    - NYC Building Energy and Water Data Disclosure for Local Law 84 2023 to Present (Data for Calendar Year
      2022-Present), Department of Buildings, dataset 5zyy-y8am, records with report_year 2024 (calendar year 2024),
      as published on 25 November 2025.
      https://data.cityofnewyork.us/d/5zyy-y8am
      Changes: child records whose parent record is present left out; records not existing or unoccupied, with no
      floor area by use, no energy, or site energy per square foot under 5 or over 1,000 kBtu left out; emissions,
      limits and penalties worked out as described in README.md; flags added.
    - Primary Land Use Tax Lot Output (PLUTO), Department of City Planning, dataset 64uk-42ks, version 26v2.
      https://data.cityofnewyork.us/d/64uk-42ks
      Used for each property's community district, position (latitude and longitude), owner type and owner name
      (to flag buildings likely on another compliance pathway). Owner names are not republished.
    - Community Districts, Department of City Planning, dataset 5crt-au7u.
      https://data.cityofnewyork.us/d/5crt-au7u

    - BUILDING (Building Footprints), Office of Technology and Innovation, dataset 5zhs-2jue.
      https://data.cityofnewyork.us/d/5zhs-2jue
      Changes: footprints in Manhattan Community District 5 matched to benchmarked properties by BIN, then by lot;
      roof height converted from feet to metres.

  The rules (public law, quoted, not licensed): Local Law 97 of 2019, NYC Administrative Code Title 28 Article 320
  (28-320.3.1.1 greenhouse gas coefficients for 2024 to 2029; 28-320.6 penalties), and the Department of Buildings
  rule 1 RCNY 103-14 (emissions factors by Energy Star Portfolio Manager property type, (c)(3)(i) and (iii);
  coefficients for 2030 to 2034, (d)(3)). The penalty of $268 per tonne over the limit and the 2024 to 2029
  coefficients are as stated by the Department of Buildings in "Local Law 97: Calculating Building Emissions &
  Emission Limits" (26 June 2024).
