RATINGS FOR QUALITY, QUIETNESS This directory lists the only ventilating fans, which offer a complete and uniform basis for comparison and rated performance – those, which bear the HVI Tested/ Certified Label. Listed herein are range hoods, wall and ceiling exhaust fans, whole house fans and powered attic space ventilators, which conform to HVI's standards. All HVI ratings for fans are based on independent tests at HVI approved laboratories. Each fan is tested under specific air resistance and other conditions related to actual application, as distinct from "free air" or other nonstandard conditions. Indoor fans carry dual ratings, for quietness as well as ventilating performance. Simple validated numbers tell the air movement in CFM (cubic feet per minute) and the sound output in sones. Exterior-mount ventilators, usually ducted to the kitchen, offer high capacity and quietness. Whether their tasks are removal of the odors, fumes, smoke, moisture and heat of indoor air pollution or automatic removal of summer heat and winter moisture from attics, fans with the HVI Label can be depended on to exhaust the amount of air for which they are rated. All are true ventilators, as distinguished from recirculating devices. HVI lists ratings in steps of 10 CFM and 0.5 sones. Fans of multiple speeds must be rated for sound at maximum CFM ratings and may be rated also at lower CFM levels. Sone ratings permit easy and accurate comparisons of exhaust fans tested under identical laboratory standards and conditions. A fan rated at 3 sones makes half the sound of one of 6 sones, just as 100 CFM is half the air movement of 200 CFM. For adequate ventilation, the Home Ventilating Institute recommends these guidelines for air changes with wall or ceiling exhaust fans: kitchen, 15 changes an hour; bathroom, 8; family, recreation or laundry room, 6. To calculate the CFM capacity of wall or ceiling fan which will deliver the needed air movement, multiply floor area by the appropriate factor, as follows (assuming an 8-foot ceiling): kitchen, 2; bathroom, 1.07; family, recreation or laundry room, 0.8. A different basis for selection applies to range hood fans. Recommended minimums: 40 CFM per lineal foot of range hood for along-wall placement. Higher ratings than minimums often are desirable. VENTILATION GUIDELINES The recommended minimum capacity for whole-house fans is based on the HVI guideline, which requires one complete air change every two minutes within the occupied area. This may be determined by multiplying the gross square footage of the entire house (including non-occupied areas like closets) by 3. Be sure to include the "upstairs" area of multilevel homes. This formula assumes an 8' ceiling and offsets typical non-occupied areas. For powered attic space ventilators, HVI guidelines are minimum of 0.7 CFM per square foot of attic floor space, plus 15% for dark roofs, and intake area of 1 square foot of free opening per 300 CFM of fan capacity. Ratings are based on testing of complete roof or gable units at .03" static pressure. WHAT’S A SONE? The sone is an internationally recognized unit of loudness, which simplifies reporting of sound output. The sones translate laboratory decibel readings into numbers that correspond to the way people sense loudness. Sones follow a “linear” scale, like inches. Double the sone is double the loudness. In contrast, decibels follow a “logarithmic” scale, which stands for a complete multiplying of numbers instead of simple adding. Sone readings offer easy, quick and accurate comparisons for both laymen and engineers. In technical terms, the sone is equal is loudness to a pure tone of 1,000 cycles per second at 40 decibels above the listener’s threshold of hearing. In everyday terms, one sone is equivalent to the sound of a quiet refrigerator in a quiet kitchen. Regarding sound levels of Exterior Mount and In-line Fans, and HRV’s/ERV’s: HVI, the Home Ventilating Institute, does not certify Sound Ratings for Exterior Mount and In-line fans, and Heat/Energy Recovery Ventilators. Remote mounted fans can be extremely quiet if installed properly. Although different fans produce different amounts of sound power, variations in installation yield significantly greater differences in perceived sound level for remote mounted fans. As is the case with furnaces, rating remote mount fans for sound does therefore not make sense. For bathroom and other exhaust or supply air applications using remote mount fans, HVI recommends using insulated flexible ducting (same as used for HVAC ducting). Insulated flexible ducting has very good noise attenuating properties and minimizes condensation. With eight feet of insulated flexible duct between the ceiling grill and the fan, almost no fan noise should be evident in the bathroom. Ensure that the ceiling grills are large enough not to induce significant air noise. For bathroom applications an automatic timer is a recommended in order to keep the fan from being left on inadvertently. For range hood exhaust rigid metal duct shall always be used. Rigid ducting does not attenuate sound effectively. With the very powerful remote mount fans often used for residential range hoods in “professional” style kitchens, a silencer designed for the purpose will significantly lower the sound level.
