Description

The invention disclosed in the present application relates to a building with a courtyard, and particularly to a building with a courtyard, which is characterized by a lighting method for the courtyard.

In houses and other buildings, it is common to provide a courtyard on the premises to enhance the feeling of openness from the indoor space. As a form of such a building, for example, in Patent Document 1 and the like, a courtyard is provided in an outdoor area surrounded by an L-shaped or U-shaped plan view by the main building portion of the building, and an indoor living room facing the courtyard or the like. It is disclosed that the courtyard can be viewed from the dining room. In such a building, it is common to plant or wall the courtyard near the boundary between the courtyard and the outside of the site to block the line of sight from outside the site to the courtyard or indoors. In a building with a courtyard that takes privacy into consideration, the opening of the window facing the courtyard is widened to improve the view from the indoor side and create a sense of unity and continuity between the indoor space and the outdoor space. Can be enhanced.

Furthermore, in buildings with such a courtyard, lighting fixtures such as garden lights and spotlights are often installed around the courtyard to light up the plants so that the scenery of the courtyard can be enjoyed even at night. .. For example, Patent Document 2 proposes various lighting facilities for lighting up the planting of the exterior portion of a house.

It is desirable that the conventional courtyard is not only viewed from the indoor side, but also effectively used in various ways as a space for relaxation and gathering. Therefore, the inventors of the invention disclosed in the present application recall that a resting corner is provided in a corner of the courtyard and furniture or the like is arranged there to create an "outdoor living space (outdoor living)" where people can relax. However, we examined the specific spatial composition for that purpose. And, in order to realize such an outdoor living space, special consideration is required to balance the lighting effect seen from the indoor space and the lighting effect seen from the outdoor living space, especially with respect to the lighting at night. I found that. In other words, lighting that is forward-lit when viewed from either the indoor space or the outdoor living room is likely to be backlit when viewed from the other, creating a shadow that makes the planting etc. illuminate from the back side. It becomes unnatural. In addition, if priority is given to the lighting effect when viewed from one side, there is a tendency for problems such as the light source fixture getting into the eyes and being uncomfortable when viewed from the other side.

The invention disclosed in the present application has been made in view of the above circumstances, and when the courtyard is viewed from either the indoor space or the outdoor living room space, an obtrusive light source does not come into view, and the courtyard is planted, etc. The purpose is to provide a house with a courtyard that incorporates a lighting method that creates a gentle scene that looks like it is lit by the moonlight.

In order to achieve the above object, the invention disclosed in the present application is configured such that a courtyard is provided along the outer wall of the building, and the courtyard can be viewed from the indoor space of the building through the window surface opened on the outer wall.

Hereinafter, embodiments of the invention disclosed in the present application will be described with reference to the drawings. 1 to 8 show an embodiment of a building with a courtyard 1 according to the invention disclosed in the present application.

This building 1 with a courtyard is a two-story building, and the entrance 11, the entrance storage room 12, the living room 13, the dining room 14, the kitchen 15, the pantry 16, the housekeeping room 17, the toilet 18, the stairs 19, etc. are arranged on the first floor. The living room 13, the dining room 14, and the kitchen 15 are spatially integrated, and in the living room 13 and the kitchen 15, the window surfaces 41 and 42 having large openings facing the courtyard 3 are continuous in an L-shape in a plan view. It has been opened.

The courtyard 3 is provided in a corner area surrounded by a living room 13, a kitchen 15, and an entrance storage room 12 in a substantially U-shape. The courtyard 3 is a space open to the outside air on the site of the building 1. Soil and stones are laid on the ground, and large and small trees including a symbol tree 31 that is higher than the human eye and a ground cover are planted to form a landscape of a small garden.

The courtyard 3 is continuous with the terrace 5 arranged so as to surround the outside of the building 1 in a corridor shape. The terrace 5 is also a space open to the outside air, and the dining room 14 is provided with a window surface 43 having a large opening that allows access to the terrace 5 side. Natural stones are pasted on the walking surface of the terrace 5. The upper part of the terrace 5 is covered with the back of the balcony 21 on the second floor to prevent rain, and the same ceiling finishing material as the dining room 14 and the living room 13 is pasted on the back of the eaves. Large and small trees are planted between the terrace 5 and the boundary line of the site to block the line of sight from outside the site.

At the end of the terrace 5, an outdoor living space 6 is provided so as to overlap a corner of the courtyard 3. The outdoor living room 6 is surrounded on two back surfaces by an L-shaped wall body 61 in a plan view without openings, which is erected along the site boundary side of the terrace 5. Furniture 62 for resting is installed on the entrance side of the wall body 61 so that the courtyard 3 can be enjoyed while relaxing and eating and drinking easily.

On the second floor of the building 1, a second living room 22, a Western-style room 23 as a master bedroom, a walk-in closet 24, a washroom dressing room 25, a bathroom 26, a second Western-style room 27, a children's room 28, etc. are arranged. .. In the second living room 22, a window surface 44 having a large opening facing the atrium above the courtyard 3 is provided. Further, a balcony 21 is provided so as to surround the outside of the building 1 and the courtyard 3 in a corridor shape, and access from the master bedroom and the children's room 28 is possible. The terrace 5 on the first floor is arranged directly below the balcony 21.

