Virtual Light Sensing Technology for Fast Calculation of Daylight Autonomy Metricsâ€
Round 1
Reviewer 1 Report
The article raises a very important issue of daylighting analysis in newly designed architectural objects. It has a good introduction to the problem. It is short but concise and readable.
However, the authors should emphasise the purpose of their work more intensely. It is good, but it needs to sound more robust. Same with methodology.
What is the reason for using inch units? I have nothing against this unit, but this fact surprises me. I think the journal requires SI units; if other units appear, they should be converted.
When using organisation names, use their full name. I mean for CIE, IES.
Line 211: provide literature references for the Monte Carlo algorithm. This is a generally known and used lighting calculation algorithm, but you should also keep non-informed readers in mind.
Chapters 4.1, 4.2, and 4.3 were described very quickly. Some parts of the text could be more legible.
You need to present your achievements better. They are noteworthy.
The Figures in your work are also a problem. They have a very low resolution.
The editing of the text also has errors, but the journal will probably correct this if the article is accepted for publication.

Reviewer 2 Report
Dea Authors,
The work presented here is a method for fast calculation of daylight illumination metrics. The novel simulation approach enabled calculating them in reasonable time compared to FMCRT methods whereas the results did not differ from validated data more by than 1-2 %. Also an optimization procedure was developed to determine the blinds configuration of a modelled building at any time.
The structure of the paper is clear and easy to follow. Although, spell checking is required and a native speaker might read throught the manuscript to improve language.
A have only some minor questions and comments which are the followings:
1. In chapter 2. Automatic Specification of Sensing Area, I suggest using an example with metric units instead of inches for better understanding in a wide range of readers.
2. For chapter 4.1: Can the blinds only be partly closed in your model? Would is alter the results if several blinds were partly closed instead of one fully closed?
3. In Fig. 2, the axes should be titled for better understanding.
4. Some sections in the results chapter describe fully methodical parts. These sections should be moved to a separate chapter.
