　　Recently, some readers reported to this newspaper that some glass curtain walls of the World Financial Center reflect strong light. Not long ago, the planned Shanghai Tower, the tallest building in China, published an environmental assessment report online, in which "the influence of reflected light from glass curtain wall" attracted people’s attention.

　　The glass curtain wall causes strong light reflection and causes light pollution, which has become a problem that cannot be ignored in urban development. Is it a light and beautiful building material "angel" or a "devil" that causes light pollution?

　　The reporter recently visited the main argumentation and examination and approval department of "light reflection influence".

　　The inner ring line was once banned, but the effect was not obvious.

　　In the Building Energy Conservation Section of the Shanghai Construction Industry Management Office and the Office of the Science and Technology Committee of the Shanghai Municipal Construction and Transportation Commission, two responsible persons mentioned one thing in unison-in 1999, the Standing Committee of the Municipal People’s Congress promulgated the Regulations on the Management of Construction Engineering Materials in Shanghai, which stipulated that the Municipal Commission for the Establishment of Diplomatic Relations should compile a "prohibited and restricted catalogue" and publish it after approval by the municipal government.

　　In 2000, the first batch of "Prohibited and Restricted Catalogue" was published, and the glass curtain wall was among them. At that time, it was clearly stipulated: "It is forbidden to design and use glass curtain walls within the inner ring road, except for the podium of the building; Between the inner ring line and the outer ring line, the area of glass curtain wall shall not exceed 40% of the construction area of the outer wall. Construction projects using glass curtain walls should be implemented after environmental assessment by the environmental protection management department and approval by the planning and construction management departments. "

　　However, the development of glass curtain wall has not stopped because of the publication of the catalogue. Wu En, deputy director of the Office of the Science and Technology Committee of the Municipal Commission for the Establishment of Diplomatic Relations, explained: "Before the publication of the catalogue, many construction projects have passed the examination and approval. This legitimate reason makes these projects exempt from the catalogue."

　　At present, there are many glass curtain wall buildings on both sides of the road, many of which were built after 2001 and are within the inner ring. It is forbidden to stop, ostensibly because of the "time difference" of project approval, but in fact it has a compelling reason.

　　What materials can be used for high-rise buildings without glass curtain walls?

　　An expert from Shanghai Environmental Monitoring Center, who asked not to be named, believes that the widespread use of glass curtain walls is mainly aimed at the "helpless actions" of the city’s super high-rise buildings. This expert has participated in the examination and approval of many important construction projects in the city. She said that although the regulations on restrictions on the use of glass curtain walls have been issued for many years, it is "unrealistic" to completely ban them. Mr. Shen, the head of the Building Energy Conservation Section of the Shanghai Construction Industry Management Office, said: "The’ one size fits all’ approach is not appropriate."

　　"The glass curtain wall is really necessary, and some of its advantages are irreplaceable by other building materials." Wu En explained that especially for super-high-rise buildings with more than forty or fifty stories, the load-bearing requirements for the foundation are relatively high. Under the same circumstances, light glass curtain walls have to be used as the external wall. "If a building with a height of one or two hundred meters does not use glass curtain walls, what better materials can it use?"

　　In addition to being light, the glass curtain wall also has the advantages of beauty, earthquake resistance, high permeability and rapid construction. Since the early 1970s, Shanghai has tried to integrate it into urban architecture for the first time. It has been more than 30 years since then, and its technology has passed the standard and its safety factor is high, which naturally makes it the first choice for many architects and developers.

　　Light pollution is difficult to avoid, but it must be strictly controlled.

　　Glass curtain wall is sometimes a "double-edged sword". On the one hand, glass can be recycled, which makes it stand out from many light materials such as aluminum; On the other hand, strong light reflection causes pollution, which attracts more and more attention.

　　"Admit its necessity, and we can’t ignore the negative effects." Wu En introduced that the municipal environmental protection department has issued regulations that when glass building materials are used for building exterior walls, glass with low reflectivity should be used, and the visible light reflectivity should not exceed 15%.

