Decoding urban nature

Urban areas are home to millions of people who are exposed to the climatological conditions of their environment every day. To create sustainable living conditions, we help to minimize heat stress, air pollution and wind risk by providing up-to-date numerical simulation techniques.

and Thermal Comfort


Our vision

Passionate and driven by the desire to understand and simulate our environment as a holistic organism, we developed a microclimate simulation software that is based on objective scientific methods so that the effects of sustainable actions are measurable and evaluable.

Adapting cities for climate change

Thermal comfort is the key indicator to describe people´s subjective experience of temperature in urban open spaces.

Nature based solutions such as vegetation or water bodies can help in fighting urban heat stress and thermal discomfort.

The dynamic vegetation model analyses not only the effects of vegetation on microclimate but also tree health and damage risks due to strong winds.

The holistic approach can resolve the interactions between building physics and outdoor microclimate dynamically in both directions.


In the complex world of outdoor environments, climate parameters, vegetation, surfaces and structures constantly interact with each other. Due to the resulting interdependencies, these elements cannot be seen isolated. All interacting elements must be analysed even if only a single climatological aspect such as air temperature is required.

ENVI_MET is a software company with a service portfolio including cities & health, trees & vegetation, building & climate and wind & sun.

Passionate and driven by the desire to understand and simulate our environment as a holistic organism, we have the vision to prove the beneficial effects of architectural designs, Green and Blue technologies and landscape architecture.

We approach sustainability in architecture, urban planning and landscape design through numerical computer simulation using the latest techniques and methods in microclimate modelling and data analysis.

Our simulation system ENVI_MET is a holistic three-dimensional non-hydrostatic model for the simulation of surface-plant-air interactions not only limited to, but very often used to simulate urban environments and to asses the effects of green architecture visions. It is designed for microscale with a typical horizontal resolution from 0.5 to 5 metres and a typical period of 24 to 48 hours with a time step of 1 to 5 seconds. This resolution allows to analyse small-scale interactions between individual buildings, surfaces and plants.
