Cost Comparative Analysis of a New Green Building Code for Residential Project Development

AbstractThis paper presents a comprehensive cost comparative analysis for the impact of the new Green Building Code on residential project development from project management perspectives. As the demand for new residential housing is gradually increasing from the long recession, residential project management is vital for project owners making decisions concerning the investment of new green building features, such as energy-efficient appliances, equipment, and lighting. The analysis results show that the incorporation of such green systems causes the construction costs to increase by 10.77% more than the traditional building, whereas the amount of working days only increases by two days. The findings can be used as a guide for project owners to make decisions concerning their monetary initial investments while benefiting from energy cost savings over the life cycle of the building.
