Motivation

Many energy certificates for public buildings are currently being published as part of the "Klimacheck" campaign (https://fragdenstaat.de/kampagnen/klimacheck/). I would like to add this data to Wikidata in a structured way. Here is an example file: https://fragdenstaat.de/anfrage/energiebedarfsausweis-fur-gebaude-astrid-lindgren-grundschule-kurt-kreiselmaier-platz-1/531066/anhang/AushangEnergieausweis-Astrid-Lindgren-Schule_geschwaerzt.pdf --Silsha (talk) 13:53, 29 October 2020 (UTC)

Discussion

•  Support However your linked source doesn't have a ".0" on the heating energy number, so I don't think your regexes for allowed values make sense. Just allow any numeric value and let people add the numbers as they are presented. ArthurPSmith (talk) 19:19, 29 October 2020 (UTC)
  • Thanks for your comment. I searched through some more energy certificates and found out that the power consumption index can also contain a decimal point (https://fragdenstaat.de/anfrage/energiebedarfsausweis-fur-gebaude-volkshochschule-siegen-markt-2557072-siegen/533527/anhang/1.3130_KrnchenCenter_Aushang.pdf). I'm updating the regex to (\d*\.)?\d+, which should allow any numeric value (feel free to correct me if I'm wrong). --Silsha (talk) 19:37, 29 October 2020 (UTC)
• Unit of values, is that kilowatt hour per square metre per year (Q64740041)? --- Jura 13:13, 14 November 2020 (UTC)
  • Looks right. But Q64740041 talks about "power unit for solar irradiance". So I am not sure if we can refer to it. --Silsha (talk) 13:57, 14 November 2020 (UTC)
