Enclosure Design and TEDI Targets. TGS, Zero Carbon, and PH

1.5 LEARNING HOURS

Location: Online
Provider: OAA

Time 11:00 AM – 12:30 PM



Webinar Description 

“Per cent better than the code” is a fading metric, giving rise to a new performance paradigm: thermal energy demand intensity (TEDI). Simply defined, TEDI is the measure of heating energy required to offset enclosure losses and to heat fresh ventilation air. Thus, enclosure performance is no longer subject to trade-offs with highly-efficient mechanical systems—it is paramount to achieving success. 

TEDI has been adopted as a compliance metric for the Toronto Green Standard (TGS) and CaGBC’s Zero Carbon Building (ZCB) program and has been a requirement of Passive House projects since inception. Coupled with the requirement to incorporate thermal bridging into whole-building thermal performance values, TEDI is changing the way we design and construct buildings.

This session will provide a background on TEDI, various step code and green building TEDI targets, prototypical enclosures to achieve TEDI targets, the impact of thermal bridging on whole-enclosure performance values, and design tools to help you meet your objectives.

Learning Objectives

  1. Obtain an overview of the TEDI metric and how it is measured.

  2. Develop an understanding of TEDI targets in the Toronto Green Standard (TGS) and CaGBC Zero Carbon Building program.

  3. Discuss approaches to Passive House design, including from PHI and PHIUS.

  4. Explore typical thermal bridging design conditions and effective thermal bridging report tools.

Speaker(s)

Scott R. Armstrong, Dipl Arch Tech, BSS, CET, LEED AP BD+C

Scott Armstrong is passionate about buildings: their design and construction, ongoing performance, deterioration and failure, and, ultimately, their renewal. His projects have spanned commercial, institutional, heritage, recreational, residential, and neighbourhood development in Canada, the Caribbean, and the Middle East. Scott brings 20 years of experience to WSP’s building science and sustainability projects with expertise in high-performance buildings, building enclosures, facades, existing building repair and renewal, roofing and green roofs, and integrated design. A LEED Accredited Professional, past-secretary and board member of the CaGBC Greater Toronto Chapter, a Building Science Specialist (BSS), and Certified Engineering Technologist (CET), Scott successfully bridges the traditional gap between architectural and engineering disciplines and is frequently invited to speak publicly on topics such as enclosure design, high-performance building design, and existing building retrofits.
