Development Zone: Develop green energy-saving buildings! Development zones do this

Source: Development Zone

In recent years, under the guidance of the development concept of "innovation, coordination, green, open and sharing", the development zone has actively practiced the concept of green development and built a green ecological and low-carbon park. In the field of construction, vigorously promote the green transformation of development mode, promote green energy-saving buildings, and comprehensively explore the new path of "green building" development.

The development zone of Lianyungang First People's Hospital, which has just been completed and put into use in 2023, is designed and constructed according to the two-star standard of green buildings. After the completion of the project, the proportion of heating and air conditioning load reduction is 14.46%, and the proportion of domestic hot water provided by solar energy is 54.04%. After acceptance by experts, the five categories of safety and durability, health and comfort, convenience of life, resource saving and environment livable score are all higher than 30% of the full score value stipulated in the standard, and fully meet the requirements of all control items in the Green Building Evaluation Standard.

The development zone not only adopts green energy-saving design in the new buildings, but also carries out ecological energy-saving transformation in the completed public buildings. The first phase of the New Hailian photovoltaic power generation project, which was completed last year, has a total installed capacity of 2.64MW, and a total of 4896 monocrystalline silicon photovoltaic modules have been installed, distributed on the roofs of Huada Science Park and Sino-German Small and Medium-sized Enterprise Park. The project adopts the green electricity mode of "self-use, surplus electricity online", and the average annual power generation is about 2.7 million KWH, which is equivalent to saving about 850 tons of standard coal per year and reducing about 2300 tons of carbon dioxide emissions. The construction and operation of the project can improve the power structure of the system and reduce air pollution.

As one of the green buildings, prefabricated buildings are also being vigorously promoted. The project of education training and living supporting area in the core area of China Medicine Port adopts the construction mode of passive energy saving and active optimization, and is currently being constructed in accordance with the requirements of two-star green building and prefabricated building. The exterior wall of the building is a unit curtain wall, the inner wall is made of prefabricated wall panels, and the floor panel is made of laminated panels, and the assembly engineering application exceeds 45%. The use of assembly process can shorten the construction period, save resources and reduce pollution to the greatest extent. The promotion and application of prefabricated buildings cannot be separated from the supporting development of the construction industry. At present, the district has built 3 construction industry supporting projects, 10 precast concrete components, steel structure components production lines, with a total annual capacity of 163,000 tons, laying a solid foundation for the modernization of the district's construction industry.

According to the relevant person in charge of the Housing and Construction Bureau of the Development Zone, at present, the new civil buildings and public buildings in the district fully implement the green building energy-saving design standards. According to statistics, the completed area of green buildings and prefabricated buildings in 2022 is about 760,000 square meters, and the newly started green buildings and prefabricated buildings in 2023 are about 850,000 square meters. "In order to vigorously develop green buildings, the development zone housing and construction departments, examination and approval departments strictly check the examination and approval of each link, in the project planning and application stage, the construction drawing review stage, the construction permit examination and approval process, the commercial housing pre-sale stage are strictly implemented the relevant national and provincial green building regulations and standards, to ensure that the building energy efficiency policies are truly implemented." The person in charge introduced.

In the next step, the development zone will continue to develop green buildings and prefabricated buildings as an important starting point for the transformation of old and new momentum in the field of residential construction, take government-invested public buildings, affordable housing and other projects as a breakthrough, comprehensively and deeply promote green energy-saving and low-carbon buildings, strengthen scientific and technological innovation capacity and standardization construction of engineering construction, and do a good job in the promotion and application of green buildings. The green background of the high quality development of Huzhi Development Zone.
