EXPERIMENTS TO RENOVATE THERMAL INSULATION AND ESTIMATION OF LCCO_2 WITH INJECTING POLY-URETHANE FOAM INTO MODEL WALLS FOR HOUSES(Environmental Engineering)

Abstract

The number of domestic existing houses has been increasing; over 46 million in 2003. However, all those insulation levels are not high enough. Therefore in the household section, the renovation of thermal insulation is expected for the effective reduction of greenhouse gas. This research describes new renovation method for thermal insulation through the experiments with injecting poly-urethane foam into model walls. Further more, according to the results of those experiments, we clarify the effect on LCCO_2 reduction.
