This report summarizes the barriers and recommendations from the five technology working groups of the Commercial Building Consortium (CBC) and is a companion summary analysis to a Commercial Buildings Technology Inventory. In development of the Commercial Buildings Technology Inventory, the CBC examined existing information sources, including published and gray literature, DOE and National Laboratory plans, industry-sponsored research programs, utility research on emerging technologies, and other sources. The CBC recognizes that there are still remaining gaps in the inventory to address in subsequent annual updates. A related technology screening effort currently underway through DOE and the National Labs. The CBC intends to provide industry input into that process and build off of results from that technology screening to further enhance a comprehensive next-generation technologies inventory.
