Microclimate · Surface & energy · Wind · Daylight · Grid
CityDigitalTwin physically simulates how heat, wind, sun, building energy, and the power grid behave across a whole city — so architects, planners, and utilities can design cooler, healthier, more resilient places.
One platform, every scale
Most tools solve one slice of the urban climate problem. CityDigitalTwin couples them — microclimate, energy demand, and grid response in a single, physics-based model.
Heat-island mapping, air temperature, and thermal-comfort (UTCI) across every street and courtyard.
Heat · Humidity · RainWhole-city UBEM for heating, cooling, and HVAC loads — building by building, hour by hour.
UBEM · HVAC · LoadsPedestrian wind comfort and safety, ventilation corridors, and gust risk around towers.
CFD · PedestrianSolar radiation, daylight, and shadow studies to place mass, glazing, and green roofs precisely.
Radiation · DaylightBuilding-to-grid coupling: forecast demand, peak stress, and outage risk under climate extremes.
B2G · ForecastTrack emissions and size PV, vegetation, and green infrastructure against real climate data.

Import terrain, buildings, and materials, then run coupled climate and energy physics on GPU. Explore results as heat maps, isotherms, and building-level metrics you can actually design against.
How it works
A workflow built for early-stage decisions — when changing the design still costs nothing.
Drop in a site or a whole district. Buildings, terrain, vegetation, and materials become a simulation-ready model in minutes.
Couple microclimate, building energy, and grid response in one GPU run — no separate tools, no hand-offs.
Read the heat, comfort, energy, and cost impact of each option and share a report your stakeholders understand.
Case study
“PGL's CityDigitalTwin tool provides an accessible way for urban planners to understand development options in terms of microclimate effects.”
