The purpose of this study is to determine factors affecting QOL among residents in major cities of Indonesia. A survey (n=236) was carried out in the city of Bandung from September to November 2012 for the above purpose, focusing especially on unplanned houses in Kampung. The results showed that approximately 60.1% of the respondents gave positive answers to their QOL on average. The result of structural equation modeling (SEM) showed that ‘happiness’ including life satisfaction and QOL can be explained by the levels of ‘attachment for house and neighborhood’, ‘living environment’, ‘satisfaction for residence’ and ‘human relationship’, in particular. Further results implied that improvements of ‘human relationship’, ‘religion’, ‘cooperation in community’ and ‘living environment’ are the keys to achieve energy-saving objectives in these houses without disturbing the improvement of their QOL.
