Every building needs fresh air.

But what most owners don’t realize is how much of that air never actually makes it where it’s supposed to go.

In multi-residential buildings, Make-Up Air systems are responsible for delivering fresh air and maintaining corridor pressurization. Yet due to duct leakage, a significant portion of that air is lost before it ever reaches its destination.

The result:
* Higher natural gas and electricity costs
* Overworked equipment
* Inconsistent comfort and air quality

In some cases, these systems account for up to 30% of a building’s natural gas usage.

We recently put together a short video that breaks down the problem, and more importantly, how to solve it without invasive construction.

NERVA’s Make-Up Air Optimization Program uses a proven, non-invasive approach to seal ductwork from the inside, reduce energy waste, and improve overall system performance.

It’s one of the most impactful, yet overlooked, opportunities in multi-residential portfolios.
