The Issue

California Senate Bill 350 aims to double statewide electricity end use savings from energy efficiency and conservation measures by 2030. Meeting this aggressive target will require the commercial building industry to install holistic energy efficiency technology packages that are emerging, pre-commercial products. According to the 2013 Navigant California Potential and Goals Study, aging, existing commercial buildings, particularly in inland communities, present the greatest energy savings potential. Emerging technologies such as retrofit RTU motors, DC lighting, direct-evaporative cooling, and a cloud-based control platform will demonstrate 20% onsite energy reduction.

Project Innovation

This project demonstrates the impact of an integrated suite of pre-commercial energy efficiency technologies in a large, existing, retail building located near a disadvantaged community. One of the technologies that comprise the installation package includes a novel supervisory controller to provide system-wide optimization, to reduce electricity consumption across numerous building subsystems, including lighting, refrigeration, and heating, ventilation, and air-conditioning. This could enable site electricity savings of greater than 20%.

Project Benefits

This project demonstrates how pre-commercial energy efficient technologies can deliver cost-effective, deep electric savings in a big-box retail environment, while also showcasing the demand reduction potential of these strategies. The project team will install a holistic suite of pre-commercial technologies such as a variable speed rooftop unit (RTU) high rotor pole switched reluctance (HRPSR) retrofit motor, direct current (DC) LED technology, direct-evaporative cooling to treat RTU condenser inlet air, and a cloud-based control system that will monitor all systems and detect energy waste, equipment malfunctions, and other operational problems. These technologies have the ability to demonstrate 20% energy savings.

Lower Costs: The project could result in lowering on-site electricity use by 20 percent.

Greater Reliability: The project adds valuable capacity to California's electrical transmission and distribution system by reducing power consumption of packaged HVAC systems which are disproportionately responsible for critical capacity shortfalls on the grid. The demand response controls will maximize the use of variable renewable resources, such as the site's PV system.
