Is a floor surface, 15 is an old cap, and 16 is a new cap.

As shown in FIG. 1, this building is a four-story building. The left side of the figure shows a state where the new outer wall 1 is attached, and the right side shows a state where the new outer wall 1 is removed. Window 3
Is installed on the old outer wall, and the window member is attached to the old building frame by using the window member of the old building as it is, removing the window member of the old building and attaching a new window member, etc. ing. However, the window member is not limited to this. Further, a window member may be attached to the new outer wall side to form a double window, or the old window member may be removed and only the new outer wall side may be replaced. A window may be provided. To mount the new outer wall, the horizontal base material 4 is fixed on the old outer wall 2, the vertical base material 5 is mounted via a base fixing bracket (not shown), and the new external wall 1 is mounted on the vertical base material 5. In this embodiment, the horizontal base material 4 is provided so as to pass in the horizontal direction, but a part thereof may be cut off. In addition, between the windows in the horizontal direction, a vertical base material 5 is disposed so as to pass in the vertical direction.

An embodiment of the mounting structure of the base material will be described with reference to FIG. FIG. 2A is a top view, and FIG. 2B is a side view. Note that the old outer wall 2 is hatched only in a portion near the surface to make the drawing easy to see. An anchor bolt 6 is driven into the skeleton from the old outer wall 2 to fix the base fixing bracket 7. The horizontal base material 4 is fixed to the base fixing bracket 7 by welding, bolting, or the like, and the support member 8 is fixed to the base fixing bracket 7 by welding, bolting, or the like. Next, the vertical base member 5 is fixed to the support member 8 by welding, bolting, or the like, and the base member is attached to the old outer wall 2. The new outer wall 1 is attached to the vertical base material 5 via the panel fixing bracket 9.

In the space between the new outer wall 1 and the old outer wall 2, the length of the support member 8 is selected so that piping and wiring can be accommodated.
As shown in FIG. 3, the pipes and the wiring are arranged between the left and right and upper and lower sides of the window 3. FIG. 3 shows the piping 10 for air conditioning, but is not limited to this. It may be a gas pipe, a water and sewage pipe, a distribution line or a communication line, or a distribution line or a communication line itself. As the communication line, a connection line between each room in the building and the outside such as a telephone line, a coaxial cable, an optical wiring, and a control line can be arranged.

[0015] The pipes and wiring are connected to facility equipment arranged in necessary rooms. FIG. 3 schematically illustrates a case where the pipe is drawn into the ceiling side or the floor side.
The part shown by the dotted line is not connected to the piping shown in the upper part, indicating that a different piping is performed. Therefore, the pipes and wirings may be connected to the equipment alone, or may be connected by branching off from the main line. These pipes and wires provide a space between the old and new Kasagis and are connected to rooftop equipment. The rooftop equipment is an air conditioner that supplies air for cooling and heating, a cooling equipment that supplies cooling water to an air conditioner provided on each floor, and a power supply to each floor, with the equipment in each room as a terminal device. Power receiving equipment, communication equipment, etc.
It is the main equipment. A part of such main equipment may be provided on an appropriate floor.

Also, ventilation can be performed through this space. A vent is provided below the new outer wall to take in the outside air, and a space is provided between the old and new Kasagi above to serve as a vent. Although the vent is described later, a vent that can be shielded is preferable. The lower vent is provided with a fixed or movable louver as a vent in the area A near the ground surface of the new outer wall on the first floor, and the window 3 provided on the first floor in the area B. In the area of C, a vent provided in the upper frame of the window frame provided on the second floor is shown in FIG.

The relationship between the building and the solar radiation is such that in summer, the temperature is high and the solar radiation is strong. Since the temperature of the wall irradiated with sunlight has a large temperature rise, heat taken in from the wall enters the room, and the cooling effect is reduced. Therefore, it is advantageous from the viewpoint of energy saving if the space between the old outer wall and the new outer wall is ventilated to prevent the heat taken in from the wall from entering the room. If the ground near the building has an environment in which the temperature rise is small and lower than the air temperature due to shrubs, grass, and the like, it is preferable to employ the ventilation holes shown in the area A.
In an environment where the ground near the building is paved and the radiant heat therefrom is large, the temperature at a height that is far from the ground is lower. In such an environment, depending on the situation, it is better to take in air from the first floor part shown in the area B or the second floor part shown in the area C.
The introduced air flows upward and escapes as indicated by arrows. Due to this flow of air, the heat absorbed by the outer wall surface can be discharged upward, the temperature rise in the room can be reduced, and significant energy savings can be realized.

In winter, vents are blocked to prevent airflow. The new exterior wall absorbs sunlight and keeps the warmed air from escaping, while suppressing the exterior wall cooling and using the air layer as a heat-insulating space, thus achieving significant energy savings. Sound insulation characteristics are also improved.

FIG. 4 shows an example of the arrangement of equipment for air conditioning and piping. FIG. 4A is a cross section passing through the window,
FIG. 4B is a cross section between the windows. As shown in FIG. 4 (A), for example, the above-described airflow is transmitted through a window 3 provided on the second floor.
