In sustainable design and renovation of commercial buildings, the aim is to provide clearer, uncontaminated interior air for building occupants.Working toward this important objective requires a proactive stance against potential threats to occupant health.
The development of stronger strategies to prevent this problem has been caused by the importance of mold-preventive design.Adding fiberglass insulation to the ductwork of the heating, ventilating, and air conditioning system is often overlooked as a way to fight mold in the building envelope.Ductwork is an important target for mold prevention and needs the consideration of the heating, ventilating, and air conditioning professionals.
The building's heating, ventilating, and air-conditioning system is similar to the lungs of a human being, it is responsible for keeping the air fresh and clean.The air is transported through the ductwork of the heating, ventilating, and air conditioning system.It is important to keep the ductwork clean and dry.The interior air of a building can be polluted with mold and microbes from the ductwork.
Excess humidity can cause mold and microbial growth inside uninsulated sheet metal ductwork.There is condensation on the inside and outside of ducts.During the summer, as cold air travels through warm, uninsulated ducts, beads of moisture form on the interior or exterior of the ducts.In winter, heated, humidified air passes through cold ducts.When the temperature is equal to or lower than the dew point temperature, there is a high potential for condensation on duct surfaces.
Condensed water becomes an IAQ threat when it is combined with dust or dirt in un insulated ducts.If not caught in its early stages, the mold will quickly spread and cause harm to the environment.The health and comfort of building occupants can be greatly impacted by extended exposure to airborne mold spores, which can cause headaches and respiratory ailments, such as asthma.
The American Society of Heating, Refrigeration, and Air-conditioning Engineers (ASHRAE) Standard 62.1, Ventilation for Acceptable Indoor Air Quality, lists strategies for improving IAQ through mold and microbial growth prevention.The most effective solutions are to seal the ductwork and insulate it.The steps help prevent mold growth by allowing ductwork to maintain a constant temperature, which reduces the chance of condensation forming on duct surfaces.Fiber glass is the most common duct insulation material.
In addition to helping maintain a constant temperature, fiber glass is also an insulation material and does not support mold growth.It is safe and bio-soluble.More than 20 studies conducted at universities and laboratories, including the World Health Organization, have found that concentrations of fiber glass and other Synthetic Vitreous Fibers in residential and commercial buildings do not contribute to indoor air pollution.
Duct insulation can have a profound impact on improving IAQ if it is installed in conjunction with an efficient heating, ventilating, and air conditioning system.Duct insulation can be used to improve the quality of the interior environment by controlling humidity and mold.
Significant improvement to a building's interior environment can be provided by fiber glass duct insulation.It depends on how well the ductwork is maintained.
ductwork and duct insulation need to be taken care of to get the best performance.To keep the ductwork clean and in working order, it is important to schedule periodic filter changes and duct maintenance visits.Many architects and engineers are now adding preventative maintenance to their specifications due to the importance of it.
High-efficiency air filters of the correct size and quantity are important components of a well-maintained heating, ventilating, and air conditioning system.Ducts should be regularly inspected.The National Air Duct Cleaning Association has a standard for cleaning ducts.The system needs to be cleaned under continuous negative pressure.The negative air machine is used to achieve the continuous negative pressure.The use of agitation is required by the standard.The three most common methods are:
The internal drain pans should be periodically cleaned to prevent the formation of biofilms.The conditioned air should be checked for oversaturation.
Well insulated ductwork is an excellent way to improve the IAQ of a building.A purer and more comfortable interior environment is provided by high IAQ.The owners of the building will benefit from the healthier building occupants.It is a win-win situation.
