Building Codes Still Lag Behind Home Ventilation Needs<\/em>
\nBy: Jen Anesi<\/p>\n

Most states have yet to adopt the most current residential building codes. And, while current residential
\nmodel building codes require higher ventilation rates and energy-efficiency requirements than ever
\nbefore, they still lag behind commercial codes.<\/p>\n

\u201cYou don\u2019t have universal code acceptance like you do on the commercial side, and there\u2019s no universal
\nacceptance of ASHRAE Standard 62.2 in any of the codes,\u201d said Drake Erbe, chair of ASHRAE Standard
\n90.1 and vice president of market development at Airxchange\u00ae Inc. \u201cSo, while you might have 62.2-2001,
\nyou don\u2019t have the most current version being adopted.\u201d<\/p>\n

Still, increasingly demanding standards and regulations are having a clear impact on the energy efficiency
\nand effectiveness of products used in residential ventilation and air movement, including fans, dampers,
\nblowers, and energy recovery units.<\/p>\n

Motor Energy Upgrades<\/strong>
\nMegan Leick, spokesperson for Aprilaire, said increased standards have resulted in improved motor
\nefficiency in recent years.<\/p>\n

\u201cASHRAE 62.2 is changing, and in some states, the IECC [International Energy Conservation Code]
\nenergy efficiency, 2.8 cfm per watt, is becoming code,\u201d Leick said. \u201cIn those states, the blower motor
\nmust meet that efficiency. Now, there is a choice to use an ECM with the HVAC furnace and small air
\nhandlers fans, making them more energy efficient.\u201d<\/p>\n

\u201cLow-cost, poorly performing fans are being coded out nationally,\u201d agreed Ken Nelson, Northwest
\nregional sales manager at Panasonic Eco Solutions North America. \u201cThe fan market, as a whole, is getting
\nmore efficient and quiet. This rising tide even has Panasonic raising its bar of efficiency. We continue to
\nredefine what WhisperQuiet means \u2014 Panasonic fans are truly whisper quiet.\u201d<\/p>\n

Jalena Pfister, spokesperson for Continental Fan Mfg. Inc., agreed that lower-cost, noisy fans are going
\naway. \u201cThey have become more efficient and quieter,\u201d she said. \u201cHVI [Home Ventilating Institute] and
\nEnergy Star requirements have driven this, and ASHRAE 62.2 is driving more efficient fans and controls
\nto meet the requirement.\u201d<\/p>\n

Matt Menard, market manager, air conditioning, ebm-papst Inc., said the company has a simple
\nphilosophy: \u201cEvery new product designed must be economically and ecologically superior to its
\npredecessor. \u201cWe strive to make our products more efficient while reducing the acoustics in every new
\ngeneration of product,\u201d he said. \u201cAt the heart of our ecologically friendly products is our award-winning
\nelectronically commutated (EC) technology integrated into the electric motors. ECMs and fans can be
\neasily controlled, are maintenance-free, offer outstanding efficiency, and have a considerably long service
\nlife.\u201d<\/p>\n

Pat Nielsen, marketing manager, balanced ventilation system, Broan-NuTone LLC, said fans are also
\nbecoming easier to install.<\/p>\n

\u201cWe are focused on helping our contractor customers save time and money,\u201d he said. \u201cThe new
\nULTRA\u2122 Pro fan, for example, can be installed in minutes with no attic access because of its unique
\ntelescoping mounting frame, which can collapse together to fit through drywall openings and then expand
\nonce above the ceiling.\u201d<\/p>\n

Whole-Home Ventilation<\/strong>
\nAnother trend Erbe noted is the move toward whole-home ventilation, especially in new homes or homes
\nthat have been sealed. He added that energy recovery is becoming a bigger part of ventilation on the
\nresidential side, especially in new homes.<\/p>\n

\u201cWhen you have whole-house ventilation in a tight environment, you need energy recovery,\u201d he said.
\n\u201cYou need to bring in the outside air to lower the level of all the pollutants simultaneously, then you need
\nto be able to use that airstream to transfer the energy, then let it exhaust out. Just the idea of bringing
\nsomething in, treating it, and throwing it back out \u2014 that\u2019s going to use energy, not save energy.\u201d
\nJay T. Ayers, geothermal and IAQ product manager, HVAC residential North America, Ingersoll Rand,
\nagreed that \u201csome form of controlled ventilation will be required in all residential construction when the
\nstandard is adopted into state and local building codes.\u201d He added that the FreshEffects\u2122 air filtration
\nsystem from Trane, a brand of Ingersoll Rand, accomplishes that task.<\/p>\n

\u201cA system like this exchanges a small amount of indoor air with outdoor air and recovers about 80
\npercent of the sensible heat transfer and mitigates latent heat transfer at the same time,\u201d Ayers said.
\n\u201cFreshEffects will meet the requirements of 62.2-2013 and only uses the energy equivalent of a couple of
\n100-watt light bulbs.\u201d<\/p>\n

Similarly, Aprilaire offers the Home Comfort Control\u2122 (8620 and 8910), which provides \u201can
\nunprecedented opportunity to actively manage ventilation, as well as every other aspect of indoor air
\nquality throughout your home,\u201d Leick said. \u201cThat includes air purity, humidity, and temperature \u2014 all
\nfrom one simple and easy-to-operate control.\u201d<\/p>\n

What\u2019s Next?<\/strong>
\nCarl Redner, president of General Filters Inc., said every home \u2014 especially new homes \u2014 needs
\nventilation or air treatment equipment to remove odors, correct humidity, and address indoor pollution as
\nwell as stale air.<\/p>\n

\u201cTo keep windows open in these times is not reasonable due to weather conditions, safety concerns, and
\nnoise,\u201d he said. \u201cToday\u2019s homes are being built tighter and have greatly reduced, if not eliminated, the
\nnatural exchange of inside air.\u201d<\/p>\n

Nielsen said tighter envelope construction has made ventilation and IAQ a higher priority than ever
\nbefore. \u201cThe International Residential Code (IRC) and International Mechanical Code (IMC) have
\naddressed the impact of airtight constructions on indoor air quality by adding make-up air regulations for
\nlarger-volume kitchen range hoods,\u201d he said. Nelson predicted \u201cwe\u2019ll be seeing more balanced ventilation<\/p>\n","protected":false},"excerpt":{"rendered":"
