Greenhouses for Saudi Arabia
Cooling is the project here. Evaporative works inland where the air is dry; coastal sites need mechanical dehumidification or a hybrid.
Site conditions to design against
| Summer | 45–48 °C peak, high radiation |
| Winter | 5–15 °C in the interior |
| Humidity | very low inland, 60–85 % on the coast |
| Light | very high year-round |
| Wind | dust and shamal events |
| Water | scarce; desalinated or treated water common |
Regional ranges for early planning. Final loads and set points come from your own site data, or from a design value we propose for review.
What that changes in the design
| Cooling | Evaporative cooling is viable in dry air; in humid air it adds moisture and mechanical dehumidification takes over. |
| Water | Closed substrate systems with drain recovery carry both the agronomy and the business case. |
| Winter design | Heating, insulation and snow loads are a second design case. Phasing a spring-to-autumn house first keeps capital off the critical path. |
| Wind load | Wind exposure sets the frame, the vent drives and the roof detailing; vent control needs a wind override. |
Market context
Protected vegetable area reached about 6,096 ha in 2023, and the ministry approved an expansion programme with roughly SAR 4 billion of expected investment aimed at more than one million tonnes a year. Ministry studies put water savings from modern greenhouse technology at up to 60 % against field irrigation.
