The PIER Demonstration program partnered with the University of California, Davis to demonstrate new construction and retrofit design strategies that provide dual light levels based on occupancy sensing that is appropriate for the interior corridor application. 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.

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.
The California Energy Commission’s Public Interest Energy Research (PIER) Program sponsors the development and demonstration of energy-efficient building technologies. Over the past several years, PIER has developed strategic partnerships with the University of California, California State University, California Community Colleges, and California Department of General Services. These partnerships include a series of demonstration projects coupled with programmatic support to ensure continued deployment of energy-efficient technologies and practices across California. Examples of the latest energy-efficient innovations are described.
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.
Advanced Energy Design Guide for Small to Medium Office Buildings is the first in a series of Advanced Energy Design Guide (AEDG) publications designed to provide recommendations to achieve 50% energy savings when compared with the minimum code requirements of ANSI/ASHRAE/IESNA Standard 90.1-2004, Energy Standard for Buildings Except Low-Rise Residential Buildings (ASHRAE 2004). This guide applies to small to medium size office buildings with gross floor areas up to 100,000 ft2.
