Is Air Filtration the Next Light Bulb? Over 90% of the cost of filtration is Energy

| December 2, 2015

It’s no secret that the lowest hanging fruit for energy-saving initiatives has been lighting. Hundreds of millions of tons of CO2 emissions have been saved. In fact, at this point, we see high-efficiency lighting designed into most new construction projects. Many of the larger retrofit projects have been done, as well. This leaves designers and owners looking for other places to find savings. Fortunately, air filtration and indoor air quality both offer huge opportunities for energy efficiency. As with lighting, these are areas where designers often default to methods they used in the past.

Today building occupants expect their indoor air to be free of contaminants. This has led to higher efficiency filters and in some cases more outdoor air for ventilation. Until recently, both of these approaches would normally increase costs. The biggest cost is not in the cost of the filter itself, but rather in the cost of the energy to push air through it. Energy represents over 90% of the cost of air filtration. With conventional passive filters, increasing filter efficiency means increasing the static resistance to airflow, which increases the energy use.

Today there are Ozone-free air cleaning technologies, like the Dynamic V8 Air Cleaning System from Dynamic Air Quality Solutions that operate with a much lower static pressure resistance than conventional high-efficiency filters. They are capable of removing odors and VOCs in addition to ultrafine particles. And because they enjoy a much greater dust-holding capacity than passive filters, maintenance intervals are measured in YEARS instead of months. These factors give the Dynamic V8 about 1/3 of the life cycle cost (including energy) of conventional passive filters, while improving overall air quality.

In some cases where appropriate, even more savings can be achieved. Air cleaning can help implement the IAQ Procedure of ASHRAE Standard 62 to yield improved air quality and lower energy costs by reducing outdoor air levels and the energy required to heat and cool outdoor air.

And today it makes sense to clean outdoor ventilation air. Bans on smoking indoors and the use of low VOC-emitting building materials have improved indoor air quality significantly. Today, according to the EPA, the air outside contains more contaminants than the air indoors in most metropolitan areas.

Consider air filtration as your next Energy Conservation Measure. In total, it represents a lot of energy. Commercial buildings consume 40% of all energy in the United States. Over half of that is used to condition and clean the air. And over half of that is fan energy. Clearly, that’s some low hanging fruit.
