Evaluation Model for Carbon Dioxide Emissions of Construction Methods

Greenhouse gases and higher energy consumption due to industrial activities have led to serious problems such as global warming. To solve this problem, various acts are adapted and many researchers have conducted studies to propose improvements. Furthermore, the construction industry has embarked on many studies to achieve sustainability of various resources required for construction projects. Most Life Cycle Assessment models developed in previous researches for use in evaluating an environmental performance, however, were developed for a manufacture and maintenance phase of construction projects. Therefore, it is difficult to evaluate the environmental performance in a construction phase. Generally, the environmental performance in the construction phase depends on construction methods used. Therefore, in this research, to evaluate the environmental impact of the construction phase, the construction methods based on the construction process of residential buildings were reviewed. Moreover, an evaluation model for the carbon dioxide emission of the construction methods was developed based on the LCA methodology. Through the developed model, eco-friendly construction methods that can enable carbon dioxide emission reduction are expected to be selected.
