IVAeris Oy took on a challenging task at Kauniaistentie 9 in Kauniainen, a large apartment building requiring precise airflow measurement and adjustment. KLA Talotekniikka Oy was the client for this project.
In the initial stages, challenges arose as the ductwork installation was carried out with another HVAC contractor. Some duct plugs remained in place, necessitating pressure and smoke tests. Despite these issues, IVAeris Oy’s professionals executed the job with precision and efficiency.
During the process, airflow was adjusted to avoid unnecessary restrictions. Room-specific airflow adjustments were made with room doors open and stairwell doors closed. All adjustments were meticulously performed to maintain the building’s negative pressure relative to the outside, ranging from 1-5 Pa.
Measurements were carefully documented for future replication and verification. Calibration status of measuring equipment was confirmed and recorded. Valves were locked in their adjusted positions, and the measurement log included valve IDs, adjustment positions, pressure differential, and flow rate data. A detailed record was created, listing valve IDs, type and DN size of the adjustment valve, adjustment position, measured pressure drop, adjusted flow rate, and designed flow rate.
This project underscores IVAeris Oy’s commitment to top-quality and professional execution, even when facing unexpected challenges. As a result, residents of the Kauniaistentie 9 apartment building now benefit from a more efficient ventilation system and improved indoor air quality.⬤
