This paper presents a study on effect of vertical greenery system (VGS) on temperature, humidity and wind speed at
the corridor of a high building and its surrounding. Experiment was performed using HOBO U12-011 devices to
obtain data of temperature, relative humidity and air velocity. It aims to investigate the contribution of thermal
behaviour of the plant for the building corridor. The outcome of the experimental results showed that ventilation
improves the thermal performance of shading climbing plants to reduce the temperature at day and night. It confirms
that the higher air velocity increased heat reduction during the day. The study found that the VGS creates a climate in
an intermediate space which is characterized by lower temperature and higher humidity. The use of VGS can
significantly contribute to energy reduction.
