Abstrak :

Disasters attack Indonesia frequently, causes increase of poverty. Nobody can predict, prepare or avoid when a disaster happens, neither the rich nor the poor. The rich may become poor at once even less may the poor. Within a year the population of poor families in Surabaya, for instance, soared 140,000 families. In 2006 the population was 357,268 families. In 2007 the total increased to more than 500,000, the increase is 40%. This data was the result recently verified by BAPPEMAS (Board of Community Empowerment) of Surabaya on 163 sub districts. This data will be related to facilities contributed to them. Besides, as prices of world gas sky high, prices of everything follow to go up and depress the economic situation especially low income community. This situation influences the poor community capability in purchasing houses. Due to reaching affordability, efforts were done by governmental, non-governmental and private institution. Among such efforts are: KREMADA, cooperation between Directorate General of Public Housing and Department of Pawn-Service on credits for housing renovation with interest rate only 8% a year; SELF-HELP housing in Batam hinterland, cooperation with Batam municipality on self-help housing program; NEW NGELEPEN VILLAGE, contribution of WANGO (World Association of NGO) on 80 Dome housing units and public facilities for relocation of Jogya earthquake victims.

The latest mentioned is the discussion that we would like to analyse here. Dome shape is actually concluded as strong and stable construction. For low cost houses, beside affordability, those requirements are indeed very important, but other requirements especially those influencing comfort living within house during whole day and night is apparently important too.

According to sustainability principles, sustainable housing design should be considered under several points of view wisely such as: economically, socially, environmentally, and architecturally. In more detail, the discussion will concern especially with its climatic design. In this case, Ngelepen dome house will be described for its plus as well as its minus value.
