This is the dataset accompanying the PhD thesis: N. Voulis. Harnessing Heterogeneity - Understanding Urban Demand to Support the Energy Transition. PhD Thesis. Delft University of Technology. 2019. https://doi.org/10.4233/uuid:9b121e9b-bfa0-49e6-a600-5db0fbfa904e. Real urban areas consist of a mix of households, services (such as schools, offices, shops, etc.), and industry. However, most literature concerned with local energy demand simplifies it to household demand only. This is, to a large extent, cause by a lack of detailed (e.g., hourly) service sector and urban-scale energy demand data. This dataset and the accompanying thesis seek to resolve this issue. The primary focus of this dataset and the accompanying thesis is therefore on service sector and urban-scale demand data. Households are also taken into account, albeit in less detail. Households and services are often collocated in urban areas, but extensive research and data already exist for households. Industry is left out of scope. The dataset contains: - …
