This study investigated the economic comparison between bamboo reinforced concrete called Bamboocrete with the conventional reinforced concrete panel. Materials contribute significantly to the construction cost. Bamboo can be an alternative to replace steel bars in typical reinforced concrete as it is low in cost and sustainable material. To optimize the benefit, this study used whole solid bamboo as the reinforcement as well as to reduce amount of concrete in the panel, thus reducing the panel weight. Furthermore, the concrete used is lightweight concrete by partially replaced coarse aggregate with Palm Kernel Shell (PKS). The Bamboocrete panel at 1 500 mm height, 300 mm width, and 125 mm thick can sustain axial load of more than 100 KN (10 ton), and flexural bending load between 32.51 to 35.20 kN. Bamboocrete panel contribute towards economical building structures when it is 14% cheaper than steel reinforced concrete. Furthermore, bamboocrete panel is 23% lighter.

Population growth and industrial demand are related in construction of buildings and houses which contribute to increment of energy consumption. The invention of phase change materials (PCMs) with high latent heat capacity were explored to be integrated into building materials. PCMs are substances that are capable of storing large amounts of thermal energy as latent heat during their phase transition. Development of this product can ensure a comfortable indoor temperature in buildings without depending on air conditioning system which consumes more energy and damage the environment not to mention contributing towards global climate change. This research concentrated on proposing the method of PCM incorporation and its heat resistance performance. Calcium Chloride Hexahydrate (CaCl₂.6H₂O) was used in this research while the incorporation method is direct mixing into gloss paint and added into zip-lock plastic then covered by conventional cement plaster. From the data obtained, we can see the PCM incorporated wall is better in heat resistance than wall without PCM resulting difference in temperature between internal and external wall 3 ˚C rather than 1 ˚C. For the conclusion , PCM incorporated wall can decrease the internal temperature of building slightly contributing to conserving nature by reducing air conditioner system consumption.
