Challenges Faced by Texas Schools
High Energy Costs and Carbon Emissions
Texas schools have long struggled with outdated lighting systems, relying on fluorescent and incandescent bulbs that guzzled energy. Lighting alone made up about 40% of a school’s total energy use, with U.S. schools spending an average of $130 per student annually on electricity [8]. Compounding the issue, these legacy systems lacked modern features like occupancy sensors or timers, leaving lights on in empty spaces. On top of that, traditional bulbs generated excess heat, pushing HVAC systems to work harder. Many Texas schools, especially those built in the 1950s, still operated with their original fixtures, which were far from meeting today’s energy standards [7].
A stark example of this comes from Round Rock Independent School District, which faced these challenges across its 51 facilities in November 2025. Their outdated fluorescent lighting consumed a staggering 13,313,729 kWh annually, costing the district approximately $1,308,557 [6]. Reflecting on the situation, Colton Churchill, Executive Vice President of Sales at Excel Energy Group, highlighted the dual benefits of addressing these inefficiencies:
"Districts are under pressure to deliver more value with the same dollars. Lighting is one of the few measures where you can improve instructional environments and generate budget relief at the same time." [6]
Beyond escalating costs, these outdated systems demanded constant upkeep, further straining school resources.
Frequent Maintenance and Schedule Disruptions
The operational demands of traditional lighting systems extended well beyond their energy inefficiency. For example, a large Austin-area school district reported spending 40 hours of maintenance labor every week just to replace light bulbs before upgrading in September 2022 [1]. The poor quality of lighting often made matters worse, forcing districts to bring in outside contractors for after-hours work, which added to already tight budgets [11].
Jose Macedo, Director of Maintenance at Angleton Independent School District, spoke to the need for noticeable improvements when investing public funds:
"We’re spending public funds, so we not only need an ROI, but want our staff and students to SEE something for our money." [7]
In addition to the high maintenance demands, the lack of flexibility in lighting controls further hindered efficiency.
Limited Lighting Control and User Customization
Traditional lighting systems offered little to no flexibility. They were either fully on or off, leaving teachers unable to adjust individual fixtures or modify light temperatures to suit specific classroom activities. This often resulted in entire zones being fully lit, regardless of whether they were in use or if natural light was available [1]. Moreover, these systems lacked the ability to integrate with other building systems like HVAC, fire alarms, or security, which not only wasted energy but also complicated maintenance efforts.
To tackle these limitations, Angleton Independent School District implemented a $90 million bond program to upgrade 12 campuses. By installing Keystone LED products, the district cut power consumption by over 60% and significantly reduced maintenance needs. They also used specialized "Future Fit" kits to avoid disturbing asbestos-containing ceiling tiles, a common issue in older buildings [7]. These upgrades highlighted the importance of adopting smart, integrated lighting solutions that offer automation, customization, and improved efficiency.
