The Buildings are part of basic needs. It is for protecting us from Nature's extremes: cold, heat, wind and Rain. But these structures affect and shape our environment too. Constructing and op-erating buildings requires enormous amounts of energy, water, and materials and creates large amounts of waste. Where and how they are built affects the ecosystems around us in countless ways. And the buildings themselves create new indoor environments that present new environ-mental problems and challenges.
As the environmental impact of buildings becomes more apparent, a new field called green building is Arising to reduce that impact at the source. Green or sustainable building is the practice of creating healthier and more resource-efficient models of construction, renova-tion, operation, maintenance, and demolition.
Green building is a rational response to two driving forces – firstly, a new set of resource constraints facing the globe and secondly, to a demand for healthier, more productive environments for users. “Green building is a natural evolution of the building sector, responding to an emerging set of economic forces. It is not a passing fad, but the way things will have to be done in future”
