Home Energy Rebate Program Energy Efficiency Measures Review

The Home Energy Rebate Program retrofitted nearly 27,000 homes in Alaska, saving Alaskans $261 million in energy costs and reducing greenhouse gas emissions by more than 3 billion pounds from 2008 to 2018. This project analyzed which energy efficiency measures were actually implemented in this program for the first time, providing valuable information for contractors, organizations dealing in home energy, and policymakers. Three reports were created as a part of this analysis:

Energy Efficiency Measures Implemented in the Home Energy Rebate Program: This report highlights which efficiency measures were implemented statewide through the program and provides recommendations for the future. It includes Appendix A, which provides regional summary of which energy efficiency measures were implemented in different areas of the state.

The following two reports are geared toward energy researchers:

Installed Costs of Energy Efficiency Measures in the Home Energy Rebate Program: A Multivariate Regression Analysis: This analysis attempted to use a multivariate regression analysis to determine the installed cost of energy efficiency measures implemented through the Home Energy Rebate Program. Due to a variety of confounding factors, results were mixed, with only six measures having statistically relevant cost ranges.

Natural Gas Savings from Energy Efficiency Measures in the Home Energy Rebate Program: A Multivariate Regression Analysis: This analysis was done to try to estimate the actual natural gas savings from energy efficiency measures implemented through the Home Energy Rebate Program. Natural gas data from Enstar was matched to homes that participated in the program and a multivariate regression analysis was performed to try to tease out savings from individual measures, with mixed success.
