Architectural appearance game: building energy conservation, beauty and energy conservation simultaneously?

The following is the related content of architectural appearance game, building energy saving, aesthetics and energy saving brought by Zhong Da Consulting for your reference.

Once upon a time, skyscrapers replaced old low-rise bungalows, and tiles and glass smiled and sent away red bricks and gray tiles. Have you found that the novelty, novelty and uniqueness of architectural modeling have become the true meaning worshipped by developers and designers, and also become a tool to attract consumers' attention and purchase rate? However, with the country's increasing concern about building energy efficiency, many buildings famous for their artistic beauty have evolved into high-energy consumption targets. Question: Is there any contradiction between architectural art and energy saving? Who is responsible for deciding whether they are hostile or harmonious? ...

Contradictions vary. Glass curtain wall, love it, love it.

With the development of modern architectural technology, the gorgeous degree of architectural modeling and appearance is changing with each passing day, and the appearance of glass curtain wall architecture is an example. According to incomplete statistics, the existing glass curtain wall area in China has exceeded 9 million square meters, and it is constantly developing and has become a symbol of modern architecture. However, the ensuing energy-saving contradiction can not be ignored. Due to the extensive use of glass curtain walls, strong ultraviolet radiation in summer and cold in winter, most skyscrapers have to increase their power to turn on air conditioners and adjust the room temperature ... The high energy consumption is shocking.

In this regard, Wang of Beijing Xinliji Vacuum Glass Technology Co., Ltd. has personal experience in practical work contact. "Most developers and designers follow suit, overemphasizing the visual effect of building appearance, but ignoring the requirements of energy saving. For example, the glass curtain wall, the buildings used earlier in Beijing are mostly single-layer glass, which is a model of high energy consumption. " According to Wang, she once came into contact with a client in Taiwan Province at work. Because she fell in love with the appearance of the ideal office building at first sight, she rented a whole floor as an office space without thinking, and put her office in the southwest corner with the best environmental sight. Because the glass is too transparent, the boss keeps in close contact with Grandpa Sun at nine o'clock every morning until the sun goes down. The outdoor spring breeze attacks people, and the indoor sun is like summer sun, even if the air conditioner is on, it will not help. When the developer and the property were asked to refit the glass sunshade, the boss of Taiwan Province Province had to move with all the employees of the company.

"There are two kinds of heat transfer of curtain wall glass, one is convection and conduction heat transfer caused by temperature difference, and the other is direct sunlight caused by solar radiation." Wang told reporters, "At present, the vast majority of buildings with single-layer glass curtain walls are real gold treasures. They' reject' the heat brought by solar radiation in summer, and they can't keep warm in winter, so they are considered to be the answer to failure in terms of energy saving and indoor comfort. "

Beauty and energy saving do not conflict.

Is it wrong to use glass curtain walls on a large scale in buildings? Is it irreconcilable with the conservation of energy?

"Architecture is an art, energy conservation is a national policy, and art and energy conservation can be completely unified in architecture." Fang Chao, chairman of Guohua Real Estate Development Co., Ltd. believes that there is no contradiction between architectural appearance and energy saving. For example, the controversial glass curtain wall is reasonable in use. The current architectural design concept is that people and the environment are born and integrated. Only by keeping people in a dark room and relying on artificial lighting does it not meet people's work and life needs. Therefore, good landscape and lighting in the office have become the pursuit of people. However, it is unrealistic to overemphasize the appearance of the building and sneer at energy saving, or to let the building return to the plastic shed era for energy saving. It is necessary to find a "balance point" between building appearance and energy saving, so that the glass curtain wall can meet people's use functions such as "landscape and lighting" and rely on modern scientific and technological means to meet the requirements of building energy saving.

"Glass curtain wall is also a technology, and the energy-saving problem it brings can be solved through scientific and technological progress." Speaking of this, Fang Chao illustrated that the office building of ITC also uses glass curtain wall technology, but its energy-saving coefficient must meet the most advanced technical standards at home and abroad. Therefore, KPF design company has done a lot of research when choosing glass curtain wall, including reflectivity, transmittance and light pollution ratio of coated glass, and found the corresponding balance point. Inert gas in double-layer Low-E glass is used to reduce heat transfer coefficient, radiation heat and heat conduction, and ensure heat insulation.

Wang also gave a negative answer to the question of whether energy saving and aesthetics are contradictory. "Beauty and energy saving are not contradictory. The key lies in the understanding of developers and the application of new technologies. For example, the energy-saving technology of glass is changing with each passing day, and Low-E, hollow and vacuum glass emerge one after another. Buildings can be beautiful and energy-efficient. "

Who says contradictions don't exist?

Some people may ask: If there is no contradiction between architectural appearance and energy saving, why are there high-energy-consuming buildings such as Xihuan Square and Jianwai SOHO?

