Worldwide City Lighting Report in Copenhagen / Stockholm December 2-9, 2017　|　Written by: Hu Lin and Simeng Huang Located in high latitudes on the Northern Hemisphere, northern European countries including Norway, Sweden, Finland, and Denmark are known to be very unique in terms of the seasonal natural phenomena – the midnight sun during the summer, and the polar night during winter. In this December, we went to some of the cities experiencing the polar night during winter to research lighting environment. Considering extremely long night hours can affect circadian rhythm, are city lighting and residential lighting in those countries designed to eliminate the problem? In this trip we closely looked at the light environment that are unique to Northern Europe, gained through observation of public facilities and residential lighting. Here is the research results. Christiansborg Palace Pole lamps at bicycle parking outside the Danish Parliament Catenary lighting illuminating the roadway ■Copenhagen, Denmark In Copenhagen, the capital of Denmark, classic design and contemporary design co-exist, each divides the city into visually distinctive areas. An area across a canal is on a new development with various kinds of new buildings are being constructed. If you walk in this city, you will feel the history of Copenhagen and be convinced how this city takes creative culture so important. ■Classical Lighting Copenhagen is a city where you can feel its history reflected upon the classical architectural design and how they use light. The city is…

City Night Survey : Saitama-Shintoshin 2019.04.11　　Lin Hu + Hikaru Kimura Saitama Shintoshin is a district established around the year 2000. Centered on JR Saitama-Shintoshin Station, it is an intensively structured urban area featuring a variety of functions, including large-scale commercial facilities, a major multi-purpose arena, government office complexes, and hospitals. This survey examined how this planned city has evolved from the perspective of lighting. Nightscape over the heliport from the Saitama Government Office Complex Light Linking Spaces A pedestrian walkway system is installed around Saitama-Shintoshin Station, utilizing an active pedestrian-vehicle separation plan that allows for smooth circulation from the second-floor station gates to various facilities. While the ground level is brightly illuminated by roadway pole lights, the pedestrian walkways feature lower-level lighting such as uplights and footlights—excluding some decorative pole lights in park areas—creating distinct expressions of light for each zone.Saitama-Shintoshin Station is connected to Kita-Yono Station by a walkway spanning approximately 600m. A continuous cantilevered glass canopy allows pedestrians to walk without getting wet in the rain or being stopped by traffic signals. Along this route, there is a straight path of about 100m running parallel to the railway tracks. Here, despite the cantilevered canopy structures being identical—likely due to differing construction phases—the lighting techniques varied across three distinct types. Although the architectural design is similar, the change in lighting methods results in varying levels of brightness depending on the location. While achieving uniformity may seem important, using different…

Tianjin is situated 150km east of Beijing and easily reached in a 30-minute high-speed train ride. Historically, foreign influence including the UK and Germany has shaped the western-style architecture and streetscape that this city is famed. Tianjin also poses the largest harbor in Northern China, a gateway for this economical and technical development zone. Upon exiting the main station, a panoramic view of the city awaits. The western architecture, remnants from the foreign settlements era, is illuminated in low-color temperature light and stands in contrast to the newly constructed skyscrapers. A historical western architectural structure is now used as a banking facility. At night, orange-colored fluorescent and high-pressure sodium lamps softly illuminate the facade. Downtown is also bustling with construction. During the day the area is swarming with shoppers and construction site workers. At night, mega size digital media, neon signage, and colorful lanterns are everywhere, with even more foreseeable in the future as the construction boom continues.

The largest Chinatown in Japan has become an established feature of the Yokohama downtown area, but still an area with its own culture and identity. We surveyed Yokohama to discover the Chinese style of lighting environment alive within Japan. At night, there are many hanging lanterns with soft glowing light. This “Light with a Shape” or, through colorful shades, “Light with Color” is a staple of Chinatown and helps to create excitement and a sense of elation. Along the main street there is no specific street lighting, but shop lighting and luminous signage create a natural ambiance along the street. Most structures have columns painted red and use warm tone lighting, but the facade design and signage is all different. This unification of the streetscape through color temperature creates a balance and lasting impression of Chinatown.

2018/10/13-23 Mikine Yamamoto + Kouki Iwanaga This was our first South American survey in about 15 years. We tracked the light expression of Rio de Janeiro, a port city marked by both entertainment and poverty, which hosted the FIFA World Cup in 2014 and the Olympics in 2016 and has become increasingly international. While possessing famous coasts like Copacabana and Ipanema and being counted as one of the world’s three most beautiful harbors, it also has the “favela” slums covering its hillsides. Surrounded by magnificent nature, Santiago, Chile’s largest city, has annual rainfall of only about 360mm, meaning it is sunny for most of the year. We investigated the lighting situation of this city blessed with natural light.

It is said to be a microcosm of the country, where light and darkness coexist: scenic areas with beautiful topography blending nature and culture are situated next to slums. We surveyed the light expressions of this city, which has various faces, including the glamorous light of tourist and resort areas, and the strangely glowing light of the favelas (slums) where poor communities gather, reflecting the lives of the people.The suburbs leading from the…
