A zero net energy (ZNE) building is a home or commercial building that on average produces as much energy as it uses, achieved through energy efficiency and renewable technologies. Building energy codes can help us transition to ZNE construction for new residential and commercial buildings by 2030. We will need to expand the scope of codes to capture all building energy uses, address whole building systems instead of focusing on individual components, and shift our focus from building design to actual building energy use by adopting outcome-based codes. We should also ensure ZNE performance post-occupancy by considering the impact of building occupants and operators and by incorporating future-proofing measures. By addressing these areas, we can establish the foundation for ZNE by 2030 while providing energy savings and related benefits in the interim. Complementary policies, targeted research, market transformation, and the coordination of efforts and advocacy will help us achieve these goals.

Expanding the Energy Efficiency Pie: Serving More Customers, Saving More Energy Through High Program Participation

This report analyzes ten categories of utility-sector energy efficiency programs that have achieved high participation among targeted customer markets. Despite issues with the nature and availability of participation data, the study draws on published data sources and interviews with program contacts and industry experts to identify many examples of programs that have achieved high participation. Programs serving mass markets, such as residential customers shopping for lighting products, can move millions of products annually and penetrate 40% of the market. Some programs providing custom incentives to the largest commercial and industrial customers have achieved 50-70% participation over several years. Leading new commercial construction programs may reach 50-60% of all new projects. The report examines and analyses key factors that contribute to high participation within each of the ten selected program categories. The research reveals that an ever-growing number of utility customers are already participating in energy efficiency programs, and many more could participate.

For the past eight years, the ACEEE State Energy Efficiency Scorecard has measured the progress of state policies and programs that save energy while also benefiting the environment and promoting economic growth. Using data vetted by state energy officials, we rank states in six categories—utility programs, transportation, building energy codes, combined heat and power, state initiatives, and appliance standards. In this eighth edition of the State Scorecard, Massachusetts secured the top spot for the fourth year in a row. Joining Massachusetts in the top five were California, Rhode Island, Oregon, and Vermont. The most-improved states in 2014 were Arkansas, the District of Columbia, Kentucky, and Wisconsin. Indiana and Ohio, meanwhile, fell the furthest in the rankings due to decisions by legislators in both states to roll back energy savings targets. Despite setbacks in these states, energy efficiency has remained a key resource, with utilities budgeting more than $7.7 billion in 2013 for efficiency programs across the country.

Examining the Net Savings Issue: A National Survey of State Policies and Practices in the Evaluation of Ratepayer-Funded Energy Efficiency Programs

Determining the net savings impacts of a program is one of the most prominent and longstanding challenges in the utility energy efficiency field. ACEEE conducted a national review of state approaches to the net savings issue in order to help policymakers, regulators, utilities, and other interested parties better understand this issue and how their peers are addressing it. We surveyed all 50 states and the District of Columbia, reviewed recent industry literature, and conducted interviews with national energy efficiency program evaluation experts.

The purpose of this study was not to assess or recommend particular evaluation methodologies, but to examine and document states’ decision making on the issue of net savings.

The results of this project indicate a great deal of diversity in how states are approaching this issue. At one end, nearly a quarter of states simply report gross savings. Another large segment, probably a majority, nominally report net savings, but with a fairly simplistic approach (often just using deemed net-to-gross ratios). Finally, a small number of states (many profiled in this report) are pursuing more complex approaches to measuring net savings, including spillover and in some cases, broader market effects.

The report provides a summary of our national survey results, state-by-state results on key variables, the takeaways from our interviews with national energy efficiency evaluation experts, profiles of some noteworthy states, our overall conclusions, and a few practical recommendations for how states should address various aspects related to the subject of net savings.

From press release:

The American Council for an Energy-Efficient Economy (ACEEE) today released the 2013 City Energy Efficiency Scorecard, a report that ranks 34 of the most populous U.S. cities on policies to advance energy efficiency. The report includes recommendations and strategies for all cities to lower energy use. ACEEE also launched a new interactive infographic accompanying the report that highlights each city’s best practices and scores.

Boston took top honors, doing the most to save energy. Other top-scoring cities include Portland, Ore., New York City, San Francisco, Seattle and Austin. The next tier of top-scoring cities (Washington, D.C., Minneapolis, Chicago, Philadelphia and Denver) have also developed efficiency initiatives and are poised to rise in the rankings in future years.

The long-term energy efficiency potential: What the evidence suggests

America is thinking too small when it comes to energy efficiency, while also making the mistake of “crowding out” economically beneficial investments in energy efficiency by focusing on riskier and more expensive bids to develop new energy sources, according to a major new report from the American Council for an Energy-Efficient Economy (ACEEE).

Titled The Long-Term Energy Efficiency Potential: What the Evidence Suggests, the new ACEEE report outlines three scenarios under which the U.S. could either continue on its current path or cut energy consumption by the year 2050 almost 60 percent, add nearly two million net jobs in 2050, and save energy consumers as much as $400 billion per year (the equivalent of $2600 per household annually).

According to ACEEE, the secret to major economic gains from energy efficiency is a more productive investment pattern of increased investments in energy efficiency, which would allow lower investments in power plants and other supply infrastructure, thereby substantially lowering overall energy expenditures on an economy-wide basis in the residential, commercial, industrial, transportation, and electric power sectors.

Greening Work Styles: Analysis of Energy Behavior Programs in the Workplace

January 17, 2012 Comments off
Source:  American Council for an Energy-Efficient Economy
This report focuses on energy behavior programs in the workplace, which aim to reduce building energy use through change in employees’ attitudes and behaviors. The report reviews five energy behavior projects across the U.S. and Canada. Energy savings of the studied energy behavior projects are from 4% (savings from a stand-alone behavior program) to nearly 75% (savings from a comprehensive project in which a behavior program is a component).
The report also identifies four intervention strategies shared by the reviewed energy behavior projects: (1) setting the tone with strong support from upper management and good program branding; (2) building a team consisting of a stakeholder-oriented program committee and peer champions selected from building occupants; (3) employing communication tools including e-mail, Web sites, prompts, posters and public meetings; and (4) deploying key engagement techniques such as feedback, benign peer pressure, competition, rewards, and reference to appropriate social norms.
