Represent state appliance regulations scenarios

[jtlangevin]

Competition across multiple potential measure adoption choices in run must consider additional, state-level regulations on certain types of appliances (e.g., CARB standards, NY gas ban).

Proposed approach:

• Create a database that lists assumed restrictions on fossil fuel use by state, building type/vintage (new/existing), fossil fuel type, end use, and start year, with applicability factors to map policies that only affect a portion of the state’s area.
  • Database could include rows for representing regulations across broad groupings of states (e.g., state = ”leading”; state= “usca”)
• In run module competition calculations for each baseline microsegment, use data from (a) to flag competing measures for characteristics that are prohibited under laws affecting appliances, e.g.:
  • Restricted fossil-based energy use in new buildings where the measure does not electrify.
• When a measure is flagged in (b) for a given competed microsegment:
  • Determine what fraction of the microsegment’s competition the measure should be excluded from (e.g., 100% ban or a ban that applies to X% of the state’s population/building energy)
  • Pass the fraction determined in (c.i) to the find_added_sbmkt_fracs function, which will remove that portion from competition and distributed it to other competing measures
