has designed a multitude of low-carbon building typologies. He has contributed to the growth of Introba’s Sustainability Practice by leveraging his hard-won experience to impact a larger number of projects in their formative stages. As a key member of the Canadian Sustainability Leadership team, Jamie is involved in all facets of business and strategic operations. His wide range of experience covers policy projects, sustainability master planning, zero carbon, passive house, living building challenge, well buildings, pre-fabrication, offshore islands, net zero, low energy, closed and open geo-exchange systems, design analytics, renewable energy systems, life cycle cost analysis, design-build, and acting as a prime consultant.


Learning Objectives:
