판상형 아파트와 탑상형 아파트의 도시가스 소비 특성에 관한 비교 연구

Comparative Study on the City Gas Consumption Characteristics of Flat-type Apartment and Tower-type Apartment

This study was conducted for the private apartments that use individual heating using city gas among the high-rise apartments in Busan, Gyeongnam region. The research subject apartments are 2,345 households in 11 complexes of plate-type apartment constructed in the 1990s with about 85㎡ of net floor area and 599 households in 3 complexes of tower-type apartment constructed in the mid 2000s in the total of 2,944 households in 14 apartment complexes. The city gas usage amounts during the 12 months in 2008 from these two types of apartments were extracted to examine the actual condition by comparatively analyzing the differences in the gas usage amount, the gas usage amount according to floor and the city gas usage amount only for pure heating purpose. Through such city gas consumption amount comparison, this study sought to examine the effects of insulation performance improvement of apartments thus far and provide basic information for efficient energy control and insulation design plan for apartments. As the result, it was revealed that the tower-type apartment uses 13.2% less gas than the plate-type apartment. Also in the pure heating purpose gas usage amount, it was used 27.3% less in the tower-type apartment. Also, the research revealed that the difference between the lowest floor and the highest floor in comparison to the middle floor was much more significant in the plate-type apartment. Through such results, it was found that increasing the insulation of apartment by strengthening the insulation law, along with the improvement of materials and construction methods, brought much results in the reduction of heating energy
