What is it about?
The work questions the significance of the steady-state R-value for high mass wall systems through experimental analysis of the thermal behavior of two stabilized rammed earth building components representing a building envelope subjected to variable temperatures in the form of 24 hour cyclic sinusoidal inputs. It shows that when the environment temperature is used to quantify the thermal fluctuation of a zone the response of the walls surfaces to energy cycles can be determined by dynamic thermal transfer properties expressed in accordance with EN ISO 13786: 2007 relating cyclic heat flux to cyclic temperature variations.
