that design, construction and startup of all equipment results in a facility that is achieving the owner's stated project re- quirements upon initial occupancy. Here's where monitoring-based com- missioning takes over. Even the most technologically sophisticated facilities will experience equipment variables that result in diminished energy ef ciency. The reasons why buildings typically do not perform as planned might include poor control of chilled water distribution to air handlers, badly sequenced chiller operation or poor VAV zone control. The ability to verify performance and design intent on a regular basis, and immediately correct inef ciencies, presents an ef ective way of keeping a building's long-term energy use on track. This is especially signifi cant in a campus setting, where utilities are system-critical and dif erent buildings run on multiple power sources with chiller plants that need to be inte- grated ef ectively. Taking holistic view of energy performance This was the case with a recent program of continuous energy oversight for the chiller, boiler and cogeneration plants at the Newark, New Jersey campus of Rutgers Biomedical and Health Sciences, which has resulted in $1,155,000 in sav- ings in its fi rst two years of operation. The RBHS facility is a district energy plant that provides utilities to six buildings at RBHS, including University Hospital of Newark, comprising a total of 2.2 million square feet of research, academic and healthcare facilities. The plant and outlying buildings had been retrofi tted with new energy-ef cient equipment to provide the energy plants with the equipment and redundancy needed to help assure reliability for the next 10 years. As part of the capital improvement project, a central plant monitoring system at the facility was designed and implemented by utiliVisor. The system monitors 824 data points, including all operations equipment at the plants. A program of continuous energy oversight was implemented for the 20,700 ton chilled water plant, 291,000-pounds- per-hour boiler plant and 10.5 megawatt cogeneration system, along with all ancil- lary equipment. The monitoring program involved continuously commissioning energy plant operations to maximize the payback of the retrofi t to the university. The ef ort took a holistic view of energy performance, analyzing the operation of each piece of equipment required to generate and distribute chilled water, high-temperature hot water and electric power to the campus. The web-based, networked energy oversight system works in real time to collect and format data from the new chiller plant components. The data is used to compare actual chiller plant operations against design-ef ciency benchmarks and identify equipment errors, communicating alerts by email to energy plant operators and facility managers. Steps to improve performance are recommended and the cost savings are calculated. The chiller plant monitoring and analysis tools are also available to plant operations and facility management staf over a secure website, which is accessible from any location using a desktop PC or mobile device. The utiliVisor engineers are respon- sible for analyzing real-time energy data from the facility and recommending the most ef cient operating strategy at all- load conditions as the conditions change. The data analysis enables the equipment to be fully optimized on an ongoing basis, resulting in substantial energy and cost savings. A recent study prepared for the California Energy Commission by Lawrence Berkeley National Laboratory stated: "On a portfolio basis we fi nd MBCx to be a highly cost-ef ective means of obtaining signifi cant portfolio/program- level energy savings across a variety of building types. MBCx helped identify a very wide range of defi ciencies. Anecdotal evidence shows the value of monitoring in identifying savings opportunities that would not otherwise have been identifi ed." Remote energy monitoring of ers a cost-ef ective means for healthcare organizations to realize greater energy ef ciencies and lower operating costs over the lifecycle of a building. Monitoring of ers an important risk-management strategy that leads to verifi able and durable energy-demand reductions. Timothy Angerame is chief operating of cer at utiliVisor.
