Best Available Technologies in the U.S. Buildings Sector

PNNL developed this list in collaboration with DOE under the Top Tens Task Group of the International Partnership for Energy Efficiency Cooperation (IPEEC). This list highlights energy savings technologies for the American buildings sector that are innovative, reliable, widely available, and have good financial value.

This list can be used by both energy consumers to consider the benefits of these technologies and to producers of these technologies to promote their products. While this list is focused on technologies most relevant to the U.S. buildings sector, American companies may also use this list to promote their products both domestically and abroad.

About 40% of total U.S. energy consumption in 2016 was consumed by the residential and commercial sectors. The scope of building technologies included those that affect energy demand for heating (including water), cooling, and lighting, which in sum account for more than 60% of energy demand in both commercial and residential buildings. Please see here for more information on the methodology, which included energy modeling using BTO’s Scout tool.

Industry

The industrial sector uses more delivered energy than any other end-use sector, consuming about 54% of the world’s total. In the U.S., industry accounts for about one-third of the energy used.

A list of technologies for the American industry sector was created in 2015 under the same task group by the Lawrence Berkeley National Laboratory (LBNL). Here is the full report for the United States’ list of technologies in this sector. Additionally, Australia, China, Japan, and the United States collaborated to create an international list of best available technologies and practices in the industrial sector.
