Green building moving forward in exploration?

According to the specific objectives proposed in the plan, from now until the end of the Twelfth Five-Year Plan, we will vigorously promote the development of green buildings and green ecological urban areas, build 654.38 billion square meters of new green buildings, and implement 654.38+000 demonstration constructions of green ecological urban areas (planning new urban areas, economic and technological development zones, green ecological demonstration parks, etc.). According to the document, in order to guide real estate development projects to implement green building standards and encourage real estate development enterprises to build green residential areas, starting from 20 15, more than 50% of new real estate projects in municipalities directly under the central government and towns in eastern coastal provinces will strive to meet green building standards.

What is the significance of the development and promotion from green buildings to green ecological urban areas? What are the key problems in the practice of green building? How to advance in exploration? The existence of these problems undoubtedly makes the development of green buildings become the focus of the industry again. The difference between green building and ecological building Green building is a comprehensive methodology to solve the energy crisis and realize environmental benefits. It is not only the optimization and integration of a large number of green technologies, but also contains rich economic, social and cultural contents. At present, the three elements of green building generally recognized in the world are: maximizing the utilization of resources and energy, minimizing the environmental load and creating a healthy and comfortable life. Green building emphasizes the maximum utilization of resources and energy, minimizes the damage to ecology and environment, takes the maximum energy efficiency as the core, and comprehensively improves the soil, topography, mountains and rivers in the natural ecosystem to serve human beings, which is to develop green buildings and cities with wisdom.

Ecological architecture emphasizes the harmony between nature and people, treats the environment with a traditional and balanced view, and creates a green life. It should be said that there are similarities and differences between green buildings and ecological buildings. Because of this, it is easy to cause people to confuse green buildings with ecological buildings. If the problem is not deliberately complicated, the so-called "green building" is a building with resources, energy saving, environmental protection, health, comfort and energy saving, and the essence of ecological building is to protect and utilize nature and create a comfortable life with a normal heart. They are two aspects of the ideal environmental goal of sustainable development.

The fundamental goal of building energy conservation is to meet people's requirements for comfort with as little energy consumption as possible. But saving energy does not mean not consuming energy, so we can't simply use the word "saving". It is particularly important to emphasize that the focus of green energy conservation is to maximize energy efficiency and utilization, not to return to the life of an ascetic monk like the crypt or cave of primitive human beings. It is meaningless to talk about energy saving without comfort.

Energy saving is not the same as high-cost building energy saving, which needs to increase some upfront investment, but it is not the same as high cost. Through comprehensive quantitative energy-saving technology and computer simulation guidance, universally applicable energy-saving technologies, materials and practices can meet the needs of low-cost investment of quantitative energy-saving technology. Advanced foreign technologies, such as low energy consumption and high comfort technology that has been implemented in Europe for many years, can be gradually localized through practice. Through the concretization of building quality and indoor comfort goals, the integration, optimization and clarity of building design, materials and equipment selection, all energy-saving goals can be quantified and specific to every household. Therefore, the increased cost input for energy saving can be reasonably distributed, and the commercial value and market return of the building can be maximized. It is particularly important to emphasize that building energy-saving technology cannot be mystified. In order to sell houses, many developers put up slogans and slogans such as "Farewell to the era of air conditioning and heating", "Constant temperature and humidity" and "High-tech and high cost", which frightened a group of developers and users. In fact, energy conservation is around us, and we can integrate it with low investment on the basis of existing, easy and universal technologies. It is important to make full use of passive design principles and methods, that is, to integrate resources, rather than the so-called technical superposition. Now it is necessary to popularize and quickly popularize new technical concepts so that everyone can enjoy a house with high comfort and low energy consumption.
