Human health and human comfort have been perceived as the most important parameters while assessing the indoor environment. Developing countries, constrained by extreme environmental conditions, poor building technologies and limited financial resources, find it difficult to adopt expensive technologies for a better indoor environment. Passive architectures, such as inclusion of solar chimneys, can reduce adverse health effects due to indoor contaminants, while green areas can be developed to reduce outdoor contaminants in the ventilation component. An analysis of bioclimatic architecture, assisted by a wind tower system, is presented for a better indoor environment.
