Modeling green roofs in tropical housing to support micro-scale food security

Abstract

Research on green roofs in tropical residential buildings has the opportunity to be a substitute for productive green spaces. This research implements several vegetable plants as building roof covering elements, i.e., peanut, eggplant, chili, and tomato. Experimental research was applied jointly for six months on four types of vegetables on a green roof covering an area of sixteen square meters. The green roof model consists of a green roof model on concrete and corrugated zinc through a floating technique as a roof model engineering. The aim of this research is to examine the roof as a substitute for green space in buildings. The results showed that the four types of vegetables could grow well on both roof models, both types of green roof have the opportunity to be implemented in residential areas, resulting in fruit that could be consumed on a household micro scale.
