Dear Saxena ji,

Thank you for inquiry.

West facing windows can be a big source of heat, first measure which you can explore is to add a chhajja (sun shade) on the window if you don't have one already. West sun will also require some vertical shading device too. Explore options of having vertical fins on the side of the windows.

Your second question regarding roof insulation using thermacol. Thermocol can be used, but it will absolutely need a good protection. This protection is generally a layer of 3''-thick PCC (plain concrete) with joints every 6 feet, and that entails using a very strong, high-density thermocal, capable of supporting permanently the load of the PCC. Ordinary thermocal won't do. Then this PCC can be covered with white tiles. It's a relatively advanced solution, which addresses both roof insulation and cool roof. It is best if you can do this.

What really is happening is that they are trying to kill us and future generations with all these. ...SHAME SHAME
Will the MEDIA personnel take up this task to make BIG campaign against these ridiculous so called committee. Take this forward make it know to everyone ...

Why all these are not applicable to Tuticorin port or the one planned in AP or WB ?

How come Andhra is left out of the mining loot story ? It is good for the nation if we learn to keep environmental and political affiliations apart . Also everyone knows of the problems ....it would be great when environmental publications start focusing on the solutions as India has become a net importer of iron ore from a net exporter since mining was banned in some states and that has added to the rising current account deficit every month. In many parts of the world people are involved in sustainable mining. We in India need not re-invent the wheel but only follow those practices. Instead of that we are banning existing mining blocks which have already been devastated environmentally and planning to issue licenses in green field areas that will involve more cutting of forests.

The existing areas under mining are inefficiently mined, only from the surface to keep mining costs to the bare minimum. Why is that happening? Is anyone talking about it. Where are the regulatory norms and the regulators which can be easily put in place, considering the enormous revenue generated from the resources and the technology advances of satellite imagery. Every cubic feet of mining resource extracted can be today monitored at a very reasonable cost by using technology if there is a political will. It is the MOEF that has to educate itself adopting global best practices and then enforce the norms, without political bias that today permits Jindal but not Vedanta to put up bauxite mining projects in India.
