How green buildings can be Energy Efficient?

With the increasing energy prices, diminishing reserves of conventional forms of energy, & increasing Green House Gas emissions, 'green buildings' are the need of the hour. It increases the efficiency energy through techniques made while constructing the building.

To my opinion I think they should avoid the use of air conditioner, & use maximum no of ventilators constructed in such a way that cool air spreads in the room. Then usage of natural sun light instead of tube lights & bulbs at day time & lights maintained by solar energy for the light required in night.

I agree with the ideas propose by Mr C Nijagunaradhy. Yes we should design the green building and should be ready to incur associated cost of it.

I dont agree with Ms Shikha on cutting the luxury items like air conditioner etc. Look we are earning the money to have the luxury. But yes agree with the concept of day lights etc.

Let us take a tangential view to this problem. I propose to use the radiant energy / Vaccum energy i.e. using the devices which have the COP over 2. Hey I am not joking it is possible. If you dont belevie me then google the John Bedini, Tom Bardent etc.

Other then the radiant / vaccum energy, we must explore the possibility of using the concept of Wind, Solar, Day light [somehow this concept died its own death], energy saving lights etc etc.

Any body wants more information  or join hands with me to develope John Bedini stuff, drop me a mail on pvar06@yahoo.com

Sorry for those, who are unable to understand this concept.

Have a nice time.

Hi,it was very enlightening reading the various wonderful ideas from my friends here.We have discussed green buildins as ....SOMETHING DIFFERENT...U KNOW...like some different species...from an alien country...pl get my point.               NOW  where do WE LIVE?A City/Town...say 50-1000 sq km of land area heated by the tropical sun.These 50-1000sq km of surface are mostly concrete rooftops of buildings some 10-20-50,even 100 year old structures.Concrete under the sun acts just like stone,it absorbs heat retains it and like an oven radiates it in all directions heating the air both above and below. LET US STOP ACTING that we can redesign these into buildings,or that anybody would even think of doing that.I would rather suggest a MINIMALISTIC APPROACH.Ie doing what we can with MINIMUM OF EXPENSES and MINIMUM of CHANGE.So what can be done???Two things come to mind.Firstly if we can plant CREEPERS covering the roof of buildings it will mean lesser ammount of solar radiation hitting the roof in the first place which means that lesser heat enters the building thus bringing down A/C BILLS.It also means that the air above the roof is less heated up by the concrete which would give us a cooler city if this technique is adopted widely.This would involve BARE MINIMUM expenditure,no redesigning of any building,can be widely adopted and has been proven to bring down A/C costs by upto 40 percent.The second is the more capital intensive approach of adopting the most energy efficient LIGHTING Technology like L.E.D and C.F.L as these would not only bring down the direct expenditure on lightinng but also the indirect but substantial cost on A/C as these have been known to give off a lot less ammount of heat than conventional lights.Let us also remember the 40 percent of our COUNTRYMEN who do not have a light-bulb in thier homes to light up thier lives and hope that the GREEN MEASURES we adopt will help save the electricity that will some day light up thier lives.
