Improvement of embodied environmental impacts and costs of apartments considering the replacement of concrete with drywalls in different indoor designs

초록

As part of an extensive program to provide guidelines on construction materials for architects and engineers to design efficient buildings, the present study analyses the reduction of embodied environmental impact in Korean apartment buildings that use drywall in lieu of other construction materials. Based on the standards for energy-saving eco-friendly house construction developed by the Ministry of Land, Infrastructure and Transport of South Korea, five different floor design plans are used as reference to calculate the energy savings of new apartment buildings and to determine the influence of the type of walls in each room. Based on the reference apartment buildings, evaluated apartment building models were developed by replacing the non-load-bearing walls within the apartment units with drywall systems. Korean national life cycle inventory databases and the Korean Life Cycle Impact Assessment Index (KOLID) framework were applied for environmental impact and cost calculation. As a result, the use of drywall resulted in a reduction of the embodied environmental impacts ranging from 13.58% to 85.74%.
