Performance and life cycle cost analysis (LCCA) for heat resistant wall

The main aim of this study to seek a passive cooling method that can minimize the use of air conditioning system while saving energy consumption. There have three objective in this study. The first objectives is to find out the optimum way in enhancement of green building technology with getting opinions and suggestions from the Green Building Index professional staff. Enforcement and full support by the Malaysian Government identified to give a significant role in achieving the first objective. The second objective is to develop and evaluate an affordable heat resistant wall panel system to improve energy efficiency. Different types of wall panel concept and design were constructed and tested to compare the best performance in thermal resistance. In this study, the Heat Resistant Wall Panel with flowing water shows the best performance in reducing the building’s indoor temperature during the simulation. A significant temperature drop was found in this wall panel type: reached 6C at the extreme temperature (35C). In order to determine the energy efficiency and cost saving, the Life Cycle Cost Analysis (LCCA) was performed as to complete the third objective. As a result, the Heat Resistant Wall Panel with flowing water inside was discovered as the most suitable solution in reducing indoor temperature and as a way to save energy with the payback value occurred at 9th years later. Furthermore, about 30.6% cost reduced by using the Heat Resistant Wall Panel with flowing water in term of annual maintenance and services cost.
