Future-proof your commercial cultivation operation by understanding the best practices for designing, installing, and operating HVAC and dehumidification systems to manage moisture, temperature and air circulation. This seminar is designed to provide craft cultivators in Northern California climates, and their design and construction project partners, with what they need to know to stay competitive and comply with regulations. Experts in resource efficient production will present on high performance HVAC and dehumidification equipment to maintain the environmental conditions needed for optimal plant growth and development, upcoming code changes, utility incentive programs, and strategies to increase productivity in plant production operations. The audience will participate in a discussion where attendees can get answers to questions about growing and saving money with energy-efficient HVAC and dehumidification equipment.

Topical areas include:

  • Importance of HVAC design in craft operations

  • Typical HVAC system choices for craft growers in greenhouse and indoor cultivations

  • Selecting efficient target environmental conditions

  • Estimating HVAC loads and sizing HVAC equipment for greenhouses and indoor

  • Common HVAC mistakes in craft cultivations

  • Commissioning and maintenance considerations for craft cultivators

  • Working with your utility and maximizing incentives
