In this paper, an analytical model for buildings simulation and performance evaluation has been introduced and compared to existing numerical models already used in simulation tools. The proposed analytical model is based on the quadrupole approach, which is used for solving partial differential linear equations, while the numerical model is mainly provided by EnergyPlus simulation tool. To validate the proposed analytical model, results have been confronted to those of the BESTEST standard case 600 FF (Light weighted free-floating building) and 900 FF (Heavy weighted free-floating building). These latter are based on the ANSI/ASHRAE norm standard 140-2014 “Standard Method of Test for the Evaluation of Building Energy Analysis Computer Programs”. Simulations have been conducted by solving, in transient conditions, the heat equation and assessing then the temperature evolution inside the building’s zone. Results are reported and proved the accuracy of the proposed analytical model in terms of transient regime resolution since it considers all the necessary data and dynamics, to model the building and its internal gains without simplifications or hypothesis. Besides, it requires very low simulation time, which is required for large scale buildings’ simulations. |
