To meet ambitious goals such as 100% clean energy, cities must address building performance. This requires cities to mobilize the many organizations and individuals that influence building energy use in their jurisdiction. To change the day-to-day business practices of these individuals and organizations, city governments first need to understand the various market actors’ attitudes, interests, and challenges with respect to energy efficiency. IMT’s Energy Opportunity Scan helps cities gain a deeper understanding o how these market actors view energy efficiency. This short PDF provides an overview of the Energy Opportunity Scan.
