The purpose of this study were to investigate the state of indoor environmental factors and energy consumption during winter in residential houses and to analyze factors which influenced this environment. Energy consumptions and indoor environmental factors of this survey were conducted in 21 houses(apartment, 11 and detached houses,10) between December, 2010 and February, 2011 which measured energy consumptions and indoor environmental factors as well as kept records of interviews with residents and other related factors. The results obtained were as follows. Indoor environmental factors which were found to influence apartment houses higher than detached houses. The average gas consumption of detached houses(90.98³) was higher than that of apartment houses(76.33³). Gas consumption showed positive correlations to temperature and carbon dioxide in the residential houses. The mean concentration of PM₁₀, and CO₂ in large family were higher than those of small family. We found that the more gas consumption, the higher concentration of PM₁₀, CO₂ and temperature(p<0.01).

CO₂ and PM₁₀ in military barracks were studied using DustMate, Mini Vol. Air Sampler and DirectSense^TM PPC TG-502 Monitoring Kits in 2010. The distributions of CO₂ and PM₁₀ in the military base were strongly affected by soldier's behaviors as well as managements for the barracks. Before this study, the military site may fail to follow "IAQ Administration Law of Multiplex Utilization Facilities, ect." in terms of CO₂ and PM₁₀. After adopting advanced cleaning methods and ventilation system, the concentrations of CO₂ and PM₁₀ were maintained under the regulation, respectively. The distribution of CO₂ was related to the number and time of ventilation. In contrast, PM₁₀ was dependant on the soldiers' indoor-activities rather than ventilation. This study supported that management and education for barracks and soldiers plays in a role to control indoor quality of military facility.