In this building 1, the main building part where the living room 13 and the dining room 14 are provided and the outdoor living room space 6 provided apart from the living room 13 are opposed to each other with the courtyard 3 in between. The courtyard 3, the terrace 5 connected to the courtyard 3, and the outdoor living room space 6 are semi-outdoor spaces corresponding to the expansion area of the indoor space, and can be regarded as "internalized exterior". When the courtyard 3 is viewed from the building 1 side and when viewed from the outdoor living space 6, the impression is different, and the resident can enjoy the diversity. Then, even at night, in order to optimize the lighting effect when viewed from each side, in this building 1, toward the courtyard 3, from the building 1 side and from the outdoor living room space 6 side. It has a structure that illuminates from the direction.

The lighting fixture 71 on the building 1 side is attached to the lower surface of the eaves 8 of the roof protruding from the upper part of the outer wall of the building 1 facing the courtyard 3 toward the courtyard 3. For this luminaire 71, for example, a universal downlight whose irradiation direction can be changed can be preferably used. As for the downlight, it is more preferable that the embedding depth of the light source portion is large so that the lighting equipment is not visible when viewed from the second living room 22 on the second floor. In the exemplary embodiment, a plurality of such luminaires 71 are mounted downward at appropriate intervals, at least one of which illuminates the ground of the courtyard 3 (near the root of the planting) and at least one of which is planted in the courtyard 3. Light is distributed so as to illuminate the branches and leaves of the provided symbol tree 31. By firmly securing the "ground light" that illuminates the ground in this way and raising objects such as the symbol tree 31, which tends to be an accent, it is as natural as moonlight, especially when viewed from the indoor side. An impressive night view is created.

Further, the lighting fixture 72 on the outdoor living space 6 side is attached to a high place on the outer wall of the building 1 close to the outdoor living space 6, specifically, a protruding corner portion near the children's room 28 on the second floor. A spotlight having a wide irradiation range can be preferably used for the luminaire 72. This spotlight is also lit so as to illuminate the entire courtyard 3 from the height close to the eaves 8 on the second floor to the outer wall of the building 1 surrounding the courtyard 3 diagonally downward.

As the light source of the luminaires 71 and 72, it is preferable to irradiate white light having a color temperature corresponding to white to neutral white and a light bulb color. Further, in order to make the planting or the like look beautiful, it is preferable to use a high color rendering property containing a red or green wavelength component. Further, from the viewpoint of power saving, it is also preferable to use a light emitting diode as a light source.

By adopting the space composition around the courtyard 3 and the lighting method as described above, it is unnatural when viewed from the indoor living room 13 or the dining room 14 and when viewed from the outdoor living room space 6. A soft and bright night view with a natural impression will be created without backlighting and the light source not directly entering the eyes.

By the way, at night, if the indoor lighting is too bright, the indoor appearance may be reflected on the window surface, making it difficult to see the outdoor scenery. In addition, the light source of the lighting equipment installed indoors may be reflected on the window surface and look dazzling. In order to avoid these, in the invention disclosed in the present application, for example, as the ceiling light 45 of the living room 13, a downlight embedded in the ceiling surface is adopted. It is more preferable that the downlight is a glowless type in which the amount of irradiation to the side is suppressed. By arranging the downlight as far as possible from the window surface 41, it is possible to prevent the light source of the luminaire from being reflected on the window surface. In addition, the illuminance of the entire room by these lighting fixtures can be adjusted so that the illuminance can be made smaller than the illuminance of the courtyard 3. Further, regarding the lighting to irradiate the courtyard 3, the illuminance and the irradiation angle can be adjusted so that the illuminance of the courtyard 3 can be made larger than the illuminance of the entire room. Due to these considerations, the courtyard 3 can be easily seen from indoors, and the appreciation is further improved.

Further, an irradiated object having a height higher than the line of sight of a person, such as the symbol tree 31 arranged in the courtyard 3, reflects the illumination light over a wide range in the vertical direction, so that it has a presence when viewed through a window. It also has the effect of making the reflection on the window surface less noticeable. The invention disclosed in the present application also improves the appreciation when the courtyard 3 is viewed from indoors.

The technical scope of the invention disclosed in the present application should not be construed in a limited manner by the illustrated embodiment, but should be conceptually interpreted based on the description of the scope of claims. In carrying out the invention disclosed in the present application, the shape, structure, material, quantity, relative positional relationship, etc. of the components not specifically specified in the claims are substantially the same as those in the illustrated form. It can be appropriately modified within the range in which the lighting effect can be obtained.

For example, the form of the courtyard may be one in which the ground is covered with a wood deck, a permeable block, or the like, or an artificial object, a fountain, or the like may be arranged in place of the tree. The plan shape of the courtyard is not limited to a rectangle, and the position and size of the outdoor living space may be appropriately modified according to the scale of the entire building and the shape of the site. Further, the number of lighting fixtures may be increased or decreased accordingly, or the lower surface of the eaves may be selected as the mounting position of the lighting fixtures.

The invention disclosed in the present application can be widely applied to the spatial composition around the exterior of various buildings such as houses.
