HYDROPONIC GARDEN TO IMPROVE THE THERMAL COMFORT OF THE ROOM: A CASE STUDY INDONESIAN

Abstract

- This study examines the level of thermal comfort in the student dormitory room after being given a
vertical hydroponic vegetable garden on the part of the building facing the West (sun). Vertical arrangement
of the garden with a slope of 60 degrees uses a loose system so that all plants are directly exposed to the sun.
Measurement of thermal comfort in buildings with all openings (doors and windows) open, applied to student
dormitory at Rungkut Menanggal Harapan Surabaya. Research is objectively related to dry air temperature,
relative humidity, wind speed and solar radiation in the initial conditions and after the park, whereas research
subjectively involves questions about the perception of the thermal environment. The results showed that in
the dry season the indoor air temperature decreased by 0,8 ?C, while the decrease in CO2 levels by 2,56 ppm
and an increase in O2 levels by 0,6 %. Thermal comfort or neutral temperature after hydroponic garden is
above the comfort zone of ASHRAE standard 55. Subjectively it reveals that users feel a higher level of
thermal comfort compared to the prediction of PMV (Predicted Mean Votes)
