This dataset has the following 31 columns:

Column NameAPI Column NameData TypeDescriptionSample Values
ENERGY STAR Unique IDpd_idnumberThe ENERGY STAR Unique ID (ESUID) is a string of seven numbers EPA assigns to an ENERGY STAR model or set of models with unique performance characteristics. This ESUID is unique to both the model and product specification version and is assigned by EPA upon receipt of certification information from the certification body. Each row within the product list will have a unique ESUID. Developers may wish to use this ESUID to track information on certified models in their information systems.
ENERGY STAR Partnerenergy_star_partnertextAn organization that signed a Partnership Agreement with EPA to manufacture or private label ENERGY STAR qualified products.
Brand Namebrand_nametextAn identifier assigned by the manufacturer or private labeler to a product or family/series of products for sales and marketing purposes.
Model Namemodel_nametextAn identifier assigned by the manufacturer or private labeler to a product or family/series of products for sales and marketing purposes.
Model Numbermodel_numbertextA distinguishing identifier, usually alphanumeric, assigned to a product by the manufacturer or private labeler.
Additional Model Informationadditional_model_informationtextThis column includes for the qualified model or family, family members, additional model names, model numbers and other identifying information associated with a product or family/series of products for sales and marketing purposes. Other identifying information includes, but is not limited to, SKUs, UPC codes, retail numbers, and/or descriptions of models included/not included in the reported Model Family.
Typeunit_typetextThe type of ventilating fan.
Number of Speedsnumber_of_speedstextThe number of speeds available for a ventilating fan. For fans with three or more speeds, only 3 is displayed.
Sound Level (sones)sound_level_sonestextResidential bath and utility ventilating fans and range hoods must meet maximum allowable sound levels between 2-3 sones. There are no sound requirements for single or multi-port in-line fans.
Airflow 1 (cfm)airflow_1_cfmnumberIt is standard industry practice to round down airflow to the nearest 10 cfm when publishing this metric in product directories as the Airflow Certified Rating. For this reason, Airflow Certified Rating and As-Tested Airflow may occasionally differ on this list. In the case of a range hood, Airflow Certified Rating represents performance at working speed, while in the case of a bathroom or utility room fan, or an in-line ventilating fan, it represents maximum speed.
Airflow 2 (cfm)airflow_2_cfmnumberIt is standard industry practice to round down airflow to the nearest 10 cfm when publishing this metric in product directories as the Airflow Certified Rating. For this reason, Airflow Certified Rating and As-Tested Airflow may occasionally differ on this list. In the case of a range hood, Airflow Certified Rating represents performance at working speed, while in the case of a bathroom or utility room fan, or an in-line ventilating fan, it represents maximum speed.
Airflow 3 (cfm)airflow_3_cfmnumberIt is standard industry practice to round down airflow to the nearest 10 cfm when publishing this metric in product directories as the Airflow Certified Rating. For this reason, Airflow Certified Rating and As-Tested Airflow may occasionally differ on this list. In the case of a range hood, Airflow Certified Rating represents performance at working speed, while in the case of a bathroom or utility room fan, or an in-line ventilating fan, it represents maximum speed.
Efficacy 1 (cfm/Watt)efficacy_1_cfm_wnumberEfficacy is calculated by using airflow and fan motor electrical power values as tested per the requirements of this specification. Fan motor electrical usage is the only energy consumption considered for the fan efficacy calculation. Energy used for other fan auxiliaries (e.g., lights, sensors, heaters, timers, or night lights) is not included in the determination of fan efficacy.
Efficacy 2 (cfm/Watt)efficacy_2_cfm_wnumberEfficacy is calculated by using airflow and fan motor electrical power values as tested per the requirements of this specification. Fan motor electrical usage is the only energy consumption considered for the fan efficacy calculation. Energy used for other fan auxiliaries (e.g., lights, sensors, heaters, timers, or night lights) is not included in the determination of fan efficacy.
