STUDY ON OPERATIONAL CARBON REDUCTION EFFECTS OF WINDOWS WITH VARIOUS THERMAL PERFORMANCES INSTALLED IN DETACHED AND APARTMENT HOUSES

Abstract

CO₂ emissions for heating and cooling were calculated for standard models of detached houses and apartment houses. Based on the results of heating/cooling CO₂ emissions for various window performances, some examples of CO₂ emission increase/decrease per unit window area for the study window compared to the standard window was shown. In the future, it will be possible to study CO₂ emissions over the entire life cycle of a house for each window performance by combining the embodied carbon and the CO₂ emission increase/decrease during use as shown in this study. This is expected to lead to reduction of CO₂ emissions.
