The typical existing inventory of high mast fixtures is made up of either high pressure sodium fixtures or legacy MH fixtures. This project will evaluate the energy efficiency and demand reduction potential of retrofitting the high masts with the new generation LED fixtures. To accomplish this the...

Project SummaryThe goals of the project were: 1) to demonstrate the impact of precise light distribution of LEDs on energy efficiency and lighting quality 2) improve the lighting for broadcasting; 3) complete ballpark lighting control system to improve energy efficiency through control and allow...

The solution selected for study in this report is a connected LED lighting system with embedded sensors and wireless controls integrated into the luminaire. The luminaires can connect wirelessly to wireless access controls (WACs) that are connected to the EMS. This smart luminaire with...

Project SummaryThis report explores the potential role utilities may play in the emerging home energy management (HEM) marketplace and develops a roadmap to leverage, promote, and enable the use of these technologies for energy savings and grid load reduction. It takes a comprehensive view of...

Phase One of San Diego Gas and Electric’s Digital Billboard Project “Digital Billboard Use in California: ET14SDG8011” consisted of a description of digital billboards’ technology, preliminary energy profile, and a California market characterization. The final report,...

Advanced lighting control systems provide networked control and monitoring capabilities of connected luminaires via onboard metering and system reporting features. These advanced features allow system owners to dynamically balance visual comfort and lighting energy use. CLTC, in collaboration with...

Project SummaryDemonstrate and Assess High Performance Envelope strategies for commercial buildings and how they interact with Lighting, Daylighting and Office Equipment Loads to better T24 2013 Code compliance by...

This project will verify the demand and energy savings potential of electrodeless HID over a traditional HID (existing system) at a warehouse (customer site). Light levels will be compared to the existing system. Payback and life cycle cost will also be evaluated for this technology. Technology...

This project will evaluate dedicated LED track lighting systems, which do not allow for conversion to other source types. Additionally, the use of LED screw-base lamps for use with traditional track lighting, current limiting devices and phase-cut dimming controls will be evaluated at both line and...

This project is aimed at understanding the actual EUL values of LED based products by performing a combination of field measurements, lab evaluation, and data compilation. This effort consists of (1) field measurements of deployed LED based lighting to determine their current performance and rate...
