Abstract
This study investigates the effectiveness of
night sky radiation cooling for greenhouse roofs in the Arabian Gulf region,
where extreme temperatures (often exceeding 45°C) challenge conventional
cooling methods. Five roof configurations (flat, sloped, gable, vaulted, and
pyramidal) were evaluated using experimental measurements and computational
modelling. High-emissivity materials including glass, polyethylene film,
fiberglass, and polycarbonate sheets were tested for their radiative cooling
potential. Results demonstrate that flat and vaulted roofs with polycarbonate
coatings achieved the highest cooling performance, reducing nighttime
temperatures by 5-7°C compared to ambient. These configurations reduced energy
consumption for active cooling by 20-30%, offering significant potential for
sustainable agriculture in arid climates. The findings provide practical
guidelines for greenhouse design optimization in regions with similar climatic
conditions.
