Ventilation Fans Purchasing & Procurement Language

What ENERGY STAR Purchasing & Procurement resources does EPA offer?

ENERGY STAR Purchasing & Procurement resources include lists of qualifying products, key product criteria, drop-in procurement language and savings calculators. Organizations can use these resources to facilitate the procurement of energy-efficient ENERGY STAR products and prevent greenhouse gas emissions.

The following is an example of language you may wish to require in your upcoming contract:

The Vendor Must:
Provide ventilation fans that earn the ENERGY STAR and meet the ENERGY STAR specifications for energy efficiency as outlined below. The vendor is encouraged to visit www.energystar.gov for complete product specifications and an updated list of qualifying products.

The following products may qualify as ENERGY STAR:

  • a. Residential ventilating fans with no light source
  • b. Combination unit residential bathroom and utility room ventilating fans having a light source that meets the lighting performance criteria listed in Table 2, below. Residential bath and utility ventilating fans that have lamp sockets that can accept incandescent lamps are excluded.
  • c. Range hoods with incandescent light sources or sockets (through December 31, 2004).
Criteria for ENERGY STAR Qualified Residential Ventilating Fans
  Airflow (cfm) Minimum Efficacy Level (cfm/W)* Maximum Allowable Sound Level (Sones)*
Range Hoods up to 500 cfm (max) 2.8 2.0
Bathroom and Utility Room Fans 10 to 80 cfm 1.4 2.0
Bathroom and Utility Room Fans 90 to 130 cfm 2.8 2.0
Bathroom and Utility Room Fans 140 to 500 cfm (max) 2.8 3.0
In-Line (single-port & multi-port) Ventilating Fans   2.8 N/A

All qualifying vent fan models, with the exception of in-line and range hood models, when measured by industry standard testing procedures at 0.25 in. w.g. static pressure, shall deliver a rated airflow (cfm) equal to or greater than the following percentages of rated airflow delivered at 0.1 in. w.g. static pressure for that particular model:

Product Category Rated Airflow (0.25 in. w.g.)
Bathroom and Utility Room Fans — 10 to 80 cfm 60%
Bathroom and Utility Room Fans — 90 to 130 cfm 70%
Bathroom and Utility Room Fans — 140 to 500 cfm 70%
Light Source Criteria
System Efficacy per lamp ballast combination, Lumens Per Watt (LPW) — see notes at end of this table

>= 46 LPW for all lamp types below 30 total listed lamp Watts.

>= 60 LPW for all lamp types that are >= 24 inches and >= 30 listed lamp Watts.

>= 70 LPW for all lamp types that are >= 24 inches and >= 30 listed lamp Watts.
Lamp Start Time The time needed after switching on the lamp to start continuously and remain lighted must be an average of one second or less.
For manufacturers using magnetic ballasts and lamps with integrated electronic starting chips, lamps must be included with the residential ventilating fan when shipped from the factory.
Lamp Life For residential ventilating fans that are shipped with a lamp, the average rated life of the lamp must be $ 10,000 hours.
Color Rendering Index >= 80 for compact fluorescent lamps.
>= 75 for linear lamps.
Correlated Color Temperature For residential ventilating fans that are shipped with a lamp and do not have a rated color temperature of 2,700 Kelvin (K) or 3,000 K (actual measured CCT of 2,700 to 3,000K += 200K), the packaging should clearly describe the color of the product (cool or warm) and state its intended use.
Noise Class A sound rating for electromagnetic and electronic ballasts, outside the fixture. Not to exceed a measured level of 24 dBA when measured in a room with ambient noise no greater than 20 dBA.
Maximum Total Lamp Wattage (excluding night lights) <= 50 Watts
Maximum Night Light Wattage <= 4 Watts

Notes:

  • Light Source efficacy shall be determined by the following equation: Light Source efficacy [Lumens per Watt] = Measured Lamp Lumens [Lumens]/Measured Input Power [Watts]
  • Lamp Lumens: Lamp lumens must be measured using the lamp and ballast that are shipped with the residential ventilating fan.
  • Light Source Input Power: Light Source input power must be measured using the lamp and ballast that are shipped with the residential ventilating fan.
  • For residential ventilating fans shipped without lamps
    • efficacy shall be determined by testing at least one of the lamp types listed on the product packaging.
    • a list of lamp types must be provided that would result in the lighting source complying with this specification requirement. This list must be clearly visible to the consumer on the residential ventilating fan packaging. Manufacturers are not required to provide specific lamp manufacturer names and model numbers on the packaging. Rather, generic lamp listings, such as the NEMA or ANSI generic descriptions will suffice.
  • In some cases, original equipment manufacturers (OEMs) may already offer lamps and ballasts that meet the above criteria. Manufacturers may choose a lamp/ballast combination from the NEMA/ALA matrices at http://www.nema.org/lampballastmatrix/index.html Exit ENERGY STAR or data from an ENERGY STAR Platform Letter of Qualification supplied by the OEM.
