This paper investigates the effectiveness of using fiber cement weatherboard as a sustainable building material in Traditional Chalets at the Belum Rainforest Resort in Perak, Malaysia to conserve nature. The paper studies how the selection of materials at the design stage can impact the long-term sustainability of a building and its effects on nature. It reviews literature on fiber cement weatherboard and identifies it as a green material that is attractive, low maintenance, and can provide benefits over other materials like PVC or wood by being rot resistant and easy to install while maintaining a natural appearance. The conclusion is that fiber cement weatherboard is a sustainable material that can effectively conserve nature by promoting built environments without negative impacts on the natural environment.
