Indoor air quality (IAQ) is greatly affected by the level of ventilation in a home or building. Today's more air-tight buildings may not be ventilated properly to eliminate contaminant buildup, such as dust, chemicals, humidity and other allergens. Heat Recovery Ventilation (HRV) and Energy Recovery Ventilation (ERV) systems rejuvenate air by exchanging stale indoor air with fresh, clean air as much as eight times a day. With the state-of-the art heat exchange process, the system improves HVAC efficiency by transferring the temperature of the outgoing air to the incoming air, which creates a more comfortable, evenly heated and cooled environment.
The American Society of Heating, Refrigeration, and Air Conditioning Engineers' (ASHRA'), latest standard for residential homes (ASHRAE 62.2) recommends a minimum of 7.5 cubic feet for each person and 1 cubic foot for each square foot of living space in outdoor make-up air per minute (CFM), be brought into indoor living areas.IECC 2009 and IECC 2012 building codes are now requiring new construction to be tested for adequate ventilation. Today's air-sealed and better insulated buildings need to have properly-sized HVAC and ventilation mechanicals to ensure healthy indoor air quality. A BPI or RESNET certified energy auditor can perform ventilation and air quality assessments, on new and existing homes, make recommendations and provide IECC and Energy Star verifications.
According to the EPA, the air inside of homes can be as much as 10 to 70 times more polluted than the air outside. "This is one of the reasons we have expanded our home comfort services. We don't want to see homeowners invest time and money in efficiency improvements only to develop air quality issues," says Robert Schildgen, owner and CEO of Priority Energy. 'Lifebreath clean air products offer safety benefits as well. Since they operate off of the hot water system there are never concerns about flames, fumes or flue gases."
As the leading energy solutions and ventilation experts in Chicago, Priority Energy consultants say there are several steps to designing a ventilation system that will maximize indoor air quality in a new or existing home. A building's overall air tightness level will determine its need for ventilation and the type of system that is best suited for a specific home or building. A trained auditor will address existing problems with the building structure (mold, asbestos, etc.), existing occupant health concerns (asthma, allergies, etc...), and of course advise on efficiency and comfort targets; all factors in the proper design of a customized ventilation system.
Priority Energy will host a training seminar for Contractors, Building Officials, Architects and Energy Auditors titled:
