Amidst climate change, diminishing resources, and a growing population, the farming industry has come under significant pressure. Nonetheless, rapid advancements in modern agricultural technologies offer substantial potential to enhance production efficiency. The proposed smart greenhouse (SGH) provides a controlled environment for the crops within it. Equipped with sensors and communication technologies, a smart greenhouse automatically measures and delivers information around the clock, activating the greenhouse’s heating, ventilation, and air conditioning (HVAC) systems. The pilot SGH developed in Genekha, Thimphu, has integrated sensors and renewable energy technology as an energy source to supplement during the cold winter season. No external heating sources are required during the summer period. The SGH was initially simulated using TRNSYS and OpenStudio simulation software. Performance parameters such as temperature and humidity inside and outside the SGH were collected and analyzed. Additionally, parameters like soil pH and nutrient content were measured. The time required for crops to grow and be harvested was recorded and is presented in this paper. The paper also concludes by highlighting some of the limitations of the current design and providing recommendations for future improvements.
