The impact of climate change upon our lives and livelihood are mainly due to the activities in buildings polluting the atmosphere and higher usage of non-renewable resources to fuel our growth and development. Passive design emerges as one of today’s most meaningful ideas in architecture and planning. It is based on understanding that our resources are limited and their careless usage may lead to human and environmental crisis.
Consumption of non-renewable energy resources for heating, cooling and lighting of buildings, accounting for about 45% of total global energy consumption, also a major contributing factor to global environmental pollution and global warming. It is true that the majority of this consumption today is in the developed world, but tomorrow it will apply to the presently developing world.
What is Passive Design? Passive design counters to the local climate and site conditions in order to maximise the comfort and health of building users while minimising energy usage. The vital element in designing a passive building is to take the best advantage of the local climate.
Need for Passive Design: Incorporation of passive techniques in a building design helps to minimize load on conventional systems such as heating, cooling, ventilation & light which in turn helps in improving the efficiency in energy consumption in the building. Passive strategies provide thermal and visual comfort by using natural energy sources.
