Priority Energy, Aeroseal for Commercial Buildings, IL

Lower utility costs & improve HVAC performance!

Aeroseal is solving a large range of problems found in commercial buildings all across the country. It is also making it quicker and easier for buildings to meet the stricter IECC building and energy codes, ASHRAE requirements, and LEED certification. Whether it’s improving energy efficiency and indoor air quality or controlling humidity and balancing air flow, Aeroseal duct sealing can help.

Meet HVAC System Performance Standards

Retro-commissioning professionals have listed “excessive duct leakage” as the main reason why commercial buildings are struggling to meet HVAC performance standards, according to a recent survey of building commissioning engineers. Sealing the duct system with the Aeroseal process is the only cost-effective, guaranteed solution for these complex buildings.

Aeroseal has been proven to be less expensive than traditional tape and mastic, largely because it so significantly reduces the number of man-hours it would take to properly seal and test these large systems. It also eliminates guesswork and the need to re-test. The computerized system measures the leakage rate as the sealing is in progress and creates a certificate with a graph of before and after results which can be immediately given to an inspector.

Both existing and new buildings can benefit from Aeroseal’s non-invasive, sealing-from-the-inside method of duct sealing, which is guaranteed to pass IECC code requirements. Priority Energy has an experienced and award-winning team of Aeroseal pros who have sealed hundreds of leaky duct systems. They are trustworthy, arrive on time and get it done right.

Aeroseal Can Help with Building Commissioning Requirements:

Lower Energy Consumption

High duct leakage can cause the exhaust fan to run overtime, which will significantly increase heating and cooling costs. Air leaks in an exhaust system can increase fan use by as much as 95% (ASHRAE). Additionally, excess airflow due to leakage often creates uncontrolled air infiltration through the building envelope or excess outside air intake through the HVAC system, further impairing energy efficiency and building comfort.

Healthier Indoor Air Quality and Safety

Leaky ductwork can spread mold and other contagions throughout a building, creating what we call “sick building syndrome.” Poor ventilation, insufficient air changes (ACH) and pressurization problems, which all cause sick building syndrome, have been linked to duct leakage.

In tall buildings, seasonal stack effect can increase ventilation problems from toilet and kitchen exhaust systems not properly sealed. Self-regulating exhaust dampers can also lead to excessive energy consumption and poor indoor air quality through leaking exhaust shafts.

More Even Air Flow

Evenly distributed air flow to all the floors and rooms in a building will significantly improve the overall performance of the HVAC system(s). It is important that both the supply diffusers and return grilles are properly balanced. Aeroseal is able to seal leaks in otherwise inaccessible duct systems in both new and existing buildings, which will enhance airflow.

Priority Energy also provides testing and balancing service and reports for IECC compliance verification.

Increased Heating and Cooling Capacity

If your cooling or heating is not meeting your needs, possibly due to higher occupancy, duct sealing may be able to meet the increased needs simply by improving airflow and HVAC performance. Consider an Aeroseal consultation before replacing your commercial heating and cooling equipment.

When ducts are leaking nearly 20% of the air they are supposed to deliver to each zone, sealing the leaks should become a priority. Aeroseal can significantly increase the system’s cooling capacity to meet the increased cooling loads. On average, the process seals 80-90% of the leakage encountered.

Certified Low VOC Compliant with LEED V4

DUCTSEAL, the aerosol sealant used during the Aeroseal duct sealing process, has been certified compliant for low volatile organic chemical (VOC) emissions in accordance with the latest LEED standards set by the U.S. Green Building Council. Third-party testing by Berkeley Analytical concluded that the sealant tested below the lowest VOC concentration range of £0.5 mg/m3 for the presence of formaldehyde and other targeted VOCs.

  • Thank you again and you will be the first person I call if I need additional part or service from your company.
  • I just wanted to send this message to all you and say GREAT JOB!  We had a rough inspection today and passed for the Woodward Ave. house. The inspector told us "if every house I inspected looked like this one I would be out a job".

  • We were so impressed with the amount of information the Priority Energy technicians gave us during our ENERGY AUDIT.  If you are buying a house, I would strongly recommend having them do an energy audit on it, in addition to your usual home inspection.

  • Thanks for a super intelligent and deep seminar expertly handled by a staff which was a pleasure to be around. Lunch was superbly and subtly handled.

  • I wanted to thank you for all of your extra time and energy during our BPI training over the last few weeks. You really helped put things in perspective. You are an awesome crew and your facility is a valuable resource for students and the community

    BPI Student, L.E.
  • There is much less dust in the house and the monthly gas and electric charges have been reduced by 10 to 15%.....I'm sure I will see greater savings over a twelve month period......thanks again.

    Aeroseal Client, R.N.
  • Just completed my BPI Field exam for my Quality Control Inspector (QCI) certification renewal at Priority Energy.
    Such a convenient and well-set-up training and test center with caring and knowledgeable staff and proctors! Thanks folks!

  • It's been cold here for the past few days and I really feel the difference in heating since the building was Aerosealed! My apartment is so much warmer now. Thank you Priority Energy!

  • Anytime I can be a reference for all the great work on my (new) house, please let me know.  Priority Energy is outstanding at what they do!

    Executive at Medline Industries, IL
  • I have a two story home built in the mid seventies. Lots of temperature fluctuation between the floors. The Aeroseal process dramatically increased the air flow to the second floor. Good experience. The company was very informative, answered a lot of questions.
