Opportunity: Building Energy Efficiency Through Innovative Ther

Buildings consume 40 percent of the primary energy in the United States, and account for 72 percent of the nation's electricity use and 55 percent of the nation's natural gas use. The objective of this funding opportunity announcement is to develop energy efficient cooling technologies/air conditioners (AC) for buildings to reduce GHG emissions from: (a) primary energy consumption due to space cooling; and (b) refrigerants used vapor compression systems. ARPA-E seeks innovative research and development approaches to increase energy efficiency and reduce emissions due to cooling of buildings by: (i) development of cooling systems that use refrigerants with low global warming potential of less than or equal to 1: (ii) development of energy efficient air conditioning (AC) systems for warm and humid climates to increase the coefficient of performance (COP) of ventilation load cooling by greater than or to 50 percent; and (iii) increased efficiency of hot climate vapor compression AC systems for re-circulating air loads by increasing the COP by greater than or equal to 50 percent. One or more combination of these technologies can be utilized in buildings, where many factors influence the cooling load, including but not limited to: (1) type of building, such as office space versus hospitals (which have very high ventilation loads - almost 100 fresh air); and (2) climate type -warm and humid versus hot and dry.
