A house saves 15,000 degrees of air -conditioning electricity in Hefei, which will be lower -carbon livable

Recently, the reporter learned from the Urban -Rural Development Bureau of Hefei that Hefei has excessive completing the task of improving the energy efficiency of the national public building. In response to the national "carbon -peak peak, carbon neutralization" strategic target task, from April this year, the city's energy -saving standards for public buildings in the city were required to further improve.

A building of a building is about 15,000 degrees of electricity in the year

In the Hefei Technology Industrial Park, the whole building of the A6 -floor building is "hidden mysterious machine". This building is actually a demonstration project of key cities in the energy efficiency of public buildings in the city.

As an old public building, the energy -saving transformation area of ​​the A6 floor reached 26,217 square meters. Through the implementation of a series of energy -saving transformation projects such as air conditioning, lighting, water supply, and elevator, and increasing the construction of renewable energy utilization and energy monitoring systems of the building, the building energy consumption is scientific management, and the building energy consumption has decreased significantly compared with the previous. The building construction of the air -conditioning intelligent control system is built. According to estimates, the average increase in the temperature in the summer can realize the energy saving rate of about 5%of the air -conditioning system, and the annual air conditioning power consumption is about 15,000 degrees.

In 2017, Hefei was approved by national public buildings to improve the energy efficiency of key cities. To this end, municipal finances have taken 30 million yuan of special awards for special awards for the construction of existing construction energy -saving transformation projects and supporting capabilities, and stimulate the enthusiasm of public building property owners and enterprises to carry out energy efficiency. In response to the national "carbon -to -peak, carbon neutralization" strategic target task, Hefei City fully promoted the energy conservation and emission reduction work with existing public buildings, and exceeded the energy efficiency of national public buildings to improve key cities. According to statistics, a total of 57 energy -saving reconstruction projects were implemented, with an area of ​​1.9316 million square meters, with an average energy saving rate of 18.47%. A total of 23.907 million yuan in financial awards were allocated, and 192 million yuan of social investment energy conservation and renovation funds were leveled, and the annual total energy -saving energy was equivalent to 11,223.94 tons of standard coal.

High -tech products such as ultra -quiet doors and windows will gradually be applied

Authoritative surveys show that with the development of the economy and society in recent years, domestic building energy consumption accounts for about 40%of the total energy consumption of the whole society. Among them, the energy consumption of the outer doors and windows accounted for about half of the energy consumption. Therefore, the key to building energy conservation needs to pay attention to improving energy -saving technology of outer doors and windows.

At present, the windows of most high -rise residential communities in Hefei use double -layer hollow glass. Some high -tech enterprises are trying to develop a new glass of three or even four floors to improve energy -saving and insulation performance.

"We are developing a four -layer glass window. The insulation and thermal insulation performance is particularly strong and can be used for passive houses. It is equivalent to the cool feeling of 26 ° C in the room without turning on the air conditioner in summer, and the energy consumption will become Very small. "Hou Linyan, director of the R & D director of Anhui Jiawei New Materials Technology Co., Ltd., can be foreseeable that high -tech products such as energy -saving doors and windows, ultra -silent doors and windows, etc. will gradually apply to the lives of Hefei people in the future.

Outlook: Promote the development of the scale of ultra -low energy consumption buildings

In recent years, Hefei has always adhered to the "application, economy, green, and beautiful" building policy, and comprehensively promotes building energy -saving, green buildings, and renewable energy.

In order to promote energy conservation of the building, Hefei introduced the first green building development regulations- "Regulations on the Development of Green Building in Hefei City" as the national capital cities. From October 1, 2017, the new civil buildings are designed and constructed in accordance with the standard of green building standards. Essence The city's green building is completed in the proportion of new civil buildings, from 33.5%in 2017 to 93.4%in 2021. In 2022, Hefei Government Affairs New Area was approved by provincial -level urban and rural green development demonstration cities (low -carbon areas).

In addition, Hefei strictly builds energy -saving market management. At present, relevant departments are studying and formulating 75%energy -saving design standards. In the next step, the city will focus on the "carbon peak carbon neutralization" goals, improve the energy efficiency of building equipment, vigorously promote renewable energy applications such as solar energy, air energy, and geothermal energy, and promote the large -scale development of super low energy consumption and near -zero energy consumption building.
