During a Webinar April 22, representatives from the DOE, Oak Ridge National Laboratory, and Lawrence Berkley National Laboratory, among others, launched a Roofing Savings Calculator designed to make it simple for consumers, contractors, and other entities to determine the potential energy savings of installing a cool roof.
The calculator is based on DOE-2, a well-established software program that analyses a building’s energy use. Because that FORTRAN-based system is geared toward engineers, the collaborators’ goal for the Roof Savings Calculator was to provide a user-friendly, Web-based interface that any layman could use.
To calculate the energy savings of replacing an existing roof with a cool roof, users simply answer a series of questions about the home, including location, square footage, heating system efficiency, and attic insulation, as well as information regarding the proposed replacement roof; “simple” and “advanced” modes are offered depending on the knowledge level of the user and some questions provide links to additional explanation and information.
Upon completing the questions, the user receives a calculation of potential yearly and monthly savings. Results also can be emailed.
The Roof Savings Calculator can be found at www.roofcalc.com. –Katy Tomasulo
