PART 1Executive Overview
1Definition

Real-time City Digital Twins are live virtual replicas of a city's physical and functional characteristics, including its infrastructure, environment, and systems. These digital twins are synchronized in real time using Internet of Things (IoT) sensors to capture current conditions and behaviors.

2Problem It Solves

Optimizing urban planning, resource management, and emergency response by providing a comprehensive, real-time view of the city’s infrastructure and systems.

PART 2Technical & Manufacturing
4How It Works

BIM data is integrated with real-time data streams from IoT sensors monitoring traffic flow, weather patterns, energy usage, and other environmental factors. This integration allows for a dynamic, up-to-date representation of the city's state that can be analyzed and simulated in real time.

5Materials Used
6Manufacturing / Creation Process

The core technology involves software development for data integration, sensor networks, and simulation models. Manufacturing is primarily focused on developing and deploying IoT sensors and integrating them with existing BIM systems.

7Build Process

Developing the digital twin involves collecting BIM data, setting up real-time data feeds from various sources (traffic, weather, energy), and creating a software platform to integrate these data streams into a cohesive model. Continuous updates are necessary as new data becomes available.

8Energy Requirements

Field units draw low hundreds of watts; fabrication is energy-intensive due to vacuum baking. Sensor networks require minimal power but depend on the number and type of sensors deployed.
