Texas Tech’s eSight Energy Management Program Expands as Energy Costs Shrink


Texas Tech University is a Tier I University located in Lubbock, Texas with over 38,000 students. Since 2000, Texas Tech has lowered its energy budget by $6 million and reduced its energy use index by 37%; even as the campus has grown by two million square feet and student population has increased by 51%.

Persistent Commissioning

Texas Tech implemented the eSight® energy management software (EMS) as a means of effecting a transition from reactive maintenance to persistent commissioning. Reactive maintenance is the practice of correcting equipment failures after they make themselves known. Persistent Commissioning is identifying failures as or even before they occur and taking immediate action to restore as-new performance.

Texas Tech searched for a customizable EMS that harvests real-time energy data to quickly identify energy savings opportunities and improve the response time of repairs. They needed a modular, scalable solution that was rich in analytic capabilities and low in initial cost of implementation.

The Solution

Texas Tech selected eSight for many reasons: eSight provides an abundance of user-friendly analytical tools, particularly CUSUM analysis, and modular features that are not offered by any other software. The modularity and scalability of eSight allowed Texas Tech to design a low-cost pilot project and implement the innovation by integrating existing meters before investing in new meters.

During the pilot, eSight Energy worked with several control companies and Texas Tech’s Energy Management Team to integrate data from a select few meters into the eSight platform. In addition to the industry-leading analytics of eSight, the ease of deployment and low initial costs provided a quick return on investment.

The Results

On the day the eSight Energy EMS was powered up in July 2015, it identified a $220,000 savings opportunity in the English/Philosophy building, on which Texas Tech quickly capitalized. In the second year, similar corrections produced savings of over $500,000.

Since that astounding return on such a low-cost implementation, Texas Tech has integrated meters from 49 buildings with plans to expand to 200 buildings over the next several years.
