Abstract

Abstract Body

The German Federal Government has defined high climate protection targets for the building sector up to 2050 and beyond. The municipal authorities and local government play an essential role in implementing this process. They have a significant direct impact on the regional urban development of climate protection and climate adaptation through active action.

The built environment can be a key element of municipal climate protection. In the future, the use of sustainable biobased materials and renewable energy systems will play a significant role in this context. Timber constructions in particular, which are designed for durability and reusability, are able to enhance the reduction of carbon dioxide emissions in municipalities. Biobased products offer two environmental benefits: the storage of carbon in the material and the additional substitution effect when mineral construction is replaced by timber structures. However, municipal decision makers are usually unaware of these potentials because they are not part of the urban landscape planning. This is where the geodata-based web-GIS system "Holzbau-GIS" comes in.

The aim of the R&D project "Holzbau-GIS" is to demonstrate the potential of utilizing wooden building materials as an additional climate protection method for municipalities and to make this nature-based solution practicable.

In this paper, besides the methods and model description to calculate the carbon dioxide emission savings, first impressions on the web-GIS-system are presented. The web-GIS system integrates the available geodata on the building level and puts them into a citywide context. In different scenarios, feasible potentials for new construction or modernization can be projected. In addition, the results are divided into the carbon storage in the wooden material and the substitution potential by replacing mineral constructions with wooden structures.

The results show greenhouse gas savings from timber utilization as well as its potential as additional municipal climate protection. The web-GIS system supports municipal decision-makers in their decision-making process in the context of urban landscape planning. Based on this, they are able to quantify these possibilities through the project "Holzbau-GIS".
