Southwestern College (SWC), located in Winfield, Kansas, is a private Methodist institution established in 1885. Occupying 82 acres, it emphasizes service learning, boasting programs in leadership, discipleship, and sustainability. Affectionately known as “The Mound,” the college offers bachelor’s degrees and opportunities for undergraduate students to pursue graduate studies across various master’s programs.

ESP started working with Southwestern College in Fall 2020, amid the COVID pandemic. Seeking to enhance its facilities, the college aimed to improve indoor environments for students and staff, fostering a better learning and working atmosphere. Working together, SWC and ESP conducted an Investment Grade Audit (IGA) of the campus, evaluating utility costs and energy consumption trends.

Following the campus IGA, SWC implemented an energy performance contract (EPC) structured into five phases, commencing with lighting. In 2021, ESP supervised extensive LED lighting enhancements in 24 campus buildings, alongside improvements in exterior lighting and the installation of occupancy sensors. The remaining phases encompassed two for hot water heating, retro-commissioning, and the integration of smart thermostats.

Installing newer equipment had fewer maintenance issues, enabling staff to concentrate on upkeep and preventive maintenance, ultimately extending the lifespan of the equipment. Standardized equipment reduced the need for stocking large quantities of parts, simplifying replacements and repairs. The project, partially funded by redirecting utility bill expenses, stimulated the local economy by creating jobs, purchases, and projects. The energy-saving measures led to annual electricity savings of 1,394,220 kWh.
