The following series of figures shows the average responseswith the standard error of the mean (SEM) to the different comfortquestions (Fig. 3–7), with the accompanying text only highlightingsignificant effects. Statistical details for all analyses are shown inTable 3.Fig. 3 shows the answers to the first question in the cooling cycle(a) and the warming cycle (b).For the cooling cycle, participants felt significantly warmerunder the light of 2700 K than 6500 K (estimated marginal means[EMS]: M2700 K= 3.04 [SE = 0.17]; M6500 K= 2.639 [SE = 0.17]). Lowerambient temperatures (D Temp, M Temp) were associated withlower ratings, more towards ‘cold’, on the scale. A higher BMI wasassociated with higher ratings on the scale (b = .12).For the warming cycle, the main effect of lighting was not signif-icant. The main effect of D Temp was significant. In addition, therewas a significant interaction between lighting and time of testing:when testing was done in the morning, comfort was significantlyhigher under the light of 2700 K (M2700 K= 3.75, SE = .26) than underlight of 6500 K (M = 2.77, SE = .28). When testing was done in theafternoon, comfort did not differ under the two light settings.Fig. 4 shows the average responses to the second question.For the cooling cycle, the effect of lighting was significant withparticipants judging the environment as more thermally comfort-able under the light of 2700 K than 6500 K (EMS: M2700 K= 1.47[SE = .09]; M6500 K= 1.71 [SE = .09]). The effect of D Temp was alsosignificant. The effect of M Temp, the average temperature per ses-sion, was also significant.For the warming cycle, the effect of lighting was also significant,with participants judging the condition as more comfortable under2700 K than 6500 K (EMS: M2700 K= 1.15 [SE = .11]; M6500 K= 1.51[SE = .10]). The effect of D Temp was highly significant, i.e. temper-atures increase over the session, the score moves towards findingthe environment more comfortable. The effect of M Temp was alsosignificant, i.e. participants exposed to an environment with highermean session temperatures felt more comfortable. The main effectof testing time was also significant: In the afternoon testing session,the environment was judged as more comfortable (EMS: Mam= 1.52[SE = .10]; Mpm= 1.14 [SE = 0.10]).The interaction of light and D Temp was significant. We ranpairwise comparisons with D Temp 1.5◦C below
