| Abstract | The objective of this paper is to promote the “analysis of variance” in a computer simulation experiment regarding the determination of influential parameters on the thermal performance of single-family houses. A design of experiment was elaborated for the thermophysical parameters of a single-family house in the climate of Campo Grande-MS, and computer simulation of the thermal performance using EnergyPlus was performed. Nine parameters related to the envelope of the house were varied on two levels, reaching 512 simulation runs. The analysis of variance was used to explain the influence of each parameter on the thermal performance of the house, which was represented by degree-hours of heating and cooling. One can find that the most important parameters for cooling performance were the solar absorptance and thermal transmittance of the roof, and for the heating performance were the thermal transmittance of the external walls and the roof emissivity. The degree-hour for cooling, in the case of this climate, is more representative than the degree-hour for heating; which ranged from 84-21136°Ch. One can conclude that the method of analysis of variance is feasible for the purposes of computer simulation, and has the ability to show, with great statistical accuracy, the most influential parameters in the analysed output. However, the method is limited by the number of simulation, which grows exponentially as the number of parameters and variation levels considered in the experiment increase, demanding greater computational effort and processing time. |
