Research project decarbonization of construction site logistics and processes

Monitoring is used to record emissions at the construction site and allocate them as precisely as possible to the various construction processes in order to investigate decarbonization options for construction sites using life cycle assessment methods. This should enable housing companies in Germany to transparently reduce their emissions during construction.

On its WA 1 Mitte construction site, GWG Städtische Wohnungsgesellschaft München mbH, together with the Chair of Timber Construction and Building Construction at the Technical University of Munich, the Federal Association of the German Brick and Tile Industry and the Holzbau Deutschland Institut, is investigating how construction processes and logistics can be decarbonized on the construction site. One building in timber construction and one in solid construction will be put under the microscope. The results will later provide the basis for a catalog of criteria for the ecological awarding of construction contracts. In this way, housing companies in Germany will be able to transparently reduce their emissions during construction. Together with the Technical University of Munich, GWG München is measuring emissions from the delivery of materials and machinery to the operation of equipment at the construction site on Christel-Sembach-Krone-Strasse in Freiham. The data is collected sorted by trades and components. Through the results, emissions from the construction site are recorded and assigned as accurately as possible to the various erection processes. In addition, an analysis of the potential for decarbonization of erection processes at the participating shell construction companies and in project planning and control is being investigated. The project is funded by the Deutsche Bundesstiftung Umwelt (German Federal Environmental Foundation) and is scheduled to run for a total of 18 months (March 2022 to September 2023).
