subject: China's Carbon Reduction Standards For Building Speed Push "full Life Span," - [print this page] As "life expectancy is only 30 years of Chinese Architecture," the statement was public concern, and the other building energy efficiency standards have become the focus of the industry.
Island United Group 5 co-Lu, vice president of international demand, told reporters that the calculation of carbon emissions, construction methods and standards need to change, the most important thing is simply to change the current concern about the construction part of the carbon emissions reduction, but should start from the design links to building life cycle (70 years or more) to design the building carbon emissions standards. Ministry of Housing and Urban
building energy efficiency and technology Wu Yong, an inspector at the sixth Green Building Congress, said in the past only concerned with whether the single building energy saving building design standards, the next concern is how the regional of promotion; simply concerned about the construction part of the past should be to focus the design, construction and operation until the removal of the entire life cycle; before simply focus on energy efficiency, should be converted to full consideration, that is concerned about energy, water, land and materials , environmental protection.
With the rise of low-carbon economy, many buildings are made of low carbon building hope, but the lack of low carbon building standards status, become a hindrance, but there is also the case for low carbon building quite a mixed bag.
Seeking Lu said that China should speed up the evaluation of low carbon building standards and design standards steps. Recently, Germany DGNB (GermanSustainable BuildingCertificate, Germany, sustainable building certification system) green building standards is the biggest bright spot for the first time in the construction of the full life cycle carbon emissions into the scientific method.
DGNB assessment of technical systems for sustainable building construction principles calculations of carbon emissions is: calculate the construction materials production, construction, use, dismantle and re-use every step of the process of carbon emissions and add to form a construction life cycle carbon emissions.
Life cycle carbon emissions of the significance of computing is that it can correct the current energy efficient building understanding some of the errors.
Present, some energy-efficient buildings using simple pursuit of more new Energy Or energy-saving technology, while ignoring the mutual coordination and the combined effect could be achieved. The results will become a simple technology stack and a list of the construction of the "energy saving" construction and can not achieve real energy conservation and Environmental protection Effect.
"Blind promotion of architecture in the city of photovoltaic power generation, wind power technologies, the application of these technologies are many restrictions, the ultimate energy saving effect is limited," said Lu demand.
Deputy Minister of Construction Qiu lived also stressed the need to take the whole life cycle analysis, design, construction, operation, especially the removal of recycling have to make our buildings to minimize the interference environment, building life should be From now on average 35 years to 100 years.
Government departments and industry to develop evaluation criteria for low carbon building speed of the appeal, the background is the building energy conservation for the realization of "low-carbon society" meaning. Built according to the Department of
live statistics, 43 billion square meters of existing buildings, construction of 16 additional annual increase of 20 billion square meters, the current building-related energy consumption in China accounted for 46.7% of social energy, including energy consumption of buildings (including the construction of energy, life energy, heating and air conditioning, etc.) about 30%, and the energy consumption of building materials in the production process of 16.7%.
Now new construction in China each year, 99% of high-energy buildings; the existing building of about 43 billion square meters, only 4% of energy efficiency measures taken.
Therefore, building energy efficiency in recent years has been the main push of the proposition. Wu Chung said the Ministry of Housing and urban and rural areas in the building energy conservation goals set in two stages: the first phase, to 2010, new buildings for over 1 / 3 to achieve green building and energy efficient building standards.
