v0.7.1 (2022-01-31)

What's New

v0.6.1 (2021-09-28)

What's New

• Add state-level breakouts of baseline data and electricity emissions and costs
• Update EMM regions and default peak/take periods to AEO 2020, support regional emissions intensity/electricity price calculations
• Rework the nature of measure packages with a focus on handling interactions between HVAC equipment, envelope, and controls
• Support calculation of sector shape and time-sensitive valuation data for packages and fuel switching measures
• Improve stock turnover calculations and measure cost-effectiveness calculations throughout
• Add several new user options, including:
  • Select an alternate grid scenario consistent with full grid decarbonization by 2035
  • Impose exogenous fuel switching conversion rates to determine fuel switching measure market shares
  • Breakout results by fuel type (electric/non-electric) for heating, water heating, and cooking measures and packages
  • Specify measure performance and/or cost by IECC climate zone in addition to AIA climate zone
  • Restrict simulations to a single adoption scenario (max adoption potential or technical potential)
  • Impose a global measure market entry year (e.g., the first year in which any of the measures can have an impact)
  • Suppress calculation of secondary lighting impacts for commercial buildings
