Investigation of Indoor Asymmetric Thermal Radiation in Tibet Plateau: Case Study of a Typical Office Building
Round 1
Reviewer 1 Report
Over all, this paper have a good structure and organized. Some weakness point which need more details are listed below:
Page 2: Abbreviations: ASHRE please re arrange in one line.
Line 43: please remove dot after References [11]
Line 100-104: More explanations are required to clarify the research gap of this study.
Line 129: I recommended to add schematic diagram for the selected office building (sample for one room) to display the important internal details such as heating radiator position, window …etc.
Table 2: please check the thickness of the external window and the partitions. Also check the Heat transfer coefficient (W/m2·K). Why this big difference between parts. Please double-check
Line 136: I recommended to add figures for the measurements devices.
Line 164: please add references for the equation 1.
Line 219: please specify which model (turbulence model) that you use in this investigation.
Figure 3: More detailed information are required. For figure 3 a and b I recommended to number the internal parts and internal heat sources and give the name in figure caption. For figure 3 c, more details are required on mesh distribution especially near the heat sources and walls.
Figure 5: please explain for the reader why this high fluctuation in indoor air temperature. The indoor air temperature should be relatively under control as using heating system of as the influence of internal heat sources. Please clarify this point.
Line 288: As the study mostly depend on simulation results, a high efforts and details are required for the validation work. Pleas clarify this important part.
Line 330: W/m2 rather than W/m2
Figure 10: need to specify the wall position i.e south, north…etc., window, and the internal heat sources.
Line 350: why you use 0.6 m please explain for the reader.
For more details, I recommended to use all high (floor to ceiling) to see the temperature profile for all room domain.
Line 413: “VATD should be less than 4 ℃ “. I think should be less than 3 ℃. Please double check.
Figure 14: double check on chest and back of contour temperature.
Line 566: the conclusion is too long. I recommended to re-write.

Reviewer 2 Report
I have evaluated this article which deals with Asymmetric thermal radiation in office buildings in Lhasa.
The authors present an interesting approach to the problem of how to achieve thermal comfort within modern buildings in this remote and traditional architecture area.
The article seems thoroughly researched, there is a proper and ordered taxonomy of the case under considerations.
The equations are correct and the model seems clear. But the part of radiation is not very well defined. The input of solar radiation coming through the windows does not appear upfront in this study.
Although the thermal study is satisfactory and very well detailed, we would appreciate more concretion as regarding the introduction of sunlight in the space.
Overall, the hypothesis and methodology are well established. The experiments are adequately set and conducted. There is little mention of the type of window and insulation employed.
The comparison with Beijing is perhaps justified but the plans of the equivalent office building in Beijing are not defined.
The key-points of the article are deftly solved.
The discussion is adequate and extensive. The architecture selected seems a bit rigid of the cuboid type, I wonder how the authors could extend their models to other types of architecture and make the results more universal.
The scope and possible future developments of this research, together with conclusions could perhaps be enhanced.
Suggestions:
Is it possible, to extend this kind of simulation to the summer months? What will happen in other climates? What are the artificial means available to compensate for the lacks detected?
Summary of assessment: Favourable. I recommend accepting this article after minor adjustments in the sense discussed previously.
