Huelsz , G. Barrios, J. Rojas Instituto de Energías Renovables, Universidad Nacional Autónoma de México, 62580 Temixco, Mor., Mexico highl i ghts graphical a bstrac t Method to generate a thermally equivalent wall to that composed by hollow-blocks. The thermal equivalence is valid for time-dependent conditions and for steady-state. The equivalent wall is composed by a set of homogeneous layers. This method can be implemented into whole-building simulations programs. article i nfo abstract Article history: An equivalent-homogeneous-layer-set (EHLS) method to account for the time-dependent heat transfer Received 11 January 2016 through a wall composed by hollow-blocks is proposed.
