2013 Title 24, Part 6 Outdoor Lighting Guide

2013 Title 24, Part 6 Outdoor Lighting Guide
02/24/2015

The California Lighting Technology Center’s 2013 Outdoor Lighting Guide for Title 24, Part 6 compliance is designed to help builders, lighting industry professionals, and others navigate the nonresidential outdoor lighting portion of California’s Building Energy Efficiency Standards. The new standards, which took effect July 1, 2014, include updated requirements for retrofit standards, lighting controls, and uplight and glare limits.

CLTC Helped To Successfully Commercialize Next-Generation Sensor

Published: Thu, 12/11/2014

The commercialization of Echelon's Lumewave MWX-LVE long-range outdoor microwave sensor illustrates CLTC's success in supporting advanced sensors for adaptive outdoor applications.

CLTC demonstrated and supported the next-generation sensor, which detects movement and can distinguish between slow and fast moving objects such as pedestrians, cyclists and motorized vehicles. The sensor reacts to the size of objects from longer distances, automatically raising the light levels to high output when the areas are occupied and lowering them when areas are vacant.

DLC Stakeholders Meeting - Keynote Presentation

07/31/2014

2014 DesignLights Consortium Stakeholder Meeting, San Diego
Presented by Michael Siminovitch​

On July 29, 2014, CLTC Director Michael Siminovitch gave a keynote address to those gathered for the annual DesignLights Consortium Stakeholder Meeting. The attached presentation begins with examples of wasteful lighting practices then explores control strategies and emerging technologies that have demonstrated deep energy savings. Case study results and information on UC Davis's Smart Lighting Initiative are included.

Adaptive Outdoor Lighting for the Health Care Sector

07/14/2014

In 2014, NorthBay VacaValley Hospital became one of the first U.S. health care facilities to install a network-controlled adaptive outdoor LED lighting system. The hospital already had up-to-date, energy-efficient outdoor lighting installed, yet this award-winning installation reduced the hospital's outdoor lighting energy use 66.4%. Energy savings correspond to occupancy rates of 35–55% observed at different areas of the site.

 

Networked Adaptive Parking Lot Lighting

07/02/2014

In 2012, UC San Francisco launched a pilot demonstration of energy-efficient lighting on the top level of its two-tier parking garage on Post Street in San Francisco. That level of the parking structure had lacked lighting for some time, but a sharp increase in use prompted calls from nearby residents expressing safety concerns. CLTC and collaborators succeeded in delivering ultra-efficient lighting where and when it was needed while minimizing light trespass so as not to disturb residents of the apartment building next door.

SPEED Business Case: Adaptive Street and Area Lighting

06/13/2014

This business case explores various lighting control options for LED retrofits of street and area lighting, along with funding and financing sources. It provides a general economic analysis of the costs and benefits associated with street/area retrofits and new-construction installations of post-top luminaires. The scenarios presented in this business case analysis have the potential to reduce lighting energy use and carbon emissions 72–93%, in areas with an average occupancy rate of 20%.
 

Adaptive Exterior Lighting, UC Santa Barbara

05/28/2014

In 2013, UC Santa Barbara partnered with the SPEED team to demonstrate network controlled LED lighting for streetlights and post-top fixtures. These exterior fixtures were purchased with dimming power supplies and equipped with radio frequency (RF) control modules. The post-top fixtures were also equipped with occupancy sensors. These lighting controls allowed all the units to be incorporated into an adaptive mesh network control system that optimized the fixtures’ energy efficiency and gave the campus unprecedented control of its lighting. 

Networked Adaptive Exterior Lighting for the Health Care Sector

NorthBay VacaValley Hospital networked adaptive exterior lighting post-retrofit
05/28/2014

In 2014, NorthBay VacaValley Hospital became one of the first U.S. health care facilities to install an energy-efficient, ultra-smart outdoor LED lighting system. The award-winning project was so successful that the NorthBay Healthcare group is now considering expanding the VacaValley system and retrofitting the outdoor lighting at other sites. 

Bi-level Induction Area Luminaires

03/21/2011

The combination of occupancy controls, a bi-level generator, and an induction source produces an energy-efficient luminaire with exceptionally long life, good color quality, and dynamic light level response based on actual usage. The bi-level controls contribute additional savings that are directly proportional to automotive and pedestrian traffic patterns. Bi-level luminaires reduce to 50% power on vacancy and increase to 100% power on occupancy.
