การออกแบบอุปกรณ์ยึดพืชอากาศ Tillandsia (cotton candy) เพื่อเป็นหลังคาสีเขียว

Abstract

Thailand is located in the tropical zone with longer summers than the rainy season. The roof is therefore an important part of a building receiving the most heat from the sun in the daytime. Normally the tiled roofs absorb the heat and transfer to the building. Green roofs can reduce heat from the sun by the shading from leaves. It protects the tile from heat leading to the thermal comfort of in the building and saving energy. The objective of this study was to design the air plant holding equipment for Tillandsia (cotton candy) as green roof. The holding equipment must be weather resistant, normal plant growing, and the low cost. The selection of materials is based on the properties which must have no effect to the growth of plants and environment friendly. In experiment, the mock-up of 1x1 m2 have been built with slope of 30 degrees. It is used for the installation of air plant holding equipment i.e. plastic cladding aluminum rod, modified plastic bottle, and aluminum rod. The experiment of air plant holding equipment was done with plants for 12 months (from May 2015 to April 2016) covering both summer and rainy season. The results showed that the total leaf area of the plant panel was increased from 69 to 81%, indicating that the three selected species did not have problem in growth. The plants had fallen around 2-10 points from the equipment mostly in the rainy season because of the wind. The redesigned from aluminum rod by adding rod is a must in order to hold the plant tight to be suitable for the production of prototype equipment for green roofs.
