680 Craig RdA Jarrell Case Study

Project Overview

Jarrell completed the control upgrade project at 680 Craig Road for Larson Capital Group. This building had existing pneumatic HVAC controls that were upgraded to Trane DDC. The team also implemented occupied/unoccupied space temperature setback along with CO2 based demand-controlled ventilation, optimum start and supply air reset.

The estimated savings for this project is over 500,000 kWh which is over a third of their annual energy consumption. This energy savings resulted in an incentive of $60,153.12. The incentive check is 10% larger than that because Ameren’s program was doing and “end of the year push” bonus of 10% if projects were completed by a certain date.
