Incentives for Gas Furnaces in Oregon: Interaction between Energy Trust and the Residential Energy Tax Credit

Date Published: November 1, 2006     Document Type: Evaluation Study / Report, Report

There is a significant overlap in incentives given for energy efficient gas furnaces between two incentive programs in Oregon. Energy Trust of Oregon (ETO) gives an incentive to consumers who purchase an energy efficient gas furnace. In addition, the Oregon Department of Energy provides a tax credit to consumers of efficient furnaces. Consumers in the NW Natural (NWN) service territory are eligible to receive both incentives. The number of consumers who received incentives for gas furnaces with an efficiency rating of at least 90% cannot simply be determined by aggregating the number of participants in each program. This paper presents the findings of the overlap, and supplemental findings ascertained from the available data. 

Evaluating Commercial Building Electricity Intensity: Leveraging National and Local Surveys (Abstract Only)

Date Published: January 1, 2005     Document Type: Conference publication

The main purpose of this research project was to develop a method for forecasting Pacific Northwest (PNW) commercial sector retail electricity sales using the Northwest Energy Efficiency Alliance's (the Alliance) Commercial Building Stock Assessment (CBSA) survey, completed in 2003, in conjunction with national data collected by the Energy Information Administration's (EIA) quadrennial Commercial Building Energy Consumption Survey (CBECS). Exploiting the CBECS database offers energy planners several potential benefits, among them reducing the costs and effort associated with undertaking periodic large-scale commercial building surveys, increasing the frequency with which energy sales forecasts are made using building microdata, and aiding in an understanding of the relationship between national and regional energy consumption trends. In addition, comparing regional trends with national trends provides regional policymakers with another method for evaluating, in aggregate, the impacts of regional energy efficiency programs.

An Era of Energy Efficiency in the Commercial Sector: Investigation and Findings (Abstract Only)

Date Published: January 1, 2003     Document Type: Conference publication

The paper describes the specification and estimation of an energy demand model that focuses on electricity use in the U.S. commercial sector from 1989 to 2000. The panel model is designed to separate state effects and market-driven effects from energy efficiency program effects, thereby obtaining long-run estimates of the impact of commercial sector energy efficiency programs, including DSM and market transformation programs, on national energy use. The preliminary finding of this study is that publicly-funded energy efficiency programs have had a discernable impact on annual electricity demand. (Abstract only)
