This report presents the results of a comprehensive market research study (the Study) focused on the commercial and industrial (C&I) lighting industry of the Pacific Northwest (PNW) conducted on behalf of the Northwest Energy Efficiency Alliance (the Alliance). The information and recommendations presented in this report will aid the Alliance in determining whether to develop a set of initiatives tailored to the unique needs of the region’s C&I lighting market. Although the scope of this study includes only research on C&I lighting, readers should be aware that the Alliance is analyzing whether C&I lighting should be addressed through lighting-specific initiatives, lighting-related activities that are integrated parts of a broader whole-building initiative, or some combination of the two. Also note that the research presented in this report is intended by the Alliance to be a broad first-step effort from which additional market research efforts may follow.