Efficacy 3 (cfm/Watt)efficacy_3_cfm_wnumberEfficacy is calculated by using airflow and fan motor electrical power values as tested per the requirements of this specification. Fan motor electrical usage is the only energy consumption considered for the fan efficacy calculation. Energy used for other fan auxiliaries (e.g., lights, sensors, heaters, timers, or night lights) is not included in the determination of fan efficacy.
Lighting Technologylighting_technology_usedtextThe light source technology utilized by the fixture: compact fluorescent light (CFL), light emitting diode (LED), or halogen.
Total Light Output (lumens)light_output_lumensnumberThe amount of light emitted by the light source or light fixture. Non directional fixtures (with removable light sources i.e. GU24 base bulbs) are measured at the light source and do not account for light lost from the fixture, while other fixtures meant to put light on a specific application (e.g. recessed downlights, under cabinet lights, accent lights, cove lights) are measured at the fixture level, only counting the light that escapes the fixture.
Total Input Power (Watts)total_input_power_wattsnumberTotal power consumed by the luminaire while in use.
Energy Efficiency - Measured Outside the Fixture (lm/W)luminaire_efficacynumberThe quotient of the total luminous flux (lumens) emitted by the fixture over the total power input (Watts). It is expressed in lumens per watt (lm/W). For ENERGY STAR qualified fixtures this applies to light fixtures that are considered directional and are measured at the fixture level. This includes the following residential grade directional fixture types: line-voltage track lights, ceiling fan light kits, undercabinet and cove lighting, downlights, recessed, pendant or surface mounted and includes retrofit kits for existing recessed cans. This also includes the following LIMITED commercial fixture types: Accent lights such as line-voltage track lights, under cabinet task lights, portable desk task lights, downlights, recessed, pendant or surface-mounts BUT EXCLUDES typical commercial and industrial fixtures such as recessed troffers or linear forms (e.g. linear fluorescent pendants) typically used in office spaces.
Power Factorpower_factornumberRatio of real power flowing to the lamp to the apparent power in the circuit. A lamp with a lower power factor will draw more current than a lamp with a higher power factor of the same wattage.
Light Color Appearance (CCT)correlated_color_temperature_kelvintextA description of the "color" of a light source measured on the Kelvin (K) scale. CFLs are available in a range of color temperatures. Lower values (2700-3000K) mean the white light has a warmer (red-yellow) tone, while higher kelvin (4100-6500K) mean the white light has a cooler (bluer) tone.
Light Color Quality (CRI)color_rendering_index_crinumberMeasure of the degree of color shift objects undergo when illuminated by the light source as compared with the color of those same objects when illuminated by a reference source of comparable color temperature.
Light Source Life (Hours)life_source_life_hoursnumberThe expected useful life of the light source. Measured differently depending on the technology of the light source. For example, LED lighting expected useful life is based on the estimated point at which only 70% of the original light output remains, while for older technologies, like fluorescent and halogen, estimated useful life is based on the measured median sample life.
Special Features (Dimming, Motion Sensing, etc.)special_features_dimming_motion_sensing_etctextMost fixtures are designed to operate on an on/off switch. However, some fixtures have been designed with features to perform in specialized applications, such as with dimmers, three-way, or photo cell controls. Special features and compatibility with controls should be clearly marked on the product packaging, cut sheet or web site for the product.
NotesnotestextIndicates information on certification relevant to the consumer (i.e. product variations, unique issues concerning the model’s listing, etc.).
Date Available On Marketdate_available_on_marketcalendar_dateThe date that the model is available for purchase.
Date Qualifieddate_qualifiedcalendar_dateThe date on which the product was confirmed to meet the ENERGY STAR specification.
MarketsmarketstextIncludes products sold in the U.S. and/or Canada and other ENERGY STAR partner countries.
CB Model Identifierenergy_star_model_identifiertextA unique string of characters assigned by certification bodies (CBs) to identify a model or set of models with the same performance characteristics. This identifier should remain the same for a model even if it is recertified to a new version of an ENERGY STAR specification. This string of characters is determined by CBs and is not the ENERGY STAR Unique ID assigned by EPA.
LightinglightingtextIndicates if the unit includes a light source.
