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.

This paper illustrates the challenges of integrating rigorous daylight and electric lighting simulation data with whole-building energy models, and defends the need for such integration in order to achieve aggressive energy savings in building designs. Through a case study example, we examine the ways daylighting – and daylighting simulation – drove the design of a large net-zero energy project.
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 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 conference paper discusses four well-documented definitions of net-zero energy: net-zero site energy, net-zero source energy, net-zero energy costs, and net-zero energy emissions, along with pluses and minuses of each.
This paper introduces a classification system for net-zero energy buildings (ZEB) based on the renewable sources a building uses.
This document was developed as part of the LED Application Series. Light-emitting diode (LED) technology is rapidly becoming competitive with high-intensity discharge light sources for outdoor area lighting. This document reviews the major design and specification concerns for outdoor area lighting, and discusses the potential for LED luminaires to save energy while providing high-quality lighting in outdoor areas.
This document provides information on the application of the CBEA site lighting performance specification at some U.S. Department of Energy (DOE) GATEWAY demonstration projects. Because the issues and experiences from the applications vary, this document’s summarization and comparison of the results helps to show the benefits and caveats of an LED application. It also offers guidance for planning an LED application.
The Federal Energy Management Program (FEMP) Outdoor SSL Initiative encourages the federal sector to lead a large-scale implementation effort focused on Solid State Lighting (SSL) application. This fact sheet provides an overview of existing outdoor SSL resources developed by the U.S. Department of Energy’s SSL Program and other federal initiatives, as well as general SSL resources.
This report considers the major potential for lighting-related energy savings for all major exterior areas, including parking lots, streets and roadways, and building-mounted lighting. Discussion covers safety and security challenges that could hinder maximum energy savings. The report discusses the need for good design features—including appropriate lighting levels—that support safety and security elements, such as visual identification capability and effective lighting for security cameras. Lighting issues related to litigation concerns also are part of this reports.
