+## (Further) Development and Testing of the Energy Extension for CityJSON (v1.x)
+
+The goal of the thesis is to extend and further improve the current development of the CityJSON Energy Extension. The existing implementation is the result of a MSc Thesis finished in June 2022. The CityJSON extension is expected to support several energy applications as its counterpart the [CityGML Energy ADE](https://opengeospatialdata.springeropen.com/track/pdf/10.1186/s40965-018-0042-y.pdf) does.

+
+It is expected that this implementation will include the development of a software tool to translate the data from the CityJSON and CityGML encoding formats.
+
+Attendance of elective course [GEO5014](https://studiegids.tudelft.nl/a101_displayCourse.do?course_id=52747) in Q5 is highly recommended, as many relevant topics needed for this thesis will be covered.
