Power Wise at Work: Mohammed Schools of Atlanta
Last month, GIPL visited Mohammed Schools of Atlanta, a Muslim school in south DeKalb county that provides a Qur'anic-based education for children from preschool through high school. Mohammed Schools signed up for an energy audit through our Green Mosque Initiative — through December 2015, all Muslim mosques, schools and prayer centers are eligible to receive a free energy audit through GIPL’s Power Wise program and the Community Foundation’s One Region Atlanta program.Engineer Gary Gabriels, PE, CEM and LEED-AP, was on hand to walk us and Principal Qur’an Shakir through the audit, giving us a tour of the school's buildings. Mohammed Schools is housed in a combination of older and newer buildings -- one built in 1970, and another built in 2001. Altogether, the school pays to heat, cool, and light approximately 12,000 square feet. This audit revealed a potential $5,800 in annual energy savings for the school. Here are the finer points of Gary's findings:The focus of an energy audit is typically on heating and cooling costs, since a shift toward more sustainable systems and practices in that arena makes the biggest impact on a community's energy bills. Gary explained the benefits of investing in a wifi thermostat system, where energy savings is achieved by more precise temperature control, better setpoint management (especially during unoccupied heating hours), and better management of time of day scheduling. He estimated that Mohammed Schools could save 5% on their energy bills with this change alone.We also looked at the school's light fixtures. Most of the classrooms and hallways are illuminated by 2’x4’ four lamp light fixtures that use T12 lamps. Gary estimates that if each fixture were replaced with a new T8 light fixture the energy consumption would be reduced by 45% while the lighting output would be reduced by 31%. This would save the school $1,302 annually.Energy loss was another key factor Gary investigated. He identified several spots around windows and sliding glasss doors where massive air leaks could be plugged. Mohammed Schools has a beautiful, lofted setting for their Musallah, but the walls are thin and not well insulated. Gary recommended EIFS (Exterior Insulation Finishing System) on the indoor surface of the roof decking. EIFS includes a two-inch thick layer of insulation.In addition, he recommended the six skylights be covered with solar window film to prevent "hot spots" in the room from sunlight. Gary suggested several other changes and tips for Mohammed Schools as they tackle energy efficiency projects in the coming months and years:
