University of Twente

University of Twente Energy API

The university's own API, and the only contract in this profile it wrote. A public, unauthenticated REST service on the university's own network (energyapi.utwente.nl, 130.89.3.170, ASP.NET Core / Kestrel) returning historical metered energy for 103 campus resources — individual buildings such as bastille and boortoren plus the campus-wide universiteit-twente roll-up — across electricity, gas, heat, water and solar, at hour, day, week, month or year resolution, back to at least 2019. Setting co2=true returns the series in kg CO2e against the Dutch national energy-mix emission factor. An OpenAPI 3.0.1 document and a Swagger UI are published at the host. Two contract defects were measured and are recorded in errors/: the spec declares RFC 7807 ProblemDetails on 400 but the service returns a bespoke {error, results} envelope, and GET /api/Dashboard is documented as 200 but returned 400 when probed. info.contact names Realised, the contracted developer, rather than the university.

      description: 'Resource and energy type can only contain lower case a-z, contain 0-9 and contain ''-'' instead of spaces.


        Timezone should be specified in a ISO8601 format, e.g.: yyyy-MM-ddTHH:mm:ssZ, providing an UTC time.

        If a non UTC timestamp is provided, e.g.: yyyy-MM-dd HH:mm, the timestamp is considered to be in ''Europe/Amsterdam''.

        The returned results are always UTC.


        The resolution must be one of the following: hour, day, week, month, year and will group the results accordingly following the ranges in "Europe/Amsterdam" timezone.


        Electricity or solar data can be requested in their CO2 equivalent. To get this information, set the parameter `co2` to `true`.
