“In recent years, Beijing’s building energy efficiency has been fully promoted from a single area to multiple areas and entered a period of rapid development.†Recently, when interviewed by the media, Liu Xiaoqun, Director of the Office of Building Energy Conservation and Building Materials Management in Beijing, summed up the construction of buildings in Beijing in recent years. The basic situation of energy conservation and development. He pointed out that since 1988, Beijing has strictly implemented building energy-saving design standards and acceptance standards in new construction, Beijing’s building energy-saving work has changed from building energy-saving building to existing building energy-saving renovation, large-scale application of renewable energy buildings, public buildings Energy consumption operation supervision system construction, agricultural house earthquake-resistant energy-saving reform, green building, housing industrialization and other fields continue to deepen, and achieved certain results.
In the five years of the “Eleventh Five-Year Planâ€, Beijing vigorously promoted building energy conservation and emission reduction. The contribution rate of energy-saving and emission reduction in the construction sector to the city’s energy-saving and emission reduction has reached 39.3%, and it has saved 396 million tons of standard coal and 9.9 million tons of emission reduction annually. Tons of carbon dioxide capacity.
Improve the standard system, strengthen supervision and management
Liu Xiaoqun introduced that at present, Beijing has initially completed and continuously improved the technical standard system and supervision and management system for building energy efficiency, and has formed a relatively complete system of laws and regulations.
Since the "Eleventh Five-Year Plan", Beijing Municipality revised the "Measures for the Implementation of the People's Republic of China on Energy Conservation Law in Beijing" and issued the "Guiding Opinions on Promoting the Industrialization of Housing in this Municipality," and introduced support for renewable energy construction applications. policy. In 2011, Beijing drafted and published regulatory documents such as the "Energy Conservation Plan for Civil Buildings" of the "Twelfth Five-Year Plan" period in Beijing, which strongly promoted the building energy conservation in Beijing.
Beijing's building energy efficiency standards are at the forefront of the country. Since the “Eleventh Five-Year Planâ€, Beijing has implemented more than 20 energy-saving technology standards for various types of buildings, including the Energy Saving Design Standards for Residential Buildings, Design Standards for Energy Efficiency of Public Buildings, and Green Construction Management Regulations, which are 65% energy-efficient. The energy-saving standard system including energy-saving design, thermal insulation construction technology, energy-saving detection and evaluation, and renewable energy applications provide tremendous technical support for building energy-saving work.
"Beijing's implementation of building energy efficiency standards in the country's earliest, and continuously improve energy efficiency standards, is the first city to implement the implementation of 75% of building energy efficiency standards. At present, 75% of the "residential building energy efficiency design standards" is being revised." Liu Xiaoqun introduction. This standard is not only at the leading domestic level, but also reaches the advanced level of the world with the same climatic conditions.
In addition, Beijing has established a more comprehensive supervision and management mechanism for building energy efficiency, and implemented management systems such as project energy conservation assessment review, construction drawing design document review, energy conservation design review filing, and energy saving special acceptance record filing. Liu Xiaoqun said: “For newly-built buildings, Beijing must carry out energy-saving assessment review. After review and approval, the design can only be conducted. The design documents must also pass the energy-saving review. Apply for construction permits, special records should be carried out in the construction department. Acceptance and acceptance cannot be completed and put into use. Beijing conducts two energy-saving construction inspections each year."
Significant energy savings from cities to rural areas
In terms of building energy efficiency in new buildings, the implementation rate of Beijing's new building energy efficiency design standards has basically reached 100%. The proportion of energy-saving buildings in cities and towns reached 58.6%, and the proportion of energy-saving houses reached 77.2%, ranking first in all provinces and cities.
In the energy-saving retrofitting and heat metering of existing buildings, during the “11th Five-Year Plan†period, Beijing completed 46.73 million square meters of urban energy-saving reconstruction of existing buildings, completed 166 boiler houses and 498 district heating pipe network transformation. Since 2011, the city-level financial subsidies for existing building energy-saving renovations have substantially increased, and the transformation contents have changed from individual transformations to comprehensive transformation of old residential areas. In 2011, Beijing was approved as a key city for the national “Energy Saving and Heating Projectâ€. From 2011 to 2013, the existing residential building heat metering and energy-saving renovation projects were supported by the central government's 1.98 billion yuan in funds, and the municipal financial support standard was increased from the previous RMB 5 to 7 yuan per square meter to 100 yuan. Since 2012, Beijing has adjusted its single energy-saving renovation and earthquake-resistant energy-saving transformation to a comprehensive transformation including landscaping and the transformation of old facilities such as water, electricity, gas, and communications.
