CityDigitalTwin
The Urban Microclimate, Building Energy, and Grid Simulation Platform

Design, simulate, and optimize urban microclimates, building energy, and power grids.
Empowering architects, planners, cities, and utilities to create cooler, healthier, and more sustainable cities.

Creating Climate-Smart Cities Through Advanced Microclimate, Building Energy, and Building-to-Grid Integration Technology

Green Urban Area

Transform cities with precision microclimate, building energy, and grid integration analysis. Our industry-leading simulation platform empowers architects, planners, developers, and utilities to create sustainable, energy-efficient spaces and resilient grid systems—backed by real-time environmental and operational data.

Building-to-Grid Integration for Resilient Cities

Predict, simulate, and optimize urban energy use under real-world conditions

Our platform now connects detailed building energy modeling with grid simulation tools—empowering cities, planners, and utilities to analyze how extreme weather events and demand fluctuations impact energy systems at scale.

​

Use scenario-based simulations to test thermostat strategies, pre-heating or pre-cooling measures, and demand-side flexibility across thousands of buildings. Support proactive grid management, avoid blackouts, and plan for a more resilient, low-carbon future.

“PGL’s CityDigitalTwin tool provides an accessible way for urban planners to understand development options in terms of microclimate effects.  Planning for outdoor thermal comfort is limited by the lack of practical tools.  PGL’s tool overcomes this problem and allows planners to evaluate the effectiveness of the full range of cooling strategies without being microclimate modelers.  As our climate continues to heat up, this capacity will become increasingly essential for planners.”
