The multi-billion-dollar Arzanah Medical Center in Abu Dhabi was nearing completion and was ready to be the latest shining example of the United Arab Emirates’ architectural leadership. So it was with deep concern that engineers reviewed traverse readings taken from several of the structure’s HVAC risers that indicated leaks were robbing the facilities of half of the air traveling through the ductwork. Not only was this unacceptable from a building code perspective, but it also created significant concerns regarding indoor air quality, building performance, and energy costs.
BUILDING
Arzanah Medical Complex
AEROSEAL CONTRACTORS
Trent Technical Services
CONTRACT ENGINEER
Habtoor Leighton Group
GOAL
Meet 8% leakage specifications
BEFORE AEROSEAL
Up to 50% or more of leakage
AFTER AEROSEAL
5% or less leakage
RESULTS
Eliminated duct leakage in a 127,000 CFM system including all HVAC, exhaust and smoke extract systems
An Internet search for a better solution led the engineering team to Aeroseal – a duct sealing technology that works from the inside to seal leaks. After the technology passed rigorous safety criteria, an Aeroseal team was brought in from the U.S. to demonstrate the technology on several leaking risers. Test results were so impressive that the building engineers decided to use Aeroseal throughout the complex, including the HVAC exhaust, the HVAC supply, the HVAC return, the lab exhaust, the kitchen exhaust, and the structure’s entire smoke extract system – a 127,000 CFM system in all. Work was completed in two weeks.
