• Renovated factory and book storage facility to a new school
• Pre-war, concrete laden design would make it difcult and expensive to
install air handling units.
• New York City School Construction Authority (SCA) strongly upheld a policy
for no loud air handling units in classrooms
• Couldn’t raise the oor-to-oor height for ductwork
• Large, mushroom-type columns located throughout the building limited
design exibility
• Equipment would have to meet strict acoustic specications
• The SCA and acoustic consultants required sound power levels be
kept below 72 dBA case and 56.2 dBA discharge. The Freshman units
delivered 51 dBA case and 50.7 dBA discharge.
• Virtually eliminated all case radiated sound between 1000 Hz to 8000Hz,
while also keeping discharge sound power to a minimum
• The Freshman Series of Vertical Classroom Air Handlers were selected
• Units were equipped with Changeair’s “IQ” Intelligently Quiet package
• Out performs the Indoor Environmental Quality (IEQ) acoustic requirements
section of LEED.
