Thermal Performance of Plastered Bamboo-Wall
Abstract
This paper reviews the application of plastered-bamboo wall (PBW) as an alternative wall construction to replace a conventional brick wall, that are evaluated based on thermal aspects. Brick as the material which is composed of a wall has a high value of density. High-density materials generally have a great heat capacity and contribute to raising the ambient air temperature. On a large scale, they can trigger the occurrence of a heat island phenomenon (UHI). PBW is a technique of wall construction, which are composed of bamboo as a frame and mortar as a frame cover. The thickness of the PBW ranges from 5 to 9 cm. PBW has a lower value of density than a brick wall. This study aims to test the thermal performance of PBW based on its constituent framework, which is divided into two groups of specimens, namely; bamboo woven, and bamboo array. The samples were tested in the field and arranged in such a way as to be exposed to solar radiation. In practice, the heat capacity of specimens was identified through its density. Meanwhile, the thermal performance of samples was identified through time lag (TL) by using thermocouple and globe thermometer. All the results indicate that specimens with bamboo array have better time lag value (longer time) than all specimens with bamboo woven.
