heal.abstract	The use of a stepwise steady-state method based on the solution of time-dependent energy and mass balance equations, thus referred as the transient method, is proposed instead of the traditional steady-state method for predicting degree-hours. The proposed method makes use of real climatic, structural, and animal data. It is more accurate in calculating the heating and cooling needs and the microenvironment inside a growing-finishing swine building and in evaluating the hourly likelihood of swine heat-stress. More specifically, the heating degree-hours estimated using the proposed method were only 1.3% of those calculated with the steady-state method, whereas the cooling degree-hours estimated using the steady-state method were only 26.0% of those calculated with the proposed method. Growing-finishing swine potentially experienced minor, medium, and extreme heat-stress during ""cold,"" ""mild,"" and ""hot"" weather, respectively.	en