　　"The implementation of the regulations is good, but the 15% standard cannot solve the fundamental problem." Yuan Bo, an expert from the Science and Technology Committee of the Municipal Commission for the Establishment of Diplomatic Relations, explained that even if the reflectivity is reduced by half, it will still cause strong light reflection to some extent. "Technically, the ideal reflectivity can be controlled to 3%, but this kind of glass costs three or four thousand yuan per square meter, which is several times that of ordinary glass."

　　"When the light is sufficient, the glass curtain wall partially reflects a small amount of strong light, which is difficult to avoid. This is not terrible. The key is that it cannot be reflected to nearby residents’ homes and affect their lives. " Wu En introduced that this is what the Science and Technology Committee focused on.

　　The demonstration is generally divided into two steps: first, draw detailed drawings according to the surrounding conditions of the building, and then analyze the various angles that the glass curtain wall may reflect light, and whether it will affect residents. "When the building is built, it will definitely be too late, and it must be involved when reviewing the construction sketch. If it is not up to standard, the drawing review will not pass. "

　　"As long as light pollution is found during the demonstration, even if it only affects one or two residents, we will never let it go and must solve it in time." Wu En explained, "There are two commonly used remedies: adding a light shield on the outer wall to reduce continuous total reflection; Stick a film on the glass surface to reduce glare. In the event of a dispute caused by light pollution, it is generally negotiated by both parties, with economic compensation as the mainstay. At present, there is no clear mediation method and compensation provisions. "

　　In order to allow the majority of netizens to keep abreast of the dynamics of new cars at any time, Aika Automobile will review last week’s key new cars every Monday. Today we want to review the key new cars of last week (July 19-July 25), including the popular model City Edition, as well as the leapfrog compact SUV with a wheelbase of 2845mm. In addition, with the same origin, the easiest entry-level sports car, the new generation BRZ, also opened the blind order last week. Well, without further ado, let’s follow our article to review those unforgettable moments in the car market last week.

　　Model: Tank 300 City Edition

　　Price range: 20.00-23 0 yuan

　　Review:In today’s society, Internet celebrities not only appear in the entertainment industry, but also in the automotive industry. The Tank 300, which went on sale in December last year, is one of them. From the sales data, the Tank 300 has achieved very good sales in half a year, with a cumulative sales volume of 33,073 units. The strong popularity has led to a long wait for delivery due to production capacity problems after being listed for half a year. As a new model, the Tank 300 City Edition naturally attracted countless attention at the beginning of its birth, and unlike the current model, the overall design of the Tank 300 City Edition is more youthful and fashionable. Through changes in appearance details and color schemes, the Tank 300 City Edition retains its tough nature while bringing consumers more youthful and fashionable elements to meet the needs of young off-road consumer groups.

　　On July 23rd, the Tank 300 City Edition was officially launched. Although it was a new special edition, the official launch of the Tank 300 City Edition was a relatively rich three models. The names of the models are also very interesting, called "very stylish", "I see the type", "must type", and the price range is 20.00-23 0 yuan. However, it should be noted that the "must type" of the three vehicles is sold in a limited form every month. On July 24th, the first limited edition of 300 units will be launched at 0 o’clock. After that, the monthly limited number will be announced on the Tank TANK APP in advance, and it will be sold on time at 10 am on the 19th of each month until the order is completed.

　　In terms of overall design, the shape of the Tank 300 City Edition is the same as that of the ordinary version, but it is different in some details. First of all, the Tank 300 City Edition has added two body colors, which are officially called face powder and grass green. Obviously, these two color schemes are more likely to attract the attention of young consumer groups. In addition, the front grille of the Tank 300 City Edition has changed from the black of the ordinary version to silver, as well as the wheel eyebrows. These changes make the Tank 300 City Edition more fashionable in the nature of the tough guy. The body size has not changed, and the length, width and height are still 4760 × 1930 × 1927mm, and the wheelbase is 2750mm.

