The envelope thermal behaviour in dynamic conditions is becoming essential to assess the whole year energy performance of buildings. International Standards describe in detail the theoretical approach, but few examples of experimental analyses and procedures exist to determine the performance of materials and components in unsteady - state conditions. The work is aimed at filling this vacancy, describing a modification of hot box devices, which are generally designed for stationary measurements, but they could be successfully used also for time -dependent investigations. Two different methods are proposed： a hot box system where one - day period sinusoidal solicitations in terms of temperature and heat flow are imposed, and another type of boundary condition, with a faster impulsive thermal driving force.
