GREENHOUSES ELONGATE THE PRODUCTION SEASON BY CREATING OPTIMAL GROWTH CONDITIONS WITHIN THE HOUSE AND IMPROVE WATER EFFICIENCY TO REDUCE IRRIGATION WATER WITHDRAWAL BY ~ 70 % COMPARED TO OPEN-FIELD AGRICULTURE.THE WATER AND UTILITY ENERGY (ELECTRICITY AND NATURAL GAS) CONSUMPTION OF GREENHOUSES ARE CLOSELY RELATED TO THE CROP'S PHYSIOLOGICAL RESPONSES, REGION AND GROWING SEASON.WE HAVE ASSEMBLED A TEAM WITH COMPLEMENTARY EXPERTISE IN THERMAL/ENERGY SCIENCES, OPTICS AND MATERIALS, SCALABLE MANUFACTURING, SOLAR-DRIVEN WATER PURIFICATION, GREENHOUSE HORTICULTURE, AND CROP PHYSIOLOGY. IN THE LAST YEAR OF THIS PROJECT, WE ARE FINALIZING OUR ANALYSIS AND MODELS ALLOWING TO ESTIMATE THE IMPACT OF LIGHT SPLITTING FILM ON PLANT GROWTH, THE ADVANTAGES OF INTEGRATED GREENHOUSES THAT CAN TREAT WATER, GROW CROPS, AND USE SOLAR ENERGY TO HEAT AIR AND WATER, THUS HELPING THE ENVIRONMENTAL CONTROL OF THE GREENHOUSE.
