Abstract: Designing to improve infrastructure resiliency aims to provide essential services such as heating, cooling, lighting and plug-loads during extended power outages which may be caused from disruptive regional climate events or chronic stressors. Using a multi-objective approach (energy, cost and resiliency indicators), a methodology is presented to optimize annual operation indicators and event-specific performance indicators using a high performance building case-study. To exemplify the methodology, an ice-storm similar to the 1998 Eastern Ontario event leading to an electrical-grid outage for 48 hours. Results show that it is advantageous to strive for more air-tight and well insulated envelopes, beyond what is considered optimal for annual design performance, while utilizing renewable energy and storage system to ride-out events. Value of lost load calculations shows that payback of key technologies, such as electrical storage using batteries, can be reduced by over 10 years by considering climate change events in the design process.
