An overview of the development of outdoor thermal comfort (OTC) indices based on type of approach, from linear equation approach – to adaptive thermal comfort model – is provided and the advantages and limitations of each index are presented. Subjective neutral ranges from 31 studies conducted in hot-humid regions were assessed on the basis of geographical location, Köppen-Geiger’s climate classification, parameters, a survey method, instrumentation set-up, respondent profile, method of analysis, neutral range, and coefficient of determinations in order to gain an understanding of their deviations. The review of 31 calibration studies of (m)PET’s, (OUT_)SET*’s and UTCI’s neutral ranges indicated that the lower threshold of (m)PET’s neutral range needs to be lowered, while the lower threshold of (OUT_)SET*’s and UTCI’s ranges should be raised. The appropriateness of (OUT_)SET*’s thermal range for hot climates was proven by its full-coverage neutral range in the evaluation. However, the accurate response to ambient thermal conditions was determined by the advancement of a human thermoregulatory model.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Hot-humid regions,Human thermal model,Neutral range,Outdoor thermal comfort (OTC) indices[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]Authors gratefully acknowledge the funding from USAID through SHERA program – Centre for Development of Sustainable Region (CDSR) .[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1016/j.uclim.2019.100531[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
