Clean HVAC System/Coils Saves $40,000 Annual in Energy Costs While Improving IAQ
Study Verifies Coil Cleaning Saves Energy revealed a $40,000 a year savings from just one air handling system as a result of the restoration of the air handler/coil system at the 1500 Broadway a 34 story skyscraper building in Times Square, New York City home to ABC Studios and Good Morning America.
One of the most overlooked steps in the final stages of construction, a renovation project or HVAC system change out is a thorough, professional cleaning of air conditioning, heating, and ventilation (HVAC) systems.
The National Air Duct Cleaners Association (NADCA) states an HVAC air duct system should normally be inspected every year and cleaned when it is visibly dirty, which is about every three to five years, depending on maintenance.
According to the US Department of Energy (DOE) the “HVAC system accounts for 40 to 60 percent of the energy used in U.S. commercial and residential buildings. This represents an opportunity for energy savings using proven technologies and design concepts”.
A recent article in the ASHRAE Journal authored by Ross Montgomery, PE entitled Study Verifies Coil Cleaning Saves Energy revealed a $40,000 a year savings from just one air handling system as a result of the restoration of the air handler/coil system at the 1500 Broadway a 34 story skyscraper building in Times Square, New York City home to ABC Studios and Good Morning America. In addition, the study indicated that they were able to decrease coil pressure drop 14% resulting in a corresponding increase in air flow and increasing the thermal efficiency of the cooling coil 25% while improving IAQ conditions.
Construction projects often create a lot of dust and debris, which can be pulled into the HVAC system, where it will contaminate the inside surfaces of the duct.
As a result of this, many environmental consultants, engineers and architects have requested that the newly installed ductwork be cleaned to ensure good indoor air quality (IAQ) in the building once the HVAC system is turned on in order to achieve US Green Building Council LEED Gold certification program.
Cy Garner, Account Mananger for Building Remediation Sciences (division of Pure Air Control Services) states that “many of our valued clients are requesting that we assist them in professionally cleaning the HVAC system and provide a QA/QC program to achieve their LEED Gold rating. They are getting points toward their LEED Gold label by this effort and it’s a great way to achieve a high energy status, an energy savings as much as 15% and improve IAQ helping create a significant economic stimulus.”
Additionally, it is a good idea to inspect the air ducts before you start remodeling, reconstruction or installing a new air handling system. Chances are that the air duct systems have not been cleaned since they were built or if they were they most likely were not done professionally. Many times original construction debris, such as sheetrock, molding or ceiling and wall texture overspray, is still in the duct 20 years later. Environmental constituents such as mold, bacteria, mycotoxins and endotoxins exist in the air ducts a result of neglect often spewing spores into the occupied spaces. The amount of debris removed from HVAC system can be astonishing, oftentimes 10’s of pounds of debris removed most of which is allergy causing to building occupants.
HVAC systems have a significant effect on the health, comfort, and productivity of occupants. Issues like user discomfort, improper ventilation, and poor indoor air quality are linked to HVAC system design and operation and can be improved by professional environmental cleaning.
Industry performance standards developed by the National Air Duct Cleaners Association require that all interior surfaces of an air duct system be thoroughly cleaned, from the point air enters the system downstream to where it exits at the supply registers, including the air handler, evaporator coil to the return air registers.
During the cleaning process the HVAC system must be placed under HEPA fitted negative air pressure, to control dust. Power brushes and compressed air are utilized to loosen debris being pulled downstream to the high powered 5000 cfm vacuum where it is removed from the system. In Florida, a contractor must have an air conditioning and refrigeration contractor licensed to clean air duct systems to association standards or to obtain certification as an association air system cleaning specialist.
Charlotte County School District has implemented a "Green Cleaning" program to not only save energy but also to improve indoor air quality and mitigate long-term health risks and allergies associated with indoor air pollutants. This program introduces a chemical free coil cleaning process called PURE-Steam Coil Cleaning a safe and effective cleaning process used to save energy and create a healthy learning environment for students, school staff and visitors.
As a part of this initiative, the Charlotte County School District has contracted with Pure Air Control Services a national leading indoor environmental contractor with over 25 years of building IAQ experience. Because the PURE-Steam Coil Cleaning program is totally GREEN (NO CHEMICALS) students, school staff and visitors don’t have to worry about potential dangerous chemicals or Volatile Organic Compounds (VOC) entering into the air or water system.
Don Terry, Manager of HVAC Maintenance noted that “not only are we saving energy, but we are creating a healthy learning environment for our students and faculty.
The U.S. Environmental Protection Agency (EPA) has long been a proponent of improving indoor air quality in the nation’s schools stating on their web site that “Poor indoor air quality (IAQ) can cause illness requiring absence from school, and can cause acute health symptoms that decrease performance while at school. In addition, recent data suggest that poor IAQ can reduce a person’s ability to perform specific mental tasks requiring concentration, calculation, or memory.” Indoor air quality (IAQ) is a critically important aspect of creating and maintaining quality school facilities.
Additionally, Mr. Terry stated that “your staff, crew and support team are great to work with. I would highly recommend your Pure-Steam Coil cleaning process to any facility/HVAC manager interested in saving energy, improving indoor air quality and creating a healthy school.”
