A green building can be defined as any building that is sited, designed, constructed, operated and maintained for the health and well-being of the occupants, while minimizing impact on the environment.
A green building is a structure whose environmental responsibility and resource-efficiency spans its entire
life-cycle. It enables the efficient use of resources, protection of occupant health & improvement of productivity and reduction of waste, pollution & environment degradation.
The aim of a green building design is to
An extensive amount of energy is consumed to heat and power our buildings. This energy is mainly generated from burning fossil fuels like oil, coal and natural gas that let out huge amounts of Carbon Dioxide (CO2), the most widespread greenhouse gas. There are also other ways in which buildings emit Greenhouse Gases (GHG), like construction debris in landfills generating methane and manufacturing of building materials causing GHG emissions.
In India, the construction sector is growing at a rate of 9%, causing a rapid rise in energy demand in urban areas where buildings alone contribute about 40% of the total GHG emissions. Hence it becomes imperative to reduce the energy use and GHG emissions produced by buildings so that the pace of global climate change has a slowdown.
Energy efficient buildings or green buildings, address the above concerns and save energy by about 40%.
