Firms offering BIM Modeling services should clearly understand the process of simulating an energy analytical model in order to analyze the energy needs of a structure. This is essential to minimize the dependence of the building on artificial energy sources by making optimum use of the natural sources like the sun and the wind etc. The analysis also helps you study the behavioral patterns of the inhabitants to gauge the effect of their habits on the energy use and educate them about the best practices to be adopted to make the building more energy efficient.
