Outside Air Reduction

Outside Air Reduction

Outside Air Reduction

There is an emerging trend in the engineering field that is saving owners a great deal of money while improving the air quality of their buildings. Consulting engineers around the country are starting to utilize the IAQ Procedure from the latest ASHRAE Standard 62.1 in greater frequency. By employing the use of Plasma Air’s IAQ improvement technology, outside air intake rates can be reduced based on an analysis of contaminant levels. Therefore, air conditioning and heating systems get smaller, installation costs are reduced and ongoing energy usage is slashed. Plasma Air will provide the necessary documentation including ASHRAE's IAQ Procedure calculations and associated specifications and schedules.

Save Costs

When you can reduce the outside air intake for a school for example, reductions in both heating and cooling equipment of 20-30% would result. Per the chart below, the construction cost savings far outweigh the cost of the Plasma Air system, so no ROI analysis is required. In addition, you realize corresponding savings in installations costs, electrical service, roof penetrations, ductwork, structural support, etc. And because you are conditioning a reduced amount of outside air all year long, building owners achieve significant annual energy savings as well. Now, that's a green building!!

So whether you design using roof top units that condition the outside air directly, water source heat pumps coupled with dedicated outside air systems, or even a chilled water system with central air handling units, savings are seen across the board. Imagine the cost savings of reducing a dedicated outside air unit from, let's say, 20,000 CFM to 10,000 CFM! What if you had 2 or more of them?

And the savings are not just on new construction. They also apply when the AC equipment is replaced on existing buildings. Plasma Air can also be easily retrofitted into existing AC equipment. You won't realize the first cost savings, but the ongoing energy savings offsets the cost of the Plasma Air equipment in just a few years.

Easy Application

Buildings with high occupancy densities such as schools, churches, conference rooms, movie theatres, retail spaces, convention centers, arenas, airport terminals, hotel ballrooms, etc. are ideal candidates for this procedure. The more people in a building, the larger the outside air load becomes. The larger the outside air load, the more dramatic the savings.

Plasma Air equipment is easily installed in the supply air ductwork or in the air handler itself so no special provisions are required. The ionizers use only a few watts of power and there is no discernible pressure drop to worry about. In addition to the ASHRAE IAQ Procedure calculations, we also provide project specifications, ionization schedules, CAD drawings and our in-house engineering support by contacting us or your nearest Plasma Air distributor.

Meet Codes

ASHRAE has promoted the IAQ Procedure for some thirty years, but it wasn't until 2006 that the International Mechanical Code (IMC) included a similar provision. Employing Plasma Air's bipolar ionization system results in contaminant levels that are "equal to or lower than" those achieved using the prescriptive Ventilation Rate Method, thereby meeting code. As a result, engineers can cut outside air intake by 50% and, in many cases, by 66%.

Sustainable Design

Green Globes is a sustainable building design and management tool that fully supports ASHRAE’s IAQ Procedure.  Green Globes offers a practical, streamlined, cost effective and more flexible alternative to certify the environmental performance and sustainability of your building.  Plasma Air has participated in several Green Globe projects where reducing the outside air intake requirements significantly added to the building’s energy performance.  Engineers, building owners, and even entire cities are switching to Green Globes for their sustainable design certifications – how about you?

Proprietary Software

In buildings with high occupancy densities the predominant pollutant load is from the occupants. Typical emitted pollutants are reduced through a gas phase disassociation process lessening the requirement to dilute these pollutants through outside air intake. Plasma Air's proprietary software performs the IAQ calculations that reliably demonstrate this improved air quality and we regularly provide them to engineers around the country.

Just provide us with some basic project specific information and we'll provide you with the required calculations as the example below shows. We've completed several hundred projects to date!
