we cordially invite everybody interested to our next open GIScience colloquium talk
“Heatmapping”: Accessing Geodatabases of Building Stocks for the Development of Spatial Energy System Models
Sebastian Blömer
ifeu Institut für Energie- und Umweltforschung Heidelberg
Time and date: Mon, July 10, 2.15 pm
Venue: INF 348, Room 015, Department of Geography, Heidelberg University
To evaluate the technological and economic feasibility of the use of different heat sources, conversion and supply structures, the development of high-resoluted GIS-Models of the long term energy demand for floor heating and hot water in residential and non-residential buildings became an important field of research in recent years. In this talk, I will give an overview of spatial energy system models of the German building stock from my work at the ifeu – Institute for Energy and Environmental Research Heidelberg. First, I will present the main requirements of spatial heat demand models of buildings with regard to the leading research questions and set them in relation with available geodatabases. As an insight into the development of nationwide heat atlases, I will present the procedure of a nationwide GIS-model of the development of the long term heat demand in the German residential building stock based on proprietary building footprint data. I will conclude with an overview of my recent work on integrating 3D-data and information on non-residential buildings into GIS-based heat demand models. As an Input for discussion, I will present the results of an evaluation of different machine learning algorithms for the automatic classification of settlement structures to enrich building footprint data.
