Abstract. In this article is presented validation of ANSYS Fluent with IEA BESTEST Task 34. Article stars with outlook to the topic, afterward are described steady-state cases used for validation. Thereafter is mentioned implementation of these cases on CFD. Article is concluded with presentation of the simulated results with a comparison of those from already validated simulation software by IEA. These validation shows high correlation with an older version of tested ANSYS as well as with other main software. The paper ends by discussion with an outline of future research.

Topic of the study is the investigation of potentialities of energy simulation for optimizing the building refurbishment, by taking into account impacts of both envelope renovation and HVAC system selection. Energy audit and refurbishment of the Day-Hospital building of a great Italian health care facility are proposed. A meticulous energy diagnosis of the base case building and design of a complete renovation-by improving both building envelope and HVAC systems-are presented. All data and boundary conditions for dynamic energy investigations have been carefully selected, also by means of in-situ studies, in order to provide a reliable model. In particular, several energy efficiency measures, with reference to building envelope and HVAC systems, are analyzed and it will be evidenced that, step-by-step, a proper design, supported by the adoption of numerical studies, may optimize the energy performances of the building, as well as the indoor microclimatic control.

“…The assumption of one-dimensionality is particularly grievous when it comes to ground-coupled surfaces. Follow-on exercises to supplement the BESTEST efforts 9 have shown that building energy simulation tools still do a poor job at predicting ground heat transfer unless they are coupled to computationally expensive fully 3D numerical models.…”
