Multi-Story Building Exhaust

Appliances in multi-story, multi-family and mixed-use buildings often have long exhaust ducts serving multiple kitchens, bathrooms or dryers that produce particles or odors. These appliances typically operate less than 30% of the day. Yet, most multi-story building exhaust systems run at full speed 24/7. Why waste your energy (no pun intended)?

A demand-controlled ventilation system can convert multi-story building exhaust into energy savings of 85% - which could amount to $500 per dryer or kitchen and $200 per bathroom.

ENERVEX offers a wide range of energy-saving, aesthetically pleasing, flexible and quiet solutions for spot exhaust in virtually every type of new or retrofit application - from sports arenas, hotels and resorts to multi-story vertical subdivisions, schools and colleges.

These building exhaust solutions adjust automatically to the energy output demands of your application. If no appliances are running, the system operates at a very low speed. Once an appliance starts, the fan kicks up pressure inside the duct. The system senses that pressure and begins increasing ventilation speed.

ENERVEX has seen demand-controlled ventilation systems helped customers achieve:

  • Up to 90% reduction in fan energy consumption
  • Up to 80% reduction in the cost of conditioned air being exhausted
  • Savings up to $10,000 per duct riser (with just one sq. ft. per floor in a 20-story building)
  • +/-2% accuracy from set point vs. +/-20% accuracy in alternative solutions

ENERVEX is behind some of the world’s highest-profile buildings including: Burj Khalifa Tower (Dubai), Americana-at-Brand (Glendale, CA), Park Potomac Place (Potomac, MD) and The Platinum (New York, NY).
