An Evaluation Building Passive Cooling Achieved Through Modification of Herbal Garden Configuration

Abstract

This paper focuses on the passive cooling effect of herbal garden application in increasing thermal environment of modern house in hot humid climate. The study focused on horizontal gardern gap and vegetable plant type modification. The methodology was developed and applied using field measurement on indoor and outdoor. In increasing thermal environment, its impact, higher levels of horizontal garden gap (distance from house facade) produced the indoor air temperature reduction. Further, several modifications were found to produce a potential building cooling load reduction of up to 5°C by the use iresine herbstii hook (bayam merah). In fact, the optimum improvement of both outdoor and indoor environment was influenced by two major horizontal garden factors, namely, larger horizontal garden gap and type of herbal plant. Thus, it is suggested that appropriate guidelines, influencing implementation of these improvements could be implemented in order to increase thermal environment in hot humid climate.
