The field measurement is conducted on two buildings with the same orientation and at the same time of the day
to ensure they received the same amount of solar heat. The research location was held in Jakarta, Indonesia. To
obtain both temperature and humidity data, two buildings that are located at the same location were chosen. A
company specializing in vertical gardens, PT. Indonesia Greenwall will be the location where the humidity and
temperature data with the presence of vertical garden is taken while the building without the presence of green
facade is represented by the CIMB building located besides the PT. Indonesia Greenwall building (see Fig. 3.).
