Use of traditional passive strategies to reduce the energy use and carbon emissions in modern dwellings

摘要

In India, traditional values as well as the timeless way of building compact residential environments is now threatened by new and foreign influences from the Occident. These influences are incompatible with the climate of the country and traditional culture of its people. [Schoenauer N. 6000 Years of Housing. W.W.

This study offers a classification of vernacular environmental design traditions across the subcontinent based on the Koppen-Grieger climatic regions and a detailed study of thermal comfort in traditional and modern dwellings, in two of the eight regions, using environmental performance modelling. The results show that traditional passive techniques provide a high degree of comfort for a longer part of the day while potentially minimizing energy use. Some problems were identified in adopting the passive strategies to the present context. For example, there are limitations in the use of traditional building materials, such as, earth, but suitable alternatives with similar properties can be readily adapted to the same effect.
