Abstract:
Mud huts with burnt clay tiled roofs in Jharkhand, a state in the eastern part of India, are an integral component of the state’s vernacular architecture. They come in various shapes, with a number of them having a courtyard type of plan. In general, it is accepted that dwellings with compact planning show better thermal performance during summer and winter in composite and hot-dry climates. Alongside, it is also generally accepted that courtyard type housing is a climate responsive solution in composite climates. In this paper, three types of mud huts with courtyards, with varying perimeter-area ratios ranging from 0.3 to 0.8 are taken as a study and through temperature measurements in the south-side rooms, in addition to detailed software simulations of year round total number of discomfort hours due to excess heat and excess cold respectively, their thermal performance during the peak of summer and winter months are observed. The temperatures in the rooms with respect to outside recorded temperatures during peak of summer and peak of winter are plotted graphically over twenty-four hour periods. Thereafter, on the basis of the study, it is seen to whether compact floor plans show better thermal performance amongst the three studied types of courtyard dwellings.
