The Shekou Building project in Nanshan District, Shenzhen, combining appropriate active and passive technologies and renewable energy solutions, was included in the second batch of “Shenzhen Near Zero carbon emission Building Pilot Demonstration Project”, and won the national “Near zero Energy Building Design Evaluation Logo” award.
ABB provides ZEE600 smart energy management system, eStorage smart energy storage hut and EVinn TA charging pile, which realizes photovoltaic consumption and load optimization regulation through the precise regulation of source-charge-storage, saving energy and reducing carbon.
ABB helps customers create light storage direct and flexible demonstration, innovative application of DC power distribution technology, DC system energy tuning technology.Shekou Building, built in 1994, is an office-oriented public building with a total construction area of about 20,000 square meters and a total height of about 90 meters. Since the Shekou building has been put into use, due to the old facilities, high energy consumption, security risks and other problems, it is urgent to reform.

ABB assisted Shenzhen Shenhuitong Energy Technology Development Co., LTD., a wholly-owned subsidiary of Nanshan State-owned Shenhuitong Company, to actively explore the implementation path of near-zero energy consumption and near-zero carbon emissions for Shekou Building. On the basis of active and passive technology applications such as roof insulation, replacement and upgrading of exterior Windows and curtain walls, and transformation of air conditioning into heat pump type multi-connection and independent fresh air system, Shekou Building builds an intelligent energy management system integrating energy optimization, energy consumption analysis, carbon emission management and power monitoring through the application of roof PV and building PV integration technology. Achieve full use of green energy and reduce carbon emissions.

“Light storage direct and soft” technology is a new building distribution technology that further realizes electric energy substitution and grid-friendly interaction on the basis of improving building energy efficiency, and is an important technical path to support carbon neutrality in the building field [1]. ABB has innovatively applied DC power distribution technology and DC system energy tuning technology on the Shekou Building demonstration floor. ABB eStorage Smart Energy Storage House solutions adopt an integrated and highly integrated concept, providing an integrated solution from the end battery to the junction point.

Through ABB ZEE600 intelligent energy management system, based on the intelligent algorithm of self-iterative photovoltaic power generation prediction and load prediction, energy tuning, flexible and accurate adjustment of energy storage, charging pile, air conditioning, lighting and other loads, in order to absorb and release electrical energy in the form of “breathing”, gently optimize the energy consumption curve. It is estimated that the annual photovoltaic power generation of the project will be 314,800 KWH, the carbon emission will be reduced by about 142 tons a year, the comprehensive energy saving rate will reach 75.08%, the energy saving rate of the building body will reach 30.16%, and the utilization rate of renewable energy will reach 47% [2]. Through energy optimization, the local consumption rate of new energy is more than 90%, and the cost of electricity purchase is expected to be saved by 50%[3]. Dc energy control technology has been applied to improve the energy utilization rate by about 5%[4].

The relevant person in charge of Shenzhen Shenhuitong Investment Holding Co., Ltd. said, “In response to the national” double carbon “strategic goal, we actively explore and try first. ABB, as a global technology leader, has opened up new ideas for the renovation and upgrading of Shekou Building with its multi-strategy intelligent energy management system of “source network charge and storage” and safe, stable and reliable intelligent energy storage hut. In the future, we will deepen cooperation with ABB, actively build an integrated demonstration application platform for emerging energy technologies, and strive to contribute to the green force of Nanshan District to accelerate the construction of a world-class innovative coastal central city.”

Yongzhan Zhao, President of ABB Electric China, said: “ABB and ShenHuitong have joined hands to create a near-zero energy consumption and near-zero carbon transformation of the Shekou Building. Shekou is the starting point of China’s reform and opening up. As a landmark building, Shekou Tower has witnessed the changes and development of Shekou. Its renewal and upgrading have provided a solution for the zero-carbon transformation of existing high-rise buildings, and also contributed a good strategy for the green and low-carbon development of the construction field during the “14th Five-Year Plan” period. In the future, ABB will continue to use technological innovation to enable green economic and social development, and work together with partners to create a safe, smart and sustainable future!”
