What is the role of the CEN Standard EN 779-2002 in relation to air quality?

The role of the CEN Standard EN 779-2002 is specifically to set protocols for testing air filters. This standard addresses the performance of air filters in terms of their ability to capture particulate matter in indoor air, thereby contributing to maintaining air quality. By providing a consistent approach for measuring filter performance, it ensures that air filtration systems are effective in reducing pollutants and enhancing the overall indoor environment. This is crucial for achieving better indoor air quality, which is a key aspect considered in sustainable building practices, particularly within the LEED framework where air quality is directly linked to occupant health and environmental impact.

The other options do not pertain to the EN 779-2002 standard. For instance, standards relating to ecological construction or water quality management are governed by different sets of protocols. Similarly, while energy usage guidelines are important for sustainability, they fall outside the specific scope of air filters and air quality management as addressed by EN 779-2002.
