These fans also provide continuous, whole-house ventilation which is becoming increasingly popular and continually removes contaminants generated in homes every day. Continuous ventilation – also known as whole-house ventilation – is being required to meet building codes such as California Title 24, or green building standards such as LEED or ENERGY STAR® for Homes. These types of programs reference the ASHRAE 62.2 residential ventilation standard that details the amount of air in cubic feet per minute (CFM) needed for whole-house ventilation, based on square footage and the number of bedrooms in the home.
Choosing an ENERGY STAR® qualified fan is always a good idea, but it is even more important for whole-house fans that may run all the time. ULTRA™ Series Ventilation Fans with ULTRA Green™ DC Motor Technology greatly exceeds ENERGY STAR® CFM-per-watt requirements; for example the 80 CFM fan models at 5.8 watts are almost 10 times more efficient than ENERGY STAR® requirements.
The exclusive ULTRA Smart™ Control Technology enables these fans to maintain their powerful operation even at high static pressures (resistance to airflow through a duct system), and supply the required air movement levels for whole-house ventilation while meeting the spot ventilation needs of a bathroom. This control technology continually monitors the fan’s performance and adjusts the motor speed to ensure the air movement expected is delivered in nearly every installation. Additionally the continuous lower CFM adjustment dial allows you to precisely set the airflow as low as 30 CFM which means there is no costly over-ventilating or unhealthy under-ventilating. ULTRA™ maintains powerful operation over a wide range of real-world installations, maintaining 0.1” static pressure CFM ratings to 0.25” and usually well beyond.
In the midst of the Great Depression, two aggressive young men emerged with two new products that would make major contributions to the housing industry. In 1932, Henry Broan developed and manufactured a kitchen fan called the Motordor® Fan that provided quiet and efficient kitchen ventilation. His creation launched what is today known as Broan-NuTone LLC. Four years later, in 1936, J. Ralph Corbett developed a melodious door chime replacing the obnoxious door buzzer of the time. His development launched what is today known as NuTone, Inc. Both men, headquartered in the Midwest, started their companies with a simple product and a few employees. Each expanded their companies, creating revolutionary new products that provided unmatched conveniences for homeowners nationwide. Both companies quickly became global competitors and continued to provide innovative, superior products to meet the needs of consumers. In 1981, Broan Mfg. Co., Inc. was acquired by Nortek, Inc. and became the lead company of Nortek's Residential Building Products Group, which was named the Broan Group. During this same time period, NuTone was sold to Scovill Manufacturing in 1967 and was then acquired by Williams plc in 1991. In 1998, Nortek acquired NuTone, adding it to the Broan Group and renaming the group the Broan-NuTone Group. Then, in January 2000, Broan Mfg. Co., Inc. became Broan-NuTone LLC. Today, Broan-NuTone LLC leads the industry with forward-thinking residential ventilation products, customized climate, communications and storage solutions and superior customer service. Broan-NuTone is proud to acknowledge that over 80% of homeowners in the United States rely on one or more BROAN®, NuTone®, or BEST® products every day to provide them with superior indoor air quality and lifestyle conveniences. Headquartered in Hartford, Wisconsin, Broan-NuTone employs 2,600 people in eight countries on five continents. Other manufacturing, marketing and sales locations include Ohio, California, Canada, Italy, Chile, Australia, Poland, China and Mexico. Broan-NuTone’s inspiring heritage provides the foundation for its three global brands – BROAN®, NuTone® and BEST®. BROAN® is the industry leader of range hoods, ventilation fans, heater/fan/light combination units, Indoor Air Quality (IAQ) Fresh Air Systems, built-in heaters, whole-house fans, attic ventilators and trash compactors. NuTone® holds major market positions in door chimes, central vacuum systems, stereo intercom systems, ironing centers, ceiling fans and ventilation fans. BEST® range hoods are the “Ultimate in Kitchen Ventilation” featuring state-of-the-art performance and Italian design. Broan-NuTone is committed to developing revolutionary products that improve the indoor environment as well as implementing procedures to preserve the outdoor environment. Broan-NuTone offers a wide selection of products that help meet the requirements of all three major green building programs: ENERGY STAR®; U.S. Green Building Council’s (USGBC) Leadership in Energy and Environmental Design (LEED) for Homes; and the National Association of Home Builder’s (NAHB) Model Green Home Building Guidelines.
