Abstract
The effect of the internal thermal structure of building walls and roofs on their frequency responses, of period of 24 h, is examined. The notion of the thermal structure factors of a wall is introduced. Correlation between the fre quency dependent and structure dependent thermal characteristics is analyzed for the representative sets of building walls and roofs from ASHRAE Handbook 1989: Fundamentals. Most evident is the correlation between the decrement factor and the structure dependent time constant, between the admittance response amplitude and the appropriate thermal mass factor, and between the time lag and its estimated value, and also thickness of a wall.Keywords
