As of 2018, the proportion of permanent rental and national rental for low-income households accounted for 53% of the total rental housing inventory. Residents of small rental apartments can be categorized as energy poverty, mostly as elderly or handicapped people. They are lived in a low indoor temperature and high condensation possibility. However, there is no study on the indoor thermal environment of permanent rental apartment for low-income households. Especially, indoor temperature distribution and moisture generation and resulted condensation behaviors of aged permanent rental apartment is reported. The aims of this study is to investigate the actual condition of the condensation problem in old apartment buildings for low-income households by long-term measurement. The room temperature and humidity were measured by long-term measurements for the 17 households(7 households are newly constructed and 10 households are old building). Also, the airtightness and window insulation performance were measured. Finally, the generation of water vapor and the occurrence of condensation were analysed based on the measurement results.
As a result, the level of water vapor generation for the aged permanent rental apartment showed a large variation according to the lifestyle of each household. Mostly the analyzed households showed significantly lower humidity level compared to the conventional level defined by the IEA Annex. The moisture generation rates of the analyzed low-income households were divided into three levels: 5.05kg/day(max.), 1.88kg/day(mean), 0.32kg/day(min.). The condensation occurrence frequency was 0.3~79% and showed a large deviation. The households with high condensation rates were old building.
