Select RMI Projects

  • Solar Soft Costs – Koben has contributed and lead efforts to engage industry partners in collecting data, analyzing cost drivers, and identifying the best, near-term opportunities for cost reduction. A current project, the SIMPLE Balance of System (BoS) project, is a partnership between Rocky Mountain Institute (RMI) and Georgia Tech Research Institute (GTRI) to better understand the cost drivers of rooftop PV and identify opportunities for cost reduction.
  • Community Emissions Reduction Roadmap – Koben was the primary lead and content contributor on the transportation analysis component of a comprehensive plan to achieve carbon neutrality at Arizona State University (ASU). ASU partnered with Ameresco Inc. and Rocky Mountain Institute to craft an implementation plan for campus climate neutrality by 2025 and transportation neutrality by 2035.
