These buildings are “green”!

It is the first fabricated wood structure zero carbon building in China.

In July last year, the commissioning of phase I project of station buildings 3, 6 and 7 of river water source heat pump and supporting pipe network was completed, providing stable energy supply for the citizen center and service trade building in the new area.

Among them, the integrated technology of ground source heat pump and building solar photovoltaic power generation, the utilization of renewable energy is greater than 50%, and the comprehensive energy-saving rate is greater than 65%.

This year, Section 2 of zone 1, Section 1 of zone 3, 2A1 and 2A3 of underground space will be positive or negative zero, including the highest building about 500 meters in the core area will also “float out of the ground”.

In 2020, the annual power generation of Nangang will be 30 million kWh and the annual carbon dioxide emission will be reduced by 20000 tons.

Upon the completion of the whole project, the six energy stations of the river water source heat pump can provide efficient, low-carbon and stable cooling and heating services to 8.75 square kilometers and nearly 12 million square meters of buildings in the core area and some tunnel areas of the new area, saving 140 million kwh of electricity consumption for the new area every year, equivalent to burning 46900 tons of standard coal less.

Carbon dioxide emissions will reach the peak before 2030 and strive to achieve carbon neutralization before 2060…

The underground space project in the core area of Jiangbei new area “the development and utilization of underground space can play an important role and make positive contributions to carbon peak and carbon neutralization.” Qian Qihu, academician of the Chinese Academy of engineering, analyzed the relationship between the development and utilization of underground space and green transformation such as carbon storage, energy, construction and transportation energy during the special academic report.

The design project “wisdom tree – future life of vertical community” of this building was officially released during the 16th Venice International Architecture Biennale, and was also collected globally as an international competition project of future architectural design in Jiangsu Province.

It is worth mentioning that thousands of photovoltaic glass will be embedded on the top of the house to provide clean energy after the building is put into use.

According to the calculation, the unit power consumption cost is saved by 30% compared with the original.

When I mention Changlu, I think of..

From top to bottom, the underground space is divided into seven floors: commercial floor, parking floor, municipal comprehensive pipe gallery floor, pipe gallery interlayer, cavity floor and two-story subway passage floor.

The concept of healthy, civilized and low-carbon development is a green gene deeply rooted in the new area.

It plans to build 19mw installed units on the roof of 205000 square meters of plant, which is expected to generate 13 million kwh per year and reduce carbon emissions by about 9000 tons; At present, it is planning to build an energy storage power station, and it is planned to invest 200 million yuan to build 100000 kwh energy storage device, so as to reasonably distribute the use of green electricity.

Today, the first chapter of a series of reports on energy conservation, carbon reduction and green new area will take you closer to the “green buildings” in the new area and see what they look like? Building 3 of talent apartment (plot 1) project in Nanjing Jiangbei new area is a future residential building and the first residential building with assembled composite structure in Jiangsu Province.

River water source heat pump regional cooling and heating system river water source heat pump takes the Yangtze River water as the cold and heat source, uses electricity to drive the heat pump unit, converts the cold and heat energy contained in the river water into the actual required temperature, and then provides cold and heat services for users in relevant buildings.

This is the greatest negative carbon emission and the greatest contribution.” realize multiple land use and improve land use efficiency.

Compared with the disadvantages of large power consumption, high noise, low energy conversion rate and easy to form urban heat island effect of the traditional central air conditioning system, the river water source heat pump air conditioning system is cleaner and more efficient.

The indoor full decoration rate reaches 100%, and the fabricated interior decoration technology and Si construction system are adopted.

Nangang is planning phase II photovoltaic power generation project.

With the concept of “smart tree”, the main structure is like a trunk, and its core tube, facade, wiring interface mode, energy utilization mode and smart pipe network system are integrated to the greatest extent, It is the most cutting-edge and exemplary intelligent residential building in China.

It adopts wood structure + photovoltaic power generation system to realize zero energy consumption and zero carbon emission of the whole building.

The deepest place reaches 48 meters, which is equivalent to an 18 storey building extending underground.

By 2030, the river water source heat pump regional energy project can achieve an annual carbon reduction of 38515 tons.

The pipeline system is separated from the main structure to minimize energy consumption in the whole life cycle of the building.

A picture of green mountains and rivers and picturesque mountains is slowly unfolding in the new area.

Green building, green finance, green technology and green life…

The talent apartment (plot 1) project in Nanjing Jiangbei new area also adopts sponge residential area, rainwater recovery, sky garden and vertical greening technology to control the total amount of site runoff and improve the ecological environment of the residential area.

In the future, the first floor of the building will be used as a green building and low-carbon exhibition hall in Jiangbei new area, and the rest will be community service space.

The whole wood assembly is adopted here, and the demand for energy in the building is greatly reduced through internal ventilation and roof skylight design.

Building 12 is a community service center and commercial center.

He said, “the use of underground space just puts these facilities underground, releases the ground space and creates a green ecology.

As the largest single underground space project in China, the underground space project in Jiangbei new area has been under construction for more than half of the total since its commencement in 2017.

The sand boat outlets has come, and the farmers’ market has become “smart”! Keep sprinting! Come to see the progress of major projects with Luo Qun.

In this year’s government work report, “doing a good job in carbon peaking and carbon neutralization” is listed as one of the key tasks in 2021; The 14th five year plan will also include accelerating the promotion of green and low-carbon development.

The “floor” here is not the residential floor height in the traditional sense, but divides the underground space into seven levels of “floors”.

Nangang is gradually increasing the application proportion of renewable energy power generation, making multi energy complementarity a necessary supplement to waste heat and residual energy power generation, and promoting energy structure optimization and low-carbon development.

At present, the self generated electricity of Nangang has accounted for 62.5% of the production electricity, breaking the historical record.

Nangang photovoltaic power generation project Nangang photovoltaic power generation project uses the roofs and slope protection areas of existing science and technology buildings and office buildings to build a series of photovoltaic power generation units with a total installed capacity of about 700000 square meters and 40 MW.
