Shelbyville, SHELBYVILLE, IN
Shelbyville Central Schools was seeking efficiency upgrades to the HVAC system in Shelbyville Central Middle School.
ECS Midwest delivered energy efficiency upgrades that resulted in annual energy savings of $245,311.00 each year for 10 years, for a total of $3,463,365.00. These savings paid for the entire project with an additional $1M in savings.
ECS Midwest installed two high-efficiency boilers with digital controls and two hot water circulating pumps with variable frequency drives. All equipment had temperature sensors to monitor and control start/stop operations and sequence operations.
The chiller and pump were replaced with two roof top air-cooled chillers with digital controls and temperature sensors. Two chilled water circulating pumps with variable frequency drives for each pump were also installed. Digital controls and pressure sensors were included to monitor and control the sequence of operations. ECS Midwest installed two new chilled water cooling air handling units in the main classroom. These units will utilize fresh air for “free” cooling. This included digital controls and temperature sensors.
ECS Midwest provided a new network of Direct Digital Controls for 10 air handlers, 12 exhaust fans, and three unit ventilators. This included 118 direct digital controllers, room sensors, and electric hot water reheat valves.
In the school’s gymnasium, a new packaged chiller water cooling and hot water heating air handling unit were installed. This unit also utilizes a fresh air economizer for “free” cooling. An air supply return was installed to connect the new air handling unit with the existing supply and return air ductwork.
Shelbyville Central Schools consists of Shelbyville Senior High School, Shelbyville Middle School, Coulston Elementary, Loper Elementary, and Hendricks Elementary with total district enrollment at approximately 4,000 students.
All of the five schools in the Shelbyville Central Schools Corporation received “A” accountability grades from the Indiana Department of Education for the 2014-15 school year. The school corporation also received an overall “A” score on the Indiana’s A-F Accountability Report card for the fifth consecutive year!
