Ducts leak… It’s not a secret

Top energy inefficiencies
But it is a problem…a significant one! ASHRAE estimates that 75% of commercial buildings have 10-25% duct leakage. A recently conducted survey by BCA confirms it:

  • 75% of respondents believe leaky ducts contribute substantially to energy loss in commercial buildings.
  • 73% believe most U.S. buildings today have significant duct leakage.
  • 46% have found significant duct leakage most prevalent in existing buildings.

The cost in lost energy from these duct leaks is HUGE. A commissioning study from Berkeley National Labs shows duct leakage to be the TOP building fault when it comes to energy waste. In fact, annual energy cost from duct leakage is estimated to be a whopping $2.9 billion. Nearly double its closest “rival” – leaving the HVAC on when building is unoccupied.

So why is this problem still so rampant? Duct leakage in commercial buildings has been all but ignored for one simple reason – there was no viable solution to fix the problem, until now. Aeroseal duct sealing technology seals ducts from the inside to reduce leakage by up to 90%, thereby lowering fan speeds and saving precious energy. This method is high effective, affordable and simple when compared to tape or mastic, and has none of the access limitations.

Abstract & Learning Objectives

In this webinar, panelists will give an overview of the problem, and introduce attendees to specific tools to estimate duct leakage and methods used to ensure a building is a good candidate for duct sealing. Project results will verify the efficacy of the duct leakage estimating tools.

Learning objectives include:

  • Learn to understand the potential energy loss attributable to duct leakage in commercial buildings.

  • Learn how to calculate and quantify energy loss due to duct leakage.

  • Learn and to document and present the elimination of duct leakage as an energy conservation measure (ECM).

  • Learn about the remedies for duct leakage and how they are implemented.

Special guest panelist, Rob Lester from Ameresco will walk through a real-life project example to demonstrate the how energy savings was achieved, using the Aeroseal measurement and verification tools. Lester will also highlight why and how Ameresco uses the duct sealing ECM with its ESCO customers.
