Surface temperatures are measured using infrared thermography and an external referencing technique. This technique allows detailed mapping of surface temperatures that is non-intrusive. The glazings were placed between warm and cold environmental chambers that were operated at conditions corresponding to standard design conditions for winter heating. The temperatures conditions are 21.1 °C (70 °F) and -17.8 °C (0 °F) on the warm and cold sides, respectively. Film coefficients varied somewhat with average conditions of about 7.6 W/m<sup>2</sup> K (1.34 Btu/h ft<sup>2</sup> °F) for the warm-side and 28.9 W/m<sup>2</sup> K (5.1 Btu/h ft<sup>2</sup> °F) for the cold-side. Surface temperature data are plotted for the vertical distribution along the centerline of the IG and for the horizontal distribution along the centerline. This paper is part of larger collaborative effort that studied the same set of glazings.</p>1 aGriffith, Brent, T.1 aTurler, Daniel1 aArasteh, Dariush, K.  uhttps://facades.lbl.gov/publications/surface-temperatures-insulated
