air levels can often be reduced to between 7.5 and 10 CFM per person. For example, a school with a 60ton rooftop unit can expect annual savings on utility costs in the range of $3,000 to $12,000 depending on the geographic location of the building, the utility rates and the hours of operation. Capital Investment. Reduced outside air can favorably impact equipment selection. Lower fan horsepower requirements can translate into smaller tonnage equipment. Maintenance. Polarized-media electronic air cleaner media pads last longer than conventional passive filtration, extending changeout intervals and saving labor costs. Maintenance personnel like the light-weight pads that are lighter, less bulky than equivalent efficiency bag or cartridge filters, and easier to store and handle.
But Wait, There’s More! High efficiency air cleaning systems offer other benefits for schools, as well: Improved IAQ. High efficiency air cleaners remove dangerous airborne particles that other air cleaning systems miss — including odors, VOCs, smoke, bacteria, allergens, fine dust, molds and pollen — without producing any harmful ozone. Mold Prevention. Air cleaners that collect mold spores reduce the risk of potential mold problems by removing mold spores from the air stream, as well as sub-micron particles, which can provide a food source for mold growth. Versatility. Few air cleaners offer the same versatility when it comes to application in the types of HVAC equipment used most frequently in schools. Versatile air cleaners can be applied to packaged terminal units, unit ventilators, rooftop units,
water-source heat pumps, as well as large custom air handling units. Increased Attendance. Studies document the correlation in the reduction of student and staff absenteeism to cleaner air in schools. Poorly controlled asthma can more than double healthcare costs and threaten educational achievement. Cleaner Air Means Happier, Healthier Students Dynamic’s Watcke sums it up this way: “It’s important to remove barriers to learning in our schools and to offer a safe and healthy environment for our children. It’s good to know that you can do so, and that it can be done at zero net cost.” For more information about IAQ and options for schools, visit www. dynamicaqs.com/commercial.
Air Filtration:
Your next Energy Conservation Measure? The Dynamic V8 Air Cleaning System offers sustainable MERV15 performance for better IAQ, using 2/3 less fan energy than MERV14 filters and removing odors, VOCs and ultrafine particles without Ozone. The Dynamic V8 also offers average maintenance intervals exceeding four (4) years. The Dynamic V8 can cut fan energy costs in half. And additional substantial savings may be available through reduction of ventilation air requirements using the IAQ
AIR CLEANING SYSTEM
Procedure in ASHRAE Standard 62. The IAQ Procedure allows recirculated indoor air to be cleaned rather than supplemented with outdoor air that requires heating or cooling. Schools can achieve higher rates of air filtration with much lower pressure drop, allowing HVAC systems to operate at lower brake horsepower than comparable conventional air filtration systems.
