Hamburg Building Typology

Detailed GIS Based Building Stock Analysis and Typology for Hamburg

Hamburg, the European Green Capital 2011, has ambitious climate targets for 2020 and 2050. Buildings – residential and non-residential – are set to play a major role in their carbon reduction strategy. But sound political decisions must be based on reliable information about Hamburg’s building stock. Until recently there was no up-to-date information on the number of heated areas in the different types and vintages of buildings in Hamburg.

Hamburg, the European Green Capital 2011, has ambitious climate targets for 2020 and 2050. Buildings – residential and non-residential – are set to play a major role in their carbon reduction strategy. But sound political decisions must be based on reliable information about Hamburg’s building stock. Until recently there was no up-to-date information on the number of  heated areas in the different types and vintages of buildings in Hamburg.

Ecofys has elaborated a new building typology for Hamburg. Complex evaluation and processing of data from numerous sources led to a classification of residential buildings in 48 types (6 geometry classes, 8 age classes) and of non-residential buildings to 40 types (10 geometry classes, 4 age classes). Hamburg’s Geographical Information System (GIS) was used as a major tool, data source and sink for new information generated by Ecofys. Ecofys was then able to assign a building type to more than 90% of the relevant buildings in the GIS. For every building type a data sheet was produced, providing individual information on typical characteristics like geometry, total treated floor area in Hamburg, energy demand, energy consumption, used energy mix and estimated state of modernisation.

The results will serve Hamburg as a major database for adding new data, determining priority areas for energetic renovation, estimating  realistic energy and carbon saving potentials, related costs and benefits and strategic decisions on the future heat supply. All new information has been delivered as new part of the Hamburg GIS which is used for urban planning. Alongside having the information in a directly applicable data format, the first useful information on  very large non-residential building stock has been provided.
