Firm Description

Automated Building Systems and Osram Sylvania, Inc. design a solution to maximize energy savings, while maintaining a safe and appropriate environment for studies, at the J. Eugene Smith Library, Eastern Connecticut State University.

Public Act 11-80 required a 10-percent reduction in energy usage for state buildings by January 1, 2013. In order to achieve this goal, the Connecticut Department of Energy and Environmental Protection launched a new program entitled Lead By Example, the department’s first major energy initiative. The J. Eugene Smith Library of Eastern Connecticut State University was one of the first buildings selected to be upgraded for the Lead By Example program.

Built in 1998, the library consists of four floors totaling 130,449 sq. ft. The facility is open for approximately 91 hours during an average week, with occupancy exceeding 50 people at any given time. The J. Eugene Smith Library is heated and cooled year-round and occupancy can be random, varying with exams and school work. Facility managers were looking to maximize energy savings while maintaining a safe and appropriate environment for studies.

Addressing Energy-saving Challenges

Administrators with Eastern Connecticut State University worked with Automated Building Systems, Inc. to provide a solution. No single-energy savings strategy would be sufficient enough to meet the goals of Lead By Example, so Automated Building Systems specified the ENCELIUM Energy Management System (EMS) to meet the unique energy-saving challenges at the J. Eugene Smith Library. The ENCELIUM EMS is a sophisticated, all-encompassing solution that is capable of integrating six lighting energy management strategies to maximize savings.

Networked occupancy sensors were installed in the library to switch lights on/off based on motion detection. Task tuning was implemented throughout the space to decrease illumination levels by 30% to provide just the amount of light that is recommended for how the space is used, which also reduces eye strain for the library occupants. In stack areas that were not often used, the lighting system had been powered unnecessarily from early in the morning until late in the evening.

Time scheduling was employed to reduce the scheduled hours in these sections to match normal usage patterns. Outside of those hours, luminaires in these sections remain off unless occupancy is detected. Automated Building Systems further capitalized on energy-savings opportunities by integrating the library’s Alerton HVAC system with the ENCELIUM EMS time scheduling program. This integrated approach led to additional savings that would not be possible with a circuit-based control system. Complementary design strategies included daylight harvesting to reduce electric light in the presence of natural daylight.

Reducing Energy Consumption and Costs

Eastern Connecticut State University reduced the annual energy consumption for the J. Eugene Smith Library by an estimated 607,500 kWh eliminating the equivalent of 353,178 pounds of carbon dioxide per year. This translates to an estimated energy cost savings of $114,000 per year. The ENCELIUM EMS allows lighting to be dimmed down and HVAC turned off in rooms and areas that are not in use during scheduled hours.

Energy consumption was reduced by 20 percent versus the same month of the prior year with the installation of the ENCELIUM EMS. These substantial savings will allow the ENCELIUM system to pay for itself in just over six years.

About the ENCELIUM Energy Management System

The ENCELIUM Energy Management System is comprised of the ENCELIUM GreenBus™ communication network and the ENCELIUM Polaris 3D software. ENCELIUM GreenBus is a networked system designed specifically for controlling lighting to achieve maximum energy savings and optimum lighting comfort. It enables cost-effective, individual dimming control of all fixtures in a building by integrating peripheral devices, including luminaires, switches, and sensors, with front-end servers via dedicated ENCELIUM GreenBus cabling, into a complete programmable lighting solution.

ENCELIUM Polaris 3D is the central control software application used to configure, commission, and manage the ENCELIUM EMS system. It enables configuration of every lighting system parameter in a building for each individual user or space and establishes the baseline settings for the following system features: Daylight Harvesting, Occupancy Control, Smart Time Scheduling, Task Tuning, Personal Control and Load Shedding.

With the ENCELIUM Polaris 3D software, facility managers can monitor any lighting irregularities and make adjustments directly from their own desktops or laptops. The Strategies. The ENCEIUM Energy Management System seamlessly integrates six energy management strategies: Smart time scheduling, daylight harvesting, task tuning, occupancy control, personal control, and load shedding.

Wireless Option

The new ENCELIUM Wireless Energy Management System (EMS) is a robust portfolio of sleek hardware solutions designed to expand lighting control to hard-to-reach locations and simplify and lower the overall cost of installation. Developed in North America and accessible anytime, anywhere via an Internet connection with Polaris 3D light management software, the ENCELIUM Wireless EMS is based on the ZigBee Pro network stack and includes wireless managers, sensors, control modules for attaching to light fixtures, and wallstations.

“Architects and building owners have long been turning to ENCELIUM, with over 50 million square feet of space currently managed by our Energy Management System,” said Chuck Piccirillo, marketing director for ENCELIUM systems, OSRAM SYLVANIA. “Now with new wireless capabilities, ENCELIUM systems truly stand out in the market, delivering flexible and cost-effective solutions that bring existing lighting devices and spaces into a digital world.”

Awarded Top Product Designation

One of 20 expo products as seen at the annual AIA 2015 conference, which drew thousands of architects and design professionals to Atlanta in May, the ENCELIUM® Energy Management System and its wireless counterpart have been ranked as a “Top Product Pick for Specifiers” by an independent committee of writers and publicists who cover architectural and building envelope product news year-round.

All exhibitors of the AIA 2015 expo were invited to participate in the top products consideration and selection process. Leading up to the event, product manufacturers with displays planned for the expo were invited via email to submit completed product forms with photos to be considered by the panel, which was led by Eberly & Collard Public Relations. The firm specializes in public and media relations in the architecture, construction and design industries, which involves the firm’s staff contributing and writing design case-studies and product profiles for numerous trade and mainstream media outlets each year.

The autonomous panelists who reviewed more than 350 products and selected the top 20 product picks conducted the research in neutral jury format, whereas existing clients of the firm were exempt. Those products included in the top 20, which are being revealed individually during fall and winter 2015, were chosen based upon three factors, including advanced technology, innovative design and aesthetic visual appearance.
