Indices excluded from further analysis due to criterion (C). Full index names and references are shown in Table 1

C	Index	Reason
9	PhS	Evaluates reaction of body immediately after exposure to an environment (Blazejczyk 2005a; Blazejczyk 2005b). Thus, PhS evaluates time scales shorter than 10 min, which cannot be resolved with ORMs
9	STI	Same as PhS
10	OTEI	No assessment scale defined
10	ThBalb	No assessment scale defined. An assessment scale is defined for a regression version, but that does not include long-wave radiation (C5, Appendix A in ESM 1)
11	HEBIDEX	Assessment scale is derived from thermal sensation votes of beach tourists (de Freitas 1985)
11	STEBIDEX	Same as HEBIDEX
11	OUT_SET*	Contradicting assessment scales derived from thermal sensation votes for different locations by different authors (Tsitoura et al. (2014), Watanabe et al. (2014), and Spagnolo and de Dear (2003))
