1 Purpose and Scope
1.1 This Engineering Practice sets forth guidelines describing the plant shoot zone environment and the interactions with plants grown indoors without sunlight.
1.2 This Engineering Practice establishes criteria that will promote the cultivation of plants, with a focus on the thermodynamics and air quality of the indoor plant environment.
1.3 The intended audience of this Engineering Practice is the owner and operator of the indoor plant environment (i.e.: “the grower”).
1.4 This Engineering Practice presents design considerations associated with selecting HVAC equipment currently available and commonly used to manage the temperature, humidity, and air quality in the indoor plant environment.
1.5 Excluded from this Engineering Practice are: HVAC systems serving water-cooled LED lighting; HVAC condensate drainage capture, treatment and reuse; thermal storage; and phase change building materials.(Download PDF) (Export to EndNotes)
