In fact, the newest draft version of LEED (LEED v4) debuting at this month’s Greenbuild convention in San Francisco may go a long way to counter such misconceptions. It’s not that LEED v4 addresses the issue directly, but a dramatic increase in the complexity of the LEED system itself will make it much more difficult for building owners to jump to oversimplified conclusions. As an example, if you’re worried that too many building owners only look to roof reflectivity to identify a “LEED roof,” take a look at the new and very complex formula in LEED v4 for evaluating cool roofs shown in Figure 1.

Given the relative low state of math skills in our country, the answer to the question “Is this a LEED roof?” now may become “Huh?” All kidding aside, this example illustrates how as the LEED program grows and matures, it may become far too complex for oversimplifications like the mythical LEED roof. And in the long run that will be a good thing for the roofing industry because it will allow us to set new and better standards for identifying sustainable roof systems.

An alternative approach to answering “Is this a LEED roof?” can be found in the RoofPoint sustainable roof rating system developed by the Center for Environmental Innovation in Roofing. This innovative roof rating tool (mentioned in several previous columns this year) offers a comprehensive approach to sustainable roofing, but with a straightforward checklist that is easy to understand and apply. Instead of overemphasizing a single concept such as roof reflectivity, the RoofPoint system helps building owners and roofing professionals make the best decisions for sustainable roofs by focusing on all key aspects of sustainability from achieving efficiency in energy and materials to optimizing useful service life. And the RoofPoint evaluation checklist now can be completed using a simple web-based application available at the RoofPoint website (www.RoofPoint.org).

Growing market interest in RoofPoint also suggests that it can help fill the gap left by the increased complexity of LEED. In fact, new RoofPoint project applications are arriving at the Center every week, and it looks like the Center’s original goal of 100 new RoofPoint projects during 2012 will be more than doubled due to an outpouring of support from roofing contractors across the country.

So, between the growing complexity of LEED and the emergence of useful sustainable roof rating systems like RoofPoint, maybe the question “Is this a LEED roof?” will become a new and better question, “Is this a sustainable roof?”
