Energy Auditors Specify The Use Of Aeroseal To Increase Energy Efficiency And Reduce Duct Leakage by Up to 95%
Owners of Northgate II, a Section 8 community in Camden, New Jersey, were looking to reduce energy costs associated with its 308-unit apartment high-rise. To receive upgrade funding through the State’s Multifamily Weatherization Assistance Program, they had to prove that upgrades would result in substantial energy savings and a payback period of ten years or less. Energy auditors brought in to evaluate and recommend an effective course of action specified changes be made to the building’s electrical and mechanical systems.
They also insisted that Aeroseal be used to seal leaks throughout the high-rise’s entire duct system.
Property Managers: Fair Share Development
Project Contractors: McDonald Building Co.
Property Name: Northgate II
Type: Section 8, 23-story high-rise, 308 units
Goal: Reduce energy usage by 15% or more
Before Aeroseal: Average energy leakage: 971 CFM*
After Aeroseal: Average 83% reduction in CFM loss
Cost savings: $34,000/year from reduced exhaust fan usage. An additional $3,000/year from increased heating efficiency.
Payback: 3-4 years.

An initial audit of the 23-story high rise’s ductwork showed that there were thousands of leaks throughout the building’s exhaust system. As a result, the two large fans used to draw stale air out of each of the individual apartments consumed a lot of energy to do its job. By effectively sealing the leaks with Aeroseal and updating the system’s dampers, the fans’ energy use was reduced by more than 217,000 kw/hours – a savings of more than $34,000 a year in electricity. Building owners also achieved an additional $3,000 a year in savings through more effective heating.
“Preliminary testing revealed fairly large gaps throughout the building’s vertical exhaust ducts. The Aeroseal process fixed that problem and in doing so, significantly improved the efficiency of the building’s two exhaust fans. Aeroseal technology played a significant role in helping reduce energy consumption and ultimately meeting the requirements of the State’s Weatherization Assistance Program.”

“Our multi-family building specialists have a keen interest in ventilation systems and the wasted energy that often results from leaky ductwork. Through our ongoing experience with Aeroseal technology we’ve come to including the Aeroseal process as a standard recommendation when leaky duct systems are a concern.”

Aeroseal – The Technology
- Developed at Lawrence Berkeley National Laboratory in 1994.
- Research for Aeroseal was partially funded by the EPA and the U.S. Department of Energy.
- Aeroseal is the only duct sealant technology that is applied from the inside of the duct system. It is delivered as a non-toxic aerosol mist that seeks out and plugs leaks.
- Aeroseal has proven to be 95% effective at sealing air duct leaks.
Aeroseal – The Company
- Aeroseal LLC is a subsidiary of JMD Corporation. The company is dedicated solely to the support of its dealers and the expansion of Aeroseal technology as a primary means of residential and commercial energy conservation.
- Aeroseal is the sole owner and licensee of Aeroseal technology.
- Aeroseal technology was bought by Carrier Corporation in the late 1990s. In 2010, Mark Modera, the inventor of Aeroseal, with the support of private equity investors, bought the company from carrier to realize the full potential and benefits of the technology. This lead to the launch of Aeroseal LLC in 2011.
