Post City Linz - Biodiversity in the CO2-neutral urban quarter
Starting April 2022
Starting point / motivation
Since the closedown of the postal distribution center in 2014, the area close to the main train station in Linz has lost its traditional function. It is now being developed into a quarter with a gross floor area of over 150,000 m2.
In the course of the planned rededication, a two-stage EU-wide open general planning competition was launched in 2019, which was won by Nussmüller Architekten ZT GmbH. The goal is to create a multifunctional quarter with offices, apartments, stores, restaurants and other uses.
In several phases, the new "Post City Linz" consisting of 11 high-rise buildings is to be built over the next few years. Due to its central location, the "Post City Linz" offers excellent conditions for the development of an innovative energy- and resource-saving quarter.
Contents and goals
The set goals as well as the innovation content result from the examination of the feasibility of an energetically and urban-climatically ambitious quarter concept and corresponding definition of implementation measures.
The findings obtained from the exploratory study form the basis for ongoing planning and implementation and are expected to reveal generally applicable findings for the transformation of inner-city industrial and commercial areas toward resilient energy- and resource-saving quarters.
The focus of the investigation lies on a package of measures as part of a systematic and coordinated approach: support of biodiversity by "animal aided design" of building envelopes, a CO2 neutral energy supply and innovative energy management in the quarter, as well as rainwater management based on the principle of the "sponge city". Basing on this approach, innovative green structures will be planned and evaluated regarding urban heat islands as well as quality of sojourn and energy and resource saving potentials.
The results of the exploratory study include efficient urban greening technologies to support natural cooling effects (e.g. evaporation processes, integration from the area of albedo, thermal insulation effect, microclimate) as well as detailed concepts for a CO2 neutral energy supply and energetic building optimization, and lead to significant improvement in the quality of life. In addition, façade solutions that promote biodiversity in the quarter will be developed.
The processing and connection of different technologies (biodiversity, animal aided design, sponge city concept, energy management concept, life cycle consideration, etc.) is illustrated by means of a catalog of measures as well as recommendations for action, taking into account the architectural quality.
The findings from the study form the basis for the ongoing planning and implementation of the project also named "Post City Gardens" and are intended to provide generally valid findings for the transformation of inner-city industrial and commercial areas towards resilient energy- and resource-saving neighborhoods.
