From Data to ESG Value: Schneider KNX Empowers Full-Link Energy Visualization in National Energy Storage Building

As a benchmark building integrating energy storage technology demonstration, office operation, and technological research and development, the National Energy Storage Building focuses on core demands including efficient energy dispatch, full-process energy-saving management and control, traceable ESG data, and sustainable operation. With its powerful logical control capability and multi-device compatibility, the Schneider KNX system is deeply integrated into the building's energy storage system and building operation and maintenance system, constructing an intelligent management and control platform centered on Smart Energy Management. Through energy visualization and precise linkage control, it achieves quantitative reduction of energy consumption and the realization of ESG goals, setting a model for the integration of energy storage buildings and smart buildings.

As the core carrier of the building's energy management and control, the KNX system breaks down data barriers between energy storage units, power distribution circuits, and building equipment (lighting, HVAC, sunshades). Through logical programming, it realizes full-link coordination of energy "generation-storage-consumption", accurately matches energy storage discharge with building energy demand, and constructs a dynamically balanced energy management system.

Relying on the open KNX protocol and logical control capability, it links the building's energy storage EMS system with terminal equipment to realize intelligent adaptation between energy storage status and building energy consumption—prioritizing the use of stored energy to power loads during peak hours (high electricity prices) and linking energy storage charging with optimized low-load operation of equipment during off-peak hours (low electricity prices), maximizing the energy-saving value of energy storage.

Through full-dimensional energy data collection and visual presentation, it accurately counts energy consumption and carbon emission data of each area and equipment, providing traceable and quantifiable core basis for the building's ESG report and helping to achieve green building certification and sustainable operation goals.

Based on KNX zonal control and scenario linkage logic, combined with multi-dimensional data such as illumination, personnel, and electricity prices, it automatically optimizes equipment operation strategies, reduces core energy consumption of lighting, HVAC, etc., from the source, and practices the concept of Sustainability.

1. Peak-Valley Electricity Price Adaptation Logic: Through programming of the KNX logic module, it links power metering equipment and energy storage systems, and sets peak-valley electricity price linkage rules. During peak hours (high electricity prices), it automatically switches to energy storage discharge mode, prioritizing power supply for lighting, office equipment, air conditioners and other loads to reduce the proportion of grid electricity consumption; during off-peak hours (low electricity prices), it switches to energy storage charging mode, while reducing the operation load of non-essential equipment and only maintaining the operation of basic guarantee equipment, achieving a reduction of more than 30% in electricity costs.

2. Energy Storage Status Linkage Logic: When the energy storage unit's power is ≥80%, the KNX system automatically increases the operation load of building equipment (such as full-load cooling/heating of air conditioners and full activation of public area lighting) to consume redundant stored energy; when the energy storage power is ≤20%, it immediately links equipment to switch to energy-saving mode, shuts down non-core circuits, and prioritizes ensuring energy supply for core office areas to avoid over-discharge of energy storage.

1. Office Areas: Human Body Sensing + Natural Light Linkage Control: Through the linkage of KNX human body sensors and light sensors, it realizes the basic logic of "lights on when people are present, lights off when people leave". At the same time, it automatically adjusts lighting brightness according to natural light intensity (constant illuminance control at 500lx standard) to avoid glare waste. Combined with the energy storage power supply status, it prioritizes the use of stored energy during office hours and automatically cuts off the power supply of regional circuits during non-office hours. The lighting energy consumption in this area is reduced by 35%, and HVAC energy consumption is reduced by 30%.

Relying on Schneider KNX energy monitoring modules and a central management and control platform, a multi-level energy visualization system is constructed to achieve three core functions:

1. Real-Time Data Monitoring: Split energy consumption data by area (office areas, equipment rooms, public areas) and equipment type (lighting, HVAC, energy storage loads), display real-time parameters such as voltage, current, power, and total energy consumption, support hourly, daily, and monthly data statistics, and accurately locate high-energy-consumption links.

2. Quantitative Carbon Emission Analysis: Automatically convert carbon emissions based on energy consumption data, generate carbon emission trend reports, intuitively present carbon reduction effects brought by energy-saving measures, and provide quantitative data support for ESG reports (annual carbon emissions reduced by more than 25%).

