August 15 is National Ecological Day, China’s first national holiday dedicated to the theme of “ecology.” It is both symbolic and unique. The establishment of this holiday underscores the growing recognition and attention that the term “ecology” is receiving at both the national and societal levels, and it also reflects the comprehensive and diversified achievements made in China’s ecological civilization building.

　　Put the philosophy of "Lucid waters and lush mountains are invaluable assets" into practice and advance ecological civilization building.

　　The natural ecological environment is both the fundamental condition for human survival and development, and the source of social progress and material advancement. As the global population grows and industrialization continues to advance, the Earth’s environment has been steadily deteriorating, severely disrupting and damaging the natural ecological balance. Issues such as dwindling resources and declining biodiversity have become irreversible. Once this balance is disrupted, it will trigger a cascade of butterfly effects, ultimately and profoundly impacting humanity itself. Therefore, safeguarding the ecological environment—a matter that is fundamentally linked to the sustainable development of both humanity and society—is now a global focal point of concern.

　　Compared with developed countries, China still has a significant gap in terms of resource utilization efficiency and green technology innovation. Issues such as low resource utilization rates, high energy consumption, and low recycling rates are widespread. Moreover, the research and development and application of green technologies still fall short of meeting the demands of green development.

　　Since the 18th National Congress of the Communist Party of China, our country has consistently emphasized that ecological civilization construction is a fundamental strategy crucial to the sustainable development of the Chinese nation. Protecting the ecological environment means protecting productive forces, and improving the ecological environment means developing productive forces. We will never sacrifice the environment for short-term economic growth. The concept that "lucid waters and lush mountains are invaluable assets" has become a shared consensus and a common course of action across society. Green development has become the underlying tone of China's modernization drive and a widely held conviction among the general public.

　　Currently, China’s economic and social development has entered a stage of high-quality growth characterized by accelerated greening and decarbonization. High-level environmental protection is a crucial support for high-quality development, and high-quality development can only be achieved through high-level environmental protection. We must always plan our development from the perspective of harmonious coexistence between humanity and nature. By pursuing high-level environmental protection, we can continuously foster new drivers and new advantages for development, and steadily enhance our development potential and long-term momentum.

　　As we enter a critical phase, the establishment of “National Ecological Day” is not merely a symbolic milestone—it is also a powerful driving force that will enhance the public’s awareness and proactive engagement in ecological and environmental protection, fostering a broad-based approach to ecological civilization construction in which all sectors of society participate and act together. This initiative holds significant practical and profound historical implications for accelerating the establishment and improvement of a green, low-carbon, and circular economic system, promoting industrial transformation and upgrading as well as high-quality development, and advancing the process of Chinese-style modernization.

　　Green development is a long and arduous journey; we must pool our efforts to tackle energy conservation and carbon reduction.

　　Since China clearly articulated its “dual-carbon” goals in 2020, “dual-carbon” has become a key term in economic and social development. In recent years, emerging green and low-carbon technologies have been iterating at an unprecedented pace, serving as the core driving force behind the green and low-carbon transformation across all industries. The energy-saving benefits brought by cutting-edge, ultra-high-efficiency equipment and ultra-low-energy-consumption buildings—among other green technologies—are now visible everywhere in our daily lives.

　　In this great test of our times, the question we face is how to seize the opportunities presented by change and steadily advance on the path of green development.

　　Although buildings may appear to be merely a combination of bricks, cement, and reinforcing steel, their internal operating systems are remarkably complex—taking into account factors such as airflow and lighting design—and consume enormous amounts of energy. According to the “Research Report on the Development of High-Efficiency Air-Conditioning and Chiller Rooms in China,” building energy consumption accounts for approximately 30% of total societal energy consumption, making buildings major contributors to carbon emissions.

　　Current solutions for building energy conservation primarily include improving the building envelope, adopting energy-efficient equipment, implementing intelligent control and management technologies, applying energy-saving architectural design principles, and fostering energy-conservation awareness. However, in achieving overall energy savings, many challenges and obstacles remain, particularly in enhancing the energy efficiency of building cooling systems.

