90.1 PRM: explicitly set dayofWeekforStartDay

[eringold]

I'm trying to use model_create_prm_stable_baseline_building in openstudio-standards v0.4.0 (packaged with OS 3.6.0) to generate the baseline for a propsed Outpatient building, and encountering a number of issues with either the model setup, or cases where the standards methods don't handle missing information gracefully. I'll try to document them as issues as I find them.

Models that use TMY files typically don't have 'dayofWeekforStartDay' set in YearDescription, and calling `model.getYearDescription.dayofWeekForStartDay' will return 'UseWeatherFile'. This causes an error here:

openstudio-standards/lib/openstudio-standards/standards/Standards.ScheduleRuleset.rb

Line 674 in d332605

if day_of_week >= 1 && day_of_week <= 5

because day_of_week and start_day_num are nil (not found in start_day_map).

Suggest ensuring that models with TMY files attached have a valid start day, either by inserting model.getYearDescription.setDayofWeekforStartDay("Sunday") somewhere, or having a default set within get_weekday_values_from_8760.
