Numerical Validation of the Radiative Model for the Solar Cadaster Developed for Greater Geneva

Round 1

Reviewer 1 Report

The article is well written and provides sufficient information on the tools and methods. The discusion and conclusions are based on the calculations and clear.

However I have few minor remarks:

Maybe the title could be changed as it suggests that the solar Cadaster was calculated for the whole area of Greater Geneva, while it was calculated only for its meteorological data. The real topology and real buildings were not taken into account.

Please add short conclusions at the end of the abstract.

Line 113: Please explain the abbreviation GIS (if CAD is explained then GIS also should be)

General commets

1. The Hay model was used in the Solar Cadaster method. This is an important part of the article. Unfortunately, the model description is incomplete and with errors, not all variables are described, some variables are poorly described. The model description should be corrected and supplemented, and literature sources should be provided.
2. In computer simulations, there are used  numerical models which require the set of a grid of points. These points should be shown.
   The solutions depend on the grid of points used. As this is a model validation, the effect of the mesh on the results should be investigated.
3. Fig. 15 shows that one irradiance value was obtained on the roofs. This is also written in the text, therefore Fig. 15 seems unnecessary. On the other hand, it may be the effect of a grid of points that is too rare. This should be checked.
4. Fig. 16 - Bitmaps indicate that  the outlines of changes of irradiance values have shapes of rectangles. This is probably due to the grid of points used. Rather, the outlines should be rounded. This is also an argument for checking the influence of the mesh on the calculation results.
5. The authors note that the results differ because equations from which the irradiance is calculated are drawn up at other points. It should be checked what will happen, if the sets of points will be moves so that the equations will be placed on points with the same location.

Detailed comments

Fig.7-Fig.12 - Lines which connect points shoud be removed. Then authors either ought to leave the points only or enter lines that will interpolate these results.
Fig.8 - Fig.14 - In the legend the full names of the methods used should be given.
