Trees & Vegetation

Sustainable Landscape Architecture

Green elements in the urban environment can buffer heat waves but are also exposed to hostile living conditions. The appropriate selection and composition of urban vegetation is therefore essential to create sustainable green spaces.

ENVI-met calculates the leaf temperature individually for each model grid box, taking into account the photosynthetic rate, water availability in the soil and the local evapotranspiration rate.

Detailed sinulation and analysis of the environmental conditions

One of the key benefits when implementing green solutions is the ability of vegetation to cool down the air temperature through shading, but also through evapotranspirative cooling. This process does not directly cool down the air, but first cools down the leaves, and then through heat transfer, cools down the air flowing through the foliage.

A cool leaf temperature is not only necessary to lower the air temperature. It can also stop the leaf tissue from being destroyed when the foliage temperature rises above a certain threshold. ENVI-met allows you to conduct detailed simulations to analyse the temperature impact of vegetation on the surrounding area as well as the impact of local climatic conditions on the vegetation itself.

By using ENVI-met it is also possible to focus on the demands of urban vegetation with consideration of wind stress and storm risk.

ENVI-met TreePass

Discover the needs of urban vegetation and support landscape architects in finding the optimal planting scheme: TreePass from ENVI-met is a comprehensive analysis tool for all microclimate growing conditions.

Sustainable and resilient landscape architecture does not only mean finding the best places to plant trees, but also identifying suitable species and establishing maintenance strategies to enhance tree survival in an urban environment.

TreePass for sustainable urban greenery

This new module will not only provide a comprehensive data sheet of all relevant growing conditions at prospective tree locations, but also look at the tree’s biomechanics to prevent storm damage.

TreePass will allow you to analyze individual trees at the scale of a typical crown geometry with the resolution of a single branch. The impact of the local growing conditions, such as access to light, as well as different maintenance strategies will be considered in the analysis. The risk of uprooting or breakage will be visible down to the individual branch level for an unlimited number of trees inside a city quarter.

The ENVI-met TreePass will consist of a number of analysis modules, the first of which will be available with the 2022 Release.
