Building Materials


The myth of green building

There is no question that India and other parts of the still-under-construction world must build green. The building sector is a major contributor to climate change and local environmental destruction because of construction materials used; energy expended for lighting, heating and cooling; and water consumption and waste discharge. This is the threat. There is an opportunity as well.

Lift your head from the sand

The outrage over the suspension of an official, Durga Shakti Nagpal, for simply doing her job—check illegal sand mining in the rivers of Uttar Pradesh—has highlighted a crucial issue. It is now evident that illegal mining of sand from rivers and beaches is rampant and the underbelly of this industry (I’m calling it industry for want of a better word) is powerful and connected. Worse still, all this is happening in violation of the orders of the apex court of the country.

A green facade

Building green is definitely important. But equally important is to know how green is a green building. Take the glitzy, glass-enveloped buildings popping up across the country. It does not matter if you are in the mild but wet and windy climate of Bengaluru or in the extreme hot and dry climate of Gurgaon, glass is the in-thing. I have always wondered how buildings extensively using glass could work in such varied climatic zones, where one needs ventilation. Then, I started reading that glass was green. Buildings liberally using glass were being certified green. How come?

Green buildings: it’s common sense

Frenzied growth in real estate and changing lifestyle in Indian cities are inciting resource guzzling. Architects have innovative ideas to build green homes
