The era of opportunity for energy-saving renovations in buildings has arrived. Recently, the national level has made it clear that equipment upgrades will be implemented in many key areas in anticipation of tremendous market potential. It specifically pointed out that by 2030, the related investment needs will require an additional 2 trillion yuan each year. Against this backdrop, smart industrial parks have become important practical venues, and their construction paths have also gained industry consensus.

Overall, the construction mainly follows three major steps: First is to achieve online-ization—connecting a sufficient number of devices and monitoring data at various points; Second is to realize the integration of software and hardware—maximize the energy efficiency of hardware devices and integrate "equipment + system + service" to improve overall efficiency; Finally, continue to iterate—achieve optimal collaborative work of environment, buildings, and user needs through dynamic learning and adjustment in operation.

Among these, a core focus is the cost issue: how to achieve the above objectives at a reasonable price. This requires a clear calculation of return on investment and realization through more efficient operations. Firstly, by optimizing algorithms to reduce energy consumption, this direct benefit has been widely validated. Next, enhancing the user experience in the park can also bring indirect benefits. In the future, every building and space will incorporate smart features, a trend that cannot be overlooked.

In this process, both forward-looking cross-cycle planning and close team cooperation to implement the plans into specific actions are needed. The entire process is a systematic engineering challenge. Taking Midea Building Technology as an example, their practices may provide experience and ideas.

Take the NIO Center, which has the largest building area in the world, as an example; it serves not only as a platform for displaying cars but also as a model in building energy saving. However, it is often difficult to achieve both aesthetics and energy efficiency. As a partner, Midea Building Technology has provided an innovative solution: the MDV8 boundless multi-connection full life cycle smart solution.

In the equipment selection and design planning stage, high-efficiency and energy-saving equipment are adopted, providing significant energy-saving effects for the NIO Center's air conditioning system. While achieving equipment energy savings, there is also the challenge of how to dissipate heat efficiently in a limited space. Midea Building Technology proposed the best cooling solution through specialized simulation and optimization, ensuring high efficiency of air conditioning systems in tight spaces.

Facing the common problem of poor heat dissipation due to the pits on building rooftops, which may cause increased system pressure and energy consumption, Midea Building Technology has installed an intelligent sprinkler system on the top of buildings to effectively improve the heat dissipation conditions of outdoor air conditioning units. After the sprinkler system is activated, the effect is significant: the temperature inside rooftop pits drops by an average of 6.1℃, the indoor temperature also decreases by 1.0℃, and the operation energy consumption is reduced by about 12.6%.

In addition, the energy-saving renovation project of the NIO Center has gone even further. An in-depth analysis of smart monitoring revealed various spaces within the center with irregular energy consumption patterns. To address this challenge, Midea Building Technology introduced the i-housekeeper smart operations and maintenance tool; by implementing intelligent strategies, such as intelligent schedule management and regional temperature control, the annual energy consumption is expected to be reduced by 21.3%, saving up to 110,000 kWh of electricity.

The newly launched Midea 08 Space integrates Midea Building Technology's efficient air conditioning systems, smart elevators, and intelligent technology. This office building is built for Midea's internal staff and, along with the Midea headquarters building, Youth+ and the Art Museum, constitutes the Midea headquarters building cluster ecosystem. This not only continues the zero-carbon project but also demonstrates Midea Building Technology's comprehensive strength in hardware and software integration.

To address the parking space allocation management issues in the multi-space underground garage, Midea Building Technology has developed a smart parking system. By using zone management, fair lottery rules, and clear violation handling measures, the system ensures the efficient use of over 3,700 parking spaces shared by Midea headquarters building, Youth+ and Midea 08 space. The system is integrated with the Midea Staff Office app - MEIXIN APP, allowing employees to easily check their parking location, significantly optimizing the use efficiency of the underground garage and improving the work efficiency of employees.

While enhancing the experience and efficiency, Midea 08 Space also focuses on energy efficiency. The project has adopted Midea's magnetic levitation variable-frequency centrifugal chiller units to ensure stable and efficient operation under various working conditions. The machine room adopts a standardized design and construction approach, shortening the construction period by 30%. The control system uses Midea's multi-agent distributed control system, with machine room data integrated into Midea Cloud Efficiency Smart O&M platform, achieving cloud-based monitoring, data analysis, and energy efficiency management, reducing operational costs by more than 50%. The high-efficiency machine room's annual energy efficiency prediction value is over 6.0, increasing the energy-saving rate by 28% compared with traditional design, and it is expected to save more than 1 million KWh of electricity annually.

The introduction of a full life cycle equipment management strategy - Cloud Smart O&M increases the overall energy efficiency of Midea 08 Space equipment by 30%. This is thanks to various data collection methods, such as online direct reporting and system integration, which provide detailed data support for the operation and maintenance management of the park's mechanical and electrical equipment, solving the problem of improper maintenance. Park managers can easily grasp the status and location of equipment through the visual interface, achieving visual, automated, and traceable closed-loop unified management of equipment.

In today's world, which is moving towards a fusion of green energy and intelligent management, the photovoltaic panel system, an important component, does not work alone but is connected to a range of supporting equipment, including but not limited to inverters, energy storage products, and household appliances such as air conditioners and TVs. This system, known as the "Flowing Green Box," integrates energy storage, energy consumption, and energy management, significantly increasing the self-sufficiency rate of energy from 30% to 90%. Users can manage energy use in detail through the IOC screen built into the Green Box, monitoring energy consumption in real-time.

The implementation of this project has significantly reduced dependence on traditional energy sources while enhancing families' ability to cope with emergency situations such as extreme weather events and power outages. It is noteworthy that users can remotely set operating modes or monitor the device status through a mobile app, even when outside of the Green Box. Midea Group's photovoltaic thermal storage solution, developed based on this Green Box, has successfully entered overseas markets and created “iEasyEnergy APP”, a one-stop home energy management app, which is being promoted in over 40 countries worldwide.

“The Portable Green Box” is not just a revolutionary innovation in the building industry's energy usage patterns, it showcases the immense potential of combining green energy with intelligent management and brings new thoughts and directions to the sustainable development of future parks. Midea Group's building technology services cover the full life cycle from design and installation to operation and maintenance. This system can also transform into a mobile classroom, moving between rural schools, or become a creative station in the community, directly bringing the concept of green living to the public; or it could develop into part of a zero-carbon park, promoting the widespread adoption of ESG concepts internally within companies.

In the pursuit of “dual carbon” goals, the green transformation of industries with high energy consumption, such as the construction and manufacturing sectors, is crucial. The adoption of energy-saving equipment and the promotion of equipment upgrades are undoubtedly the focus of the market. The National Development and Reform Commission has set clear goals, with investment in equipment in key areas expected to grow by more than 25% by 2027 compared to 2023, and the energy efficiency of major energy-consuming equipment should reach advanced energy-saving levels. In active response to this trend, Midea Building Technology has launched the "Green Action Trade-in" program, aiming to provide subsidies for new equipment and special service support for newly signed renovation projects. Starting from May 1, 2024, participating companies will be able to enjoy up to 100,000/set of Al Smart Control free trial opportunities, as well as comprehensive support including pre-sales support, process services, and value-added services.

The great era of building energy-saving transformation has arrived, offering endless possibilities for promoting sustainable development in society.
