How Future Buildings Achieve Green Goals Transformation?

Against the urgent backdrop of global climate change, the construction industry is undergoing a "low-carbon revolution." The recently released "2024 White Paper on Technological Innovation and Development of Low-Carbon Smart Buildings" points out that green and intelligent buildings will become the core direction of the industry's transformation—integrating low-carbon technologies and intelligent management, leveraging the Internet of Things, AI, big data, and other means to reduce energy consumption, improve efficiency, and ultimately contribute to the achievement of "dual carbon" goals.

 

Three Core Drivers of Building Transformation

1. Low-Carbonization : Reducing greenhouse gas emissions and promoting the application of renewable energy.
2. Intelligence : Optimizing operation and maintenance management using technologies such as the Internet of Things and digital twins.
3. High Efficiency : Improving energy utilization efficiency through data analysis and intelligent algorithms.

 

Current Challenges: The Gap Between Ideal and Reality

Although the technological prospects are broad, implementation still faces multiple bottlenecks. ：

1. Technology-related : Poor system compatibility, difficulties in data acquisition, and high cybersecurity risks.

2. Policy-related : Non-uniform carbon emission accounting standards and insufficient support from green finance.

3. Market-related : Long investment return periods, single business models, and a shortage of professional talent.

 

Three Technological Pillars of Low-Carbon Smart Buildings

1. Internet of Things (IoT)—The "Nervous System" of Buildings

①Data Acquisition : Real-time monitoring of building status through 5000+ sensor nodes (such as temperature and humidity, CO ₂ concentration, and electricity consumption);

②Remote Control : Air conditioning, lighting, and other equipment can be automatically adjusted according to the density of people, reducing energy consumption by 15%-20%;

③Case Study : A smart park in Shanghai uses IoT to achieve "minute-level" energy consumption anomaly warnings, saving over 2 million yuan in electricity costs annually.

2. Digital Twin—The "Virtual Mirror" of Buildings

①Technical Principles : Based on BIM (Building Information Modeling) and real-time data, a virtual model is created that maps to the physical building 1:1;

②Fault Prediction : By simulating equipment wear and tear trends, it provides a 3-month advance warning of central air conditioning compressor failures;

③Energy Efficiency Optimization : Adjusting the operation strategy of the ventilation system reduces summer air conditioning energy consumption by 22% in a certain office building.

3. Energy Microgrid—The "Self-Sufficient Ecosystem" of Buildings

①Photovoltaic Power Generation : Rooftop photovoltaic panels generate an average of 3000 kWh per day;

②Energy Storage System : Cascade utilization of battery energy storage, charging during off-peak hours and discharging during peak hours, increasing annual revenue by 18%;

③Flexible Power Consumption : Dynamic scheduling of charging piles, elevators, and other loads through AI algorithms, significantly improving peak-shaving and valley-filling effects.

④Benchmark Case : A "photovoltaic storage direct flexible" demonstration project in Shenzhen achieves 100% green energy self-sufficiency and zero carbon emissions.

 

How Government, Enterprises, Academia, and Research Institutions Can Work Together ？

1. Policy Support : Accelerate the formulation of carbon accounting standards and increase subsidies for green finance.

2. Technological Breakthroughs : Industry-academia-research cooperation to break through "bottleneck" technologies, such as system integration and data security.

3. Market Cultivation: Promote demonstration projects and create replicable business models.

4. Talent Reserves : Universities add interdisciplinary programs to cultivate compound talents who "understand technology and can manage".

 

 

Conclusion

Transformation has no way out, but the future is full of hope.

 

China's practice of low-carbon smart buildings has taken a key step. However, this transformation is not only a contest of technology, but also the co-evolution of policy, market, and society. As the white paper states: "The future of buildings is not on blueprints, but in the intelligent control of every switch, the energy conversion of every photovoltaic panel, and the precise analysis of every piece of data."
