Can we do facade lighting like a Professional Designer?
The façade image of the building depends not only on the material and shape of the façade itself, but also on light (including the direction of light) and color. During the day, the direction and intensity of sunlight change with time, and the appearance of the building changes with daylight. At night, when different lighting methods and lighting control combinations are used, the façade of the building presents a different image.
Daylight is admired for its constantly changing nature, and here is an analysis of the north to Mount Rushmore National Memorial, which take on a different image depending on the daylight. The influence of different natural lighting and artificial lighting on the image of buildings is magic.

There are different types of building facade. According to the different types of building facade, we should adopt the lighting method suitable for this kind of facade, in order to better express the aesthetic feeling of the building at night. The following are some outdoor facade lighting tips from some professional lighting designers.
The corresponding analysis is made according to these 7 different facade typesbelow, with some Facade Lighting Tips.

Floodlighting on the solid façade will flatten the facade, and as the facade rises, the brightness of the facade will gradually decrease and a low contrast transition to the dark night sky will occur. The use of floodlighting highlights the surface texture of the facade material. And for those facades that do not have texture, the light that spreads out over the façade forms a light spot that itself forms the important pattern of the Facade.

The facade effect of vertical separation is enhanced by a narrow light projection on the vertically separated facade. To avoid shadows, the luminaire should be properly positioned and the lighting direction should be oriented parallel to the facade.

When project light on the horizontally separated facade, the upward lighting close to the facade will enhance the three-dimensional feeling of the facade. By increasing the distance of the luminaire from the façade, the long and heavy shadow of the raised portion of the façade can be reduced.

Sometimes, LED neon flex or LED strip with aluminum profile include PC cover or LED linear lights can be arranged on the horizontal partition structure of the facade to represent the horizontal partition of the building.

Generally speaking, the different parts of the concave-convex facade can be treated with different illuminance or different light color to enhance the rhythm of the facade appearance. The use of flood light with wide beam angle will reduce the contrast between the bump of the facade, making the building “flat“.
 

When lighting the facade with window or holes, it should be noted that the lighting of the facade does not produce glare to the people indoors. The general use of lighting to highlight the outline of the window or hole will enhance the building’s sense of drama.
 

For the strip-shaped layered façade, by spreading the light from the inside out, it reinforces the building’s presence at night and creates a strong contrast between the lighted windows (interior) and dark façades.

In daylight, the transparent facade of the building is dark and reflects its surroundings. The presence of indoor lighting allows one to see the interior of a building. The upper light on the interior top surface enhances the presence of the roof, making the interior brighter at night, and the framing of the facade creates a silhouette effect. When linear lighting is applied to the top surface of each floor, the horizontal structure of the building is strengthened.

There is no fixed method of lighting different forms of facades. The most important thing is that the lighting designer should master the corresponding effects and advantages and disadvantages of different methods, then make decision according to the overall creative design concept.

3. As shown in the image below, in a building with curved glass walls, strong white light inside each horizontal divider strengthens the horizontal arc of the building, making it look both stable and fluid:


Summary, The building surface is the first impression of the building, which not only reflects the function of the building, but also reflects the distinctive characteristics of the building.
