• World's first independent comparison test of lab ventilation systems under real-world stress conditions reveals groundbreaking insights 
• Results can be directly applied to design, optimization, and operation of laboratories worldwide 
• Siemens further develops its Smart Lab Ecosystem to help create labs of the future that are safer, as well as more adaptable and sustainable 

Siemens has unveiled the results of a comprehensive and independent study on laboratory ventilation in the area of life sciences. The study was conducted between November 2024 and February 2025 together with H. Lüdi + Co. AG, a supplier of core components and system solutions for modern laboratories and a Siemens Xcelerator partner. The Lucerne University of Applied Sciences and Arts (HSLU) in Lucerne, Switzerland, was contracted as the independent research and testing institution to execute all measurement activities. The project, named “PEARL”, was the world’s first to compare different lab ventilation and air distribution systems under controlled, real-world conditions. 

During the test phase, three different air supply systems were controlled and measured in seven different configurations under comparable situations and were stressed to their limits. 
The results are a unique set of data insights for each system, where specific situations can be compared, addressing various elements like safety and contamination control, user comfort, 
system flexibility, adaptability, and ventilation efficiency.
