This research describes the effects of injecting rigid polyurethane foam into walls and fitting doubleglazing or inner panes to sash windows as simple renovation methods for houses, based onestimations of CO2 emissions from heating/cooling and LCCO2 (Life Cycle CO2). We estimated CO2emissions and LCCO2 up to 2020 in Japan and obtained the following results.(1) Injecting rigid polyurethane foam into walls in detached houses, where there is little thermalinsulation, reduces the LCCO2 significantly.
