The improvements involved major electrical, mechanical, and lighting systems. The scope of Siemens’ work on the project included energy-efficiency audits of all facilities, HVAC equipment retrofits and replacements, enhancements to a building automation system, lighting retrofits, and upgraded electrical systems that include power monitoring.
During the construction period, energy usage dropped 30 percent beyond early projections, according to Greg Warner, district performance assurance manager for Siemens. About 84 percent of all utility savings have been derived from electricity, with about 16 percent in gas and water.
