Energy Saving Building Construction

I just finished constructing a house in Texas USA. I used insulated concrete forms. Specifically Nudura products. These were very user friendly and an engineering firm I hired for my environmental work said I have a realized R value of 54. My house in indescribably comfortable and my first two electric bills were in the low $40. Large windows allow sufficient natural light.

Thanks,

Thats terrific. I sell another ICF product in upstate NY (Rochester) and am amazed at the reluctance many builders and other professionals exhibit when I give them the specifics on R Values and other benefits. We are currently planning a 1600 sq. foot home in which we are aiming for a heating budget of $30 - $40 per month. It a proof is in the pudding approach to demonstrate for the entrenched architect or engineer that amazing results can be achieved for less money than you would expect.

There are a plethora of things you could do, but as for the best or most cost effective, that requires a lot more information on the parameters of the building.

Here are a couple ideas though, to get you started.

straw bale construction - thick walls with a very good insulation value.

Adobe wall construction could also be used.

These are just quick-links that I picked up, but they will inform you on what those two technologies are.

I would also suggest some sort of Ground-Source cooling. This is basically burying a long looped tube in the ground and running a heat exchanging fluid though it. The ground (12-18" below the surface) stays at a pretty constant temperature, normally between 65 and 70 degrees Fahrenheit. Then a small pump and splitter system pumps this fluid through piping imbedded in the floors to cool the building. Only the power to circulate the fluid is used instead of standard air conditioning which removes head form the air in the house.

What it doesn't do is circulate air, so an air circulatory system will still need to be put in place, and that should be designed to use the cooler air leaving the house should pre-cool the incoming air.

There are many commercial versions of this type of geothermal cooling (and heating) available.

Windows should be triple pained and glazed against thermal transfer. How much insulating value they have can be customized and basically is just a matter of cost.

Since I am assuming You are in a very sunny climate, you should put in a thermal barrier in the attic space to stop the radiated thermal energy. There are many varieties of this as well.

There will be a new forum coming up soon on sustainable low-energy housing coming up on the site, probably early in April, which I will be admining, so stay tuned and I will let you know when it launches. We will be covering many issues that will mesh well with what you are looking for.

"I would also suggest some sort of Ground-Source cooling. This is basically burying a long looped tube in the ground and running a heat exchanging fluid though it."

-A simpler method would be to bury tube or pipe from a shaded area to allow ground cooled air to enter the building.

"What it doesn't do is circulate air"

-A flat black "chimney" on top of the structure would provide convection current to draw cool air in from the pipes and vent hot air out.

hi

try to contact Global Evolutionary Energy Design (GEED)

www.geedindia.org

it is in Jamia nagar , New Delhi

ok

I don't think that's going to help him much since it's full of Political Posturing and very lean on actual information. It reads more like a funding grab for government money.

Hi,

I thınk you can fınd ın the followıng web sıte that you need

I would also look at the African round house construction with high ceiling and a cooking area in the center and an opening at the top. Air flow makes the house livable. I assume you will be cooking in this house even though you did not mention isolating the cooking area.

We have a Viable and Economical solution, available in India.

Hi you could try Phase Change Materials - as wall insulation - which will absorb the day's heat and release it at night.

There is quite a big industry in India supplying these materials for insulation of communications installations.

There is a plant in India producing prefabricated composite modules that satisfy all your requirements. You can make a building 50 square meters, 5,000 square meters, or more. Here's the link to their website.

Compressed Earth Block would be a good alternative for the outer walls. More significantly, high ceilings can reduce indoor heat significantly- look around at the difference between older construction in the tropics and newer construction designed for air conditioning. Another factor is providing for air circulation- I like ceiling fans, but there are alternatives- even some natural flow concepts. Study the architecture of the older, colonial-era construction in India to figure out how it was done before we got lazy and started using air conditioning...
