Its effect on radiant heat, however, may augment these benefits. In this study, the hypothesis that radiant heat affects subjective comfort ratings in a vehicle was tested. IRR films were systematically applied to the driver-side window of an outdoor stationary vehicle. In Phase 1, cabin air temperature was controlled while participants rated their thermal comfort. In Phase 2, air temperature was adjusted according to participants' responses. Results in Phase 1 showed that the IRR treatment improved thermal comfort on the left forearm, which was exposed to direct solar irradiance, but not whole-body thermal comfort. In Phase 2, participants indicated that they were comfortable at a higher air temperature (mean of 2.5\u00b0F [1.4\u00b0C]) with the IRR treatment than in the untreated condition. The results indicate that reducing radiant heat via IRR treatment affects subjective assessments of thermal comfort and allows occupants to maintain the same level of comfort in a warmer vehicle cabin. Applications of this research include future implementations of IRR treatment on automotive glass that may lead to greater fuel economy savings and occupant comfort than have previously been estimated. <\/jats:p>","DOI":"10.1518\/001872005775570925","type":"journal-article","created":{"date-parts":[[2006,2,5]],"date-time":"2006-02-05T00:26:27Z","timestamp":1139099187000},"page":"827-839","source":"Crossref","is-referenced-by-count":16,"title":["Radiant Heat and Thermal Comfort in Vehicles"],"prefix":"10.1177","volume":"47","author":[{"given":"Joel M.","family":"Devonshire","sequence":"first","affiliation":[{"name":"University of Michigan Transportation Research Institute, Ann Arbor, Michigan"}]},{"given":"James R.","family":"Sayer","sequence":"additional","affiliation":[{"name":"University of Michigan Transportation Research Institute, Ann Arbor, Michigan"}]}],"member":"179","published-online":{"date-parts":[[2005,12,1]]},"reference":[{"key":"atypb1","volume-title":"The effects of infrared-reflective and antireflective glazing on thermal comfort and visual performance: A literature review","author":"Devonshire, J.","year":"2002"},{"key":"atypb2","volume-title":"The effects of infrared-reflective treatment on thermal comfort during transient conditions","author":"Devonshire, J.","year":"2003"},{"key":"atypb3","volume-title":"Thermal comfort: Analysis and applications in environmental engineering.","author":"Fanger, P.
