The 2010 ACEEE Summer Study is the 15th biennial ACEEE conference on Energy Efficiency in Buildings. A diverse group of professionals from around the world will gather at this preeminent meeting to discuss the technological basis for, and practical implementation of, reducing energy use and climate impacts associated with buildings. Presentations and discussions will relate to the theme, “The Climate for Efficiency is Now.” Global activities related to energy efficiency in buildings are rapidly expanding, in part to stimulate world economies, but also to avoid the worst consequences of climate change and resource depletion. To achieve its full potential, however, this energy efficiency “engine” needs to address sustainable development and climate issues that go beyond buildings. Well integrated programs, technologies, and financing sources need to be developed. A new generation of multi-disciplinary practitioners, researchers, and policymakers needs to be trained and quickly deployed to solve the closely-coupled energy efficiency and climate problems that we face. Come to the 2010 Summer Study, where you can share your ideas and engage in dialogue with leading thinkers, visionaries, and luminaries in the field, while experiencing the magnificent natural setting of Asilomar Conference Grounds.
