The need to address sustainability in the built environment is being accelerated by external concerns. Some of these are environmental and resource issues, rising energy prices, climate change, indoor environmental quality, international pressure, energy security, and natural disasters that seem to be happening more frequently than ever before. Sustainability focuses on the distant future. Resiliency focuses more on the present, e.g. How do we keep our buildings functioning during floods, long power outages, or protect building occupants from smoke and odors during wildfires?
