1. The case study mentioned does not conclude any details regarding the extent that the simulation tools can contribute in illumination distribution of urban space in early design stages. 

2. Writing is very poor and hardly understood in many parts. As the right terminology for lighting design field are not properly used. For example:
"Daily lighting": should be “Day light”
"Optical": should be "Visual" and so on

3. The research is just a shallow introduction to the simulation tools that shows examples of the work flow and changing materials and settings (e.g. using “ies” files and so); that what any simulation tool is intended to do for more than 10 years. Moreover, lighting schemes “decisions” based on those realistic visualizations are not discussed according to specific criteria and the validity of the simulation tools are not tested.  Thus the paper doesn't add any merits to the field.