3. Fault Early Warning and Optimization Suggestions: When energy consumption in a certain area exceeds the standard abnormally (deviating from the baseline by 20%), the system automatically triggers an alarm and pushes it to the operation and maintenance terminal, and provides optimization suggestions based on historical data (such as adjusting equipment operation time, inspecting aging circuits) to support refined operation and maintenance.

1. Full-Energy Monitoring Module: Schneider METSEPM3200, with an accuracy class of 0.5S, supports full-parameter collection including three-phase voltage, current, power, harmonics (up to the 15th order), and energy metering. It uploads data to the KNX bus in real time, providing accurate data support for energy visualization and carbon emission calculation.

2. Energy Management Gateway: Schneider MTN680329 (KNX/IP Gateway), realizing interconnection between the KNX bus, Ethernet, and energy storage EMS system, ensuring stable transmission of energy consumption data and control commands, and supporting data synchronization of the central visualization platform.

1. Intelligent Logic Module: Schneider MTN676090, as the core logical control unit, supports complex logical programming such as peak-valley electricity price linkage, energy storage status adaptation, and scenario mode switching, realizing coordinated operation of multiple devices and serving as the core hardware for Smart Energy Management.

2. Universal Switch/Dimming Modules: Schneider MTN6710-0102 (universal dimming main module) and MTN649315 (4-channel dimming actuator), used for precise dimming and switch control of lighting in office areas and public areas, adapting to constant illuminance control logic and supporting linkage adjustment with energy storage power supply status.

1. Multi-Parameter Sensor: Schneider MT005-0001 (KNX temperature, humidity, CO₂, and human presence sensor), integrating multi-dimensional detection functions of human presence, illumination, temperature, and humidity, providing environmental data input for linkage control in office areas; matched withMTN6725-0005 (DALI Gateway) to realize seamless linkage between the lighting system and sensors.

2. HVAC Control Module: Schneider MTN6730-0002 (6-channel heating/cooling actuator), precisely adjusting the operation status of air conditioners and ventilation equipment, linking equipment room temperature and humidity data with energy storage load to optimize HVAC system energy consumption.

3. Bus Power Supply and Connectors: Schneider MT940-0000 (main module expansion connector) and MT941-0002 (expansion connection cable), ensuring stable power supply of the KNX bus and equipment expansion, adapting to the large-scale wiring and multi-device access needs of the building.

Through KNX logical control and energy storage coordination strategies, the overall energy consumption of the building is reduced by 25%-30%: among them, lighting system energy consumption is reduced by 35% due to constant illuminance and time-sharing control, HVAC system energy consumption is reduced by 30% due to linkage adjustment, and equipment room energy consumption is reduced by 18% due to environmental linkage control, far exceeding the energy-saving level of traditional buildings, with annual electricity cost savings exceeding one million yuan.

The energy visualization platform realizes "transparent and traceable" energy consumption data. The operation and maintenance team can grasp the entire building's energy status through remote monitoring, shortening the fault response time by 60%; automated linkage control reduces manual intervention, lowering operation and maintenance workload by 40%, achieving the dual goals of "refined operation and maintenance + cost reduction and efficiency improvement".

The quantitative energy consumption and carbon emission data generated by the system provide core support for the building's ESG report, with annual carbon emissions reduced by more than 25%, helping to achieve LEED Gold certification standards. The coordinated mode of energy storage and building energy consumption provides a sustainable solution of "energy storage + smart building" for the industry, practicing the dual carbon goals.

The modular design and open protocol of the Schneider KNX system support the later expansion of energy storage units and the access of AI energy optimization algorithms without reconstructing the bus system; it is compatible with new IoT monitoring terminals, reserving sufficient space for the upgrading of Smart Energy Management and adapting to the needs of energy storage technology iteration and building function expansion.

In the National Energy Storage Building project, the Schneider KNX system, with logical control as the core, is deeply integrated with energy storage technology and building operation and maintenance. Through Smart Energy Management strategies, full-link energy visualization, and precise linkage control, it not only achieves a quantitative energy-saving effect of 25%-30% but also constructs a traceable and quantifiable ESG management system, perfectly practicing the concept of Sustainability. The precise selection of Schneider KNX equipment ensures system stability and compatibility, and its coordinated "energy storage - building - energy" mode provides replicable practical experience for the intelligent and green operation of energy storage buildings, highlighting the core value of the KNX system in high-end energy storage buildings.
