INTECH MARCH/APRIL 2018 15 COVER STORY ity (e.g., geofencing—turning climate systems on or off depending on user distance from site—and learning user patterns of occupancy) is added. Commercial buildings The term "commercial building" is broad and can be applied to hospitals, hotels, offices, and even public spaces. These buildings are much more energy intensive than those in the residential sector and offer greater potential for cost-effective energy savings. The building management system (BMS) of large commercial buildings already generates significant volumes of data. However, previous genera - tions of BMSs were not designed to use this data to optimize building en - ergy performance. Continuous commissioning (CCx), also known as monitoring-based com- missioning (MBCx) or persistent com- missioning (PCx), uses the data gen- erated from a BMS to continuously identify potential energy-saving op- portunities. Using advanced "big data" analytics, persistent commissions reg- ularly report to the facilities manager to ensure that the elements of the site's energy-using equipment, normally HVAC equipment, are operating at optimal levels and that any deviations are investigated and acted upon. CCx/MBCx/PCx is a well-established service in the U.S., recognized as achieving savings between 10 and 20 percent. The service is valued by energy users, as it helps to significantly reduce costs of capital and operations. CCx/MBCx/PCx has not appeared in Gartner's hype cycle, because it was fi- nancially viable from the start at sites of sufficient size. The main advance- ment in the past few years is that ana- lytics have moved to the cloud, so CCx/ MBCx/PCx is viable for much smaller sites. Respectable returns on invest- ments (less than three years) can be achieved for energy consumption of less than U.S. $0.5 million. Networked public lighting: Lighting technology has experienced a revolution in recent years as LEDs replace tradi - tional light sources. Although the move from sodium and mercury vapor lamps to LED has been the source of major sav - ings, the nature of public lighting makes additional connectivity and control more financially attractive. Providing minimal light levels in unoccupied ar - eas as well as communicating mainte- nance information brings savings to sys- tem operators that are not available to residential customers. An independent global trial of LED technology in 12 of the world's largest cities found that while LEDs can generate energy savings of 50 percent, these savings reached more than 80 percent when LED lighting was coupled with smart controls. Process Traditional industrial energy manage- ment focuses on the efficient provision and use of process energy needs, such as heating, cooling, compressed air, and electricity. The IoT has a wealth of new data streams to support energy man - agement measures. Process industries may be slower to adopt some of these technologies than the consumer market due to a greater familiarity with the use of sensors and automation. A key driver for the digital transformation for the process industries is maintaining global competitiveness and technological ad - vances, therefore forcing the alignment of production and wider business pro - cesses through the tools that offer new possibilities for business models. Monitoring-led preventative mainte- nance, condition-based maintenance, and predictive maintenance To increase reliability and efficiency, and to gain other operating benefits, such as re - duced maintenance and improved safety, many refineries and process plants are turning to the IoT.
