What green building materials are available now?

Salvaged, Recycled, or Agricultural Waste Content these are the materials used to produce a building product which is  key determinant of green.For eg Many salvaged materials used in buildings (bricks, millwork, framing lumber, plumbing fixtures, and period hardware).

Indirect Adiabatic air conditioning  technology offers lowest specific energy consumption. It also offers 30% or more fresh air to exceed the IAQ norms for LEED Buildings.

The technology enables Building -Ambient connectivity to  make full use of free cooling even during hot summers .Does not use any chemical refrigerant for cooling.

The Air Handling Units based on this technology , are now available in India.Intersted ? you can have a look at www.unidyne-energy.com

The  Air Handling Units reduce operating costs by 50-60% and may also reduce the capex ,depending on the project location.Pay back is always  less than 2 years. 

As far i know in india all materials and buildings are made of lessenergy, waste, reusable etc., in the past traditionally and present too.

The terms green building, green building materials, sustainability, LEED certification are indirectly or directly related the use of lessenergy, waste, reusable etc., in the process of building and in its use for the purpose. All these related to envrionmental and ecology 

There is no need for green building or LEED certifications for most of building, its just to increase the project cost and making fools by western countries in terms of sustainability, envrionmental and ecology

Tradiational building methods should be adopted for green building,We may incoorporate some new material but depending upon the area ancient buildings were very close to green buildings.So inspiaration from tradiational methods must be a better idea .It may vary from place to place .

Is cement,concrete debris easily disposable ? When we are constructing multi storeyed buildings, are we thinking what will be impact of tonnes of concrete rubble ,debris that will be generated after century when that building will be dismantled by next generations? Our forefathers used stones & lime combination to construct buildings.Now when new building is constructed in place of old one ,stones, wood can become easily recycleable as a part of environment but what about concrete?New builders should think over it.

The main focus should be on reuseability of material & resources such as water harvesting , reduce polution of night aura by providing shaded street lights , alternate fuel (such as elec. & battery operated vehicles)
