<Example3> An import house (built in 4 years ago)

My house is an import house from Sweden. Swedish interior has distinguished insulating effect because it's too cold in Sweden. And what's more, the walls pinch insulators and all windows are three sheets of glasses. So if I use a hot carpet, I don't have to turn on the heat in my room. Of course, air conditioner effectives in my house remarkably in summer.

But even this house sometimes use energy. I want to aim more comfortable house to fix my eye's on the future.

My house is done like this to reduce environment loads and to take an environment-like house ...

・I must adopt "passive design".(I can keep comfortable room by less energy.)

・I need to place solar system and cover the energy by solar power.
