Natural symptoms due to climate change have begun to be felt in Bandar Lampung city over the last few years. One of the reasons for this situation is high energy consumption to obtain thermal comfort in buildings. Efforts to slow the rate of climate change need to be made by reducing building energy consumption. In this study, an experiment was carried out in the form of applying VGS (Vertical Greenery System) to building facades as a strategy to reduce building energy consumption. The purpose of this research is to understand how to reduce the cooling load on a classroom on a campus building in the tropics by applying VGS based on green architecture principles. The research was carried out using a software-based modelling method. After the VGS model is implemented, the EUI value required to meet the existing sample room comfort standards is 1067 MJ/m2/year or the equivalent of 11,206 kWh, if converted into cooling load units (BTU) it is as much as 38,236,459 BTU. The costs required to meet energy needs are $726 or the equivalent of IDR 11,237,463.60 (exchange rate 15,478.60). The application of VGS in the room has an effective value of 10.2%. © Published under licence by IOP Publishing Ltd.