　　In fact, the largest component of a building’s energy consumption is its air-conditioning and cooling system. The cooling system accounts for “half of the building’s energy consumption,” reaching as high as 50%. Moreover, electricity consumption for cooling alone makes up more than 15% of the nation’s total electricity usage, with an average annual growth rate as high as 20%.

　　The energy efficiency of building cooling systems worldwide is generally low. Currently, the average Seasonal Coefficient of Performance (SCOP) for cooling systems in China stands at 3.6, while in the United States it averages 4.0. Faced with pressing and significant challenges, people often focus solely on the energy efficiency of air-conditioning equipment itself, neglecting the energy-saving potential of other aspects of the system. Among them, one company has adopted a holistic approach—from the perspective of the entire industrial chain—to develop system solutions that offer "lower lifecycle costs."

　　After thoroughly considering the application scenarios, operational management practices, and business model characteristics of industry clients, Nanjing Tianjia R&D has launched a full-lifecycle energy-saving solution. By leveraging data modeling and deep-learning algorithms, this solution achieves “true energy savings with full-process traceability.” Utilizing advanced technologies such as big data, cloud computing, and artificial intelligence, this solution is more intelligent and can proactively optimize energy consumption. As a result, this full-lifecycle energy-saving solution offers significant advantages in achieving sustainable building energy efficiency, while also possessing tremendous market potential and broad applicability.

　　Delivering “practical measures” to enhance quality and efficiency, leading the way toward a green and low-carbon future.

　　As Chinese enterprises grow—especially as our industrial scale evolves from weak to strong and shifts from merely pursuing survival to building century-old brands—along with the enhancement of corporate capabilities, their social responsibility is also on the rise. As a leading brand in China’s central air-conditioning industry, Tianjia always keeps its corporate social responsibility and social value firmly in mind.

　　Tianjia is deepening its engagement in the field of building energy efficiency, aligning seamlessly with the “dual carbon” goals. In 2021, among 135 submitted projects, Tianjia stood out and won the annual grand prize in the Green Innovation category of the 2021 Paulson Prize for its “Integrated Energy Efficiency Enhancement and Innovative Investment Model for Building Cooling Systems.” The Paulson Prize is a highly prestigious award in the global green and environmental protection industry.

　　Achieving the “dual carbon” goals represents a broad and profound transformation. In promoting energy conservation and emission reduction, we must adopt systems thinking, strike a proper balance between emission reduction and development, and accelerate the establishment of industrial structures, production methods, lifestyles, and spatial patterns that conserve resources and protect the environment.

　　The “lower lifecycle cost” solution is Tianjia’s “flagship achievement.” This solution introduces a multi-party, real-time supervision and monitoring system involving Tianjia, the user, third-party authoritative monitoring agencies, Party A, and the design institute. It uses the lifecycle cost of system products as a “measuring stick” for energy-saving performance, significantly reducing lifecycle costs while achieving energy savings of up to 50%—a reduction of half compared to conventional approaches.

　　For many years, Tianjia has not only continuously advanced the research and development of green innovation technologies but has also placed great emphasis on the implementation of green manufacturing practices. The company has actively been building smart factories with fully automated, end-to-end management systems, leveraging cutting-edge digital technologies and equipment to achieve automation, informationization, and intelligentization of the production process. Following digital transformation, Tianjia’s factory has seen a 42% increase in manufacturing efficiency while reducing energy consumption by 18%. The emergence of smart factories and smart logistics has not only boosted production efficiency but has also enabled better control over energy consumption and carbon emissions throughout the production process.

　　“When plants and trees thrive, the nation prospers.” Achieving green and low-carbon development has become a broad consensus within the international community—and it is also an intrinsic requirement for our country as we advance ecological civilization and strive for common prosperity. Today, Tianjia has evolved into an energy-efficient enterprise that meets the demands of the times, providing stronger support for enterprises’ sustainable development on the path to energy conservation and consumption reduction. The author firmly believes that Tianjia, with its unwavering commitment to energy conservation, environmental protection, and quality standards, will surely carve out a brilliant future in an ever-changing market.
