Advanced Lighting Controls for Reducing Energy Use and Cost at DoD Installations
EW-201012
Objective
The primary objective of this project is to quantify the energy, environmental, and economic benefits of deploying advanced lighting control technologies at a representative U.S. Army installation (Fort Irwin). Cutting-edge integrated lighting control strategies—scheduling, personalized dimming, daylight harvesting, and occupancy sensing—will be implemented. The system solutions deployed will be specifically tailored to suit the unique characteristics of the respective target facility. Empirical evidence will be gathered to substantiate potential energy savings, payback time, system reliability, and user satisfaction as a result of deploying these systems, and the results will be extrapolated to estimate DoD benefits more broadly.
Technology Description
Several advanced lighting control technologies will be applied in the form of three systems: Hybrid ILDC (Integrated Lighting and Daylight Control), OccuSwitch Wireless (previously called the Wireless Actilume), and Wired PNLCS (Philips Networked Lighting Control System-previously called the LMM System). These systems meet different DoD facility requirements, offer unique cost-benefit advantages, and feature scalability in coverage, function, and life cycle.
* Hybrid ILDC is a building-wide networked system that maximizes the use of daylight while improving user comfort through integrated control of electric lights and motorized blinds. The system features wireless connectivity among sensors and actuators within a zone and exploits wired connectivity across zones to enable building-wide deployment and monitoring.
* OccuSwitch Wireless is a room-based lighting control system, which reaps energy savings through occupancy sensing, dimming, and daylight integration.
* Wired PNLCS is a building-wide wired lighting control system offering scene settings, personalized dimming, scheduling, occupancy sensing, daylight harvesting, distributed control, and interfaces with existing building management systems including HVAC.
While all three systems are designed to optimize lighting-related energy consumption resulting in considerable energy savings, the Hybrid ILDC system with its innovative multivariate integrated control will also reduce HVAC cooling load, thereby providing additional energy savings. The exact amount of energy savings will depend on building type, climate conditions, and user preferences, and the degree of success will be determined by the integral energy savings combined with user comfort and ease of use. This project has targeted a 50% reduction in lighting-related Energy Use Intensity (EUI) (kWhr/sq.ft./yr) for the demonstration.
Benefits
The potential DoD energy-related cost savings achievable through widespread deployment of these lighting control technologies are estimated at $300M per year, based on a 50% reduction in energy use and the current energy expense of $600M per year for lighting. Intangible benefits such as enhanced productivity and comfort level of the building occupants will be realized as well. Expected payback time of the required investment can be between 2 and 7 years depending on the specifics of the building, lighting energy usage pattern, and the location. Additionally, DoD will gain familiarity with an array of advanced lighting control solutions that can be deployed throughout most of its installations (2 billion sq. ft. of buildings) regardless of building age, configuration, or location, and will obtain the energy reporting capabilities to manage energy costs across facilities.
