Role of green buildings to Environmental Efficiency enhancement
Green Buildings need not be green in colour. The crux of green building movement across the world is to optimise human comfort,convenience and well being with the least energy consumption by the use of renewable energy and by achieving circular economy.
Recent trends of incorporating many trees in buildings in artificial ecosystems may not be ’true-green’ in spirit.Thousands of trees in a building may be a show piece but economically not feasible to recommend as a policy measure. Trees themselves are put into stress as not being in a natural ecosystem.What the world needs today is to contain the ecological overshoot for which the ecosystem approach is highly essential to improve the biocapacity of the earth.
The concept of Green Buildings envision a new approach to save water, energy and material resources in the construction, operation and maintenance of the buildings and can reduce or eliminate the adverse impact of buildings on the environment and occupants.
Green building concept rightly coincides with the environmental efficiency index HD/EFpas it concentrates on increase in human development by increasing the comfort level with reduction in ecological foot print.
Salient features of the green building contributing to reduction in ecological foot print are
Effective use of soil and landscape
Efficient use of water
Energy efficient and eco-friendly equipments
Effective control and building management system
Use of renewable energy
Use recycled/recyclable materials
While the salient feature which contributes to human development are
Improved air and water quality for health and comfort resulting in
Unlike a conventional building green buildings intends to achieve operation and maintenance savings, reduction in initial investment while there is strong concern for human comfort, indoor environment and safety.
