Stress & Comfort

This study investigates how stress influences individuals' satisfaction with thermal comfort in office environments. Utilizing a combination of physical measurements (like air temperature and humidity) and psychological assessments (including various questionnaires), we explore the relationship between perceived environmental demands and individuals' coping resources. Our findings indicate that dissatisfaction with the thermal environment can be attributed to a combination of thermal factors, social deficiencies, and individual characteristics. This research contributes valuable insights to the field of building physics and environmental engineering.

  2. Comfort & Stress Introduction Methodology Results Conclusions Thermal comfort definition: ‘a condition of mind which expresses satisfaction with the thermal environment’, not a physical measurement Stress definition:an imbalance between the perceived demands of the environment and the perceived resources to cope with those demands • Source: • Thermal comfort. Analysis and applications in environmental engineering. P.O.Fanger, 1970 • European Agency of Safety and Health at Work, 2005 http://agency.osha.eu.int/tmp/publications/conference/magazine/5/index_3.htm 2/10

  3. Stress to Comfort? Research question Introduction Methodology Results Conclusions How does stress influence satisfaction with thermal comfort? Current thermal comfort model includes: (iii) air temperature, (iv) mean radiant temperature, (ii) activity level,(i) clothing insulation,(v) relative humidity, (vi) air velocity 3/10

  5. Stress & Comfort measured Introduction Methodology Results Conclusions • Research Objects:3 office in Eindhoven (n=46) • Measurements: • Physical: Air temperature [oC]; Mean radiant temperature [oC]; Relative humidity [%]; Air velocity [m/s]; CO2 concentration [ppm]; Airborne particles (≥0.3 μm and ≥1.0 μm) [counts/min] • Questionnaires: the office environment survey (HOPE) [Building Research Establishment Ltd, 2002]; extended cognitive failure questionnaire [Broadbent, et al 1982]; effort reward imbalance questionnaire[Siegris, Peter 1996]; chronic stressors [Cairney, et al 2003]; recent life events [Cairney, et al 2003] • Data analyses: Statistics, Multi variant analyses 5/10
