GES provided mechanical, electrical, plumbing, and fire protection engineering services for the modernization and 30,000 sf addition to an elementary school. The new design includes two classrooms per grade, resources rooms, areas for art and music, a science lab, media center/computer lab, dining facility/kitchen, and office and administration spaces. Prior to starting work on the design, GES developed a life cycle cost analysis and energy model to determine the options for the HVAC system.  By selecting a variable refrigerant flow (VRF/VRV) system, DCPS was able to save money up-front over an equivalent typical system, while providing heating and cooling in various spaces simultaneously.
