Carbon reduction in the construction industry is by no means a fresh idea experts suggest strengthening the transformation of rural buildings

This year, 4 month , The Ministry of housing and urban rural development has issued the compulsory engineering construction specifications 《 General code for building energy conservation and renewable energy utilization 》, It is required that the carbon emission intensity of new residential buildings and public buildings shall be... Respectively 2016 The average reduction based on the energy-saving design standards implemented in 40%, Carbon emission intensity is reduced on average 7kgCO2/（m2·a） above .

The building environment and Energy Conservation Research Institute of China Academy of Building Sciences said , From the perspective of carbon emissions in the whole life cycle , The proportion of building operation stage is about 70%~90%, The proportion of building materials production is about 10%~30%, The proportion of construction is about 1%, Demolition accounts for about 1%; In terms of unit time , The production of building materials has the highest carbon emission intensity .

“ Carbon reduction in China's construction industry is by no means an easy solution , It must be implemented comprehensively from the perspective of the whole life cycle , This involves all aspects of architecture , Including green construction 、 Enclosure structure 、 Improve equipment performance 、 Smart operation and maintenance 、 Materials can be recycled .” For new buildings , By constantly improving the performance of the building envelope , Gradually update building energy efficiency standards , Improve energy efficiency of new buildings , Reduce carbon emissions ; For existing buildings , We should constantly improve the market-oriented transformation mechanism , We will improve the incentive mechanism for tax subsidies , So as to stimulate and improve the energy-saving level of existing buildings ; And in the rural building energy-saving transformation , It is suggested to strengthen the renovation of rural buildings in northern heating areas , Bring rural building energy conservation into the supervision .

The carbon reduction in the construction industry should form a new construction pattern dominated by low-carbon building materials . First , In terms of source reduction, a low-carbon goal oriented design method should be formed , From strength 、 Space and time are three dimensions to consider energy consumption and carbon emissions , Do not simply consider the reduction in strength ; secondly , It is necessary to establish new low-carbon environmental values and new concepts of system design , Besides focusing on the environment 、 energy consumption , We should also pay attention to the use of low-carbon structural systems , Pay attention to the low-carbon utilization of building materials ; thirdly , In terms of energy assets , The electrification and rebirth of heating hot water should be considered according to local conditions , The northern region should consider promoting low carbon through technological innovation 、 Zero carbon heating system ; Last , We should pay attention to the use of various disruptive low-carbon technologies , For example, intelligent operation and maintenance of existing buildings , Including based on “ Number twin ” Overall optimization of energy consumption in physical space and virtual space environment .

Besides , Some experts think , The core of reducing carbon emissions is the traceability and fairness of emission reduction data , With the improvement of digital infrastructure and solutions , Building digitalization will become building “ Double carbon ” An important driving force for the achievement of goals . One side , Due to the dispersity and intermittency of renewable energy , Including micro grid 、 Energy storage system 、 Power grid dispatching will rely more on digital technology . On the other hand, the safe power system with interconnection function helps the operation and maintenance team to quickly respond to any crisis , Intelligent management can also heat itself according to the situation of the building 、 Cooling or ventilation , energy conservation .

According to the latest statistics , By the end of this year 6 month , The demand for environmental engineering talents in the construction industry has increased significantly over the same period last year .

In terms of specific positions , Enterprise information display , By 6 month , The talent needs of environmental engineers are 12.5%、 The talent demand of energy engineers is 12.3%、 The talent demand of flue gas treatment engineer is 12.4%、 The talent needs of purification engineers are 12.8%、 If there is a demand for the above positions , Flatland has what you want .

In terms of specific regions , data display , By the end of this year 6 month , hebei 、 Henan 、 The demand for environmental engineering talents in Heilongjiang has maintained a certain growth . Growth compared to the same period last year 12.5%.

From the specific information , The latest enterprise information shows , Henan rongzhijian Construction Labor Service Co., Ltd 、 Henan haoze Construction Engineering Co., Ltd 、 Zhangjiakou Guolin building materials Co., Ltd 、 Zhangjiakou tuojing Construction Engineering Co., Ltd 、 Bei'an Yunsheng Trading Co., Ltd 、 Heihe Dongyan economic and Trade Co., Ltd. has a talent demand for the above environmental engineering positions .

With the implementation of the general code for building energy conservation and renewable energy utilization , The green and low-carbon development path of the construction industry has become more clear .“ Open source throttling ” Full cycle carbon reduction , Will realize the construction industry “ Carbon reduction ” and “ Development ” A win-win situation .
