At present, China has the world's largest amount of new buildings last year's national, annual 2 billion square meters of new buildings. However, in this land of make on the floor, "short-lived building" after another, split five-star four-star cover, unfinished and bulldozed. "Once removed to create the GDP, then cover again and also created a GDP", in view of the error performance under the guidance of a large number of "youth" a construction put on the field of non-normal "death" of the tragedy.
Industry experts pointed out that "short-lived building" and building "saving society" contrary to the spirit of serious, even seriously out of line with the scientific concept of development. The consequences not only a huge waste of social resources, and produce a large number of construction and landfill waste are piling up around the city, not only occupy the land, which contained a variety of harmful chemicals is also a serious corrosion and pollution of surface groundwater sources, is lethal. In cities, people blindly demolished old buildings and building new, not only separates the city's historical context, and the urban landscape has been severely damaged.
According to authoritative statistics, China's building, the average "life" of only 25 years to 30 years. Repeating the process of building our country created the two world first: the first is a maximum of consumption of the world's cement and steel; Another first is the production of the world's largest construction waste - up to 400 million tons per year . Amount of construction waste accounts for 30% of total waste to 40%. There is an article pointed out, China may become the world's largest construction waste country. Short-lived construction gives us multiple problems, with energy saving deepening of this policy, urban renewal and transformation into the construction of green building experts present the most concern.
In view of the short-lived building to mankind's survival harm the environment, architects proposed the transformation of both buildings are not energy-efficient cities in extending its life should also be required to meet the state building energy efficiency standards . Therefore, the construction experts proposed to "improve and enhance their work performance and safety performance, increase defense earthquakes, typhoons and other natural disasters, protection of life and property safety, improve the efficiency of resource use, energy, land, water, materials, environmental protection and improvement, to extend the life of the existing building as a whole "as the goal of transforming the existing green building new ideas. Experts suggest that relevant departments should develop investigation, detection, identification, assessment, design, construction, engineering, operations management and other cities and acceptance of green building renovation technology standards to allow the renovation of building green is no longer in isolation, but the use of both building a new model of green renovation renovation, the city buildings as a green renovation project to transform the system in order to achieve the desired goals. This proposal will guide future building renewal and transformation toward a more healthy and green and perfect trajectory, so that green building everywhere.
