Reducing the leakage at Filip Vtori Cardiology Unit, Macedonia

The air duct systems installed in the recently constructed cardiosurgery facility named "Filip Vtori" exhibited significant leakage issues. These problems were attributable to the suboptimal quality of the air ducts and their installations. As a result, certain rooms within the building did not receive adequate airflow, which could potentially compromise hygiene and increase the risk of health problems caused by uncontrolled airflows.

The malfunctioning ventilation system posed significant challenges for the timely completion of the project. The building's opening was postponed, and the client had to prolong their stay in the old facility, which resulted in high rental costs.

PROJECT

Building: Cardiosurgery Filip Vtori
City: Skopje, Macedonia
Date: 09. - 19.11.2015

Target: Compensate shortcomings of the ventilation system and ensure the building's opening in a timely manner
Preseal leakage: Air tightness class A and worse
Postseal leakage: Air tightness class D and better
Reduction of leakage: in between 93 and 98%

Project overview

The entire ventilation system of the building was sealed. The systems mainly consisted of rectangular sheet metal ducts with flanged connections. Due to the size of the building, ducts run of up to 120 meters length were sealed per sealing event. More than 500 openings had to be closed before this job (and of course re-opened afterwards). Thanks to MEZ-AEROSEAL, the delay of the building's opening could be minimized and the ventilation system now works without any limitations.

Customer Testimonial:

"Our hospital is equipped with the newest high efficiency HVAC systems also using renewable energy sources. So we cannot afford losing this efficiency through leaky air ducts. Thanks to MEZ-AEROSEAL we have now solved all hygienic, energetic and performance related problems at once. Furthermore, an additional delay of the building's opening could be avoided"
