| Abstract | The study compares the environmental conditions in terms of comfort in two different cases. One is based on the traditional urban forms for housing and the other more of less a deviation of a borrowed concept sometimes referred to as modern or imitative development. Though the two houses selected are in the same city, they have different planning concepts, which is evident in the two layouts. The two houses selected were put under observation for more then six weeks time. out of which observations of thirty eight days were selected for analysis. During this period Dry bulb Temperature, Wet Bulb Temperature and Air flow were noted at 0630, 1030, 1430 and 1830 hrs. This was done in both the cases for inside and outside, so as to have a clear picture of the behaviour of the houses and the residential envelope, and to establish the difference between the two cases if it exists. In addition to that the effect of induced air flow by mechanical means i.e a ceiling fan, were also studied. In the analysis based on separate parameters, when inside conditions are compared to outside, the traditional house is hotter by 1.4c at 0630, but remains cooler by 2c at 1030 and 2.9c at 1430, respectively. This difference from outside is reduced to 0.9c at 1830. In the case of the modern house, it is hotter by 2.7c at 0630, although remaining cooler by 0.4c at 1030 and 1.1c at 1430. But again it becomes hotter by 1.4c at 1830. in comparing the two houses with each other, the traditional house is found to achieve a lower mean temperature value inside by 1.3-1.7c. For outside, the traditional house has a lower mean value by 0.4c at 0630. This difference almost becomes zero at 1030. But at 1430 and 1830 the traditional house has a higher mean value by 0.4c and 0.9c, respectively. A difference in humidity is established theoretically, but the vapour pressure remains the same. No difference in air flow was found inside the two houses, but outside the traditional house it is more. The analysis based on single parameter shows a difference of 0.4-0.8 CET between the two houses inside. For outside conditions the modern house has a higher mean value by 0.4 CET at 0630. This difference is reduced to 0.3 CET and 0.1 CET at 1030 and 1430, respectively. But at 1830 the traditional house has a higher mean value by 0.3 CET. Thus all the analysis show that the traditional solution has a more comfortable environment, but the difference in the two cases is still a question needing further research, perhaps more of a subjective nature. |
