Information regarding green buildings,renewable energy resources etc would be helpful.
Dear Ajay,
Your question is so general in considerations. Green buildings and renewable energy have common benefits. you can refer to links below to more information.

Dear Ajay
All vernacular systems are Eco friendly construction practices. Cost reduction is entirely a different issue.
As said by Asif Ali do refer the literature available of Laurie Baker and Hassan Fathy. I will also advise you to visit following link
www.auroville.org
At Auroville nice and impressive work is being done on sustainable and eco-friendly construction.
Yes there are tremendous approach for it. Normally to go with this approach, you need to select the location and make your plan accordingly and your plan need to encompass sustainable site selection, Passive Heating and Cooling, Water Efficiency, Waste Management Efficiency, Eco friendly and accessible Material selection, Open space etc. If you can study these individual component and can design your green building accordingly than you can have very effective as well as economical solution. Normally design of one place would be somewhat difficult to corporate in other place as the location, climatic condition and many aspect alter the circumstance so green building of India might not be considered as green building in Bhutan. The Concept of individual component and collaboration with environmental and consideration of these design of your own as per your experience and knowledge can benefit you a lot and can direct your approach for economical and sustainable solution, Thank You
Dear Mr. Ajay
Light weight technology houses with passive environment control system can be made cost effective. The use of non renewable building materials can be considerably reduced in such houses and thus they will be Eco-friendly. Please see the attached links for an example.

The key is to work across budgets rather than each trade having a fixed amount of money. Spending more on the envelope will reduce heating and cooling loads, which will shrink or potentially eliminate certain mechanical systems.
A project I'm pursuing right now is considering several energy savings measures to reduce peak power in order to avoid building a new multi-million dollar electrical substation.
Reusing construction materials rather than buying new materials can be cost effective. Recycling construction waste avoids tipping fees at landfills.
You have to look for opportunities and explore them as many are location and project specific.
Dear Ajay,
As others have pointed out it is a broad question which you are asking, but also quite an important one if eco-construction is going to become mainstream. In general you have to look at the 'whole-life costs' of any project to make a valid comparison between what is expensive and what is cheap over the entire life span of a project. As such you might want to read up on whole life costing or life cycle costs. This is very much a function of operational energy consumption and energy prices as well as cap ex and ongoing servicing costs. It is fairly simple to build yourself a basic whole life cost model and there are also many software packages for this.
Before coming back to specific construction methods and technologies, I would mention that costs are typically compared on a per m2 of internal (usable) floor area and therefore your design cost optimization should be carried out on this basis. As such you will find that compact (energy efficient) forms are inherently also the most cost effective. When looking at construction cost optimization you can do this on an element by element basis whilst also accounting for the energy savings potential of any thermal elements or technologies which generate energy, as well as any feed-in tariffs or grants for energy generation. Off-site fabrication using modern methods of construction (MMC) is driving down conventional ecological building construction times whilst also reducing wastage and labour costs. If you would like more information on this interesting topic including some worked examples you might like to look at the economics chapter in the following book which I recently co-edited. The Passivhaus Designers Manual will be available in print in a few months time http://www.taylorandfrancis.com/books/details/9780415522694/
yeah there are lot of practices which can helps in controlling the cost
major saving are the by preventing constructions waste on sites, know the detailed use of any kind of the buildings, design for disassemble, need to design the construction very smartly, document construction for LEED, recycling the waste on the construction site, producing alternative power supply.
