This design sourcebook provides sixty-seven best practices for optimizing energy efficiency and facility performance in data centers. The best practices span several categories including airflow management, air handler systems, humidification, plant optimization, and IT equipment selection.
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 describes efforts to develop a computerized tool that can rapidly execute and evaluate many building energy simulations. Building energy simulations are often used for trial-and-error evaluation of “what-if” options in buildingdesign—a limited search for an optimal solution, or “optimization.” Computerized searching has the potential to automate the input and output, evaluate many options, and perform enough simulations to account for the complex interactions among combinations of options.
Commercial buildings have a significant impact on energy use and the environment. They account for approximately 18% (17.9 quads) of the total primary energy consumption in the United States (DOE 2005). The energy used by the building sector continues to increase, primarily because new buildings are added to the national building stock faster than old buildings are retired. Energy consumption by commercial buildings will continue to increase until buildings can be designed to produce more energy than they consume. As a result, the U.S. Department of Energy's (DOE) Building Technologies Program has established a goal to create the technology and knowledgebase for marketable zero-energy commercial buildings (ZEBs) by 2025.
