Performance evaluation of moss rooftop greening prototype in a confined space

This research presents performance evaluation of moss rooftop greening prototype in a confined space using an experimental chamber. The chamber was utilized to simulate performance of prototype in reducing temperature inside a building. Two simulated environments were set as low and high-temperature treatment. Moss plant (Sphagnum sp.) was used. Performance was evaluated by using Lab color, photosynthesis and CO2 absorption rate. The results concluded that prototype could reduce temperature inside confined space from 1.5 to 2.9 °C. L and b parameters were applicable to detect the color patterns. The high-temperature had no effect on while low-temperature treatment decreased photosynthetic and CO2 absorption rate. These results concluded that the prototype could be applied as a rooftop greening material in tropical environment of Yogyakarta, Indonesia.
