Abstract
ABSTRACTIn Canada and much of the world, high-rise residential buildings with large glazing areas are increasing in popularity. These buildings are associated with lower thermal resistance envelopes and higher solar gains than more traditional construction with smaller windows. This study explores the comfort implications and usability in condominiums by performing a field study of 20 units: 10 with large window areas (LW) and 10 with medium-sized window areas. Occupant comfort was assessed in summer and winter, through two open-ended surveys, infrared thermography, and recorded interior temperature and humidity. LW occupants more often report uneven interior temperature distributions and windows as a source of discomfort in winter. One quarter of condo units experience condensation on windows, indicating window and frame improvements may benefit both groups. This exploratory study identifies key issues and occupant preferences within condominiums to guide future research on this building type.
