How can you build a house so it saves energy?

Question

For example:solar power, shower heads,lights e.t.c.

Answer 1

No I cant. Im sure someone can, but not me.

Answer 2

I have a camping trailer. It use 12 Volts DC, 120 Volts AC and Propane. What I noticed most were the lights that use 12 volts, they just old Light Bulbs like cars used before the high dollar bulbs. The Refrigerator use Ammonia and can run on a little flame from propane, 12 volts DC or D size batteries! It takes a while to get cold when it first start, but, once it get going, I can freeze stuff in the bottom. Though there may be a size limit.
So, I been reading up on different Refrigeration and Electric Generation options, solar, wind, thermal etc. I thinking a house made to run off 12 volts DC could be more energy efficient, actually self sufficient.
Even now, in my house, we sit here watching TV with 2 laptops going and one light. I thinking, this could all be running on 12 Volts now and recharge tomorrow.
Another interesting thing is the Hydrogen Batteries. IF, they get this going. I watched something on TV and what was really cool? It showed the family coming home in their car and they plugged it up to the house. NOT to recharge the car, but, to power the house!!!!!

Answer 3

Double glazed windows.
Maximize the uses of sun for light and sin-light for heating in the day time. (lager windows)
use energy efficient bulbs.
LCD TV,monitor consume less power than CRT ones.
a adjacent house loses less heat than a stand alone because only two sides are exposed to weather and other sides are with the neighbors.

and most of the time it you who should be taking care of how much light is required at night time.

Answer 4

double pane windows, extra insulation, sky lights, motion sensors for the lights(might be a lil tricky if your just sitting there watching tv though, but i you fall asleep watching tv they will turn off which is a good thing) ceiling fans to circulate the heat/cool air...

Answer 5

heat it with geothermal energy. it will cost a lot to get it set up but you'll definatley save on energy.
