An off-campus facility that houses 650 students in a $67 million mixed-use village on a 34-acre parcel of land is an innovative public-private partnership between a Mississippi D-1 university and the largest apartment property manager in the U.S.
These partners, as a part of their clean energy infrastructure project, had a Combined Cooling, Heat, and Power (CCHP) system designed and installed. The goal was to operate a centralized heating and cooling plant that runs efficiently and economically, to provide HVAC and electricity to the entire complex with maximum resiliency in the event of grid failure. The energy consultants working with the partnership contacted CoolSys when the unit was inoperable at start up.
An in-depth inspection by CoolSys of the CCHP equipment identified areas requiring additional integrations and upgrades prior to start-up and then commissioning of the inoperable cogeneration unit. Though the partnership had numerous goals, they did not have adequate internal resources to properly maintain the new equipment and achieve their efficiency and sustainability goals.
DIAGNOSTICS & ISSUE RESOLUTION
CoolSys CoGen specialists conducted a thorough technical assessment of the systems, pinpointing the root causes of the underperformance. From network glitches to incorrect calibrations, all issues were addressed and resolved.
OPTIMAL COMMISSIONING & SYSTEM UPGRADES
CoolSys customized the system and commissioned the CCHP unit to enhance overall operability. CoolSys calibrated the infrastructure to operate in optimum balance with other critical systems, such as the absorption chiller, external radiators, and existing boilers, ensuring seamless operations and maximum energy efficiency.
PREVENTIVE MAINTENANCE IMPLEMENTATION
CoolSys introduced a comprehensive preventive maintenance program covering all system components. This included regular inspections, calibration, and predictive replacements to prevent future failures.
24/7/365 MONITORING & REAL-TIME RESPONSE
A central pillar of the solution was the implementation of constant system monitoring to detect and resolve issues as they occurred. The efficacy of this approach became evident when, shortly before midnight on New Year’s Eve, a power failure disrupted four out of the six units.
Within minutes, the monitoring team identified the issue, connected with the local technicians, and assisted the on-call shift operator in resetting the network protection. All compromised systems were restored to full functionality in under 30 minutes—a testament to the resilience of CoolSys’ solution.
CoolSys CoGen’s expert team stepped in to address the center’s challenges, employing a multifaceted approach to assess, repair, retrofit, commission, monitor the systems 24/7/365, and maintain to prevent further outages and inefficiencies.
The CCHP system now operates at an impressive 98%+ availability year after year, while delivering more than 42,000 operational hours of resilient, efficient power to the property consistently and reliably.
The facility reduced costs by $200,000 annually, totaling $1.2M over the 6 years the systems have been under CES care. For this reason, the client has decided to extend the agreement for an additional 5 years.
By optimizing the system’s energy use, the off-campus student housing complex significantly reduced its greenhouse gas (GHG) emissions by 39%, reinforcing its commitment to environmental sustainability.
By properly calibrating and maintaining the systems, the CHP units exceeded the projections with 98 %+ resiliency. The monitoring and service played a vital role during an emergency on-site situation, ensuring students had domestic hot water, HVAC heat, and operating elevators without interruption at a crucial time.

The results of CoolSys CoGen’s commissioning, monitoring and service were transformational for the client organization. Addressing both the immediate and long-term inefficiencies, the facility experienced measurable improvements across key performance indicators. The success of this project strengthened the client’s trust in CoolSys. Recognizing the value and reliability delivered, the property managers have extended CoolSys’ maintenance and monitoring services for five additional years. This expansion further underlined CoolSys’ position as a trusted partner in ensuring operational excellence.
