* Remove secondary heating and wood stoves from being subject to exogenous switching rates, as they were not intended to be covered by these rates. * Allow users to set ‘tech_switch_to’ to the value ‘same’ and have the code calculate a switchover to the same technology under exogenous switching rates. This is sometimes necessary for accounting purposes – for example, if exogenous rates are represented and a baseline segment is included that is subject to those rates, but without a complementary measure in the analysis to switch that baseline segment to, the results will show a decline in that baseline segment without a complementary increase in a switched to segment, thus under-representing that baseline segment’s influence on the total results. * Add ASHP to technology list where zero costs are expected (in EIA new construction data ASHP costs are zero for cooling, all costs are in the heating end use.) * Remove water services as a distinct technology type as it appears to be counted already under “unspecified” (see issue #394). * Refactor calculation of hourly TSV load adjustment factors to ensure that each end use in the tsv_load.gz data will be leveraged (previous approach had resulted in skipping some edge case end uses in those data like clothes washing, pool pumps and pool heaters that are under ‘other’ in the Scout data). * Ensure that once cumulative measure-captured or cumulative competed stock fractions reach 1 in a given modeling year, these fractions are not updated in any subsequent years of the modeling time horizon. * Improve warning message for units conversion issues. * Add measure JSON check to ensure that measures that are set to fuel switch to electricity apply to non-electric fuels in the baseline.

From @jtlangevin, there appear to be three separate accounting issues.
Further investigation shows that for item 2, both "water services" and "telecom systems" are double-counted. |

Update handling of commercial energy use data to address the three problems identified in issue #394: (1) for all commercial building types except 'unspecified,' the MELs technology type 'other' double-counts electricity use from all other specific MELs technologies; (2) for the 'unspecified' commercial building type, the 'unspecified' electric end use double-counts electricity use from the specific MELs technologies 'water services' and 'telecom systems;' and (3) energy use for fuels other than natural gas and distillate are not included for commercial buildings. Update stock and energy data files with revised values to incorporate these changes.

Per this spreadsheet check it appears that ~0.7 quads of what's currently under the commercial fuel type
electricityend useMELsand technologyotheris actually non-electric energy use (in AEO, it's under the fuel types distillate, residual, LPG, steam coal, motor gas, and kerosene - so should probably be assigned todistillatein the Scout data). Also, it appears that Scout's electricity use for theunspecifiedbuilding type is double counting water services under both theunspecifiedandMELs->water servicesend uses, ~0.3 quads.As a result, the Scout commercial electricity totals are about a quad higher than they should be, while the commercial non-electricity totals are ~0.7 quads lower.
This has important implications for full sector emissions and electricity analyses (electric loads overstated, emissions from non-electric end uses understated).
