Headquarters Building of a Large State-Owned Gas Company [Digital Twin + Energy Management]

The integration of digital twin technology with smart buildings opens up broader possibilities for the development of intelligent architecture. Digital twin technology enables more accurate and comprehensive data acquisition, providing robust support for smart building systems. By leveraging digital twins, smart building systems can access real-time simulation data of the building, perform predictive analysis, and optimize operational strategies.For example, in equipment maintenance, smart building systems can use digital twin models to predict the lifespan and potential failure risks of devices, proactively notifying maintenance personnel for timely servicing and thereby reducing equipment failure rates. At the same time, the actual operating data of equipment can be fed back into the digital twin model, allowing verification and refinement of the model to enable dynamic interaction between the virtual and real systems.

In this project, the focus is on delivering a 3D digital twin platform and an energy information visualization system for the client’s headquarters building. The system is centered on energy monitoring and management, with enterprise operation and capability display as secondary functions. Internally, it supports building control, emergency energy response, and decision-making; externally, it caters to leadership receptions and visits from key clients.Through digital technologies, the platform effectively showcases the company's cultural values and corporate image. From a command perspective, the system integrates with external surveillance video feeds and project data to provide real-time interactive capabilities. In terms of energy analysis, it connects with business data systems to present analytical results and insights.

1. Overall Architecture

The system adopts a C/S (Client/Server) architecture for project development.

* Strong model loading capability enables more detailed and visually impressive scenes and rendering.

* Real-time rendering enhances user experience.

* Supports large-scale 3D urban scenes, offering powerful integration and visualization capabilities.

2. Headquarters Building

3D Scene: A digital twin 3D environment is constructed to showcase the building’s full appearance and general information.(Main building modeling includes detailed structure, refined UV mapping, texture creation, and realistic materials such as façade, internal structure, glass, and steel elements.)

Overview Data: Focused on presenting the building’s general profile and key operational metrics based on business requirements.

* General Introduction: A comprehensive overview of the building and its basic architectural information.

* Data Indicators: Display of integrated data supporting decision-making, including energy consumption statistics, alert information, equipment overview, environmental index data, etc. This allows for full situational awareness of the building and enables resource monitoring and management through a unified visual interface.

3. Interior Floor Modeling

3D Scene: Interior spatial modeling based on BIM models and CAD drawings, including elements such as floor slabs, wall layouts, and other structural components.

4. Underground Parking Lot

3D Parking Visualization: 3D representation of the spatial layout of parking levels and entry/exit points, including gate position mapping. Available and occupied parking spaces are distinguished by different status indicators, and EV charging station locations are clearly marked.

Access/Parking Data: Business-related data concerning vehicle access and parking activities.

5. Photovoltaic Equipment

3D modeling of photovoltaic panels along with a schematic illustration of the photovoltaic power generation process.

6. Energy Storage Equipment

Energy Storage Devices: 3D modeling of energy storage equipment based on CAD drawings and equipment specifications, including detailed exterior materials, textures, complex structures, internal components, and pipelines. The models also visualize the precise location mapping of equipment within the building.

7. Air Conditioning Equipment

HVAC Equipment: 3D modeling of air conditioning units inside the building, featuring detailed exterior materials, textures, complex structures, internal components, and piping. The system visualizes the exact location mapping of these devices within the building.

8. Power Equipment

3D Scene: Creation of 3D models for the power modules and their locations within the main project building, along with interior floor modeling.

Electricity Data: Energy metering points and power consumption indicators.

* By integrating with meter data, the system enables real-time monitoring and statistics of overall energy consumption across the campus, promptly detecting abnormal energy usage. It supports monitoring of power consumption at floor and area levels, providing real-time and historical consumption dashboards and summaries.

* Energy consumption data is visualized per floor, using charts within the 3D scene to display both current and historical power usage.
