Minimizing Energy Costs Through Data and Partnership


Declining student enrollment and lower revenues left Homestead High School with the challenge of determining ways to reduce costs while maintaining an environment conducive to learning, and supportive of significant after-hours use of the facility by the community. With fewer dollars available to pay rising gas and electric bills, as well as significant demand charges, the school sought ways to save.

Introducing a knowledge-based solution
Homestead High School had previously initiated a building re-commissioning. While the energy-focused tune-up was somewhat helpful, Homestead knew they needed an ongoing solution to help increase efficiency and achieve cost-saving objectives. The school met with Trane to discuss their needs. Trane assessed the situation and proposed the knowledge-based Energy Performance solution to evaluate and improve building operations and efficiency.

Gathering data to enable informed decisions
Trane’s Energy Performance solution facilitated monitoring, analysis, and reporting to help Homestead make informed decisions to optimize building operations. From 494 collection points, the tool gathers data every fifteen minutes, collecting more than 47,000 points of data daily from meters, sub-meters, sensors and the building automation system. Homestead facility managers use a customized dashboard to display key information, with multiple formats allowing standard views of different variables.

The Trane Energy Performance solution provides real-time tracking of energy use for comparison to projections to improve budgeting and forecasting. The tool also allows the facility manager to calculate the cost of energy consumed during the school day and for after-hours community events, arming the district with the knowledge needed to make informed decisions regarding facility use.

Using data analysis to manage energy use
Using a quick visual representation of the building’s energy consumption, Homestead gained insight into their usage peaks and valleys to identify hidden energy waste and opportunities for potential energy conservation measures. Trending tools allowed Homestead to drill into the building’s energy usage to identify operational abnormalities and areas of highest consumption and cost. Viewing past HVAC, lighting, and other system data enables facility managers to predict future patterns and make adjustments to better manage building operations and energy use.

Partnering to perfect energy management strategies
Acting as a “second set of eyes” Trane worked with Homestead High School to improve the school’s business climate. Key Performance Indicators (KPIs) identified upfront were monitored to collect performance data and analyzed to evaluate efficiency. Reports generated by Trane for Homestead allow facility managers to view actual results vs goals and see areas for potential improvement.

Trane professionals provided Homestead facility managers and staff with training, coaching and guidance on energy management strategies. Using screenshots from the Energy Performance tool, Trane demonstrated areas for concern and helped Homestead analyze data to make knowledgeable facility management decisions.


Data collected from Trane’s Energy Performance solution showed that Homestead High School was running more efficiently, with electrical energy consumption approximately 10 percent below similar buildings, as benchmarked by the Department of Energy Buildings Performance Database.

Homestead predicts future energy savings to be more than $40,000 a year. Drawing on coaching and knowledge from the Trane Energy Management tools and personnel, Homestead maintains an optimal learning environment, has engaged students and staff in its energy-saving program, and created awareness among district administrators regarding energy usage. The ability to see the results of strategic actions fifteen minutes after implementation provides Homestead with a great feedback mechanism for continual evaluation of energy use and ongoing development of energy management strategies.

“We’ve discovered that energy management isn’t finding that one silver bullet," said Kyle Thompson, director of buildings and grounds, Mequon-Thiensville School District. "It’s doing a bunch of little things that make the savings.”

“Energy-efficient equipment is important, and we’re lucky to have the building automation, but that only gives you so much,” Thompson added. “It’s not about equipment and controls, it’s about having the information and knowledge we need to run our building smartly.”
