The dataset consists of measured values from all the energy meters installed in Nanogune building located in San Sebastian (Spain). These meters differentiate between the electricity consumption of the intensive production equipment (chillers, clean room, laboratories, etc.) and the one related to the rest of the installation (offices, lighting, common areas, etc.). They also reflect the thermal consumption data (cold and heat) of each area of Nanogune building. There are 79 meters in total: 58 of them are electric meters, 20 thermal meters (10 cold, 10 heat) and a gas meter. All the meters have a time step of 15 minutes, and the data set covers a period of 5 months. The data set contains - Timeseries as CSV files - Timeseries metadata (description, unit, type,...) as JSON file The data have been made available from the BMS database, thanks to the BEMServer open-source platform - www.bemserver.org, developed in the HIT2GAP project that has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement n. 680708 - www.hit2gap.eu.
