Local governments aiming to reduce their city’s energy usage might begin by writing a strategic energy management plan for the local government operations. Within this plan, an energy usage reduction goal should be established. We call planning and goal setting of this nature “leading by example.” By practicing energy efficiency and environmental stewardship across city operations, highly localized best practices may be developed for adoption by managers of single buildings or building portfolios within the city.
This memo provides guidance to an energy or environmental manager of a local government establishing a goal for reducing municipal energy use. This memo is most useful if the local government has begun using a building benchmarking software for a year or longer. To help an adopting city develop a goal that meets its needs, we present and discuss best practices in setting energy management goals. We also describe a variety of existing goal-setting platforms, which the city could use in its efforts. We end by describing some specific recommendations for an adopting city.
To meet the needs of a city, its policymakers, and its staff, we recommend that the energy usage reduction goal reflect four criteria:
There are many factors to consider in goal setting. One way to organize the important considerations for goal setting is the five-criteria SMART acronym. SMART goals related to energy use should be specific, measurable, attainable, relevant, and time-bound.
Specific. The goal should be detailed enough to achieve its purpose, yet clear and easy to understand. To ensure specificity, we recommend the following.
Measurable. A goal cannot be achieved if it is not measured. The first step is institutionalizing an energy usage tracking system and collecting past data. A local government that has taken this step is poised and ready to achieve the “measurability” factor.
Attainable. It is difficult to motivate action if a goal is too aspirational to be achieved or too weak to make a difference. A local government should set a target that is meaningful, yet challenging to achieve. We recommend the following considerations to determine an attainable goal.
Table 1. Energy savings plans, target annual reductions, and actual reductions of four peer communities.
Relevant. The energy management goal should be in line with a city’s overall vision. An energy reduction goal helps a city achieve many benefits such as energy and cost savings and emission reductions. An appropriate goal enables short-term success and helps to build a foundation for long-term improvements in energy management.
Time-bound. A goal exists within a time frame. A baseline year sets the standard by which progress is measured and the target year bounds the end point of the goal. Along the way, mid-term targets can help progress stay on track and manage feasibility. If a mid-term target is missed or exceeded, program implementation (or the end goal) may need adjustment.
Local governments can choose among a variety of existing platforms to develop and adopt energy management goals. These platforms can be valuable because they provide a standardized approach to goal development and management. They also often provide related technical resources and access to a network of other communities pursuing similar goals.
U.S. Department of Energy’s Better Buildings Challenge (Focus: energy use in buildings relative to building area). The Better Buildings Challenge is a partnership between the Department of Energy and private and public organizations from many sectors, including local governments. In this program, each partner pledges to reduce energy usage intensity (EUI) across its building stock by a minimum of 20% over 10 years and to share its strategies and results. As of spring 2014, participants had averaged a 2.5% improvement in EUI annually. [8] The process begins with a building stock assessment and an identification of energy efficiency opportunities. Next, the members complete a showcase project and share the data and tools used to achieve energy savings. During the 10-year span, DOE supports the partner through technical assistance, connects the leaders to a network of peers and allies, and continually recognizes partners for their successes.
Alliance to Save Energy’s Energy 2030 (Focus: energy use relative to economic activity). The Alliance Commission on National Energy Policy developed a goal and roadmap to double U.S. energy productivity (the economic output per unit of energy used) by 2030. The Energy 2030 campaign encourages adoption of the goal by federal, state, and local governments. To achieve the goal, the campaign suggests three strategy areas: unleashing investment, modernizing regulations, and educating and engaging the public.
Architecture 2030’s 2030 Challenge for Planning (Focus: level of carbon-based energy use in buildings and community-wide). Architecture 2030 aims to enable a transition in the construction market so that by 2030 new buildings and existing buildings undergoing major renovations use zero greenhouse gas–emitting energy. Additionally, for existing buildings and neighborhoods, the 2030 Challenge aims for a 50% reduction in energy and water use in buildings and transportation. To get there, it establishes three five-year incremental goals for 2015, 2020, and 2025. Architecture 2030 offers many tools and resources to educate its adopters in implementing energy-saving design strategies and procuring or generating renewable power. The 2030 Challenge was endorsed by the U.S. Conference of Mayors ( Resolution #50) in June 2006. Of the peer communities, Austin, TX, is a signatory. Public-private partnerships in Seattle, Cleveland, and Pittsburgh have developed 2030 Districts to help them achieve these goals.
