A brief analysis of the specific contents of green, environmentally friendly and energy-saving industrial buildings. The following Zhongda Consulting and Bidding Teachers will give you answers for your reference.

1 Foreword

Green building refers to maximizing resource conservation (energy saving, land saving, water saving, material saving), environmental protection and reduction during the whole life cycle of the building. To eliminate pollution, provide people with a healthy, practical and efficient use space, and create buildings that are in harmony with nature. Therefore, integrating the concept of sustainable development into the entire life cycle of a building, that is, developing green buildings, has become an inevitable trend in the development of construction technology in the future. In August 2010, the Ministry of Housing and Urban-Rural Development issued the "Green Industrial Building Evaluation Guidelines", marking the further extension of China's green buildings from civil buildings to the industrial building field.

2 Green energy-saving industrial building design

The huge driving force and source that promotes the rapid development of society is industrial civilization. As a type of building that directly serves industrial production, industrial buildings have made important contributions to promoting the development of industrial production. The essence of modernist architectural thought is to express the value orientation of industrialization in architectural vocabulary. It is undeniable that industrial buildings are often places that generate noise, air pollution, and water pollution. In turn, environmental pollution not only seriously shortens the service life of industrial buildings, but also poses a threat to human physical and mental health. Currently, in the context of sustainable development, the field of industrial construction should also introduce green building concepts, pay attention to and improve them in design, and reflect greenness and environmental protection.

2?1 Creation of the overall image of green industrial buildings

With the development and progress of science and technology, modern industrial buildings are becoming increasingly large, with industrial plants often covering hundreds of thousands or even hundreds of thousands of square meters. The scale not only brings convenience to production, but also requires the support of more modern technologies. There are contradictions in multiple functions in this large space. A wide variety of equipment, conveyor belts and various power pipelines pose complex challenges to the building. Require. At the same time, the huge modern industrial buildings also mean an impact on the environment. The sound, light, heat and various emissions generated by production activities and even the industrial buildings themselves have a great impact on the local environment. To reduce the negative impact on the environment and create an overall image of green industrial buildings, we must respect and protect nature, effectively use water and various natural resources, and minimize the consumption of energy and resources; try to maintain the ecological balance of the surrounding environment of the building and comprehensively Consider the regional environment of the building and adapt measures to local conditions. Therefore, the creation of the overall image of green industrial buildings should start from two aspects: focusing on site selection and optimizing layout structure.

2?1?1 Pay attention to site selection

The site selection of green industrial buildings should be selected in a reasonable location to reduce damage to the environment and ensure the continuity of the basic functions of the urban natural ecosystem. safety and integrity, ensuring the safety and health of the city, and ensuring ecological security. In addition to the commonly considered building site selection factors, the following principles should also be paid attention to: 1) Ecologically sensitive areas should be avoided, such as forests, water bodies, nature reserves, etc.; 2) The ecosystem of the site should be protected, and the topography, landforms, vegetation and natural water systems, maintain the continuity of history, culture and landscape, maintain the ecological integrity and biodiversity of the site, and control various pollution emissions that may occur; 3) Pay attention to reducing water and soil erosion on the site and prevent natural disasters caused by construction, Increase the green space area and reduce the heat island effect.

2?1?2 Optimize the layout structure

Optimizing the layout structure should emphasize the overall concept and obtain a good living environment through the treatment of the structure itself. The energy-saving design of the industrial building master plan should take overall consideration and comprehensive optimization of the overall layout, factory layout and indoor environmental conditions, so that the plan not only meets the production process requirements but also saves energy and land. In the master plan planning stage, we should not only consider the reasonable design layout to avoid the intersection of people and logistics; we should also consider how to combine the environment to maximize the use of natural resources such as solar energy and wind energy; arrange the power workshop and public auxiliary facilities close to the load center to make the pipelines short to reduce the loss of lines and pipelines to reduce energy consumption; at the same time, efforts are made to create garden-style industrial buildings and introduce greening into industrial buildings. On the one hand, it is for energy saving considerations, and on the other hand, it is also the pursuit of a life that strives to be close to nature, for Producers create a friendly and comfortable working and production environment.

2?2 Energy-saving design of green industrial buildings

2?2?1 Reduce building energy consumption and improve energy utilization efficiency

According to a survey, Among the investment in construction projects completed in my country in recent years, the ratio of industrial buildings to civil buildings is approximately 53%:47%. Therefore, improving the awareness of energy conservation in industrial building design, reducing energy consumption in industrial buildings, and exploring effective methods of energy conservation in industrial buildings have become increasingly urgent issues that require in-depth research and solution.

