PASSIVE SOLAR ARCHITECTURE INTRODUCTION:1 The last two decade has witnessed a severe energy crisis in developing countries especially during summer season primarily due to cooling load requirements of buildings. The energy consumption in buildings is quite high and is expected to further increase because of improving standards of life and increasing world population. Air conditioning use has increasingly penetrated the market during the last few years and greatly contributes in the upsurge of absolute energy consumption. INTRODUCTION 2: Buildings account for at least 40% of energy use in most countries. The construction sector in India is witnessing a fast growth due to several factors. Some of the key growth drivers are increased demand for housing, strong demographic impetus, expansion of organized retail, increased demand for commercial office spaces by multinationals and IT (information technology) hubs, and coming up of SEZs (special economic zones). The gross built-up area added to commercial and residential spaces was about 40.8 million square metres in 2004/05, which is about 1% of annual average constructed floor area around the world, and the trend shows a sustained growth of 10% over the coming years. With a near consistent 8% rise in annual energy consumption in the residential and commercial sectors, energy consumption in buildings has seen an increase from a low of 14% in the 1970s to nearly 33% in 2004/05. This is directly related to higher greenhouse gas
