Very good ideas but as far as India goes, adoption might have to consider monsoon, winter-snow in some, which again might require more tweaks based on more tests. Another aspect is how real-estate and building construction works in India, across rural and urban regions.Some of the regions have strong clouts of companies that control building/development in urban spaces, while supplies and other aspects in rural region. Can see the realties changing and newer construction projects taking in newer & greener designs, in both urban and rural regions, but its got a long way to go!
