IMPLEMENTING VERTICAL GREENERY ON OFFICE FAÇADE OPENING TO IMPROVE INDOOR LIGHT QUALITY

In medium-rise office buildings in tropical climates, façade fenestration is mostly dominated by a glass curtain wall. In this case, an effort should be done to control the daylight penetration and to shade glare of low sun angle, especially from a west orientation. The idea is to utilize the vertical greenery system (VGS) on facade opening, how it performs as glare limitation as well as accommodating view. Firstly, the variable of artificial shading to a light parameter is studied. Then, the previous research on VGS was explored, to find its influential variables. The last step was to develop a recommendation for VGS implementation on office facade opening to improve light quality. Finding from the study, the most influential variables are the plant species suitable to the climate condition, its canopy leave area as a light variable, and the placement; integration of the plants’ construction system with other facade elements which consider light angles of incidence and viewer’s sightlines.
