1. Design of a Resilient, Ultra-Low Energy Built Environment with Deep Integration of Renewables in 2050 - challenges and opportunities Andreas Athienitis, Eng., PhD, FCAE, FIBPSA, FASHRAE NSERC/Hydro-Qu bec Industrial Chair & Concordia University Research Chair Director and Professor, Concordia Centre for Zero Energy Building Studies (CZEBS) aathieni@encs.concordia.ca Energy resilience: Ability of a community to generate its own energy for critical periods and emergencies icestorms, floods, pandemics Ice-storm 98, 4.7 million people displaced, $6.4 B loss Varennes Library, Canada s first institutional net-zero energy building

2. How can Canada achieve Resilience + Sustainability + Innovation Major challenges Decarbonization of the built environment by 2050; we spend over 90% of our time indoors Design of buildings and communities for resilience and a high quality of life, suited to protecting people during emergencies, including pandemics (ventilation etc) Design of the built environment for flexibility and safety of all groups (including elderly, kids, disabled) Complexity: Need for Transversal Innovation, integration of novel renewable energy technologies, building technologies, mobility technologies, smart technologies and energy grids Major opportunities More than half of buildings will be new by 2050; rest will undergo deep retrofits Massive construction projects with emphasis on cross-cutting transversal integration and innovation across energy, construction, manufacturing and public health + wellbeing Planning for partial teleworking can aid in more flexible work schedules for families and reduction in transportation emissions Can public sectors take the lead with emphasis on high risk high reward transversal innovation? in close collaboration with universities and industries? Innovative urban planning approaches to zoning, density and technology adoption

3. Single-goal approaches vs transversal integrated approaches Most government programs for technology development/adoption tend to focus on single-sector easy-to-explain approaches (such as decarbonization by itself); industry and cities tend to adapt to this approach Increasingly we are dealing with complex strongly linked issues such as built environment design for decarbonization + resilience + wellbeing + health An integrated approach is followed in the Canadian Academy of Engineering Roadmap to Resilient, Ultra-Low Energy Built Environment with Deep Integration of Renewables in 2050 https://cae-acg.ca/projects/resilient-infrastructure-project/ Photovoltaic/thermal 2008, 2009 West5 community London Ont.
