AccesS BIM file and real-time building measurements

This dataset contains building information and monitoring data collected within the AccesS project—Enhancing Accessibility and Sustainability in Smart Cities and Smart Buildings: The Universal Accessibility Suite Initiative. It covers a one-year monitoring period (2025–2026) and is based on measurements collected at the CERTH nZEB Smart House, which is used as a testbed. The monitoring data include indoor environmental conditions and building-level energy measurements. The data extend previously published datasets from the H2020 project D²EPC and are fully compatible with them, enabling unified analysis and further research. The following files are provided: i) The BIM-based data model of the smart home, provided in IFC format (.ifc file) ii) Building indoor and energy collected measurements during the period 2025–2026 (in separate .json files): Entire building: electrical energy consumption (lighting & appliances) Building PV installation: electrical energy production Living room: CO₂, temperature, humidity, luminance, presence, PM₂.₅, TVOCs, loudness Office: temperature, humidity, luminance, presence Technical infoInstalled sensors/meters: Entire building: Gavazzi 271 meter with public ID 1aa752e1-2797-4d10-b5fa-bbbaf0402927 Building PV installation: Fronius Symo inverter with public ID 1dcc86c8-1593-4b60-9e4a-513ddeb6f1d4 Living room: MCO Home A8-9 multisensor with public ID 7f3da9a1-cfaf-472e-b703-8a81775a5ac1 Office: Aeotec Multisensor 6 with public ID b1fa31e1-3658-466a-ba09-1a1fa4b954d0
