Evaluasi Termal Vertical Greenery System Tipe Green Facade pada Dinding Bangunan

Increasing of ambient temperature due to global warming has a direct impact on increasing the room temperature. Heat from surrounding is transferred to building wall and room. By installing the Vertical Greenery System (VGS) on the building wall, it can be an alternative for heat absorber and eco-friendly indicator. The aims of this study are to determine the temperature that can be reduced by VGS type Green Façade (GF) and achieve the energy consumption reduction because of GF installation. GF is installed on the building wall, property of Mining Engineering Department, Sriwijaya University, to measure its temperature, then compare it with the temperature on control wall. The results showed that the GF can reduce the room temperature up to 1,2oC, compared to the control wall and the average is 0,3oC. The decrease in average temperature causes a decrease in energy consumption due to the use of air conditioners by 1.56-1.92%.

The Green Room method: incorporating green façades into whole building energy models

This project proposes a technique, called the Green Room method, to enable incorporating a Green Façade into a whole building energy model using software from Integrated Environmental Solutions, called Virtual Environment (IES-VE). The technique sees a room created onto the exterior walls of a building. This room has geometry similar to that of a planned or actual Green Façade and sees thermal properties assigned to its walls which are also similar to the ones of the vegetative cover growing on the structure of Green Façades. In addition, a mechanical system is assigned to the void space of the green room (plenum) in order to dissipate the thermal gains from solar radiation through evaporative cooling, imitating plant transpiration and other biological functions. Results indicate that the Green Room Method is accurate in predicting the thermal behaviour of Green Façades.
