In low cost housing of warm humid regions where natural ventilation is usually employed, the presence of
large openings will also cause unnecessary glare and heat gain of solar radiation This paper reports a preliminary
study to handle glare issue without impairing natural ventilation. The use of climbing vegetation planted on a
frame with fully adjusted foliage dense as shading devices is investigated. The frame is placed at the most
possible position of the low cost housing and two variables, i.e. foliage porosity and leaf surface reflectance is
studied using two computational simulation methods. Radiance is employed to calculate glare index after the
vegetative shading and Brevent is used to assess ventilation flow rates occurred indoors toward indoors thermal
comfort of the modelled housing. The study indicates that using climbing vegetation is possible for both
reducing glare and supplying the required ventilation flow rates at the same time.
