CONTROL PANEL isn't the only way to get LEED points. "You could also use ENERGY STAR products," explains Dr. Dru Crawley, FASHRAE, director, Building Performance, Bentley Systems, Inc. "I see schools who want to achieve a LEED rating doing a 50/50 split with half going for ENERGY STAR prod- ucts and the other half investing in energy modeling." While both systems lead to a more effi cient building, using ENERGY STAR products compares your structure to other equivalent ones while energy modeling takes a detailed snapshot of the actual building. It can predict how that build- ing will perform and allow users to make informed decisions on which mechanical and electrical systems to buy. "A robust energy model can weigh various design op- tions in a way that other tools cannot, and it can supplement other decision criteria. Running a variety of models allows one to not only test feasibility, but to make informed cost-benefi t analyses of various design options during any stage in the design process," according to the Energy Modeling Guide. Meeting Codes and Expectations In some circumstances, modeling is the only way to go. "Places that have stringent energy requirements, like California, practically require energy modeling to meet the codes," says Dr. Crawley. "For the rest of the country it really is LEED that is pushing the technology. Schools know that students care about LEED, so they are catering to their customers." "Campuses present a special opportu- performance sloan white also comes in A full line of vitreous fixtures engineered and built exclusively for commercial use Maximum performance at any flush volume The perfect partner to our industry leading flushometers and faucets From the leader of energy- and water- efficient commercial restroom solutions Scan with Smart Phone for more information nity when it comes to energy modeling," continues Coreina Chan, consultant, build- ing practice, Rocky Mountain Institute. "You have hundreds of buildings that complement each other in load, shape, and use. If you know what the buildings are consuming you can introduce simplicity to your central plant." With all of these advantages, the use of energy modeling is growing. With that growth comes some pains. Surpris- ingly, price isn't one of the major issues. "Modeling is not that expensive, but energy costs are still low so some clients don't want to invest in the technology," says Dr. Crawley. While it is hard to put a dollar-per-square-foot number on the process, Dr. Franconi estimates that, "a small building might run $10-15,000 dol- lars to model while a larger, more complex structure could go as high as $75,000." However, you get what you pay for. "The deeper you go with modeling, the bigger the potential savings," she concludes. 20 COLLEGE PLANNING & MANAGEMENT / AUGUST 2012 WWW.PLANNING4EDUCATION.COM
