About the census

What BuildingCensus is

The US has roughly 5.9 million commercial buildings (EIA CBECS). For most of them, energy performance is nobody's business but the owner's. In about 50 jurisdictions, though, a benchmarking-disclosure law makes it a public record— large buildings must report their energy use every year, and the city or state publishes the results. That disclosed slice is the entire public record of US building energy performance, and BuildingCensus's job is to carry all of it.

Each jurisdiction publishes its own spreadsheet on its own portal, with its own columns and its own quirks. The data is public; it just isn't usable: no unified pages, no grades at a glance, no year-over-year record, nothing an owner, tenant, broker or retrofit contractor can link to.

BuildingCensus is the unified census of that record: one page per disclosed building with its ENERGY STAR score and letter grade, site and source energy-use intensity, greenhouse-gas emissions and intensity, floor area, vintage and the full multi-year disclosure history — cross-linked to its jurisdiction, its property type and its compliance context (Local Law 97 caps in New York, BERDO and BEPS elsewhere). Provenance and freshness are first-class: every figure traces to a government's official disclosure file, and jurisdictions whose data isn't public yet are listed as exactly that.

Frequently asked questions

What is building energy benchmarking?

About 50 US cities, counties and states legally require large buildings (typically over 20,000–50,000 sq ft) to measure and disclose their annual energy use through EPA's ENERGY STAR Portfolio Manager. The disclosures — ENERGY STAR scores, energy-use intensity and greenhouse-gas emissions — become public records. BuildingCensus unifies them into one page per building.

Why isn't every US commercial building here?

The US has roughly 5.9 million commercial buildings (EIA CBECS), but energy performance is only a public record where a benchmarking-disclosure law makes it one — and those laws cover only large buildings in the jurisdictions that have them. BuildingCensus tracks the entire disclosed record: 142,435 buildings across 24 jurisdictions, growing as more jurisdictions publish.

Which jurisdictions require building energy disclosure?

BuildingCensus covers 24 live jurisdictions — including New York City (LL84), California's statewide AB 802 program, Los Angeles, Washington DC, Boston (BERDO), Chicago, Seattle, San Francisco, Philadelphia, Denver, Atlanta and Miami — 142,435 buildings in all. 22 more jurisdictions have disclosure laws whose data is queued or not yet published; see the coverage page.

What is a good ENERGY STAR score?

ENERGY STAR scores run 1–100 and represent a percentile against similar buildings nationwide — 50 is median and 75+ qualifies a building for ENERGY STAR certification. BuildingCensus bands scores like a report card: A (85–100), B (70–84), C (55–69), D (below 55).

Which building emits the most carbon?

Among disclosed buildings, the largest reported emitter is Coresite Sv8 in California at 27,420,510 tCO₂e in its latest disclosure year. See the biggest-emitters ranking for the full list.
