Abstract

The ground source heat pump (GSHP) using radiant heating can reduce energy consumption and ensure thermal comfort for occupants, compared to convective heating method. However, to utilize the GSHP using radiant heating as a technology for achieving zero energy buildings, it is necessary to quantitatively assess the environmental impact. Most previous studies have focused on the energy efficiency aspects of the GSHP using radiant heating, but there is a lack of quantitative data on the carbon emissions generated. Therefore, in this study, to quantitatively assess the environmental impact of the GSHP using radiant heating, an integrated simulation model based on energy simulation was developed. The life cycle assessment method was used to analyze the carbon emissions generated during the manufacturing, installation, operation, and disposal stages. Moreover, to demonstrate the environmental benefits of the GSHP using radiant heating, the carbon emissions were compared to convective heating.
