WebConvection-cooling is sometimes loosely assumed to be described by Newton's law of cooling. Newton's law states that the rate of heat loss of a body is proportional to the difference in temperatures between the body and its surroundings while under the effects of a breeze. The constant of proportionality is the heat transfer coefficient. Webheating and cooling degree days use a baseline of 65°F— a typical baseline used by the Na tional Oceanic and Atmospheric Administration (NOAA) . Heating degree days are summations of negative differences between the mean daily temperature and the 65° F base; cooling degree days are summations of positive differences from the 65 °F base.
