Describes the immediate built environment of a participant’s address and indoor qualities of a participant’s home. Built environment (be) variables measure the geometry of the building and block containing the participants address. Indoor qualities (iq) variables uses Energy Performance Certificate (EPC) data to measure the properties energy use/efficiency and to describe the internal layout and features of the property.
Usage instructions: To link to BiB4All participants, use the property_id variable to link to bib4all_geog_person.
Further information: Created by Kimon Krenz, on behalf of BiB. Please reference Krenz et al. (2023) when using this data, where more detailed methodological information can be found regarding the construction of these variables.
