Look up ACRIS property transaction records for any NYC property — deeds, mortgages, satisfactions, liens, and ownership history. Use when the user asks who owns a building, when it last sold or for how much, or whether there are mortgages or liens against it. NYC only; for permits or violations use the DOB skills.
Look up Board of Standards and Appeals (BSA) variances and special permits for any NYC property. Use when checking whether a lot carries zoning relief — variances, special permits, appeals — that modifies its as-of-right envelope. NYC only; for base zoning controls use /zoning-analysis-nyc.
Look up DOB permit and job filing history for any NYC building — new-building, alteration, and demolition filings with status and dates. Use when the user asks what work was filed or permitted at an address, or to gauge renovation history during due diligence. NYC only; for open violations use /nyc-dob-violations.
Look up open and resolved DOB and ECB violations for any NYC building, with class, status, and penalty detail. Use when the user asks whether a building has violations, stop-work orders, or outstanding ECB penalties. NYC only; for housing-code violations use /nyc-hpd.
Look up HPD violations, complaints, and building registration for residential buildings.
Check if a NYC building is landmarked or in a historic district using LPC data.

Receives a brief describing a material or product category, searches the web for matching EPDs (Environmental Product Declarations), and returns a curated shortlist sorted by environmental impact. Selected EPDs are saved to the EPD Google Sheet — the same one used by /epd-parser and the other EPD skills.

Saved to EPD Google Sheet (42-column schema)
The user describes what they need EPDs for. A brief can be loose or specific:
Loose:
"I need concrete EPDs"
Specific:
"Looking for ready-mix concrete EPDs, 4000-5000 PSI, plants within 500 miles of NYC, GWP under 350 kg CO2e/m3"
Extract as many of these as the user provides. Don't ask for fields they didn't mention — work with what you have.
| Field | Examples |
|---|---|
| Material/product | Ready-mix concrete, structural steel, mineral wool insulation, carpet tile |
| CSI division | Division 03, Division 09, "all structural materials" |
| Performance specs | 4000 PSI, R-21, Class A fire rating |
| Geographic preference | Plants near NYC, manufactured in North America, European suppliers ok |
| GWP target | Under 350 kg CO2e/m3, below industry average, lowest available |
| Manufacturers | "Include Holcim and CEMEX", "no imported steel" |
| EPD type | Product-specific only, industry-average ok |
| Standard | EN 15804+A2, ISO 21930 |
| Certification | LEED v4.1 eligible, third-party verified |
Don't interview the user. If the brief is "concrete EPDs," that's enough to start searching. Clarify after showing initial results if needed.
Search the web for EPDs matching the brief. Use multiple targeted queries to cover different sources.
| Source | URL pattern | Notes |
|---|---|---|
| Building Transparency / EC3 | buildingtransparency.org | Largest EPD database. Requires authenticated API access (free professional account + API key). See notes below. |
| UL EPD Program | ul.com | Major US program operator. Product-specific EPDs. |
| NSF International | nsf.org | US program operator, strong in concrete/masonry. |
| SCS Global Services | scsglobalservices.com | US program operator. |
| Environdec (International EPD System) | environdec.com | Largest international registry. European + global. |
| IBU (Institut Bauen und Umwelt) | ibu-epd.com | German program operator. Strong in European products. |
| ASTM International | astm.org | US program operator (newer). |
| Manufacturer sites | varies | Major manufacturers publish EPDs on their sustainability pages. |

## EPD Research: Ready-Mix Concrete (4000 PSI, Northeast US)
### 1. ECOPact — Holcim
Plant: South Plainfield, NJ · GWP: 242 kg CO2e/m3
Declared Unit: 1 m3 · System Boundary: Cradle-to-gate
Program Operator: NSF · Reg: EPD-00123 · Valid: 2024-06-01 to 2029-06-01
LEED: Yes (product-specific, third-party verified)
PDF: [link]
Why: Lowest GWP in the region. ECOPact line is Holcim's low-carbon
concrete — uses SCM substitution. Plant is ~50 miles from NYC.
### 2. ProPaving 4000 — CEMEX
Plant: Yonkers, NY · GWP: 298 kg CO2e/m3
Declared Unit: 1 m3 · System Boundary: Cradle-to-gate
Program Operator: ASTM · Reg: EPD-00456 · Valid: 2023-11-01 to 2028-11-01
LEED: Yes
PDF: [link]
Why: Close to site. Higher GWP than ECOPact but still below NRMCA
industry average (~400 kg CO2e/m3 for 4000 PSI).

Which ones should I save to your EPD library?
When the user picks EPDs ("save 1, 3, and 5"), write them to the EPD Google Sheet using the 42-column schema.
If not already connected, ask for the Google Sheet ID or URL. This is a separate spreadsheet from the FF&E product library — EPD data has a different schema.
Write to the 42-column EPD schema. Set:
Parsed At — current ISO timestampSource — epd-researchNotes — the "Why" reasoning from the presentation + any caveatsTags — from brief context (e.g., "4000-psi, northeast, project-name")LEED Eligible — based on EPD type and verification statusSaved 3 EPDs to your library (rows 12-14).

Want me to compare these? Or search for more options?
The user may want to refine:
/epd-compare/epd-to-specsite:buildingtransparency.org web searches will not return results. If the user hasn't configured EC3 API credentials, tell them: "EC3 has the largest EPD database but requires a free API key from buildingtransparency.org (professional account with a business email). I'll search program operator registries and manufacturer sites directly instead." Then proceed with the other sources listed above — UL, NSF, Environdec, IBU, SCS, ASTM, and manufacturer sustainability pages all publish EPDs publicly./epd-parser extracts full data from the PDFs. If the user wants deep data from a found EPD, download the PDF and run /epd-parser.
