Quiet and Efficient Vent Fans
The good news is that the options for quiet and efficient vent fans are growing.There are now over 150 qualified models on the EPA’s Energy Star product list (see “Energy Star Specification”). These include bathroom/utility vent fans, inline fans, and kitchen range hoods. A key feature of these qualified models is noticeably quieter operation, making it much more likely that homeowners will use them. In fact, an efficient, high-quality, vent fan can be a selling point to a potential home buyer. More and more contractors and homeowners are recognizing the benefits of these products, and manufacturers are making more models accessible to consumers.
Vent Fan as Selling Point
A rule of thumb in real estate is that kitchens and bathrooms receive the most scrutiny from potential home buyers. An otherwise positive first impression of a home can be ruined at the flip of a switch—if a loud vent fan comes roaring to life. Rather than walking potential buyers through a house while fearing that they will switch on a noisy bath fan, builders can show the bathroom and point to the quiet fan as an added benefit. When home buyers learn that the fans will also save them money through reduced electricity bills, they are further impressed (see Table 1).
One of the more notable success stories from contractors using Energy Starqualified fans comes from Walter Rodriguez of Master Cooling Corporation.“ The fans can even be a selling point for builders,” says Rodriguez. Prior to his most recent project, phase 2 of the Arverne by the Sea townhouse community in Queens,New York, Rodriguez had used only standard- efficiency models. Since the homes at Arverne were designed to be high-performance houses, with characteristically tighter building envelopes, Rodriguez wanted to be sure that they would receive adequate ventilation and so placed the fans in some bathrooms on automatic timers to run periodically throughout the day. Knowing that homeowners would not tolerate standard, noisy fans, Rodriguez looked for alternatives and found Panasonic’s Whisper Series line of fans. In addition to offering ultra-low sone levels (0.4 and 0.8 sones for the models selected for Arverne, compared to an industry average of over 2.5 sones), the fans also offered energy savings of up to 65%.
After testing a few of the fans, Rodriguez was convinced. “I was really shocked. It really is a better product. The 8-inch Panasonic fan is quieter than a 4- inch [standard] fan.” He decided to specify this model for all phase 2 bathroom and kitchen fans—not just those on timers.With six vent fans per unit in all 1,200 homes, each homeowner in Arverne will save about $19 per year, for a communitywide annual savings of approximately $23,000.
Sylvain Côté of Absolute Remodeling has found that Energy Star-qualified inline fans produced by Fantech provide energy savings as well as the traditional benefits of inline fans. Traditionally used in higher-end projects, inline fans provide extra flexibility and performance. Because the fan is remotely mounted, often in the attic, noise from inline fans is often muffled by the ductwork, so they tend to be less noisy than standard fans. In addition, multiport models allow multiple rooms to be ventilated by a single motor. Using Fantech’s qualified models in nearly all of his kitchen and bath projects, Côté strives to provide his clients with “the best product on the market.” How do his customers react to their new exhaust fan? “They all love it. Everybody is used to the noisy fans we have had to endure. These are just so much different.” Energy Star-qualified inline fans cost about the same as standard- efficiency alternatives, but they use about 25% less energy.
Retail Availability Growing
One of the biggest names in the market, Broan-NuTone has 85 models on the Energy Star-qualified list. Models in their QT series are now available at Lowe’s and The Home Depot, among other retail outlets. As they got ready to introduce their QT series at these stores, Broan-NuTone modified packaging and display bays to prominently identify the qualified products.
In place of a 100W incandescent bulb, the models with integrated lighting use a 26W pin-based CFL. (For more on Energy Star fans with light fixtures, see “Advanced Lighting Package.”) These models currently employ magnetic ballasts, but Broan-NuTone is in the process of converting all of its Energy Star-qualified models to include electronic ballasts. Utilities in the states of Massachusetts, Rhode Island, and Connecticut are treating these fans as qualifying light fixtures for Interior Light Fixture incentives.Vent fans should be added to the next round of instant coupons (worth $10–$15,depending on the jurisdiction) delivered to stores.
Energy Star Range Hood Makes Its Debut
The newest addition to the Energy Star family of ventilation products is the first qualified kitchen range hood. The Deluxe 4000-250ES range hood by Reversomatic provides an efficacy of 2.92 CFM/W at 140 CFM and meets the 2-sone maximum noise level limit. This constitutes a 62% reduction in power consumption and makes the 4000-2500ES range hood 70% quieter than standard models. Like many other Energy Star-qualified products, the Reversomatic range hood, at a cost of $300–$450 depending on the size and flow rate, is priced competitively with other midrange units.
