This paper summarizes a study undertaken to reveal potential challenges and opportunities for using building performance simulation (BPS) tools. The paper reviews current trends in building simulation and outlines major criteria for BPS tools selection and evaluation based on analyzing user's needs for tools capabilities and requirement specifications. The research is carried out by means of a literature review and two online surveys. The findings are based on an inter-group comparison between architects and engineers'. The aim is to rank BPS tools selection criteria and compare ten state-of-thearts BPS tools in the USA market. Five criteria are composed to stack up against theories and practices of BPS. Based on the experience gained during the survey, suggested criteria are critically reviewed and tested. The final results indicate a wide gap between architects and engineers priorities and tools ranking. This gap is discussed and suggestions for improvement of current tools are presented.

“…The effects of thermal mass were not tested in these new cases because the original IEA BESTEST (Judkoff and Neymark 1995a) comparative cases explored building envelope thermal mass effects in detail in a single-zone context (and in a two-zone case with a sunspace). By excluding thermal inertia and minimizing other simultaneous effects, the current specialized multi-zone cases maximize diagnostic power, and also minimize the number of cases required to address the tested phenomena.…”

“…disagreement is 38%-73% for the absolute results (cases considered alone), and 46%-63% for the delta results (sensitivity results to isolate shading model effects, e.g., Case 630-620) (ANSI/ASHRAE 2007; Judkoff and Neymark 1995a). A graphic example of original single-zone shading case disagreement in the delta context, excerpted from IEA BESTEST, is ranges for the original single-zone IEA BESTEST shading cases for more realistic constructions, versus the final range of disagreement for the new in-depth diagnostic multi-zone shading cases.…”

“…Disagreement ranges for final delta results of the current multi-zone cases are smaller relative to mean sensitivities (see Figure 9), ranging from 5%-6% for shading by the front side of the fin (zones B, E, A, D) to 20%-21% for the back side of the fin (zones C, F). In-depth diagnostic multi-zone delta sensible cooling loads CONCLUSIONS A number of important test method and software improvements were made as a result of this work:  The improved final agreement for shading cases using idealized/modeled calorimetry enabled us to identify disagreements and diagnose errors that may have been missed using the original IEA BESTEST shading cases (Judkoff and Neymark 1995a). The level of disagreement in the original IEA BESTEST cases related to a number of simultaneous effects such as modeling realistic optical properties of glazing and interior opaque surfaces, along with realistic wall conduction and thermal mass.…”

“…The multi-zone non-airflow test cases represent an extension to IEA BESTEST (Judkoff and Neymark 1995a). This new work was conducted by the National Renewable Energy Laboratory (NREL), United States, in collaboration with a working group of international experts under International Energy Agency (IEA) Solar Heating and Cooling (SHC) Programme Task 34 and IEA Energy Conservation in Buildings and Community Systems (ECBCS) Programme Annex 43 (IEA 34/43).…”

A set of in-depth diagnostic test cases for multi-zone heat transfer was developed. These are designed to test the ability of building energy analysis tools to model multi-zone conduction, multi-zone shading, including automated building self-shading and modeling of internal windows between zones. A methodological advancement for this work, which enhances the diagnostic capability of the tests, is that the multi-zone shading and internal window test cases were specified using building zones designed to be modeled as precise calorimeters. The basic principle is that all solar radiation incident on an exterior window is captured within a zone, such that the zone cooling load is equivalent to the solar radiation incident on that window.
