Abstract

This paper presents the use of bioclimatic design using the vertical greenery system (VGS) for a building. The design refers to the temperature and humidity conditions that make humans comfortable and minimize energy consumption particularly in reducing the urban heat island effect. Using vertical plant in front of the building envelope decreases the surrounding temperature. It shows that lower wind speed and higher humidity on the microclimatic layer are characteristics of a VGS that reduces energy consumption for cooling and heating of buildings. This means that the VGS acts as a wind barrier and verifies the effect of evapotranspiration from plants. In this study, the focus is on living walls and green facades placed independently in front of the inner layer of a building corridor. It aims to regulate the temperature and relative humidity, thus creating a thermal comfort environment. Two vertical greenery systems consisting of a modular living wall and green cable facade were installed at the east-corridor wall along the 3rd floor of a 5-storey building wall in Petaling Jaya, Malaysia. Two series of experiments were carried out for temperature and humidity using a Hobo U12-006. The results showed that the cooling effect of a modular system is higher than a cable system. It implies that the modular design and lush vegetation influence the effectiveness of the VGS.
