AbstractA guarded hot-box is used t o determine the U-value of a wall specimen a t two different mean temperatures. With the hot side temperature held constant, the cold side temperature is varied at a constant rate during the transition between the two steady-state conditions. The results of this test are used to determine three time constants of the wall, which are then used to calculate the coefficients of the z-transfer function for that wall.
