Case Study: a long-established public university achieves 33% cooling efficiency gains with Accruent EMS and Events2HVAC

a long-established public university boosts cooling efficiency 33% with Accruent EMS

A long-established public university faced a significant challenge with energy waste in its student union building. The union's HVAC system was running on a fixed schedule from 6:00 am to 12:00 pm, regardless of whether its many rooms were occupied, leading to unnecessary costs. To address this, they turned to their existing vendor, Accruent EMS, and sought to integrate it with their building automation system to control heating and cooling based on actual room schedules.

The solution implemented by Accruent involved integrating their EMS software with Events2HVAC to automate HVAC commands for 26 key rooms. This integration ensured that heating and cooling only occurred when rooms were scheduled for use. The results were dramatic: over an eight-month period, the university achieved a 33% increase in cooling efficiency and a 17% increase in heating efficiency, leading to calculated electricity savings of $10,000. Accruent's solution enabled significant cost avoidance and a major reduction in energy use.
