#1373 Solar thermal collector listing update

[Danny Tam]

We received a new solar thermal collector listing from SRCC. Last time it was updated was 2-3 years ago, so we are due to make an update. Listing attached.

Danny - A couple of clarifying questions:

1. The attached spreadsheet has 230 rows. Only 33 of these rows represent NEW collectors not yet in the CBECC spreadsheet list. Why are the other rows included in the attached spreadsheet? Some of the Manufacturer or Brand names have changed from the CBECC list, but most are already identical with the corresponding OG-100 Number.
2. The attached spreadsheet list has different units than those currently used in CBECC: Area is in Ft2 rather than M2 (a simple enough conversion), Intercept is the same, but Slope does not indicate units and differs from CBECC's (W/m2°C) and values are positive rather than negative. Can you clarify the difference in Slope values?

Attaching a marked up spreadsheet indicating:

• 33 new records not in current CBECC spreadsheet
• Differences in existing CBECC spreadsheet records
• Unmarked rows already exist in CBECC
• There are over 700 collectors already in CBECC, so is there a difference between the existing models in the attached spreadsheet and the matching models already in CBECC?

SRCC OG-100 solar collectors list update (SVN Rev 2498):

• Based on attached SRCC OG-100 Export_20241112-CEC-RJH.xlsx
• Updated lookup spreadsheet, CSV, and 2022 and 2025 BEMEnums files
• Modified 2022 and 2025 Screens to display message to "Refer to latest SRCC OG-100 list to assure certification of selected collector"
• Modified CF1RPRF01E_Master.rule output rule to avoid runtime error when DHWSolarSys Azimuth or Tilt have not been user input.

@robhitchcock - verified all systems except one in SVN 2506.

@ttcec Thanks for catching this. This solar collector model is in CBECC-Res. So it can be selected by a user and properly simulated and reported. As it happens, these schema enumerations are not actually used in the CF1RPRF or downstream schemas, so I believe Diane is removing all collector Manufacturer, Brand, and Model enumeration lists from CF1RPRF schemas. However, these enumerations are in fact used in CBECC (MF, Com), so it needs to be added to the LMCC/NRCC base schemas.
