“In gearing up to teach a course called Building Science this semester, I somehow stumbled across your program Energy2D and Energ圓D. I do not know how many messages of this type you are receiving.” That is just awesome and I want to say thank you for all users. It is also very nice to see that three platforms are supportedĪnd every single one is free to use. “Thank you for your absolutely great app which helps me a lot for visualizing my lecture in thermodynamics. Hensen, Ulrich Knaack, & Gregor Zimmermann, Journal of Facade Design and Engineering the simulation results never divert from the exact solution more than 0.45☌ and it is thereforeĬonsidered acceptable to further use this model.” Of a concrete construction with the following properties were compared for this research. Those analytical solutions and the simulation results of the dynamic response to a 20☌ temperature step change on the surface Inspired by the approach described in Hensen and Nakhi (1994). To gain more confidence in the predictions with Energy2D, an analytical validation study was therefore carried out first, Energy2D is a relatively new program (Xie, 2012)Īnd is not yet widely used as a building performance simulation tool. “The software program Energy2D is used to solve the dynamic Fourier heat transfer equations for the Convective Concrete case. from Stefano Oss, European Journal of Physics Including those, for example, in which convective transport phenomena play a non-negligible role.” We have shown a solid reliability of the simulation in the description of our experiment: it can open the way to a basically unlimited number of applications, “.we have suggested the adoption of the platform Energy2D for a very effective “what-if” game in terms of the construction of cases of study eventually much more complex

The following is a list of books that have recommended Energy2D:

More than 40 scientific papers have used Energy2D as a research tool (not just a citation),ĭemonstrating its wide applications across science and engineering. The thermal patterns predicted by Energy2D roughly match those from a thermal camera. The pictures to the right show a comparison of the results of Energy2D simulations with images from infrared

That involve convection and radiation, Energy2D results should be considered as qualitative. The conduction part of Energy2D is highly accurate, but the convection and radiation parts are not 100% accurate.
