Updated Buildings Sector Appliance and Equipment Costs and Efficiency

Released: August 7, 2013

The Energy Information Administration (EIA) works with technology experts to project the cost and efficiency of future heating, ventilation, and air-conditioning (HVAC), lighting, and other major end-use equipment rather than developing residential and commercial technology projections in-house. These reports have always been available by request. By providing the reports online, EIA is increasing transparency for some of the most important assumptions used for our Annual Energy Outlook projections of buildings energy demand.

 
Distributed Generation System Characteristics and Costs in the Buildings Sector

Released: August 7, 2013

The Energy Information Administration (EIA) works with technology experts to project the cost and performance of future residential and commercial sector photovoltaic (PV) and small wind installations rather than developing technology projections in-house. These reports have always been available by request. By providing the reports online, EIA is increasing transparency for the assumptions used for our Annual Energy Outlook buildings sector distributed generation projections.
