Sinisa Novakovic, owner of Mishka’s café in downtown Davis, had two goals for the recent lighting upgrade in his café: create a cozy, inviting atmosphere for customers and save energy. In the main seating area alone he was able to cut his lighting energy use 85% by upgrading to LED lighting. Throughout the rest of the café, energy consumption for lighting has been cut in half, reducing Mishka’s annual energy use by over 10,000 kWh and saving Novakovic nearly $2,000 every year in energy costs. The lighting upgrade will have paid for itself after just eight months.

The purpose of this handbook is to furnish guidance for planning and conducting a highperformance building charrette, sometimes called a "greening charrette." The handbook answers typical questions such as, "What is a charrette?", "Why conduct a charrette?", "What topics should we cover?", "Whom should we invite?" and "What happens after the charrette?". Owners, design team leaders, site planners, state energy office staff, and others who believe a charrette will benefit their projects will find the handbook helpful.
Adaptive exterior lighting is a relatively new concept recognized by the lighting industry and energy regulators as a potential method to increase energy savings in outdoor applications. Many adaptive exterior lighting products are being developed and have been introduced into the marketplace, allowing users to implement dynamic lighting designs that offer 30%–75% energy savings over traditional systems. These savings are achieved by coupling advanced lighting controls with an efficacious, dimmable source.
In the summer of 2010 the California Lighting Technology Center (CLTC) and Philips Hadco produced a bi-level solution that combined a dimmable LED source and a mounting collar equipped with occupancy sensors. The collar provides 360-degree occupancy sensor coverage. This demonstration involved whole-head replacement of the existing luminaires, but results could also be achieved with a retrofit kit. The new luminaires feature good color quality, improved efficiency and a longer lifespan. Adaptive controls enable the bi-level luminaires to reduce power to 50% during vacant periods and increase to 100% light output when occupants approach. Switching between the two light levels maintains adequate light for security and wayfinding while maximizing energy savings.
In 2012, University of California Davis upgraded its exterior lighting as part of the university’s Smart Lighting Initiative. Wall packs on campus, like other exterior lighting fixtures, were retrofitted with dimmable LED sources, motion sensors, and wireless controls. This allowed the units to be incorporated into an adaptive campus-wide lighting control system. The system offers an intelligent, networked approach to lighting and energy management with improved lighting quality and optimal energy efficiency.
The Advanced Energy Retrofit Guide for Grocery Stores was created to help grocery store decision makers plan, design, and implement energy improvement projects in their facilities. It was designed with energy managers in mind, and presents practical guidance for kick-starting the process and maintaining momentum throughout the project life cycle.

The Advanced Energy Retrofit Guide for K-12 Schools is one of five retrofit guides commissioned by the U.S. Department of Energy. By presenting general project planning guidance as well as more detailed descriptions and financial payback metrics for the most important and relevant energy efficiency measures, the guides provide a practical roadmap for effectively planning and implementing performance improvements in existing buildings. The K-12 Schools guide provides convenient and practical guidance for making cost-effective energy efficiency improvements in public, private, and parochial schools.
