<Example1> A house like the old days.(built in 20 years ago)

My house is Japanese style house.My house was built by my grandfather and grandmather who had been concerned with building houses. So my house strains on many points. Its wall is soil-wall. There are Western-style room in my house. But most of the rooms are Japanese-style rooms. So I can feel warmth of wood. My house's good points are what has many big windows. It can intake light and send in wind. The southward window which is 3 meters high can intake light and warm indoor air without stove. My house's good points also are many plant. My grandmother is proud of the garden. The big windows take part in looking the garden as enviromental device.

My house has fault. It cannnot warm rooms soon. My house hasn't floor heater herefore use stoves and kotatu.Because each of the rooms is large, many energy use to heat rooms. because windows are big, it lose fever.

How to use my house as an environment-house with little environmental load.

・Use special glass for a window and lessen heat loss from a window.
・The performance of heat insulation of a wall is improved and the
heat which escapes from a wall is reduced.
・In order to prevent the solar heat from a window summer,
use the high curtain of interception.
