dc.description.abstract We tested the hypothesis that reducing radiant heat by the application of an infraredreflective (IRR) treatment will allow occupants to maintain the same level of comfort in a warmer vehicle cabin. Participants were passengers in a mid-sized sedan that was driven for 46 minutes along a 41.5-mile route. Each participant experienced two drives: one with infrared-reflective (IRR) film applied to all glazing surfaces of the vehicle, and one with no IRR treatment applied. Every two minutes, participants were asked to rate their thermal sensation at five body locations and to indicate whether, overall, they felt too hot or too cold. Cabin air temperature in the vehicle was raised or lowered depending on participants’ responses. Although the IRR treatment did not have a statistically significant effect on the air temperature that participants found comfortable, the trend was in the expected direction, and a decrease in the average time required to reach thermal comfort was observed. IRR-treated drives were also associated with reductions in air conditioner compressor use and fuel consumption. While the physical effects in this study confirmed findings of previous studies, data concerning the relationship between radiant heat and comfortable air temperature were more complicated and inconclusive and would benefit from further research. en_US
