Precision horticultural climate engineering parameters, solar Daily Light Integral (DLI) curves, seasonal thermal screen deployment strategy, and heating/cooling load calculations for Westland, Netherlands (Maritime Temperate (Cfb)).
In Westland, Netherlands, natural solar Daily Light Integral transitions from 6-10 mol/m²/day during winter solstice to 35-42 mol/m²/day at summer peak. For commercial crops like High-Wire Tomato, Sweet Pepper, Cut Flowers, target canopy DLI requires dynamic screen management to avoid photoinhibition during midday radiation spikes exceeding 850 W/m².
Screen Specification: Double Screen (Energy 47% + High-Grade Diffuse 20%)
Primary Cooling Strategy: Roof Natural Ventilation + Screening
Maintaining positive day-night temperature differential (DIF) and nighttime dehumidification minimizes condensation on cold structural glass surfaces, suppressing Botrytis and powdery mildew spore viability.
Major protected cropping varieties grown at scale in this regional cluster: High-Wire Tomato, Sweet Pepper, Cut Flowers.
