Abstract :

Background and Objective: As the level of people's expectations and their need to create comfort conditions in different environments becomes more and more noticeable, so the climate and environmental conditions, the inevitable psychological and physical impact on human comfort conditions have. Therefore, determining the range of thermal comfort for each climatic zone in different forms of construction seems necessary. The purpose of this study is to identify the range of thermal comfort of the interior of multi-story residential buildings using predictive indicators of average views and average real views.In this regard, the forthcoming research will answer the question: What is the neutral temperature in multi-story residential buildings in Shiraz in the hot season?Method: In this research, different research methods have been used according to its various aspects, but the implementation stages of the research were divided into two parts: "data collection and information" and "analysis". Data and information required for this present study, based on experimental and field methods, the two main methods of questionnaire and measurement of variables using environmental measuring devices (Lutron LM-8000A and Extech T30) , Samples were collected from residential units and then the necessary rulings were issued with their analytical, inferential and classification descriptions.Findings: Most people in all studied spaces were feeling warm at ASHRAE scale. The air temperature of the interior spaces and predicted mean vote (PMV) of the comments as well as the actual mean vote (AMV) of the correlation coefficient are incremental and positive.Discussion and Conclusion: The results show that outside temperature and neutral temperature have a special relationship in warm months and these results are minor differences with other global studies.
