Building an Energy Efficient Home
There is just to know some important things to remember when building an energy efficient home. These are, insulation, air infiltration, thermal mass, windows and holes in the wall of the house lose about the same amount of energy.
Isolation is a means for detecting air causes death and facilitate the exchange of energy on a hot cold room to slow down. Most manufacturers use a fiberglass insulation. Personally, I prefer to use blown cellulose insulation. In America, we are at the high value of the insulation by a factor R. The R factor of insulation is a reference to the ability of insulation to slow heat transfer and R stands for resistance factor. The R factor is only part of the story. Insulation, a high R factor, but when the air moves through, it is almost useless. One of the things we recently is the construction of homes, Tyvek, a thin layer of breathable plastic membrane that stops the wind to use. In modern construction, we usually outside in the killing, siding, Tyvek, insulation and drywall. Usually results in what we and R-30 wall.
In other countries, they speak a factor U. The U factor is the input. And use of this factor is simply a combination of an R factor and the ability to resist air infiltration. Therefore, using the factor actually makes more sense than the strict R-factor. For example, a concrete wall, has a low R factor and a high U-factor, if the newspapers are made to fit closely together. A concrete house has a low resistance factor, because the heat transfer real easily. In order to isolate a concrete wall, you should insulate the outside wall. And that brings us to the mass.Windows thermal energy is a wasteful important. Each glass is a resistance factor of less than one. A window has a thermos resistance factor of about two or three, including the airspace. The windows over a house, the more expensive heat. Triple glazing has a resistance factor of about five years. A curtain covers the window completely, the resistance factor will increase to about 20. So draw the curtains will significantly increase the insulation capacity of a house.
Thermal mass is simply the amount of weight a certain temperature is reached and remain at that temperature. So I was at home with a brick floor, and many books and heavy furniture, lots of thermal mass. Once a house with a lot of thermal mass to reach a comfortable temperature, it tends to temperature for a long time remain, even after stopping the heat or air conditioning. Offices tend to have a high thermal mass. It takes a lot of energy to change the temperature of the thermal mass. Thus, we should leave the thermostat at the same temperature and it does not move up and down. Turn the thermostat at night and on again during the day wastes energy.
