Increasing demand for energy due to population growth and global warming has led to numerous environmental issues such as deforestation, destruction of the ozone layer, drought, storms, and floods. These have encouraged researchers to seek new ways to use clean, renewable energies. The construction of Zero Energy buildings in Iran cities can be a significant step forward in economic development and pollution reduction in metropolitan areas. This study aims to identify and prioritize suitable cities in Iran to build Zero Energy buildings. For this purpose, the fuzzy Delphi and multi-attribute decision-making (MADM) methods have been used. The cities that are suitable for the construction of zero-energy buildings were selected through interviews with individuals who are experts in the fields of architecture, urban planning, and energy management and who are familiar with the construction of Zero Energy buildings, as well as considering the results of previous research and the characteristics of different cities. Then, with the fuzzy Delphi method, the necessary indicators for the priority of the selected cities were determined, and their weight was determined. After that, the cities were prioritized using MADM methods. The results showed that Yasuj, Shiraz, Tabriz, and Arak are suitable cities to build Zero Energy buildings in Iran.

The thermal comfort analysis models specify the acceptable thermal condition such as temperature, humidity, and air movement. Personal, measurable environmental, and psychological factors affect thermal comfort. Psychological factors are often overlooked because they are difficult to quantify. These factors based on different hypotheses such as the hue-heat hypothesis affect the human perception of thermal comfort. The hue-heat hypothesis indicates the relationship between warm and cool colours and subjective evaluation of thermal comfort. This paper used a questionnaire (Actual Sensation Vote) to examine the association between these factors and thermal sensation, humidity sensation, and draught sensation. Totally 65 volunteers from commercial buildings in district 2 of Tehran answered the questionnaires. Cronbach’s alpha is calculated and showed the consistent reliability of the questionnaires. Results indicated that in winter, thermal sensation votes increase in hot spaces (warm colour and low lighting colour temperature) compared to two other spaces. Likewise, in summer, thermal sensation votes decrease in cold spaces (cool colour and high lighting colour temperature) compared to two other spaces. In addition, results clarified that discomfort sensation in the head, neck, and chest is more than in other parts of our bodies. Therefore, regarding thermal comfort, hot spaces are better in winter, and cold spaces are better in summer.
