NYC Building Energy and Water Data Disclosure for Local Law 84 2023 to Present (Data for Calendar Year 2022-Present)
Local Law 84 of 2009 (LL84) requires annual energy and water benchmarking data to be submitted by owners of buildings with more than 50,000 square feet. This data is collected via the Environmental Protection Agency's (EPA) Portfolio Manager website Each property is identified by it's EPA assigned property ID, and can contain one or more tax lots identified by one or more BBLs (Borough, Block, Lot) or one or more buildings identified by one or more building identification numbers (BIN) Please visit DOB's Benchmarking and Energy Efficiency Rating page for additional information.

Columns
Each source column, with the name and type we use to store it.
4 of 265 columns carry a concept; 254 carry a description from the publisher. Read the concept column before you join. A column with no concept carries no claim from us, and a name that looks like a key is not one.

social_meeting_hall_gross | Social/Meeting Hall - Gross Floor Area (ft²) | "The Gross Floor Area (GFA) is the total “property” square footage, and a “property” can be a: Single building Campus of buildings Part of a building (such as a single tenant space). Depending on which above type you have, your exact GFA is determined differently: “Single buildings” and “campuses of buildings” measure the GFA between the outside surface of the exterior walls of the building(s). This includes all areas inside the building(s) including supporting areas. GFA is not the same as rentable space, but rather includes all area inside the building(s). Include in GFA: lobbies, tenant areas, common areas, meeting rooms, break rooms, atriums (count the base level only), restrooms, elevator shafts, stairwells, mechanical equipment areas, basements, storage rooms. Do not include in GFA: exterior spaces, balconies, patios, exterior loading docks, driveways, covered walkways, outdoor play courts (tennis, basketball, etc.), parking (How to enter parking?), the interstitial plenum space between floors (which house pipes and ventilation), crawl spaces. Although you do not include these areas in your GFA, you do include their energy use. Our algorithms assume buildings have outdoor usage, too. The GFA refers specifically to interior space. But, the energy use evaluated should be all the energy required to operate your building, which includes the energy used both inside and out. You may exclude the GFA of certain Property Uses, if they meet these 4 criteria (see this FAQ for details): The Property Use is less than 10% of the building’s GFA The Property Use is not a property type eligible to receive an ENERGY STAR score The Property Use is sub-metered so that both the Property Use’s energy consumption and GFA can be excluded The Property Use’s energy use patterns are significantly different than those of the rest of the building (ex: A cell phone tower on a building) “Parts of a building,” such as tenant spaces, measure the GFA of the “usable square feet.” Usable square feet include the specific area the tenant occupies to do business.
