A Review of Bioclimatic Housing Performance in Kampung Surabaya Using Response Surface Methodology

The existence of old houses as folk's houses in urban villages or kampong in Surabaya City that are still sustainable can be a precedent for today's architecture. Kampung with residential neighborhoods and dense urban village communities with middle to lower socio-economic strata have produced many distinctive architectural styles of houses. Several studies have shown that kampung’s housing has high adaptability to urban developments. A comprehensive review of adaptation, one of which is a bioclimatic adaptation, where the performance of the house building is influenced by the relationship of living organisms, climate, and shape of the building. Bioclimatic adaptation as an architectural strategy is based on comfort-based rationale and low energy to create buildings with better thermal performance. Then how does the thermal performance of old houses as cultural products in the kampung contribute to sustainable thermal comfort? For this reason, the development of a response surface methodology is used as a technique to assess building performance in a quantitative bioclimatic context to complement the qualitative description. Data or information about facts in the field of old houses were obtained from observing the physical traces of the building and interviews with the occupants of the house. Analysis with the response surface methodology will show building optimization in achieving thermal comfort with energy efficiency efforts in old houses in Kampung Peneleh, Surabaya City with various levels depending on the architectural style of the building (Javanese House, Indische House, Yankee House, Modern House). The good thermal performance of old houses can be a precedent in the bioclimatic architectural design of houses in dense settlements such as in urban villages.
