SoundShield: Noise Attenuation for e-Designation

High Efficiency PTAC w/ SoundShield

For buildings located in high-traffic, noisy areas, it’s critical to be able to dampen the din of noise pollution. To meet this demand, Ice Air has created a new product that lessens the effects of sound coming through Packaged Terminal Air Conditioners. known as SoundShield™.

This new PTAC feature helps buildings pass stringent environmental codes, including New York City’s Office of Environmental Remediation (OER)’s “small e” designation code.

Recently, the OER has taken a stronger approach to sound attenuation for new buildings. In an effort to minimize outside noise transfer caused by highway, subway, train or airport noise, they have implemented the Outdoor-Indoor Transmission Class (OITC) and Sound Transmission Class (STC) ratings, which apply to building components that affect the building’s envelope.

SoundShield: Noise Attenuation

When Ice Air bid on the Richmond Place project, located in the Richmond Hill neighborhood of Queens, NY, we knew that it wasn’t just a typical Packaged Terminal Air Conditioner (PTAC) job. The mixed residential complex contains 117 apartments for market-rate, low-income and supportive housing, and required 444 high efficiency PTACs. The one hurdle was that the building’s location was zoned as “e-designation,” meaning that the PTACs would need to meet a minimum sound transfer requirement.

Although PTACs typically allow some sound transfer through their window/wall openings, there was no product on the market to mitigate it. Ice Air worked with  the project’s Mechanical Engineer, Peter Joselow of Abraham Joselow, PC, to develop a PTAC unit that would dampen sound transfer from the outside, creating a quieter room inside.

SoundShield underwent extensive in-house and third-party testing, garnering impressive OITC and STC ratings. As a result, it was clear that SoundShield provides a marked improvement for an indoor environment when there is excessive outside noise. The PTACs with SoundShield has been certified with the NYC Noise E-Designation Remedial Action Plan. Now, thanks to Ice Air’s innovative approach to advanced HVAC equipment, the residents of Richmond Place can enjoy peace and quiet inside their homes.
