The California Energy Commission’s Public Interest Energy Research (PIER) program sponsored development of bi-level parking garage luminaires for the University of California, Davis that integrate intelligent controls with bi-level electronic drivers or ballasts to control light output based on garage occupancy. Luminaires operate at a reduced level during vacancy and switch to full light output upon occupancy. Many of the products may be combined with traditional photocontrols to maximize energy savings.

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 Advanced Energy Design Guide for Large Hospitals shows that existing reliable technologies and design philosophies can be used to reduce energy use in large hospitals by up to 50% of ANSI/ASHRAE/IESNA Standard 90.1-2004 recommendations.
The Advanced Energy Design Guide for Small Hospitals and Healthcare Facilities can help in the design of new healthcare facilities that are 30% more energy efficient than current industry standards using ANSI/ASHRAE/IESNA Standard 90.1-1999 as a benchmark. This saves energy but also supports the other design goals important to healthcare facilities: to improve the patient experience, enhance the healing environment, increase staff retention, lower construction and operating costs, contribute to an environmentally conscious building design, and improve the bottom-line performance of the healthcare facility.
This guide was created to help healthcare facility 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.
It is still early in the collection and analysis of energy performance data, but it is already clear that high-performance commercial buildings—some "almost net-zero buildings"—can be constructed cost effectively, providing productive environments for occupants, reducing operating costs, and enhancing the competitiveness of commercial properties.
This document provides an example request for proposal (RFP) for a Department of Energy (DOE) and National Renewable Energy Laboratory (NREL) Ingress/Egress Project with a Site Entrance Building and Parking Structure. The RFP has been annotated by NREL to demonstrate the project’s steps that follow NREL and DOE’s Energy-Performance-Based Acquisition process.
This guide provides design teams with best practices for parking structure energy efficiency in the form of goals for each design aspect that affects energy use.
This paper describes how net-zero energy buildings will produce, during a typical year, enough renewable energy to offset the energy they consume from the grid.
This paper introduces a classification system for net-zero energy buildings (ZEB) based on the renewable sources a building uses.
