open-bps 0.2.0

New jurisdictions, your own portfolio, retrofit underwriting. Every 0.1.0 interface and output is unchanged.

Jurisdictions

• Policy registry. The rule files moved to open_bps/jurisdictions/ and are validated by a Pydantic
  JurisdictionPolicy. rules.load() still returns the 0.1.0 dicts.
• NYC Local Law 97: 1 RCNY §103-14 limits for 60 property types and 5 periods, with DOB coefficients.
  The engine reproduces DOB's worked examples. A scored LL84 dataset is added.
• Boston BERDO 2.0: Table 1 standards, the Appendix A type map, projected grid factors, RPS shares and
  the ACP. A scored disclosure dataset reproduces the city's verdicts for 901 of 901 buildings.
• Mixed-use buildings: blending for NYC's floor-area-weighted limit, and for Boston's default and opt-in
  blend.
• Generic GHG engine. A fuel or property type the rule cannot price is flagged, never estimated.

Your own buildings

• Inputs: BuildingRecord and PortfolioInput with row-level errors, and an ENERGY STAR Portfolio Manager
  adapter.
• Underwriting: avoided penalties, energy savings and §179D (gated at a 2026-06-30 construction start),
  financed with C-PACE, debt or cash. Results are NPV, IRR and payback, with a statutory or cleaner-grid
  scenario.
• Workbooks: an Underwriting sheet, and a multi-building portfolio workbook. Every figure is a live formula,
  reconciled on the Checks sheet.

Tools

• open_bps.PortfolioAnalyzer and open-bps analyze.
• An MCP server, open-bps-mcp (pip install "open-bps[mcp]").
• The app has a portfolio underwriting tab, and streamlit run app.py works.

pip install -U open-bps            # or "open-bps[mcp]" / "open-bps[app]"