U.S. Conference of Mayors’ Climate Protection Agreement (Focus: level of community-wide greenhouse gas emissions). In 2005, the U.S. Conference of Mayors presented the Climate Protection Agreement, which aims to enable local governments to help the United States achieve reductions called for in the Kyoto Protocol (7% reduction in greenhouse gas emissions from 1990 levels by 2012). Though this agreement lapsed in 2012, the framework is still a useful reference. In the end, 1,060 mayors have signed on, including Mayors Wynn from Austin, Funkhouser from Kansas City, Gonzales from San Jose, and Menino from Boston. Among other goals, the agreement urges signatories to inventory emissions in city operations, make energy efficiency a priority, and increase fuel efficiency in municipal fleet vehicles. Many communities have used the agreement as a platform to develop localized plans and goals. In 2009, the Mayors’ Climate Protection Center released a report of best practices.

State-level Energy Efficiency Resource Standards (EERS) (Focus: percentage of utility energy savings relative to demand). Twenty-five states have policies that establish specific energy-savings targets for utility-sector energy efficiency programs over a multiyear period. When annualized, these savings targets range from 0.2% to 2.6% per year. While these are state policies, they may also be relevant to local governments interested in developing energy-savings targets because they provide an example based on comparing measured savings from efficiency investments with actual consumption. A recent ACEEE report finds that states with these policies are largely on track to meet their targets. [9]
Based on the objectives of the draft Strategic Energy Management Plan and the considerations presented in this memo, we offer the following recommendations.
Establish an energy intensity or use reduction goal at levels demonstrated as achievable. The five above peer communities have established a 3% annual energy or greenhouse gas reduction goal, on average, and have been able to realize a 5.5% average annual reduction. Participants in the Better Buildings Challenge have committed to a 2% average annual reductions in energy intensity over a 10-year span. To date, participants have achieved average annual reductions of 2.5%. If a local government has achieved past energy savings, the new goal should be considered with a mind to those savings.
Develop a goal for a 10+-year period using multiple benchmark years. A mid- to long-term goal is important to foster a culture of continuous energy improvement, but nearer-term goals are also important for tracking progress. We therefore recommend a goal time frame of 10 years or more, which includes at least one interim goal in addition to the end-year goal. This will enable annualized progress to be measured every year, but with less need for concern about inter-year variation and not hitting the target in some years. If a goal for a 10-year period is adopted, it could read along the lines of, “Reduce energy usage intensity in operations, facilities, and fleets by 10% by 2018 and 25% by 2023 from a 2013 baseline.”
Adopt a single “normal” baseline year. We recommend choosing a baseline year that is representative of an average year. Choose a recent year that saw normal growth, no economic shocks, and average weather patterns. Measuring progress against an abnormal year may make gains look too small or too large to be representative of larger trends.
Assign departmental responsibility. We recommend establishing a lead agency for plan implementation and responsibilities specific to other departments from the beginning. To improve accountability, each of the affiliated departments should be assigned subgoals specific to its efforts and asked to develop plans to meet them.
Collect data to enable normalization. Good energy management practices requires collection of data beyond energy consumption and other energy characteristics. The ability to normalize energy usage in multiple ways is essential to tracking and managing energy use: over account levels, individual buildings, and square footage of buildings. We recommend a city use a software of choice for tracking building energy use data. Additionally, the city should make an effort to collect non-energy data, such as building square footage, to increase the accuracy of EUI figures. Other energy end uses—such as vehicles, outdoor lighting, and water/wastewater—may need even more attention to identify metrics and develop data collection practices that enable accurate normalization.
