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 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.
ENVI-met offers a detailed 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, which is only effective during the day, 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 but also keeps the leaf tissue from being destroyed when the foliage temperature rises above a certain threshold.
By using ENVI-met it is possible to focus on the demands of urban vegetation with respect to wind stress and storm risk. It can also calculate 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.
Discovering the needs of urban vegetation or supporting landscape architects in finding the optimal planting scheme: the ENVI_met TreePass is a comprehensive summary of all relevant microclimate growing conditions.
Sustainable and resilient landscape architecture does not only mean finding the best spots to plant trees, but also identifying suitable species and establishing maintenance strategies to enhance tree survivorship in an urban environment.
ENVI-met TreePass methodology gives plants and trees a central importance.
The 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.
The Tree Pass will be able to analyse individual trees on the level of the typical crown geometry with the resolution of a single branch using the idea of L-Systems. The impact of the local growing conditions, such as access to light, will be considered in the analysis as well as different maintenance strategies. The risk of uprooting or breakage will be visible down to the individual branch for an unlimited number of trees inside a city quarter.
The ENVI-met Tree Pass will consist of a number of analysis modules, the first of which will be available with the Spring 2022 Release.
