Cannabis Lighting Standard Practice Studies - CPUC Response

CPUC Staff Response to the Cannabis Lighting Practice Studies Performed by Willdan and TRC

Modified Lighting Calculator (MLC) Version 13.1.2 Standard Practice - CPUC Staff Review Utilize the version labeled 'MLC_V13.1.2 (LOCKED) Rev 8.2.23 - FINAL' for all custom lighting projects at the earliest convenience, ensuring implementation within 60 days from August 15, 2023. Notably, this revision marks the incorporation of Multifamily buildings into the tool's scope. The non-residential segment of the tool retains its previous configuration, as seen in version 'MLC_V13.1.2 (LOCKED) Rev 5.5.23 – FINAL'. Note: An error was fixed on September 8, 2023 but the tool functionality remained the same as the version uploaded in August. 2023 Sep 8 2023 Sep 8 See history

Modified Lighting Calculator (MLC)

"MLC_V13.1.2 (LOCKED) Rev 5.5.23 - FINAL” to be used for all non-residential custom lighting projects starting from April 4, 2023. Any project with a signed project agreement or project application that occurs within 60 days of this date (i.e., April 4, 2023) can utilize the prior version of the tool.

Note: An error was fixed on May 5, 2023 but the tool functionality remained the same as the version uploaded in March.

DEER2020 Chiller Workbook

To support development of alternative measure definitions for chillers, and to extend the DEER chiller savings calculation methods to custom projects, DEER now includes a chiller savings calculation workbook, DEER2020_Chiller_Workbook-v1.xlsx, which utilizes the DEER chiller simulation results to develop savings of chiller measures that incorporate designated non-DEER measure characteristics.

Fuel Substitution Information
  • The CPUC provides a discussion regarding building decarbonization at CPUC's Building Decarbonization webpage.
  • The CPUC's Fuel Substitution Technical Guidance Document v.1 is both attached here and available at CPUC's Fuel Substitution in Energy Efficiency webpage.  Although the Draft Fuel Substitution Technical Guidance Document v2 has been posted to the same webpage, it has not yet been adopted by the CPUC.
  • The associated fuel-substitution calculator to be submitted with all fuel-substitution measure packages (both new or updated) using the Fuel Substitution Calculator v1.1 that is available exclusively at CPUC's Fuel Substitution in Energy Efficiency webpage. Again, although the Draft Fuel Substitution Calculator v2.0 has been posted to the same webpage, it has not yet been adopted by the CPUC. Measure package developers shall submit all fuel substitution measure packages using the Fuel Substitution Calculator v1.1 until otherwise notified.

RACC-FSC_v3

Modifications were made to enable distinguishing between updated EUL values and those previously in use.

No.

Modification

1

Eliminated the word "Viable" from two fieldnames in DEER's TechType table.

2

In TechType table, updated fieldname "HasElecAlt" to "HasElectricAlt" to align with DEER database.

3

Corrected formulas that were not working as intended on Intro worksheet in DEER Status Table.

4

Provided conditional formatting on 1 Device Builder worksheet to make it evident when formulas are replaced with values.

5

Synchronized workbook with DEER tables in DEER database.

6

Added "StartDate" and "ExpiryDate" fields on 1 Device Builder worksheet to manage updated EUL values at Device_Builds table and EUL_Basis pivot table (aligns with EUL_basis table in DEER).

7

Replicated rows involving technology types with revised EUL values on 1 Device Builder worksheet to enable selecting "TechType (NormUnit)" appropriate to measure installation year.

The RACC-FSC_v3 shall be used to calculate refrigerant leakage emissions and avoided costs of net refrigerant leakage emissions and perform fuel substitution tests for all measures that involve adding or replacing equipment that uses refrigerant and involves a change to the refrigerant type or to the refrigerant charge —these include most fuel substitution and electric resistance to heat pump measures. The completed RACC-FSC_v3.0—containing the relevant parameters associated with a given measure package—shall be provided as an addendum to each affected measure package in the eTRM. Guidance for how to do so is described in the “RACC-FSC Technical Guidance Document” that was issued along with the RACC-FSC_v3.0 workbook. 

Measure Package Update Type

ACC Version

New offering(s) added to existing approved measure package for PY2024-2025

ACC2022 values shall be used in RACC-FSC for new offering permutations, only

Mid-cycle updates to existing approved measure packages for PY2025

ACC2022 values shall be used for all permutations

Measure package updates for PY2026

ACC2024* values shall be used for all permutations

New measure packages for PY2026

*As of the issuance of the RACC-FSC_v3.1, the 2024 ACCs have not been finalized.