To promote the energy conservation and emission reduction of public buildings, Beijing has gradually established a large-scale public building energy monitoring system. At present, electricity consumption has been installed on 65 municipal office buildings and 258 large-scale public buildings, energy-saving supervision platforms have been established, a statistical report system for building energy consumption has been established, and energy audits and energy efficiency announcements have been carried out. It has created conditions for the introduction of energy consumption quotas and differential pricing policies.
Liu Xiaoqun said: “In recent years, Beijing has pushed building energy efficiency into rural areas and carried out earthquake-resilient energy-saving reforms of rural houses. Farmers have a poor economic foundation and poor living environment. They have to wear cotton quilts at home in the past. In the past, the farm house had to be refurbished in 15 years. The life of the new farm can reach more than 50 years."
It is reported that Beijing actively organizes the construction of new earthquake-resistant and energy-saving farmers' houses in rural areas and the pilot projects for the reinforcement of peasants' houses. It explores the mode of building small cities and towns and new rural construction. It adopts the form of awards and supplements, according to new construction, renovation and comprehensive reconstruction of each household. The standard of 20,000 yuan and 10,000 yuan per household for individual households will be rewarded to district and county governments. The award funds will be used by all districts and counties to make breakthroughs in the construction and policies of earthquake-resistant and energy-saving rural houses. By the end of 2011, more than 40,000 new farm houses have been built, and more than 63 thousand farmhouses have been converted. The winter temperature of the new farmhouse has increased by 6°C to 8°C, and the farmers call it the "warm heart project."
Beijing has also introduced renewable energy sources such as solar energy, geothermal energy, and biomass energy for heating and cooling in buildings, and accelerated the pace of large-scale application of renewable energy buildings. At the end of the “Eleventh Five-Year Plan†period, Beijing’s application of renewable energy has a floor area of ​​4%. In 2011, Beijing continued to develop the construction of renewable energy demonstration counties in Pinggu District and Yanqing County. At the same time, three new building integrated solar energy collectors and photovoltaic cogeneration technologies and other national renewable energy construction application technology and industrialization demonstration projects entered. Implementation phase.
Improve construction quality and promote green building
In order to improve the quality and quality of buildings and reduce the energy consumption during construction and use, Beijing has vigorously promoted the green building and housing industrialization in recent years.
By the end of 2011, Beijing had organized 28 demonstrations of green buildings and low-energy buildings. Since 2011, Beijing's green buildings have expanded from single buildings to low-carbon ecological parks, and three green building demonstration parks such as Changping District Future Science and Technology City have established green building promotion agencies, issued guidance and regulatory documents, and confirmed all parks. 100% of the building meets the goal of green building standards.
The pilot work of housing industrialization has also been fully carried out. Beijing was the first in the country to issue preferential policies for area awards, set up a joint conference system for housing industrialization, carried out scientific and technological research and organized pilot projects, and promoted prefabricated assembly systems, solar hot water systems, and overall kitchen and toilet applications. And full renovation solutions.
Liu Xiaoqun pointed out that in recent years, with continuous efforts and achievements, Beijing’s building energy conservation efforts have increasingly gained the support and recognition of the government, citizens, and the community. During the “Twelfth Five-Year Plan†period, Beijing’s building energy conservation bears 41% of the city’s social energy savings, and the task is arduous.
In the “Energy Conservation Plan for Civil Buildings in Beijing during the Twelfth Five-Year Planâ€, Beijing clarified that by 2015, the building energy-saving and green building work will maintain the domestic leading level and reach the overall goal of the international advanced level. It is believed that with the continuous development of building energy conservation in various fields, Beijing will be more blue and water will be greener, and urban and rural life will be even better.
