20+% energy reduction in one year
Challenge
Complex building with various uses
- As one of the main congregation areas on campus, Tangeman University Center is a mixed-use building for public assembly, retail and food service
- Originally built in 1937, upgrades, additions and renovations over the years had led to a complex system with a multitude of mechanical system types that all needed to work together
- Needed to control building pressure throughout the facility
- Needed to optimize the energy consumption of the facility’s equipment
Approach
Reprogrammed for efficiency
- Pathian® provided project management, engineering, and commissioning services
- Reprogrammed seven large AHUs to operate under Pathian’s patented control methods
- Provided a new PXC/M DDC Controller/Ethernet – IP for each of the seven AHUs
- Provided a BACnet – IP/Driver for the Client/Server for communication
- Provided new pressure sensors, pressure switches, pneumatic control signal/transducers, minimum outside airflow stations, new building pressure sensors, and humidity sensors
- Implemented Pathian Analytics software to track, evaluate and sustain optimal equipment performance
Results
Saving energy and cost
- Reduced energy usage by 20.6% from project start to post commissioning without COVID influences
- Total project cost: $359,800
- Project actual savings: $93,131 in electric, chilled water, steam
- Simple Payback: 3.86 years
