Duct Sealing Key to $37,000 Annual Energy Savings for N.J. High Rise
CENTERVILLE, Ohio — A 23-story high rise apartment building in Camden, N.J., has reduced its utility bill $37,000 a year by replacing dampers and sealing leaks in the building’s exhaust duct system with Aeroseal, a duct sealing solution provided by Aeroseal LLC. By sealing the leaks, Aeroseal helped reduce by more than 217,000 kWh the amount of energy required by the building’s two exhaust fans. This results in an annual cost savings of about $34,000. An additional energy savings of an estimated $3,000 a year was accomplished through increased heating efficiencies resulting from the duct sealing process.
The Northgate II high-rise apartment building began undergoing energy efficiency upgrades with funding from New Jersey State’s Multifamily Weatherization Assistance Program (WAP). To qualify for this funding, an energy audit of the entire 308-unit apartment building was performed and a course of action was determined. Among the various requirements outlined in the final project plan, the independent auditors specifically specified the use of the Aeroseal technology to effectively seal the duct leaks that existed throughout the building’s exhaust duct system.
