Crop production and quality in controlled environment agriculture (CEA) greenhouses is dependent on the performance of the HVAC systems to maintain target environmental conditions. Growing crops in greenhouses involves using HVAC equipment to minimize pest, disease, mold, and fungus issues and maximize consistent yields. The crops you grow - food, floriculture, or cannabis - and your greenhouse location and construction influence your environmental control strategies. Understand the process application for your HVAC systems to choose efficient lighting products, reduce energy use and operating costs for resilient greenhouses, and maximize incentives from your local utilities and efficiency programs.

Rob Hanifin is a climate consultant with Ludvig Svensson’s American subsidiary. He focuses on technical support to greenhouse growers in using their curtains to help optimize their greenhouse climate. He also provides service and guidance to growers as part of Svensson’s Climate House offerings. Rob joined Svensson in January 2017, when he was based in Oregon. He moved to Michigan in 2019, and is now better positioned to support growers throughout the Midwest US and Ontario, as well as provide support for Svensson’s sales team. Overall, Rob has over ten years experience in CEA.
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.
