Energy Performance Monitoring and Optimization System for DoD Campuses
Abstract
The United Technologies Research Center (UTRC), with sponsorship from the U.S. Department of Defense (DoD) Environmental Security Technology Certification Program (ESTCP) for Energy and Water, conducted a demonstration of the Energy Performance and Monitoring Optimization (EPMO) system prototype used to improve the energy efficiency of both heating and cooling systems. The EPMO system was implemented in this demonstration project as an extension of the existing Building Management Systems (BMS) for optimization of control schedules, energy performance visualization and system diagnostics for building and district heating systems. The system was demonstrated in two buildings at Navy Recruit Training Center in Great Lakes, Illinois, during the 2012-2013 heating season for three air handling units (AHU) and 54 terminal units. The EPMO system integrates optimal control algorithms with system performance monitoring, diagnostic and visualization tools. The control algorithms use weather forecast data, zone sensor data, meter data and information from the AHUs and terminal units to generate optimal control schedules. For example, an optimal control schedule can control the discharge air temperature values to minimize energy consumption while meeting comfort constraints. The EPMO diagnostics tool uses the sensor and meter data to detect and isolate equipment faults, such as stuck dampers or valves, to prioritize the fault correction based on energy impact. The EPMO visualization tool continuously displays the diagnostics information to facilitate understanding the equipment fault impacts on energy consumption. The main technical objectives of the demonstration for energy savings and system robustness were met.
