Voluntary government programs such as ENERGY STAR have been created to promote energy efficiency within different organizations and businesses, and this study is dedicated to discovering whether or not businesses that become certified building partners with ENERGY STAR obtain a competitive advantage. Through two different methods of analysis, an observational analysis and a test of means, data on profitability ratios from twenty-five ENERGY STAR partners are examined to determine if partnering with ENERGY STAR results in a competitive advantage.
