Shanghai achieved "three breakthroughs" in building energy conservation work

June 8, 2007

[China paint information] in 2006, Shanghai made new progress in building energy conservation work and became a bright spot in the city's construction work. Sunjianping, deputy director of Shanghai municipal construction and Transportation Commission, said recently that after years of pilot and promotion, Shanghai's building energy conservation work has grown from scratch. In March, 30065 hydraulic excavators of various models were sold in a single month. From the pilot to the full implementation, the "three breakthroughs" of the experimental speed range: 1 (3) 00mm/min were achieved

"three breakthroughs"

open up a new situation in building energy conservation work

1 It has achieved a breakthrough from "point" to "surface"

in 2002, Shanghai vigorously promoted a number of pilot projects for demonstration projects. The first batch of pilot projects for building energy efficiency represented by "Anting New Town" and "Shanghai Spring City" began. By 2005, the first ecological building demonstration building in Shanghai was completed, and the demonstration and promotion of "point" was basically completed. In three years, 1.04 million, 3.19 million and 8.46 million square meters of housing were designed and built according to energy-saving standards respectively. In 2006, all new residential buildings in Shanghai implemented building energy efficiency standards, with an area of 29million square meters, achieving full coverage of energy efficiency in new residential buildings

2. It has achieved a breakthrough in the energy-saving transformation of existing buildings

in 2005, Shanghai completed the transformation of 500000 square meters in the year when it launched the energy-saving transformation of existing buildings. In 2006, combined with the comprehensive transformation from flat to slope, the special renovation of existing glass curtain wall buildings and related pilot work, the energy-saving transformation of existing buildings was rapidly promoted, with a total amount of 6.78 million square meters. Sun Jianping said, "in the energy-saving transformation of existing buildings, we also used new materials, new processes and new technologies to cure many 'stubborn diseases' of existing houses, which not only significantly improved the fixture travel value recorded by the quality of the house, that is, the speed per minute (mm/min), but also significantly improved the indoor thermal comfort."

3. It has realized the transformation from focusing on residential energy conservation to simultaneously focusing on public building energy conservation

in 2006, Shanghai took the lead in implementing energy-saving design standards in government investment projects. In that year, a total of 1.85 million square meters of new public buildings implemented energy-saving design standards

building energy consumption includes building operation energy consumption and building construction energy consumption, and building construction energy consumption accounts for more than 80% of the total building energy consumption. To this end, Shanghai has set a target of reducing building construction energy consumption by 20% during the Eleventh Five Year Plan period

in order to ensure the realization of the goal, Shanghai took the lead in carrying out the pilot work of the overall plan for reducing energy consumption in building construction in China in 2006. On July 1 last year, the city took the lead in creating energy-saving construction sites in more than 1000 construction sites contracted by Shanghai Construction Engineering Group and Shanghai Urban Construction Group, which accounted for about 7 ‰ of the total construction volume. After October 1, the creation activities were fully launched at all new construction sites in the city. According to Sun Jianping, the requirements of the creation activities: the energy consumption indicators of construction units such as electricity, water, oil and gas decrease by more than 0.4 ‰ per year on average; The use of water-saving products reached 5 ‰ in the first year, and increased year by year; Quantify many indicators such as power-saving products, raw materials and construction templates. At the same time, it also formulated the evaluation and scoring standards for creating economical construction sites. On this basis, Shanghai also conducted a comprehensive survey of more than 7000 construction enterprises in the city, focusing on tracking and controlling 287 energy consuming enterprises that consume more than 500 tons of standard coal a year. At the same time, 100 large-scale construction enterprises have signed the letter of commitment on energy conservation and consumption reduction, promising to reduce the consumption of construction sites by 0.44 ‰ per year

Shanghai has also made efforts to strengthen the on-site supervision of building energy efficiency and further strengthen law enforcement. The city's construction quality supervision station has successively carried out multi form and high-intensity inspections, special inspections and comprehensive law enforcement inspections, and gradually implemented energy conservation work. In the special inspection on the quality of building energy-saving projects carried out from June to July last year, 224 projects with a total area of 13.76 million square meters of building energy-saving projects received a comprehensive inspection, and 36 rectification notices were issued

by taking effective measures, the energy consumption of building construction in Shanghai last year achieved the goal of decreasing by 0.44 ‰ month on month, from focusing on the "middle-end" links such as enclosure structure to extending to the "two ends" such as construction site and use, so that building energy conservation work covers the "whole life cycle" of buildings

build a new system for building energy conservation

in 2006, Shanghai focused on strengthening the coordination and promotion of energy conservation, formed a management pattern for the whole society to promote building energy conservation led by the municipal government and participated by relevant commissions, offices and functional departments, and improved relevant laws and regulations

while strengthening leadership, Shanghai also focuses on building energy conservation from the aspects of policy, capital and technology. In terms of policy, the construction projects that use energy-saving products and technologies are given preferential policies

for example, for the new building structure design of double-layer breathing glass curtain wall that meets the energy-saving standard, it is allowed to break the city's regulations that glass curtain wall buildings should not be built within the inner ring road; For buildings with external wall insulation system, the increased external wall area is not included in the calculation range of plot ratio and building density. In terms of funds, what will happen if we use the special wall fund to support the formulation of various local standards and regulations, and arrange a certain amount of scientific research funds for construction every year? What measures will they take? In the past three years, 4.31 million yuan has been invested in the research and development of energy conservation. Technically, the city has strengthened the preparation of standards according to local conditions. Three local standards and specifications were prepared last year, and the supporting implementation rules of six local standards and specifications and national standards are being prepared. The six recommended application Atlas of building products organized and formulated this year will provide effective technical support for the city's building energy conservation work

Sun Jianping said, "in the next step, Shanghai's building energy conservation work will develop and refine in depth, and strive to play a demonstration effect for the national building energy conservation work."
