The article is devoted to the description of a natural experiment to assess the comfort of the internal microclimate in the premises of a residential building using the method of subjective expert assessment in the conditions of the hot and sunny climate of Syria.
The current popularity of the subjective assessment method is noted, since it is a real test of the conclusions that are given in the process of objective experimental studies.
The article describes the preparatory stage of the experiment, the process of selecting observations, forming a questionnaire, the results obtained and the conclusions made. The assessment scale used by observers is also noted. The history of the development and improvement of the method of subjective expert assessment is analysed and variant methods of its application are described. Based on the results of the experiment, a number of conclusions are made, which are used by the authors along with the conclusions obtained during the objective stage of the experiment on a real object.
The main conclusion is made about the relevance of the subjective expert method of research, as a result of which various aspects are revealed that were not taken into account in the course of the objective experiment conducted earlier. The subjective stage covered a larger range of issues related to the comfort of the internal microclimate. In particular, in addition to the quality of the light environment, the issues of insolation and sun protection and the psychological connection of observers with the external environment through window openings were also considered. Further, in the following studies it is planned to identify, by means of a comparative analysis, the correspondence of the conclusions obtained as a result of two full-scale experiments (objective and subjective) to each other and to make new, final conclusions. So far, it can only be stated that the subjective expert assessment reveals many new nuances that are not taken into account in the full-scale objective experiment, which should be specified in new studies continuing the ones considered.
