Effect of a) thermal comfort on cognitive function scores, b) yesterday’s sleep on cognitive function scores, c) building classification on Sleep Scores, and d) light levels on Sleep Scores, using generalized linear mixed effect models with 95% confidence intervals, treating building and participant as random effects. The effect size for thermal comfort is comparing cognitive scores from tests taken by participants within the ASHRAE Standard 55-2013 comfort zone to those without. The effect sizes for yesterday’s sleep and light correspond to a 25% change in Sleep Score and 300 lux change in illuminance respectively.
