STUDY ON OPERATIONAL CARBON REDUCTION EFFECTS OF WINDOWS WITH VARIOUS THERMAL PERFORMANCES INSTALLED IN NON-RESIDENTIAL BUILDINGS

Abstract

This paper reports the results of a study aimed at quantitatively understanding the impact of thermal performance of window on the operational carbon of non-residential buildings. Model buildings were set up for each building use, and the CO₂ emission reductions per unit window area are calculated for a total of 19 different window specifications, assuming average building design specifications for new construction and renovation. From the calculation results, the relationship between window thermal transmittance and CO₂ emission reduction is shown, and the characteristics are clarified for each building use and region.
