September 8, 2013 Release, Version 2014.2.30.9990

ANSI/ASHRAE Standard 140

The results of the Standard 140-2011 tests from September 8, 2013 are posted below, which include the full set of version 3.4 results for comparative purposes. The testing shows that GBS remains stable and within the bounds of acceptable results for Standard 140.

The minor differences, where noted, are due to two things, but results still fall within the bounds of acceptable results as compared with other simulation tools.

1. The altitude of the DRYCOLD.bin weather file changed from 5279 feet to an altitude of 0. This has been noted as a bug to be addressed in an upcoming release.
2. A door construction bug was fixed (from and insulation value of R-5 to R-2).
