2012 CBECS Preliminary Results

Released: June 19, 2014

The preliminary results from the Commercial Buildings Energy Consumption Survey (CBECS) show that there were 5.6 million commercial buildings in the United States in 2012, comprising 87.4 billion square feet of floorspace.

PDF Analysis and Representation of Miscellaneous Electric Loads in NEMS

Released: January 6, 2014

Miscellaneous Electric Loads (MELs) comprise a growing portion of delivered energy consumption in residential and commercial buildings. Recently, the growth of MELs has offset some of the efficiency gains made through technology improvements and standards in major end uses such as space conditioning, lighting, and water heating. Miscellaneous end uses, including televisions, personal computers, security systems, data center servers, and many other devices, have continued to penetrate into building-related market segments. Part of this proliferation of devices and equipment can be attributed to increased service demand for entertainment, computing, and convenience appliances.

PDF Modeling Distributed Generation in the Buildings Sectors

Released: August 29, 2013

This report focuses on how the Energy Information Administrationmodels residential and commercial sector distributed generation, including combined heat and power, for the Annual Energy Outlook.

PDF 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.

PDF 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.

Water Data Collection in the 2007 CBECS

Released: August 28, 2012

The 2007 round of the Commercial Buildings Energy Consumption Survey (CBECS) was the first time in the 30 year CBECS history that questions about water consumption were asked of respondents. The Energy Information Administration (EIA), in cooperation with the Environmental Protection Agency (EPA), added these questions to the CBECS because water and energy consumption are connected in many ways.

Large Hospital Buildings in the United States in 2007

Released: August 17, 2012

Hospitals consume large amounts of energy because of how they are run and the many people that use them. They are open 24 hours a day; thousands of employees, patients, and visitors occupy the buildings daily; and sophisticated heating, ventilation, and air conditioning (HVAC) systems control the temperatures and air flow. In addition, many energy intensive activities occur in these buildings: laundry, medical and lab equipment use, sterilization, computer and server use, food service, and refrigeration.

PDF Commercial Buildings Energy Consumption Survey - Office Buildings

Released: September 29, 2010

Provides an in-depth look at this building type as reported in the 2003 Commercial Buildings Energy Consumption Survey. Office buildings are the most common type of commercial building and they consumed more than 17% of all energy in the commercial buildings sector in 2003. This special report provides characteristics and energy consumption data by type of office building (e.g. administrative office, government office, medical office) and information on some of the types of equipment found in office buildings: heating and cooling equipment, computers, servers, printers, and photocopiers.

Lighting in Commercial Buildings

Released: April 15, 2009

Lighting is a major consumer of electricity in commercial buildings and a target for energy savings through use of energy-efficient light sources along with other advanced lighting technologies. The Commercial Buildings Energy Consumption Survey (CBECS) collects information on types of lighting equipment, the amount of floorspace that is lit, and the percentage of floorspace lit by each type. In addition, CBECS data are used to model end-use consumption, including energy consumed for lighting in commercial buildings. (archived versions)

PDF Overview of Commercial Buildings, 2003

Released: December 23, 2008

The Energy Information Administration conducts the Commercial Buildings Energy Consumption Survey (CBECS) to collect information on energy-related building characteristics and types and amounts of energy consumed in commercial buildings in the United States.

PDF Commercial Buildings Energy Consumption Survey 2003 - Detailed Tables

Released: September 1, 2008

The tables contain information about energy consumption and expenditures in U.S. commercial buildings and information about energy-related characteristics of these buildings.

Computers and Photocopiers in Commercial Buildings

Released: August 12, 2002

Use of computers and photocopiers in commercial buildings, based on 1999 Commercial Buildings Energy Consumption Survey data.

Look at Building Activities in the 1999 Commercial Buildings Energy Consumption Survey, A

Released: July 24, 2002

Profiles of commercial building types, including office buildings, shopping malls, hospitals, churches, and fire stations. Data from the 1999 Commercial Buildings Energy Consumption Survey.

Trends in the Commercial Buildings Sector

Released: January 12, 2000

Trends in number of buildings, amount of floorspace, and energy consumption from 1979 to 1999.
