Resiliency. Sustainability. These terms get tossed around a lot in the industry, especially when it comes to defining sustainable roofs. These terms, to most of us, are more nebulous than practical when it comes to buildings and roofing. Of course, dictionary definitions trend to the common uses of the words. Simply put, resilience is the ability to bounce back, and sustainability is the ability to continue over time.
ASTM Committee E60 on Sustainability developed standard E3341, General Principles of Resilience, which includes a definition of "resilience". It states: "resilience, n—the ability to prepare for anticipated hazards, adapt to changing conditions, to withstand and limit negative impacts due to events, and to return to intended functions/services within a specified time after a disruptive event." Also, E60 developed standard E2114, Terminology for Sustainability, which
defines sustainability as "the maintenance of ecosystem components and functions for future generations."
The dictionary and ASTM definitions are certainly correct, but, honestly, not all that helpful when it comes to designing a roof. So, how does one implement resiliency and sustainability when it comes to buildings, and specifically roof systems? The roof on a building is arguably one of the key elements required for a building to remain usable for long periods of time and after extreme weather events, i.e., sustainable and resilient. So, again, what does all this mean when it comes to designing roof systems?
In the author's opinion, the most sustainable roof is one that performs properly for a very long time, almost irrespective of materials choices. And the most resilient roof system is one that stays in place (think durability and wind resistance), provides efficient and effective thermal protection for the long term, and is usable if there is no power. Yes, these are simple and focused ideas, but they are very practical concepts that allow us to lay the foundation for design concepts that then can be translated
into roof system designs and construction details–all of which should be easily implemented. In other words, these simple and focused ideas allow us to discuss the nuts and bolts of roof design that results in a roof that is sustainable and resilient.
