Factors affecting ‘end-of-day’ window position in a non-air-conditioned office building

• Season appears to have influence on the end-of-day window position.
• Being located on the ground floor may influence the end-of-day window position.
• Males and females appear to have different behaviour on end-of-day window positions.
• Personal preference plays a role in determining end-of-day window position.
• The distribution of types of window users is dependent on gender and floor level.

This paper presents a longitudinal study observing people's use of windows in mixed mode cellular offices, and sets out to identify factors other than air temperature, that have a significant influence on window operation. The work focuses on the final position of the window at the end of the working day. The results have been compared to other published work and the building is found to have similar characteristics when it and its occupants are treated as a whole. When sub-sets of the data are examined, the factors of season, floor level, gender, and personal preference emerge as having a statistically significant effect on the end-of-day window position in the building examined and these findings are properly discussed with relevant references.
