How to illuminate the facade of the building? Before answering this question, you need to answer another question, which is why it is to be illuminated? There are about three types of building facades: landmark buildings, beautiful scenery, landscapes/views on the main roads, ok, after screening the targets, follow the author's four ways of learning the façade lighting!
1. External light (flooding)
Place a spotlight on the underside of the building. When the facade of the building is lit, it will show the unlit side, and the light and dark will be staggered to restore the light and shadow of the building. Hand-painted: LEGO
The picture shows the sunlight shining through the clouds on the building, which is the image of a typical floodlight. The façade of the entire building has a distribution of light.
But if you don't do well, it's so embarrassing. The angle, height and color temperature of the lights are inconsistent:
2, internal light
It is better to understand that a lantern that plays like a child is a typical internal light transmission. The light source is inside and penetrates the medium to penetrate.
The light is inside the building, through the glass window, it is an illumination method of light transmission inside. The advantage of the inner light transmission is to highlight the building's transparency and structure. Hand-painted: LEGO
In the West Gram Building in New York, the façade lighting of the building has been set in the office space of the outer circle at the beginning of the design to provide a circle of lights for the interior lighting, which is lit up at night. Therefore, it is possible to realize the inner transparent feeling of the whole building at night, which can reflect the structure of the glass curtain wall. Compared with the building on the right, in the setting of the cloth light without the preset illumination, only the space for working overtime at night will be brighter, which is a more natural landscape.
3, hook
It is also better to understand that in the 1990s, a lot of buildings, especially antique buildings, liked the use of hooking lighting techniques. It is to use a light strip or an array of point light sources to light the side of the building to form a hook effect.
Hand-painted: LEGO
The effect of the hook is actually a flat expression. The way to draw is to draw on a piece of paper with a pen, but the pen becomes the side of the building, so it is a flat expression, and the building is very Three-dimensional objects, using a flat language to express the three-dimensional, the effect can be imagined, so be careful.
At present, the most successful case I have ever seen is the Bank of China Tower in Victoria Harbour, Hong Kong. Because of its peculiar and unique architectural style and language, it can make it more successful with hooks and thanks to the cooperation of surrounding buildings.
On the side of Chang'an Street, a relatively failed case, the background is relatively dark, and it feels completely flat. Basically, it is not a building, like a shelf, pulling a few lights and hooking it out.
4. Other expressions
Due to advances in lighting fixtures and technology, changes in lighting practices have become more diverse.
Express the local structure of the building:
Window sill lights, such a small luminaire, can be equipped with relatively long light, which can make the four or three sides of the window sill illuminated.
Hand-painted: LEGO
If the entire facade is such a lattice, the structure can be illuminated by the window sill lamp, so that the entire facade looks very arrayed in form, which is neither internal nor light, but Hook. It is to realize the construction of the night view of the facade of the building by expressing the characteristics of the building, which is suitable for expressing the structure of the building.
Media curtain wall:
Beijing’s Jingya Building, the first huge media facade in China, is actually an old hotel building. By adding a skin, it is equivalent to adding a TV to the skin and then playing the content on the TV. A building facade that can be performed is also a building curtain wall.
The lighting of the facade of the building is usually the same, but is this over? Far from it, there are a few points to note below:
1. In the past two years, with the continuous improvement of lighting technology, the unreasonable lighting of the building facade has appeared more frequently. The application of the LED screen makes the night view of the building facade completely out of control, because the LED itself has a huge lamp, and the cliff-like brightness difference makes it possible for the local inner light to completely stop the cooking, and there is basically no design of the architectural lighting;
2, high reflective rate material construction is greatly affected by the surrounding architectural practices, causing the neighbors to be very noisy and they will not be able to calm down;
3. At the same time, this matter is generally not the responsibility of the lighting designer and architect. When the owner and the owner's promotion department promote the building, if they install a display directly on the facade of the building, It affects the entire building and the surrounding buildings.
In the CBD of Shenzhen downtown area, the application of LED advertising screens makes architectural lighting useless. The sharp contrast of brightness makes the bright moonlight eclipsed.
