The 2012 ACEEE Summer Study is the 17th 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, actions to reduce energy use and the climate impacts associated with buildings. Presentations and discussions will relate to the theme, “Fueling Our Future with Efficiency.” Global activities related to building energy efficiency and sustainability have received increased attention worldwide in recent years, in order to avoid the worst consequences of climate change, while also addressing the problems of energy security and resource depletion. To progress towards an energy-efficient and sustainable future, the pace of investment in, and implementation of, energy use reduction strategies must be greatly accelerated. Well integrated government and utility programs, codes and standards, technologies, integrated design processes, operation practices and financing sources need to be further developed and cost-effectively implemented, while addressing behavioral factors and workforce development needs. A new generation of multi-disciplinary practitioners, researchers, and policymakers needs to be educated and quickly deployed to solve the closely-coupled energy efficiency and climate problems that we face. Come to the 2012 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.
