In regard of energy, Korea is poor country, which imports 97% of its energy from foreign countries. And energy saving problem is the national task because our country is recently suffering from the rise of oil price badly. In terms of this, it is important to take measures for energy saving in the buildings, which spend about 25% of national energy. Therefore, in this treatise, change of insulation standard in apartment and its effect are studied to provide basic data in taking measures for energy saving in the apartments, which use energy most among all buildings. The quantity of city gas consumed at 2,747 households of seven apartments complex in Gimhae was compared and analyzed for the study. The data source was provided through companies supplying city gas. As a result, it is found that in regard of insulation standard of Korea, the function of insulation has been improved through various revision so far, but the insulation standard about fittings(windows and doors) has been eased on the contrary. It is found that complement of insulation standard about fittings(windows and doors) is needed surely, because it is found that the apartments, built in 1990s, spent the city gas as much as the apartments, built after 2002, caused by above fact.
