Federal Energy and Water Management: Agencies Report Mixed Success in Meeting Efficiency Requirements, and Additional Data Are Needed

Fast Facts

For decades the federal government has worked to improve energy and water efficiency at federal facilities. It remains the U.S.'s single largest energy consumer, and occupants of its about 350,000 buildings used 119 billion gallons of water in FY 2021.

We looked at data for 27 agencies that report their energy and water use to the Department of Energy and their compliance with 6 energy and water requirements. But, we couldn’t tell if 3 requirements were met because data wasn't tracked or wasn't available.

We recommended that DOE improve its data tracking and determine whether agencies are implementing required efficiency measures on time.

Highlights

What GAO Found

According to data from fiscal year 2021, federal agencies have a mixed record meeting the six energy and water efficiency requirements that GAO reviewed. There are 27 agencies that use the Department of Energy (DOE) Compliance Tracking System to report data on their performance in meeting these requirements. These data show that most agencies met, or almost met, two of the requirements and did not meet one requirement. GAO could not determine whether agencies fully met the other three requirements due to a lack of data, either because the implementation deadline had not passed and there were not yet available data, or because DOE does not track performance (see table).

Specifically, DOE does not track whether agencies entered water use data into a benchmarking system or followed up on implemented energy and water efficiency and conservation measures (ECM) within 4 years, as called for by DOE guidance. As a result, decision makers cannot be certain that agency officials are benchmarking water use data and measuring energy and water savings from implemented ECMs. Without tracking performance on these requirements, Congress cannot know the extent to which agencies have the data they need to make effective decisions to improve energy and water efficiency.

Note: Data are as of August 24, 2022. This table summarizes relevant requirements from 42 U.S.C. § 8253(f) and DOE guidance. For more details, see table 1 in this report.

Officials GAO interviewed from selected agencies cited varied successes and challenges to meeting each of the six requirements, but the two most frequently cited were the success of using automated or centralized data and the challenge of insufficient resources. For example, agency officials told GAO that automated data allowed them to automatically upload data into a benchmarking system, rather than entering the data manually. Conversely, officials told GAO that insufficient funding or staffing made meeting the requirements challenging. Officials from one agency explained that they must conduct evaluations at agency facilities in remote locations. This makes evaluations more resource-intensive because of the time and expense of sending staff to those locations.

Why GAO Did This Study

The federal government is the single largest energy consumer in the United States. In fiscal year 2021, its roughly 350,000 buildings used more than 344 trillion Btu of energy and 119 billion gallons of water, according to DOE data. For decades, the federal government has taken steps to improve energy and water efficiency at federal facilities, including through laws and executive orders. In particular, six requirements from section 432 of the Energy Independence and Security Act of 2007, as amended, relate to the use of energy and water efficiency measures in federal facilities.

GAO was asked to review issues related to agency compliance with these energy and water efficiency requirements. This report examines (1) the extent to which agencies are complying with the six energy and water efficiency requirements and (2) the successes and challenges that selected agencies have encountered in their efforts toward meeting these requirements.

GAO reviewed DOE data on agency performance in meeting requirements; interviewed officials from six federal agencies, selected in part for facility size and energy use; and conducted a literature review.

Recommendations

GAO recommends that DOE track performance toward meeting the requirements from DOE guidance to (1) enter water use data into a benchmarking system and (2) follow up on implemented energy and water efficiency and conservation measures within 4 years. DOE concurred with GAO's recommendations.

Recommendations for Executive Action

Agency Affected Recommendation Status
Department of Energy The Secretary of Energy should update the Compliance Tracking System to track performance toward meeting the requirement in DOE's guidance to enter water use data into a benchmarking system for buildings that are metered for water use. (Recommendation 1)
Closed – Implemented
As of June 2023, the Department of Energy updated the Compliance Tracking System to track performance toward meeting the requirement in DOE's guidance to enter water use data into a benchmarking system for buildings that are metered for water use. Data for covered agencies may be found online in the Benchmarked Buildings report within the Compliance Tracking System.
Department of Energy The Secretary of Energy should update the Compliance Tracking System to track performance toward meeting the requirement in DOE's guidance to follow up on implemented energy and water efficiency and conservation measures within DOE's required 4-year time frame. (Recommendation 2)
Closed – Implemented
As of June 2023, the Department of Energy updated the Compliance Tracking System to track performance toward meeting the requirement in DOE's guidance to follow up on implemented energy and water efficiency and conservation measures within DOE's required 4-year time frame. Data for covered agencies may be found online in the Initiated Projects report within the Compliance Tracking System.
