Moreover, the temperature in the contemporary era was found to be 1.5 degrees Celsius cooler than that of the critical status scenario. The results indicate that the evaluated comfort-providing area in the Safavid scenario is 7–17 times more favorable than the others. The predicted mean vote (PMV) model was used for measuring thermal comfort. The mixed strategy used in this study relies on logical reasoning and software-assisted evaluation for comparing the three scenarios. With a diachronic approach to the study of the historical Chahar Bagh Street in Isfahan, this paper investigates the impact of the structural changes on its micro-climate in three different scenarios, i.e., the street with its features during the Safavid Era (from 1501 to 1736) the street in its current status and finally a probable critical condition resulting from complete elimination of natural elements from the environment.

Both ASHRAE 55 and ISO 7730 (2005) use similar criteria for thermal comfort and are. An old technique used during the past centuries - in both hot and dry climates of the central cities of Iran - was the moderation of micro-climates via water and plants. He graduated from Loughborough University in ergonomics in 1974. According to a normative approach, it was essential for the authors to. As the urbanization expands, and the green spaces diminish, the heat islands begin to emerge. The comfort zone is mainly determined by provisions provided in standard ISO 7730.

report is the current implementation of ventilative cooling in EN standards, ISO standards. Cities directly influence micro-climates. TDS 04a Thermal Comfort 1 of 7 Foreword This Technical Data Sheet (TDS) should be used in conjunction with the British Standard BS EN ISO 7730 Ergonomics of the thermal environment (Analytical determination and interpretation of thermal comfort using calculation of the PMV and PPD indices and local thermal comfort criteria).