"Architectural art and energy saving are not zero contradictions." Qu Ruifu, general manager of Poly Group New Poly Building Real Estate Development Co., Ltd. told reporters: "There is a popular saying in the construction industry: waste is beauty. Under the guidance of this idea, many special-shaped buildings are beautiful but not energy-saving. It should be said that energy saving is inseparable from the facade of the building. For buildings with the same volume, the larger the external area, the greater the shape coefficient and the worse the energy-saving effect. For example, many buildings in Beijing are' gegewu', with large heat dissipation coefficient and weak energy saving. "

In terms of energy saving and building comfort, Qu Ruifu believes that there are also contradictions. "It can be said that high-standard buildings pay more attention to comfort, and the contradiction with energy conservation is more prominent. Not all office workers enjoy the room temperature of 26℃, and the energy consumption is bound to be different. Therefore, different levels of architecture should be analyzed in detail. For a public building like a theater, the room temperature of its performance hall cannot be required to be 26℃. Because it is a crowded space in a short time, it is particularly important to keep its air clean and the temperature required by the audience and performers. Therefore, building energy conservation should not be a metaphysical slogan, and different buildings should be treated differently under the premise of meeting the national unified energy conservation standards. "

Regarding the contradiction between building energy saving and appearance and comfort, Gu Yunchang, vice president and secretary general of China Real Estate Association, said: "There is indeed a contradiction between high comfort and energy saving. The average energy consumption of heating in winter in China is 16 liter, while that in developed countries is only 6 liters or even 3 liters. Because of their good thermal insulation performance, they are both comfortable and energy-saving. In China, most of the energy is radiated by gorgeous walls and beautiful glass. How to solve it? The green building advocated at present is a good experience, and we should make more fuss about architecture to reduce energy consumption. "

"Energy conservation is the foundation." Qu Ruifu firmly said that because architecture is an art, there is nothing wrong with beautiful appearance. If architecture is to be used by people, humanization is more important. The key to human survival on the earth lies in all kinds of energy, which is the foundation. If energy is exhausted, there will be no survival, let alone art. Therefore, we should stand on the shoulders of giants, not dwarfs, and pay attention to building energy conservation.

Who decides whether to save energy or not?

From the embryo to the formation of a building, can "energy-saving nutrients" be infiltrated into its planning and design? Who will control it and where will the hand of control come from?

Designer's hand

"Designers pay more attention to energy saving. Some developers have not considered the details of energy saving, and the designers have already implemented it on the drawings. " Qu Ruifu told reporters that developers are attracted by well-known design companies because they hope that designers with professional vision can apply their advanced concepts of energy saving, environmental protection and green, as well as specific technical measures to construction projects.

I believe that in the eyes of most people, a building reflects the designer's ideas from the appearance to the internal framework, so it is particularly important to control the "designer's hand" of the building. Therefore, many developers have hired well-known design companies at home and abroad, such as China Trade Center and KBF Design Company, New Poly Building and SOM Design Company to join hands.

"The process of choosing an architect is the process of choosing high technology." Fang Chao believes that building technology and energy saving depend on designers to a great extent. "Designers are professionals in the construction industry. They pay more attention to the application of scientific and technological materials and technology in the real estate field than the general group. At the same time, they have a unique vision for the reference of advanced design technology and equipment. "

The hands of developers

If the designer is directly interested in architectural modeling and energy saving, how long is the developer's hand and how effective is it? Wang said that developers have more power than designers. In the process of promoting related technologies and energy-saving products, design units are often more willing to adopt new building materials and energy-saving and environmental protection products, but when they reach the hands of developers, they get stuck and encounter greater resistance.

Regarding the relationship between developers and designers, Qu Ruifu looks at it this way: some famous design masters are full of personality and often do something unconventional according to their own preferences and styles. Most of their representative buildings are flashy and ignore energy saving, which leads to a sharp increase in the future operating costs of developers and owners. Therefore, the developer who pays the money has the right to control the designer and let his works develop in a direction that is beneficial to the developer and the owner. It can be said that whether a building is both beautiful and energy-saving is closely related to the owner of the project itself-the developer. The identity difference of developers as sellers or operators greatly affects the number of energy-saving measures of buildings.

The hand of the government

When we talk about building energy efficiency, no one will ignore the attitude and measures of the government. A few days ago, relevant laws and regulations such as "Design Standard for Energy Efficiency of Public Buildings" and "Notice on Strictly Implementing Design Standard for Energy Efficiency of Newly Built Residential Buildings" were promulgated one after another. It is understood that the Beijing Municipal Construction Committee recently launched a "survey on the quality of existing glass curtain walls". For building energy conservation, the government can be said to be "lucky".

"In the early stage of economic development, a country will inevitably have some short-term benefits. With the progress of development, the disadvantages of short-term interests will gradually emerge, and the emerging cases will teach people to pay attention to environmental protection, energy conservation and green. " For this reason, Qu Ruifu fully agrees with the government's measures to drastically reduce energy-inefficient buildings. "The purpose of sanctions is to make developers' ideas, behaviors, starting points and destinations focus on the overall situation, law and energy conservation. In addition to sanctions, the government should not ignore the hand of publicity and encouragement, thus prompting more developers to change from' unconscious' to' spontaneous' energy saving. "

Consumer's hand

According to most people's understanding, consumers are still vulnerable groups, with little right to speak and weak control over building energy conservation. Actually, it is not. Qu Ruifu said frankly, "Consumers can completely control developers. It is precisely because there are many developers who are eager for quick success and instant benefit in society. What they fear most is that their products are not favored by consumers and are not accepted by the market. Therefore, as long as consumers and buyers have a deep understanding and clear standards for building energy efficiency, buildings that are not energy-efficient and their developers will eventually be eliminated by' competitive consumers'. "

Fang Chao pointed out that it is beyond the control of a certain social group to make the future buildings harmonious in appearance and energy saving. It needs the joint efforts of the government, design units, developers and the public to make energy conservation a driving force.

"Only when consumers truly understand the benefits of energy-efficient buildings to themselves and make clear the long-term accounts of energy conservation can their enthusiasm for active participation be rapidly improved." Wang believes that the account of energy-saving money cannot be calculated by consumers themselves, and the government, media and developers all have the responsibility and obligation to guide consumers. Only in this way can the road of building energy conservation development in China be more open.
