There is a "big chess" behind 10,000 lighting lamps. The Asia-Pacific headquarters building of this company in Caohejing Development Zone

"Shanghai has 2,195 buildings with more than 100 million square meters of office area. About 45% of the electricity consumption comes from lighting and sockets, and air conditioning only accounts for 34%." Recently, Signify Asia Pacific was held in Caohejing Development Zone At the District Headquarters Sustainable Development Seminar, experts and practitioners from different fields such as lighting companies, climate organizations, and the International WELL Building Research Institute conducted in-depth discussions around the low-carbon transformation of the construction field.

Signify's lighting products originate from Philips, an established lighting manufacturer. The company officially launched the Chinese name "Signify" in 2018. It currently has approximately 32,000 employees in more than 70 countries and regions around the world, and its sales in 2023 will reach 6.7 billion euros. The company's Asia-Pacific headquarters is located in the science and technology oasis of Caohejing Development Zone. It is currently accelerating the deployment of intelligent interconnected lighting ecology, smart city construction, low-carbon lighting transformation and other fields.

"When transforming the energy mix, interventions such as the use of renewable energy take a long time to take effect; while the use of energy-saving technologies is expected to more quickly alleviate many of the energy challenges currently faced by people, including electricity and fuel shortages and rising prices." Yao Mengming, General Manager of the Lighting Design and Application Department of Signify Greater China, introduced that the white paper "Intelligent Connected Lighting Empowers Buildings to Save Energy and Reduce Carbon" recently jointly released by enterprises and climate organizations mentioned that currently, inefficient buildings account for 10% of the total worldwide. The ratio reaches 75%, and 80% of the buildings will continue to be used after 2050. Upgrading the lighting system is one of the fastest and least disruptive ways to renovate a building.

Yao Mengming said that statistics show that most people spend about 90% of their lives in various types of buildings, which is why the sustainable development of buildings is crucial to the development of human economy and society.

According to the "2022 Shanghai Energy Consumption Monitoring and Analysis Report on State Office Buildings and Large Public Buildings" jointly released by the Shanghai Municipal Housing and Urban-Rural Development Commission and the Municipal Development and Reform Commission in August 2023, by the end of 2022, Shanghai has completed the data networking of the energy consumption monitoring platform. The total office area of ​​2,195 public buildings exceeds 100 million square meters. The annual electricity consumption of these venues is divided into four aspects: "lighting and sockets", "air conditioning", "power" and "others". The energy consumption of lighting and sockets exceeds the traditional concept of air conditioning energy consumption. proportion, ranking first.

The balance between building insulation and energy-saving lighting has become a breakthrough in the intelligent lighting industry. "If architectural lighting needs to use natural lighting, then when sunlight comes in, the heat will naturally increase, and the indoor temperature will rise accordingly. Air conditioning needs to be turned on to balance the indoor temperature." In Yao Mengming's view, the balance between air conditioning and lighting is Like interdisciplinary issues in architecture. Only through technological innovation can the "contradiction" between the two be effectively resolved.

He introduced that at present, through LED lighting and other related technologies, more than 50% energy saving goals can be achieved compared with traditional light sources. For example, the ultra-high luminous efficiency LED bulbs currently on the market can replace traditional 60-watt incandescent lamps with 4-watt bulbs or the first-generation 10-watt energy-saving LED bulbs produced in 2016. In the Signify Asia-Pacific headquarters building located in the technology oasis of Caohejing Development Zone, more than 10,000 lighting lamps in the building are all connected to the Internet and can be controlled through the PC backend and mobile phone terminals. Intelligent lighting technology is used to integrate the building's energy The consumption is reduced to 70%-80% or even lower than the original.

According to Wu Zhengrui, Vice President of the International WELL Building Research Institute in China, when considering comprehensive considerations for buildings, how to balance the demands of energy consumption, low carbon and human habitation health is particularly important. “People’s health and well-being cannot be sacrificed to meet low-carbon goals…Although not turning on the lights can save energy, we should start from creating an efficient, comfortable and healthy living and working environment to achieve the goals of reducing energy consumption and reducing carbon emissions. "

He suggested that various entities such as enterprises, developers, and construction units should find a "common denominator" between carbon reduction and human health and comfort, and improve the "greenness" of the entire construction industry from the perspectives of optimizing technology and raw materials. threshold". At present, some companies, including Signify, have started to innovate in the field of spectrum, exploring how to achieve the same visual lighting requirements with half the energy consumption.

Wei Jia, head of energy and industrial systems for the Climate Group China, mentioned the concept of "embodied carbon", that is, the steel bars, cement, concrete and other building materials used in the construction process will also produce carbon emissions during the production process. Therefore, Energy consumption needs to be controlled both during the construction and operation phase of the building and during the previous "embodied carbon" phase.

"Data shows that China has nearly 40 billion square meters of existing buildings, of which less than 10% may be energy-saving buildings, and the remaining 90% have the potential to undergo further green transformation." Yao Mengming said that in the face of this With a huge market, the lighting industry has the responsibility and ability to be at the forefront, starting from "light" to optimize energy use in building spaces, and contribute corporate strength to China's "double carbon" goal.
