This session will focus on several examples of ex post evaluations completed for a range of energy related policies and programs. The first was completed for a utility in Switzerland, SIG (“Services Industriels de Genève”), and focuses on the results from an evaluation of a ongoing program named “Communs d’Immeuble,” which is intended to encourage energy savings in communal areas of existing buildings, mainly through the installation of common area lighting measures (hall, corridors, stairs, cellars, garage, etc.), as well as other equipment (fans, pumps, lifts, common laundry, etc.). The evaluation utilized multiple methods, including counterfactual analyses, bottom-up and top-down approaches, and the use of parametric and non-parametric models.
This second paper focuses on a comprehensive evaluation of the U.S. Department of Energy’s (USDOE) four-year, $500 million stimulus-policy-funded Better Buildings Neighborhood Program (BBNP). An innovative initiative exploring the potential for different marketing strategies and program designs to encourage building energy upgrades resulting in significant energy savings and economic stimulus, this program was geographically diverse in scope (i.e., included 41 US state and local governments), and offered grants, incentives and other types of financing options to a range of end-user groups (e.g., single-family residential, multifamily residential, low income, commercial, and agricultural). The evaluation determined estimates of energy savings from the program using two primary methods: (1) regression modeling to identify changes in energy use resulting from efficiency retrofits, and (2) engineering analyses for a sample of projects. The evaluation also included site visits to verify installation and measure conditions, desk reviews of retrofit documentation, and interviews and phone surveys with participants. Finally, the evaluation also included input-output analysis to determine the macro economic impacts of the program.
The third paper focuses on ex post evaluations of a range of energy and carbon tax schemes. The paper includes a descriptive summary of the specific characteristics of these schemes, such as the targeted sectors, the participants, the tax rate and the resulting evidence of a reduction in greenhouse gas emissions. It also presents the results from a literature review on existing ex post evaluations, comparing different methods and identifying data needed for robust interpretation of the impacts of these tax schemes. Finally, the paper discusses some of the limitations of these types of energy and carbon tax evaluations (e.g., selection bias problems) and offers recommendations for improving research activities going forward.
