Abstract

Development of the housing sector has now spread to the suburban areas of Denpasar; even some rural areas in Bali have become targets of housing developers. Designing and arranging of houses through ergonomic intervention comprises one of several efforts for improving the houses’ quality in terms of their natural comfort. The ergonomic intervention should meet such criteria as to be technically applicable, less costly, energy saving especially that of electricity, socio-culturally convenience, and environment friendly. This experimental study being reported applied a treatment by subject design, in which eight houses were selected as sample, located in the housing complex of Perumahan Nuansa Kori Sading Mengwi Badung. Of the eight sampled houses, each two houses faced north, south, east and west, respectively. Twenty six occupants of the eight sampled houses were interviewed using a questionnaire. All samples were selected by stratified random sampling. The ergonomic intervention comprised remodeling of ventilation and windows of all the sampled houses. Data collecting of objective comfort was carried out before and after intervention i.e. at 8 am, 10 am, 12 pm, 2 pm, 4 pm and 8 pm, by measuring temperature, humidity, light intensity, and airflow. Data of subjective comfort were collected by questionnaire, which had been tested earlier for its validity and reliability. The results showed that (1) before intervention the average of wet temperature was 23.66 ± 1.36 ºC, after intervention was 23.09 ± 1.20 ºC; (2) before intervention the average of dry temperature was 28.76 ± 1.07 ºC, after intervention was 27.88 ± 0.73 ºC; (3) relative humidity before intervention was 73.44 ± 4.37 %, after intervention was 72.63 ± 2.73 %; (4) natural light intensity before intervention was 134.94 ± 71.69 lux, after intervention was 229.69 ± 114.53 lux; and (5) the average of airflow before intervention was 0.10 ± 0.04 m/sc, after intervention was 0.31 ± 0.08 m/sc. The conclusions could be arawn are that ergonomic intervention by remodeling ventilation and windows of houses type 36/120 could improve objective comfort by 12.4% (p<0.05), along with increase of subjective comfort of the occupants of the houses facing all directions. This study suggests that ergonomic intervention should be applied since early in the construction of houses in order to make them cheaper, healthier, and more comfortable.
