Gretchen Schimelpfenig, Technical Director, Resource Innovation Institute


Gretchen is a professional engineer who has spent the past five years optimizing controlled environment agriculture operations for resource efficiency and productivity. Schimelpfenig earned a B.S. in Architectural Engineering from the University of Wyoming and an M.S. in Civil Engineering, Sustainable Design & Construction with a concentration in energy from Stanford University. Her diverse professional experience includes time spent commissioning commercial buildings, designing utility energy efficiency programs, and helping businesses like the University of Vermont and the City of Burlington benchmark their resource consumption. She specializes in analyzing the operation of building systems for cultivation facilities and helps the members of RII’s Utility Working Group reach cultivators with their financial incentives and technical assistance. 

As Technical & Operations Director of RII, Gretchen manages the PowerScore resource benchmarking platform, facilitates RII’s Technical Advisory Council Working Groups and creates curriculum and training to educate producers, efficiency programs, and design and construction communities. She works with members and subject matter experts to publish best practices guidance for production of plants in controlled environments, develops and delivers curriculum, and supports PowerScore users with resource benchmarking analysis and reporting compliance. Schimelpfenig writes for industry publications and is a columnist for GIE Media and Meister Media and publishes in Greenhouse Grower, Greenhouse Management, Cannabis Business Times, and the Cultivation Classroom column for Cannabis Science & Technology. Gretchen grows vine crops and herbs in her veggie garden, greenhouse, and basement in her Vermont farmhouse and is constantly using her HVAC and lighting knowledge to optimize her grow environments.

She works directly with the DesignLights Consortium to increase the adoption of third-party certification of horticultural building systems. Gretchen also represents RII on several industry committees developing standards for CEA including the ASABE PAFS-30 (Plant Systems Group), ES-300 (Electrical Utilization & Energy Group), and ES-310 (Agricultural Lighting Group), ASHRAE Technical Committee 2.2 (Plant and Animal Environments), ASTM Committee D37 on Cannabis, IES Horticultural Lighting Subcommittee, and Task Group 1 of the UL 3600 Scorecard for Measuring and Reporting Circular Economy Aspects of Products, Sites and Organizations.


Derek Smith, Executive Director, Resource Innovation Institute

As Executive Director, Derek provides overall leadership and strategic direction. Derek engages RII’s advisory bodies, including the Strategic Advisory Council and Technical Advisory Council Leadership Committees, develops global partnerships and oversees the organization’s policy work.

Before RII, Derek led Clean Energy Works, recognized as one of the most successful American Recovery & Reinvestment Act ("stimulus") programs. He has directed energy programs for the City of Portland, managed operations for a VC-backed start-up and created an award-winning corporate sustainability program for a national retailer. Derek has testified to the US Senate Energy Committee and briefed the US Secretary of Energy.
