Effect on Thermal Comfort of Radiant Heat Exchange Near Single Glazed Windows
It has become common practice over the last two decades to clad commercial buildings with curtain wall systems with large windows. Typically viewing panes are continuous around the building perimeter and extend from sills at about 900 mm above the floor to the ceiling line. Anecdotal evidence has suggested that people in the vicinity of these windows can suffer from hot and cold discomfort depending on season and time of day. This paper will report the results of a longitudinal investigation of these phenomena spanning two years in a typical office building in an inner suburban business district. It was found that radiant asymmetry and associated diurnal temperature shifts had a significant impact on thermal comfort in proximity to the windows. A difference of one comfort vote interval could be attributed to a frontal radiant temperature difference of about 2.8 oC. A 33 oC difference brought about a one vote difference for persons side on to the radiant source/sink. Also change in operative temperature in perimeter zones as the sun moved around the building had the effect of moving the comfort vote approximately one interval for every two degrees of shift over approximately three hours.
