In March 2013, the Northwest Energy Efficiency Alliance (NEEA) commissioned Cadmus and subcontractors Energy350 and Nexant (hereafter known as the Cadmus team) to conduct the Industrial Facility Site Assessment (IFSA). The primary goal of the IFSA was to obtain end-use energy consumption data for the Northwest industrial population. The IFSA was intended to provide: (1) a comprehensive and regionally representative account of energy usage characteristics in Northwest industrial facilities; and (2) a comprehensive analysis of the levels, use, and management of industrial energy. To the best of our knowledge, the IFSA was the first study in the United States to collect this type of comprehensive information on this level. Because of the unprecedented nature of this work, the project experienced a variety of challenges related to outreach, recruitment, and analysis, which are detailed throughout the report.