　　In terms of interior, the Tank 300 City Edition is basically the same as the ordinary version. The changes are the same as the appearance, and it also appears in the color scheme. The Tank 300 City Edition also adds two exclusive color schemes: "face powder" and "grass green". In terms of power, the Tank 300 City Edition is still the familiar 2.0T engine, and the transmission is still 8AT. However, it should be noted that the Tank 300 City Edition is equipped with intelligent four-wheel drive TOD (two-speed), and the front and rear axle electronically controlled differential locks are cancelled.

　　Model: Geely Xingyue L

　　Price: 13.72-18 5,200 yuan

　　Review:Geely? Geely Xingyue L? According to common sense, Xingyue L seems to be an extended version of Xingyue, but is it really the case? In fact, the addition of L to the back of most models does symbolize lengthening, but its changes are limited to lengthening. In addition to the overall size of the Xingyue L, there are many differences. First of all, Xingyue is a coupe SUV, but Xingyue L is a traditional SUV shape. Secondly, the size of Xingyue L has surpassed Xingyue in an all-round way. Although the positioning is compact SUV, the 2845mm wheelbase makes it larger than many medium-sized SUVs. In terms of interior, Xingyue L has also overturned Geely’s previous models, and the three 12.3-inch large screens are the finishing touch. And high-end configurations such as G-AVP 1km unmanned parking technology and global FOTA online upgrade technology also prove that this car is not just an extended version of Xingyue.

　　Let’s review the Geely Xingyue L model. On July 20, 2021, Geely Xingyue L was listed in Hangzhou, and the price range of 6 cars was 13.72-18 5,200 yuan. At the listing press conference, Li Shufu, chairperson of Geely Holding Group, who rarely appeared at the new car launch of various brands, was a rare platform, which proved the importance of Geely officials to Xingyue L. It is definitely a subversive model for Geely. Just like a few years ago, Xingyue L is a milestone model representing Geely’s brand entering the "Geely 4.0 era of technology".

　　The design of the Geely Xingyue L continues the design language of the Geely 4.0 era. Unlike the coupe SUV Xingyue, the Xingyue L shows us the aura of a traditional high-end luxury SUV. Unlike the front face of Xingyue, the Xingyue L adopts a more atmospheric straight waterfall grille. The energy matrix headlights of the double-stage design use a full LED light source, which is combined with the through-chrome trim on the lower part of the front face to stretch the visual width of the front face.

　　From the side, the Xingyue L adopts a traditional SUV shape that is different from Xingyue, and the muscular body lines tell you that it is not a restrained "boy" that is easy to bully. At the same time, we must focus on the body size of Xingyue L, length/width/height 4770 * 1895 * 1689mm, wheelbase 2845mm, remember, the official positioning of Xingyue L as a compact SUV, but this body is obviously beyond many medium-sized SUVs, this is a proper leapfrog suppression method! As for the tail, Xingyue L wears the current popular through taillights on the body, and there are no less trendy elements.

　　The interior of Xingyue L is also one of its subversive designs. Although everyone doesn’t feel much when looking at the pictures, its interior panels do use a lot of suede fabrics, and with exquisite stitches, the high-end feeling suddenly bursts out. However, what attracts me the most is the three 12.3-inch large screens that cannot be ignored. Qualcomm Snapdragon 8155 chip escorts its operation, and there are many functions such as Douyin, Karaoke, games, and watching videos. There is also a high-tech that has to be said, that is 5G-AVP 1km unmanned parking technology. Xingyue L is the first model equipped with this technology, which can achieve unmanned parking within 1 kilometer. Novices don’t have to worry about parking difficulties anymore, just use their mobile phones.

　　In terms of power, Xingyue L brought over the Drive-E series 2.0TD engine, and also provided two versions of medium and high power, with a maximum power of 160kW (218 horsepower) and 175kW (238 horsepower) respectively. Reflected in terms of performance, the 2.0TD engine gives Xingyue L the strength to break 100 in 7.7 seconds.
