| There are many energy modeling software packages available today, but the abilities of one program does not satisfy all energy modeling needs. The purpose of this study is to create a combined simulation using eQuest and TRNSYS. EQuest has the power of DOE-2 running its simulation engine, and consequently is the industry standard for building energy simulation. TRNSYS has a vast library of components, many of which are not capable of being modeled in other software packages. It also is developed and supported by an international group of engineering firms, so the span of the types of systems the user can create is truly global.;Five simulations were created for comparison, two of which are eQuest-TRNSYS combined simulations. The results of each simulation are compared to each other and the base simulation, which was validated using actual utility data. Then the two methods for combination, as developed by the author, are described. Both methods use outputs from an eQuest model as inputs for equipment in the TRNSYS simulation. One simulation uses the Direct Load Imposition Method and the other uses the Return Air Properties Method. The results of this study have truly shown how useful a combined eQuest-TRNSYS simulation can be. |
