SL2201-PMV05: Processed Dataset

Equal-PMV indoor conditions may elicit distinct physiological responses: modulation by sex and time-of-day Abstract. Indoor environments can meet the same Predicted Mean Vote (PMV) while differing in air temperature, mean radiant temperature, air speed, and clothing; these component mixes may recruit different thermoeffectors that PMV does not resolve. In a repeated-measures pilot (N=11; 5 male, 6 female), we created four office-like scenarios tuned to PMV≈0.5 and ran morning and afternoon sessions on separate days. We recorded wrist skin temperature, tonic electrodermal activity (EDA), heart rate (HR), and HRV (RMSSD, LF/HF), plus thermal sensation (TSV), comfort (TCV), and alertness (KSS). Linear mixed-effects models (Scenario, Sex, Time-of-day; interactions; FDR for physiology, Holm for questionnaires) showed that equal-PMV scenarios produced distinct physiological profiles: scenario effects were largest for EDA, then HR and skin temperature, smaller for RMSSD and LF/HF. Sex differences were modality-specific (greater EDA reactivity in males; wider skin-temperature spreads in females), and time of day modestly elevated HR/EDA. Illustrative patterns included lower male skin-temperature rise with high EDA in the warm-with-fan/low-clothing scenario and opposite TSV biases under cool-air/warm-radiation. Findings highlight that “equal comfort” need not imply equal physiological load, motivating component-aware design and larger confirmatory studies. Datasets. Data uploaded here includes the timematched data with all subject, physiological responses and physical background measurements as a 1-minute resolution timeseries (00_SL2201_PMV05_CombinedData.csv).
