New wall materials make the house warm in winter and cool in summer, public lighting all from wind power, rainwater after recycling can irrigate green space, solar energy system can guarantee 24-hour hot water, these will not increase the owner's additional expenses, but also save a lot of shared expenses, living in such a low-carbon, environmentally friendly, energy-saving and money-saving community will not let you move? This is the standard of Zhengzhou City Building Energy Conservation Demonstration District. According to statistics, the urban residential buildings completed in Zhengzhou every year are as high as tens of millions of square meters, and the buildings that can meet the residential energy-saving design standards are less than 10% of the total completed residential buildings, and buyers can only look at the buildings and sigh. "The low enthusiasm of developers is the primary reason for the embarrassment of energy-saving building development." A person in charge of the Zhengzhou construction department said that the cost of building energy-saving houses is about 10% higher than that of ordinary houses, and the construction cost per square meter is also "rising" to 100 to 200 yuan higher. Some developers believe that there is not much difference between energy-saving buildings and ordinary houses on the surface. Consumers will not feel the energy-saving effect in the short term. In addition, the price of energy-saving houses is higher, and the market demand is not large. In terms of building energy conservation, it is better to do more greening to increase the selling points of real estate. The reporter learned in the interview that many consumers said that the main concerns of buying a house are housing prices, geographical location, household area, and community greening, educational resources, transportation and so on. The weak energy-saving awareness of consumers further affects the developer's emphasis on building energy efficiency. The difficulty of using renewable energy is also a "roadblock" in the promotion process ". The person in charge said that the construction of energy-saving buildings needs to use renewable energy such as solar energy and shallow ground energy to solve the building's heating and air conditioning, hot water supply, lighting, etc. The design angle, construction angle, and calculation coefficient are higher than Ordinary buildings are complicated and require high construction. Some developers are not willing to bear the "risk" brought by new things, and prefer to choose the traditional construction technology with high energy consumption. It is understood that Zhengzhou has comprehensively promoted renewable energy in public building projects and key projects invested and constructed by the government, and guided the development direction of the construction industry by widely using renewable energy technology in landmark projects such as Zhengzhou Library and Zhengdong new passenger station. According to the Zhengzhou Energy Conservation Office, every 100000 square meters of energy-saving buildings can save 748 tons of standard coal and reduce carbon dioxide emissions by 2000 tons. It can be seen that actively promoting building energy conservation plays an important role in achieving sustainable economic and social development. In order to further break through the market barriers, Zhengzhou plans to comprehensively promote renewable energy technology in the construction field next year, so that it can be designed, constructed, accepted and delivered simultaneously with construction projects. In principle, buildings that adopt but do not adopt renewable energy technology shall not pass the construction drawing review and construction acceptance.
