Abstract
Much energy is consumed by household sector, especially in heating and cooling. CO2 emission constitutes about 27% from household consumption per person. The construction related sectors such as cement, transportation, Cray and stone havealso very high intensities of energy consumption and CO2 emission. Therefore, for the preservation of the environment, it is important to reduce housing and construction activities related energy consumption has significant reduction effects on energy consumption and CO2 emission. The construction energy saving housing induces CO2 emission of 102kg per annum, but it reduces CO2 emission by 689kg. Thus, CO2 reduction amounts to 587kg per house. If energy saving construction is applied to all residential and commercial buildings, about 4% of the total CO2 emission can be reduced.
