New sustainability terms and concepts will affect roofing projects

As the sustainability movement grows, construction projects are becoming more complex. An unfortunate reality of this complexity is the documentation required to demonstrate compliance with various requirements common to projects with sustainable and/or high-performance goals. Voluntary points-based programs such as Green Globes,® LEED® and RoofPoint™ have terms and concepts that may be foreign to many in the construction industry—especially those working on one of these project types for the first time.

In addition, the most recent codes and standards, such as the International Energy Conservation Code® (IECC), International Green Construction Code (IgCC), 2012 Edition, ASHRAE 90.1-2010, "Energy Standard for Buildings Except Low-Rise Residential Buildings," and ASHRAE 189.1-2011, "Standard for the Design of High-Performance Green Buildings," also often contain unfamiliar terms and concepts.

To assist you when working within this new framework, following are some sustainable terms and concepts with which you should become familiar, as well as an explanation why they may be encountered.
