National Renewable Energy Laboratory Study
Executive Summary
The technology demonstrated was Transformative Wave’s eIQ building management system (BMS), which automatically responds to DR signals. The BMS controlled the HVAC rooftop units (RTUs) using the CATALYST retrofit solution from Transformative Wave. The nonHVAC loads were controlled using hardwired and ZigBee wireless communication. The wireless controllers, manufactured by Autani, were used when the electrical layout was too disorganized to leverage the less-expensive hardwired control.
