Reviewer 3 Report

Comments and Suggestions for Authors

The article aims to propose a OpenModelica simulation library for geothermal heat supply network system in residential buildings with detailed insights into in-house geothermal heat collectors (i.e. GHC). Moreover, two case studies have been conducted to evaluate the library effectiveness. The overall article is well-described with clear structure.

Besides descriptions about two simulation-based case studies, it is recommended to analyze simulation speed to show its computational performances as well as conduct benchmark between a real building performance and simulation results to guarantee model accuracy.
