The Hurst-Euless-Bedford Independent School District (HEB ISD) makes a deliberate attempt to reduce expenses that are not aimed at improving student achievement. In support of this purpose, HEB ISD strictly manages its utility expenses.
The school district takes a holistic approach to overall energy consumption and has decided to incorporate the latest technologies to be more energy efficient. As a result of these efforts, HEB ISD has become one of the most energy-efficient school districts in the state of Texas.
The school district’s energy consumption reduction program continues to stay a step ahead of the state’s energy code. With the future in mind, HEB ISD wanted a centralized lighting control system that could support each classroom’s requirements and could easily scale with more classrooms and buildings implemented over time.
A lighting architect recommended Osram’s ENCELIUM® Networked Light Management System. Then, after extensive testing in a portable classroom, the district chose to go with the ENCELIUM system. Now, three newly constructed facilities the Viridian Elementary School in Arlington, Texas, the Gene A. Buinger Career and Technical Academy in Bedford, Texas, and the Auxiliary Services Center in Euless, Texas take advantage of the capabilities of this smart lighting solution.
ENCELIUM System Allows Customization for Individual Classrooms
With the understanding that lighting directly affects learning, the district customized every Viridian Elementary classroom’s lighting to meet the needs of particular tasks and classroom areas with the help of the ENCELIUM System’s task tuning capability. For example, in the pre-kindergarten classroom, the lighting settings are programmed to include nap time. During this time, all lights are shut off except those over the teacher’s desk. Another classroom, this one for special education, utilizes mild lighting to ensure that the lighting doesn’t overstimulate the students.
After a supervisor experienced migraines once bright LEDs were installed in his office, he was able to dim the lights to better satisfy his personal preferences with a mouse click with the ENCELIUM System. Afterwards, his migraines ceased.
Occupancy sensors used in all three buildings make sure that lighting is turned off when a room is unoccupied, and then it turns on automatically when someone enters. This capability vastly reduces energy consumption in buildings that are often empty in the evening, weekends and during vacation periods.
When classes are in session, corridor lights are set to a low 30% to save energy, and they automatically intensify when someone enters the corridor.
“The move to the ENCELIUM System was a big step for our district and we had a lot riding on that decision. It’s really paying off in student comfort, educational experience, and energy savings. It does everything I need it to do and then some,” commented Larry Parker, energy manager of HEB ISD.
Osram asserts that the ENCELIUM System’s user-friendly energy consumption dashboards let HEB ISD easily adjust lighting where needed. The district shares the system data on energy consumption with other energy-focused organizations including the Texas Energy Managers Association (TEMA) where Parker serves as Chapter Vice President. The data is compiled into an Energy Report Card for all of the district’s academic buildings. The installation of a smart LED lighting system from Osram is just the district’s latest project to reduce energy consumption.
“I joke that I am a flexible control freak. The ENCELIUM System allows me the flexibility of functional control so that I can provide our customers the best environmental conditions for the least expense,” said Josh Minor, director of maintenance and operations of HEB ISD.
HEB ISD Saves 56 to 65 Percent Compared to Previous Lighting
The average energy cost for lighting in HEB ISD academic buildings that have not installed the ENCELIUM Networked Light Management System runs about 50 to 70 cents per square foot. However, the buildings in which the ENCELIUM System has been installed consume dramatically less electricity for lighting at merely 23 cents per square foot with an overall energy cost savings of 56-65% compared to the previous lighting.
In addition to the electricity savings that the district expects from the smart LED lighting system in several of schools in the district, HEB ISD received a $26,000 rebate from its utility company for the system installation at Viridian Elementary School alone. The district has commenced plans to retrofit three additional district elementary schools with the ENCELIUM System.
Eventually, HEB ISD wants to integrate the ENCELIUM System with other Building Management Systems (BMS) such as HVAC.
This integration is expected to result in a further reduction of electricity consumption.
