State of the Market: Demystifying Dehumidification In Indoor Horticultural Environments
Controlled environment agriculture operations require climate control systems to maintain conditions optimal for plant growth and development. Managing moisture in cultivation environments is crucial for plant transpiration, and removing moisture from grow rooms can be accomplished using various types of dehumidification equipment, each with its own effectiveness and energy impacts.
Plant transpiration is not well understood by efficiency programs and incentives for high-performance dehumidification approaches are often being calculated using custom assessments of energy savings. Cultivators also struggle to understand how different dehumidification systems affect their ability to provide consistent conditions in their growing environments.
Utilities and energy efficiency programs can benefit from understanding traditional and efficient approaches to dehumidification processes and quantifying the energy benefits using consistent approaches that can be standardized to support a greater number of customers and claim more defensible savings.
