An embedded joint management body (JMB) in a comprehensive life cycle cost analysis planning mode in sustainable building project

Abstract

Sustainable building is devised to diminish the environmental impacts of the project life cycle. Sustainability feature selections and waste reductions are essential to the designer during the inception stage. Consequently, the operation cost imposed by the JMB has been raised. This study aims to analyze the cost of involving JMB in the design stage to overcome this design gap. This study analyzes the influence of research and development criteria and their cost association in the initial stage of the project and excludes future costs. The aim of this research is to overcome the issues raised during the operation and maintenance phase of green building, which led to overestimating the operating budget. The implemented methodology in this research comprises secondary and primary data collection. The prime data was collected using a questionnaire survey distributed amongst qualified experts and professionals within green buildings and facility management. The data were analyzed using factor analysis to determine the factor score and weightage factor of the relevant JMB and Life cycle cost analysis. It is found that the highest weightage criteria are innovation, with a total weightage factor of 36.7 %, and criteria engagement of people has 19.2 % as the lowest. The study also explored additional perspectives by verdict association of cost element of JMB involvement and found that management cost is highly associated with research and development criteria with the value of 19 %, followed by development cost with 17.5 %. The outcome of this research will add value to green building development and uplift facility management and sustainable development with a low cost of operation and fees imposed. Furthermore, it paves the way to integrate various criteria of engaging JMB in design and its costs associated with the initial and future phases.
