CA Energy Efficiency Strategic Plan: Lighting Chapter

03/01/2011

Lighting accounts for approximately 25 percent of California’s energy use, making energy-efficient lighting technologies a vital part of the state’s strategy for meeting its legislated climate goals. The Lighting Action Plan details the lighting portion of the California Energy Efficiency Strategic Plan, a comprehensive roadmap outlining solutions for reducing California’s energy consumption.

NEAA Study: Technology & Market Assessment of Networked Outdoor Lighting Controls

06/01/2011

This study focuses on controls systems designed for street and parking lot lighting applications. These systems provide tools to manage and monitor city-wide streetlight assets remotely, including the potential to meter actual street lighting energy use. Networked controls that offer dimming capability can also provide energy savings through adaptive street lighting management, the practice of reducing lighting power and output as conditions change over time.

Max Tech and Beyond: Maximizing Appliance and Equipment Efficiency by Design

07/01/2011

This project examined energy end-uses in the residential, commercial, and in some cases the industrial sectors. The analysis attempts to consolidate, in one document, the energy savings potential and design characteristics of best-on-market products, best-engineered products, and emerging technologies in research & development. 

SCE Smart Corridors: Bi-level Lighting for Office Applications

10/01/2011

The objective of the Smart Corridor project is to quantify the potential energy savings in corridor lighting by implementing bi-level lighting technologies in commercial spaces such as office, hospitality, and educational buildings while also evaluating the market potential for the bi-level lighting strategy. The energy savings data gathered from this project is crucial to the large-scale implementation of bi-level strategies, as it will support the inclusion of bi-level lighting practices for secondary spaces in utility incentive programs and, eventually, building code language.

CLTC: Smart Corridor Lighting

04/01/2011

This demonstration project consists of a one-to-one retrofit of existing fluorescent luminaires with either new fixtures or new components for three corridor areas in Bainer Hall. This project is intended to demonstrate the energy savings that can be achieved by using occupancy-based controls for interior corridor applications. 

CLASP Analysis of Background Illuminance Levels During Television Viewing

12/01/2011

Televisions account for a growing portion of residential energy use worldwide. In the U.S. alone, TVs consume approximately 50 billion kWh of energy each year. Energy efficiency standards and labeling (S&L) programs, including the EPA’s ENERGY STAR program, have saved significant energy; now the Department of Energy is developing a federal test procedure to measure the energy efficiency of various television sets.

In support of these efforts, CLTC partnered with the Collaborative Labeling & Appliance Standards Program (CLASP) to conduct a field study of typical background lighting levels during in-home TV viewing. Data collected through the study—based on a diverse sample of 60 homes, 30 in Sacramento and 30 in the Washington, D.C. area—will enable ENERGY STAR, the DOE, and other regulatory entities to measure the energy consumption of TVs when the automatic brightness control (ABC) feature is engaged in a way that more accurately reflects actual use.

Hotel Guest Room Energy Controls

12/01/2008

CLTC and WCEC, in partnership with San Diego Gas & Electric, conducted a study at four hotels in the San Diego area utilizing three brands of occupancy controlled guest room thermostat products. The main objective of this assessment was to compare the energy use of the emerging technology with the existing technology. The adoption of advanced control systems in the hotel industry has been slow due to high labor cost of installing systems, maintaining the post installation integrity of the system, and lack of verified energy savings.

Consumer Preference Survey on Directional LED Replacement Lamps for Retail Applications

12/01/2012

Pacific Gas and Electric Company (PG&E) partnered with the California Lighting Technology Center (CLTC) at the University of California, Davis, to assess how education or incentive programs for lighting that uses light-emitting diode (LED) technology might best serve retail business owners within PG&E’s service territory. LED replacement lamps provide a solution for business and building owners looking to increase the energy efficiency of their lighting systems in order to meet, or exceed, 2013 Title 24 standards.
