Unitized Multi-Family Ventilation

IAQ, Bath & Kitchen Fans

Innovation in Ventilation

Improving the Quality of Indoor Environments

unitized multifamily venting venting each dwelling independently
“Unitized” Multifamily Venting(Venting each dwelling independently)
  • Common in Low-Rise Apartments and High-rise Condominiums
  • Primarily intermittent bath and kitchen fans
  • Usually does not address IAQ
challenges of unitized venting multi family buildings
Challenges of Unitized Venting Multi-family Buildings
  • Fan Locations and Ducting
  • Venting Penetrations
  • “Traditional” Fan Performance
  • Airflow Control and Occupant Operation
  • Maintenance
challenges of unitized venting multi family buildings4
Challenges of Unitized Venting Multi-family Buildings
  • Locating individual fans and vent ducts always presents a challenge.
  • Multiple Penetrations can be costly and unsightly.

Challenges of Unitized Venting Multi-family Buildings

Lengthy duct runs make

installation difficult, and

dramatically affect airflow

performance.

building codes
–Building Codes
  • Most residential building codes for ventilation are based on ASHRAE standard 62.1 for high rise buildings (over 3 floors) and 62.2 for low rise buildings.

Traditional Bath Fans –Performance Limitations
  • Low airflows in most installations\

Traditional Bath Fans –Low Airflow Performance
  • Pressure Drop from Duct Terminations and Elbows…

Traditional Bath Fans –Low Airflow Performance
  • Typical Pressure Drop Example: 50 cfm fan, 25 ft. smooth 3” vent duct, two 90 deg. Elbows, & wall cap.
    • Duct = .193” Ps
    • Wall cap = .095” Ps
    • Elbows (Total) = .156” PS
    • TOTAL PRESSURE DROP = .444” Ps
  • What actual airflow delivery can you expect?
traditional bath fans noise prevents proper use
Traditional Bath Fans –Noise Prevents Proper Use
  • HVI independent studies have determined that, “…anything above 1.5 sones for intermittent, and 1.0 sone for continuous operating fans is considered objectionable to people.”
  • Over 90% of the fans sold in 2001 delivered 4.0 to 6.5 sones… 3 TO 4 TIMES TOO LOUD!!!
traditional bath fans maintenance issues
Traditional Bath Fans –Maintenance Issues
  • What about maintenance?
  • Cleaning and replacement?

The American ALDES Solution
  • How To Address the Challenges of:
  • Airflow through long duct runs
  • Noise
  • Occupant Operation
  • Minimize outside penetrations
  • Maintenance

The American ALDES Solution
  • VentZone
  • System
  • Bath,Kitchen and/or IAQ systems
  • Single ENERGY STAR rated fan
  • Zone controlled
  • Self balancing
  • Pressure independent
  • Continuous duty rated

NOISE

The American ALDES Solution
  • Remote installation ensures quiet operation and proper occupant use.
  • In most installations, the sound levels in the space are between 0 and .75 sones.
