Update ECMs
Browse files Browse the repository at this point in the history 
Update residential and commercial ECMs across the Best Available, ENERGY STAR, and typical or minimum performance levels. Update market scaling fractions to match updates to Prospective ECMs using the latest RECS and CBECS data. Update electrification costs to use more recent field data sources. Remove panel and service upgrade costs from the Best Available upgrade level assuming that the high efficiency equipment alongside the included envelope upgrade is sufficient to avoid the need for panel and service upgrades when fuel switching. Introduce efficiency improvements with fuel switching in the cooking end use. Revise ENERGY STAR HPWH to break out 120V and 240V performance levels and corresponding costs for upgrading existing homes. Fix year typos in notes in Reference Case ASHP (RST) ECMs. Rename reference case ('Ref. Case') ASHP ECMs to minimum efficiency ('Min. Eff.') to be consistent with the technology performance level specified in the ECM.

Fix #274. Fix #320 by revising package_ecms.json to reflect removal of the 'Prospective Commercial Air Seal (New)' ECM with the envelope updates in v0.8.1.
