Abstract: The objective of this work is to develop a low cost composite natural fiber material for the application of improving the energy efficiency of building and also to improve the building cooling effect. This work involves investigation of the thermal properties of Natural fiber composite which is used to reduce heat transfer into the building. The selected three fibers namely (Sisal, Jute, Flax) are mixed with some certain ratio epoxy resin and hardener to prepare the composite panels. Composite materials have ability to absorb and store heat before releasing it. The thermal insulation composite panels (natural fiber) were produced and the composite material for the roof and wall which were experimentally determined the energy performance of the building application. An experimental investigation of the natural fiber composite panels were performed using heat flow meter to measure the thermal conductivity of composite materials.
