The garden was structured vertically at 60 degrees slope by using loose system which enabled all vegetables to be directly illuminated by the sun. Measurement of thermal comfort of the building was carried out by opening all openings doors and windows in a dormitory in Rungkut Menanggal Harapan Surabaya. Objective research involved dry air temperature relative humidity wind speed and sun radiation before and after garden installation while subjective research involved questions about thermal environment perception. The research result revealed that during dry season air temperature in the rooms decreased 0 8 C while CO2 level went down ppm and O2 level went up . Thermal comfort or neutral temperature after the hydroponics installation was above ASHRAE standard comfort zone which is 55. Subjectively it was revealed that the tenants experienced higher thermal comfort compared to PMV Predicted Mean Votes prediction. Key words hydroponics vegetables
