Post Construction Testing Found Building’s ERV System Did Not Meet Specifications – Aeroseal Proved To Be The Ideal Technology To Fix The Problem
After only a few months of being open, the new Veterans House at the VA medical centre in Indianapolis realized their Energy Recovery Ventilation (ERV) system wasn’t working properly. The problem was the intake and exhaust vents throughout the facility and through the ERV were full of leaks making it impossible to balance and adjust the airflow. Strict government standards require there to be less than 10 per cent of leakage. Testing showed that the system had a leakage rate of 45 per cent in some place. Faced with a big problem, the heads of the medical centre were preparing to close down the facility and start tearing down walls and ceilings in order to access all the duct work and seal the leaks. Luckily the construction company did a quick internet search and found Aeroseal.
In Brief
Building: Veterans Administration
Engineer: RL Turner Corporation
Duct Specialists: Reupert Heating and Air
Goal: Meet ERV specifications
Before Aeroseal: 900+ CFM* of total leakage
After Aeroseal: 63 CFM of total leakage
Results: Reduced leakage by 93 per cent
*cubic feet per minute
It took the duct company only three days to seal the building’s whole ductwork – the other option, tearing down the ceilings and walls, would have taken over a year to complete and hundreds of thousands of dollars of wasted money. Aeroseal works from within the ducts and seals the holes leaking air so finding and fixing the leaks doesn’t require you to destroy all the completed work. The work is safe, efficient and highly effective. The work was finished over Memorial Day weekend and the facility was finished to celebrate with the family of the people who lived there.
Realizing how effective the technology was, the administrators decided to use Aeroseal on all four of their ventilation systems on the campus.
Quotes
“Aeroseal proved to be the right solution for the problem. I’ve been in this business for quite a long time and I’ve seen quicky solutions come and go, but this one actually held water…or I should say ‘air’ as the case may be.”
Timothy Flynn, General Engineer, Roudebush VA Medical Center
“I did my research and found that short of tearing down and starting over, there was only one option – Aeroseal. For retrofits and new construction projects like this, it is the ideal solution. The technology prevented a much more expensive and invasive procedure.”
David Petty, RL Turner Corporation
“The before and after reports showed us the results. The VA’s independent contractors then came in and confirmed what we already knew – Aeroseal did the job. And while we were simply looking to reduce leakage and fulfill specification requirements, it doesn’t take a rocket scientist to add up the difference Aeroseal made in system performance and know that it also provided a significant savings for somebody’s checkbook.”
