What is the confidence interval in ashashrae 140?
- ASHRAE standard 140 suggests a confidence interval, which describes a reasonable threshold of economic uncertainty. It means the energy analysis of software disagreements within this range would result in relatively insignificant utility cost disagreements based on principal fuel charges.
How well do PHPP results match ASHRAE 140?
- For a total of 38 test cases described by ASHRAE 140, PHPP results were within the confidence interval of the reference software for all but one case, which modelled the impact of a south window overhang on cooling energy demand. PHPP V9.6 Validation using ANSI/ASHRAE Standard 140-2017 vi
