1.5 ConEd Learning Hours
4:00 p.m. ‐ 5:30 p.m.
Existing building retrofits are a key strategy for achieving OAA’s mandate for climate action. Aging buildings with deferred capital means that many existing buildings are excellent candidates for deep retrofits that significantly reduce carbon emissions, address safety and performance issues, mitigate overheating, improve comfort, and increase resident satisfaction. This session will focus on strategies for assessing existing buildings for their retrofit potential, aligning deferred capital with opportunistic upgrades, and implementing complex decarbonization projects on occupied multi‐unit residential buildings.
The session will leverage experience from several deep retrofit projects progressing through the study, design, and implementation stages. We will use project references to explore topics such as portfolio planning, decarbonized capital planning, electrical service constraints, managing tenant expectations, enclosure and HVAC decarbonization options, embodied carbon, and the phasing of complex enclosure and HVAC projects.
Learning Objectives
1. Understand the existing building challenge and the retrofit opportunity.
2. Understand how to prioritize retrofits.
3. Understand the practice of decarbonized capital planning.
4. Understand how to implement complex retrofits on existing buildings.
Scott Armstrong, BSS, CET, LEED AP
Scott Armstrong is passionate about buildings and often speaks publicly about their design and construction, ongoing performance, deterioration and failure, opportunities for decarbonization and retrofit, and their renewal. His expertise is diverse and includes facade systems and cladding, decarbonization, the science and art of building enclosures, roofs and vegetated roofs, building retrofits and renewal, sustainable services, and integrated design facilitation for new and existing buildings. Scott’s project experience includes commercial, institutional, heritage, recreational, mid‐ and high‐rise residential, and neighbourhood developments in Canada, the Caribbean, and the Middle East. 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.
