The greatest thing about Apple is that it has changed the public's aesthetics with design. Both its product design and store design are popular, thanks to the "Minimalism" of Apple's godfather jobs. Jobs personally advocates "minimalism and blank space", which has been well demonstrated in his house:


▲ jobs' home is absolutely minimalist


Today, I want to introduce to you the apple store, which won the IALD Excellence Award in early May. Located on Michigan Avenue in Chicago, it is known as the "lantern on the Chicago River".


Lanterns on the Chicago River -- Analysis of lighting design
Located at the intersection of the Chicago River and the "Magnificent Mile" of North Michigan Avenue, apple Michigan Avenue slopes from pioneer square to the edge of the river, establishing a new connection between the city and the river.

Its idea is to create a soft and warm atmosphere, just like a living room, where people can see, learn and share Apple's innovative products, and create with it. Through the transparent glass wall, we can see that these principles are embodied, and the glass wall dissolves in the soft light line. The soft light will not make pedestrians feel dazzling and can see the road conditions clearly.
In response to this requirement, this building has a great feature in lighting, that is, it balances the light of all floors and wood ceiling surfaces. Through the glass, there is no glare. At night, this building is like a soft lantern, providing tourists with a new public space along the river in Chicago.

 
Most of the lamps on the ceiling are unified recessed downlights. In order to adapt to the extremely thin carbon fiber roof design, these lamps have undergone complex performance design: in order to meet the requirements of high output but thin lamp body, more than a dozen optical devices are used. It can be seen that the function of lamps and lanterns has great flexibility.

In the design process of this project, the physical performance of light is discussed in depth. The lighting team analyzed the relative success of various design options in many performance parameters, including realistic simulations of human perception and experience.

One of the biggest technical challenges is to explore how the incident sunlight can be mixed with indoor artificial light in different locations of the project. By using a physics based rendering engine and viewing the results on the HDR monitor, the team can accurately judge the created atmosphere and ensure similar representativeness of the development design.

An array of four sensors for continuous measurement of daylight channels maintains the mixture of carefully calibrated cold light and warm indoor light, while reducing the total energy consumption of artificial lighting.


 This 32 foot high ceiling provides a panoramic view of downtown Chicago, with trees as the frame, filtering in sunlight, helping indoor lighting create a warm, more intimate space to interact with products. The wooden material is evenly illuminated, strengthening the seemingly impossible slender carbon fiber roof above. The precise balance of perceived brightness of wood and granite finishes on both sides of the glass makes the facade disappear, thus forming a seamless floor and ceiling dotted with mottled shadows. The use of light makes the static wood add dynamic shadow. The combination of dynamic and static makes it more interesting to watch.

Another core goal of the project is to protect the health of employees and the public. The lighting design team chose an LED driver that can minimize glare and stroboscopic light during deep dimming and long-time exposure to avoid eye fatigue, headache and fatigue. In the evening, the lighting of the project darkens, showing a warmer color temperature, which is designed to be consistent with the light color of natural sunlight and avoid a negative impact on the circadian rhythm of employees.

The lighting designer participated in the whole project, learned every updated detail in the meeting with the owner, and gave a supporting concept to achieve the architect's goal. The result is a very transparent facade, which can pass through the building from all angles to enjoy the night scene.
