Validation and simulations of a quasi-steady state heat balance model of residential walls
This paper discusses the validation of the model presented in a companion paper [1]. A test house was built, instrumented, and monitored. The results suggested that the model predicted reasonable well with a 9.6% difference when cumulative heat flows were compared. Because of the steady state principles used to construct the model, the measured data and model prediction showed a lag of approximately one hour. In all cases, the model underpredicted the peak heat fluxes by an average of 17%. Simulations were run to estimate total heat transfer in walls as a function of wall orientation and insulation level.
