Special Circumstances

• Ventilation air provided by a dedicated outdoor air system (DOAS) comprised of packaged DX rooftop units and VAV terminal units.  Pre-condition 100% outside air is supplied to zones for precise control based on occupancy and maximum energy savings. 

• Sound ordinances and small site footprint resulted in placement of the cooling tower on the classroom building roof.  Cooling tower equipped with special acoustical fan blade for low noise operation.

• Project was fast-track design-build contract with 9 month construction window.

• HVAC design included sound dampening strategies to comply with LEED prerequisite for a maximum background noise level of 45 dBA.
