Description
Enhancement Request
The 2020 edition of NIST Handbook 135, Life Cycle Costing Manual for the Federal Energy Management Program extends the maximum study period from 25 years to 40 years.
https://nvlpubs.nist.gov/nistpubs/hb/2020/NIST.HB.135-2020.pdf
The limit is hardcoded into OpenStudio here:
https://github.com/NREL/OpenStudio/blob/b8d0e3a845faa3c34fd6263e53e931309101d296/src/model/LifeCycleCostParameters.cpp#L528
It would be nice if this limit was documented in the OpenStudio IDD, SDK documentation, an error message, etc., since currently the maximum study period is nominally limited by the IDD to 100 years, but is really silently limited based on analysis choice.
