v0.5 (2019-06-28)

What's New

• All baseline data and ECM definitions reflect EIA AEO 2019 reference case.
• Users may optionally specify site energy or captured source energy outputs.

v0.4.3 (2019-04-12)

What's New

• Updated and/or reorganized several ECM definitions.
• Fixed bugs in heat pump cost calculations, secondary lighting calculations, and time-sensitive valuation data.

v0.4.2 (2018-10-16)

What's New

• Added best available and prospective target ECM definitions.
• Enhanced time-sensitive efficiency valuation capabilities and underlying datasets.
• Small bug fixes, refinements to ECM stock-and-flow and competition calculations.

v0.4.1 (2018-07-13)

What's New

Fixed bugs with R v3.5, envelope/HVAC interactions

v0.4 (2018-06-29)

What's New

Baseline technology stock/energy and cost/performance/lifetime data now correspond to the EIA Annual Energy Outlook 2018 reference case.

Time sensitive efficiency impacts (load shifting, shaping, etc.) are piloted through a new ‘time_sensitive_valuation’ field in the ECM definition.

Several new miscellaneous loads are broken out in the baseline technology stock and energy data, allowing ECMs to be applied specifically to these new loads.

Users may now assign ECM-specific baseline retrofit rates as part of the ECM definition.

v0.3.1 (2018-04-25)

What's New

Fixed bug in calculation of captured stock’s relative performance.

v0.3 (2018-04-20)

What's New

Baseline envelope data were updated to reflect expected code-driven changes in typical envelope characteristics over time.

Users may now assess ‘add-on’ ECM types when comparable baseline technology cost, performance, and lifetime data are missing (as is often the case for ECMs affecting Miscellaneous Electric Loads (MELs)).

Default ECM definitions were updated to reflect the newest available performance standards.

Other updates:

• expanded time horizon to 2050,
• site-source conversions now reflect AEO 2017 and residential cost conversions now reflect RECS 2015,
• multiple bug fixes pertaining to the ECM preparation routine, stock-and-flow calculations, and plotting configuration,
• expanded XLSX data generation in the R plotting routine, and
• updates to the documentation that reflect the above changes.

v0.2 (2017-06-18)

What's New

Notable changes based on an initial round of beta testing feedback include:

• addition of a Quick Start Guide to the docs,
• execution of R plots from within the ‘run.py’ analysis engine module, and
• additional filtering options in ‘run_setup.py,’ the high-level simulation manager.

Baseline technology stock/energy and cost/performance/lifetime data now correspond to the EIA Annual Energy Outlook 2017 reference case: https://www.eia.gov/outlooks/aeo/.
