Abstract

Numerical models describing the concept of the adobe wall design for thermal comfort conditioning of buildings have been studied.  In the first of a two-string analyses, it is shown that the variations of the instantaneous attenuated temperature of the wall system as a function of phase lag is not well pronounced with a decrement rate of the order of 0.1% in relation to the solar-air temperature values.  In the second analysis, the variation of the internal surface temperature signature obeying an equation of the form:

 

appears to connote a better evaluating model for estimating thermal performance of the wall system, if the empirical constant is fixed at 2.2.