Industrial buildings are larger than civil buildings. When infrastructure investment is tight, the thermal performance of the outer envelope of industrial buildings is usually lower than that of civil buildings. In fact, this "saving" measure will cause the factory to waste a lot of precious non-renewable resources in the future use for many years. Although it saves one-time investment, it increases the energy consumption all year round, which is uneconomical in comprehensive comparison.

The outer envelope of a building is in direct contact with the outside world and is the main way for indoor heat to be lost. In the share of heat transfer and heat consumption of the building envelope, the roof accounts for about 7% to 8%, the exterior walls account for about 23% to 34%, and the doors and windows account for about 23% to 25%. Therefore, when architects design building planes and facades, they need to incorporate the concept of energy conservation into them, so that the number, location, size, thickness of exterior walls and facade shapes of doors and windows can be organically combined to meet the external environmental needs of the production process. , and reduce energy consumption. When designing the envelope structure, use high-efficiency thermal insulation exterior wall and roof systems to reduce heat consumption. The advancement of modern technology has provided a variety of solutions for lightweight, high-strength, and efficient composite thermal insulation envelope systems; secondly, door and window openings For weak parts of the building envelope, high-efficiency doors, windows, curtain wall systems, and high-performance glass can be used to effectively improve the thermal insulation performance of building doors and windows by setting up door buckets, hot air curtains and other technical means. During the design, we strive to improve the thermal stability of the indoor environment, and use various technical means to effectively solve the problem of passive heat dissipation and heat absorption in the building, reduce dependence on equipment, and reduce building energy consumption.

The current popular environmentally friendly building materials and products on the market mainly include: new wall materials, new waterproof sealing materials, new thermal insulation materials, decoration materials and new inorganic non-metallic materials. According to the recommendations of the World Health Organization, healthy housing should be able to keep the residents in a good state physically, mentally and socially. The most important specific indicator that should be achieved is to avoid the use of toxic and harmful building decorations as much as possible. Materials, such as coatings containing high volatile organic compounds; plywood, fiberboard, and adhesives containing high levels of formaldehyde and other allergic chemicals; granite, marble, ceramic tiles, gangue bricks containing high radioactivity; asbestos fibers containing fine asbestos fibers Cement products, etc. Therefore, environmentally friendly building materials should be carefully selected and appropriately used to minimize the adverse effects of building materials on the environment and human health. Avoid using materials that produce radioactive pollution. Solvent-based paints, chemical fiber blankets, composite boards and other building products may release volatile organic compounds (VOCs) such as formaldehyde into the air. These chemicals not only affect construction workers and building use It will also increase the dust and organic matter pollution in the environment. In fact, the design concept of environmentally friendly building materials reflects the concept of green environmental protection.

The current situation of the use of energy-saving and environmentally friendly materials in my country. For a long time, the Chinese have been accustomed to thinking of themselves as citizens of a country with vast land and abundant resources. From the large-scale export of disposable chopsticks to the development of thousands of illegal small coal mines, how to make It has become an urgent problem for more Chinese entrepreneurs to establish energy conservation awareness and for citizens to establish energy conservation and environmental protection. As for Shanghai, which has a rapidly developing domestic economy, there were still very few real energy-saving and environmentally friendly buildings in Shanghai in 2003. Most people were used to cold winters and hot summers, and did not have much clear concepts about green and energy-saving buildings. Nowadays, with the strong support and promotion of the government, there are gradually more energy-saving and environmentally friendly buildings in Shanghai. Some new projects, such as the World Expo that attracted world attention, Oasis Skyway Garden Hotel, Zhangjiang Science and Culture Exchange Center, and Pujiang Zhigu Investment Service Building , Anting New Town, Qingpu Villa, Chongming Dongtan Ecological Farm, Jinshan Industrial Park and another Chongming Ecological Farm, as well as old house renovation projects in Putuo District, etc., will all meet the standard of being 75% more environmentally friendly and energy-saving than ordinary buildings in Shanghai. Therefore, in this context, how to integrate green and environmentally friendly artificial transformation concepts into our country's building structures is very meaningful for our country's sustainable development.

Summary: In summary, green environmental protection and energy-saving technology can not only save energy and protect the environment, it also plays an important role in meeting residents' needs for building functional aesthetics. In actual building construction, we need to choose appropriate green, environmentally friendly and energy-saving technologies. This technology can be based on naturalistic concepts, artificial transformation concepts, or a combination of the two. In short, our ultimate goal is to Minimize environmental investment to achieve maximum social and economic benefits.
