Revitalizing Building Performance: Optimization of Underutilized Systems

EASI transformed Prince Georges County Public Schools’ underperforming building automation systems through comprehensive retro-commissioning, reducing energy consumption by 20% and dramatically improving occupant comfort.

The Challenge

Prince Georges County Public Schools had invested in modern HVAC equipment and automation systems, but these assets were severely underutilized since their initial installation. The buildings suffered from misaligned schedules, inconsistent temperatures, and significant energy waste. Without proper system performance insights, the facilities team struggled to identify and address the root causes of these ongoing issues.

Analysis and Solution

Through a detailed system audit, EASI discovered that despite having capable technology in place, the BAS was not properly configured to match actual building usage patterns. Based on these findings, we implemented a comprehensive retro-commissioning plan that included adjusting HVAC schedules to align with occupancy patterns, calibrating sensors and controllers for accurate readings, and optimizing temperature setpoints and ventilation rates. We enhanced the BAS with advanced reporting tools and dashboards while providing in-depth training to ensure the facilities team could maintain these improvements long-term.

The Results

The retro-commissioning project delivered a 20% reduction in energy consumption, generating annual savings of $50,000 and reducing the district’s carbon footprint by 15%. Temperature-related complaints decreased by 90% as comfort conditions improved throughout the buildings. According to Jason Walker, the project was “transformative,” providing not only immediate improvements but also the tools and knowledge needed to maintain optimal system performance going forward.
