IFLA Europe Exhibition ‘Reconsidering Nature’ - Second Project from OGLA AUSTRIA: “The Climate Resilient Redesign of Johann-Nepomuk Vogl Platz

After the great success of our first Exhibition ‘Landscape as a Common Ground’, IFLA Europe has organised the second edition entitled ‘Reconsidering Nature’.


The aim of the exhibition is to show the contemporary role of landscape architects in creating space. Its conventionally perceived task - to create and preserve beauty in the surrounding of human habitations - has expanded considerably. Environmental challenges, climate change and the living conditions of the inhabitants of larger and larger cities oblige us to take nature beyond the emphasis on aesthetic perspectives. In design, planning and management of landscapes, landscape architects face a contemporary challenge: thinking of nature as a subject, understanding its principles and respecting its needs

IFLA Europe exhibition will present projects conceived and created in close connection with the nature. It will include large and small-scale implemented landscape architecture projects showing the forces of nature as well as exposing nature’s rights, role and importance.IFLA Europe exhibition will present an overview of realised landscape architecture projects from all over Europe which are realised in harmony with the nature and using nature-based solutions. Implemented projects will show work of landscape architects working either individually or in multidisciplinary teams. Realised projects will promote environmental as well as aesthetic value

This week we would like to present a project from OGLA AUSTRIA entitled “The Climate Resilient Redesign of Johann-Nepomuk Vogl Platz”!

The Sponge City Principle for Trees City squares of the future should improve the quality of stay in public space and must be designed for climate-resilience. The redesign of Johann-Nepomuk-Vogl-Platz addressed this challenge. The square is situated in a densely built-up part of Vienna’s 18th district. A market area with food stalls surrounds a central plaza with an impervious surface, seating, old and newly planted trees and a playground. To create a pleasant micro-climate shade and evaporation by trees are needed. Thias requires healthy and well-developed trees and sufficient moisture in ground for the trees to evaporate. The sponge city principle for trees provides a nature-based solution for growing trees in impervious surfaces. The stormwater management was designed to collect the roof runoff from the market stalls and all surface waters from the square. A splash pad on the plaza is fed with drinking water for hygienic reasons, the runoff irrigates the trees. Discharge into the sewer is reduced to zero. Six newly planted trees on the plaza are provided with an extended root space of 35 m³ per tree. The substrate consists of coarse aggregate for load bearing and washed-in fines for water and nutrient storage. The retained water is available for evaporation by the trees, the surplus infiltrates into the subsoil. The sponge city principle for trees proves to be a functioning method for combining stormwater management, climate change adaptation and quality of stay through green infrastructure in streets and urban spaces in a multifunctional way.

The author of the project is Karl Grimm Landschaftsarchitekten.
