This webinar features lessons from the trenches of real projects, particularly www.west5.ca and www.evepark.ca in London, Ontario, Canada: a 70 acre mixed use site (2.5M sq.ft. incl. 2,000 homes and 500k sq.ft. of commercial / retail) partially built out, and on track to achieve net-zero energy at the community level. This presentation summarizes the present status, demonstrates that net-zero is feasible in today's market at scale, and shares some of the lessons learned thus far.

Lessons Learned:
• Excessive red tape (starting @ 2ndary plan)
• “Plan early” = soooo many meetings…
• Design for Simplicity (eg: stacked/b2b challenges,
reduce corners, optimize layouts, prioritize low o&m
and long-life items)
• Beware over-engineering: thermally broken balconies /
view dynamic glass
• Bundled IRR, not segregated simple paybacks
• Monitoring matters (especially @rental/condo)

23. Questions?
Feel free to ask about:
• Lessons learned
• The permitting process
• Technology v. finance v. policy
• How we promoted culture change within Sifton
• The impact of COVID shutdowns
• The labour shortage
• Affordability
• How this all affects policy opportunities (carrot v. stick)
