Abstract
The global building construction activities is responsible for 30-40% of global energy consumption thus with this contributes around 30% of greenhouse gas emissions. The holistic approach by green buildings recon can reduce 30-50% of energy usage, 35% of CO2 emissions, 70% of waste generation and 40% of water usage. However, the decline in financial markets and economic turmoil has meltdown interest of investors towards green-certified buildings due to higher cost implications and needed bigger capital. Additionally, Green Building Rating Tools (GBRT) do not provide Life Cycle Cost (LCC) analysis, where at the same time is a lack of available decision making support tool for GBRT integrated with LCC. This research developed an integrated web-based system which has applied GBRT, computer programming, and LCC analysis. This study has used Malaysia Carbon Reduction and Environment Sustainability Tool (MyCREST) for the integration with LCC. The study identified criteria, sub-criteria and super sub-criteria of MyCREST and with elements of LCC that combine to develop an integrated framework, thus later was transformed into an automated analogue computerised programming system using architectural programming flow system. Twenty-five sets of matrix form of MyCREST and LLC have been developed for the confirmation of professional in the field of GBRT and LCC. Two levels of Focus Group Discussions (FGD) were conducted amongst Qualified Professionals QP?s of GBRT. The quantitative data were analysed using (SPSS V.17) software that achieved frequency analysis, factor score analysis, weightage factor analysis and developed the cost control weightage distribution. The results output led to the development of cumulative control weightage of LCC. The cumulative cost control weightage indicates management cost 35%; development cost 20%; operation cost 14%; construction & installation cost 11%; maintenance cost 10%; replacement cost 6%; and contingencies cost 4%. The achieved cumulative control weightage is later were formulated into automated analogue computerised programming whereby this web-based innovation is named MyCREST-LCC. This MyCREST-LCC tool provides easy, efficient and effectively integrated programming that also offers to forecast of lifetime cost occurrence in green buildings. In conclusion, this innovative new approach of integrated automated web-based MyCREST-LCC assists construction stakeholders in the construction industry for providing a better, easy and quick way of decision making. The outcome adds value to green building project development, thus mapping the future cost that incurs in any proposal of green building development either locally or international wide.
