2. Indoor air quality - Wikipedia

   en.wikipedia.org/wiki/Indoor_air_quality

   Since indoor air pollutants can adversely affect human health, it is important to have real-time indoor air quality assessment/monitoring system that can help not only in the improvement of indoor air quality but also help in detection of leaks, spills in a work environment and boost energy efficiency of buildings by providing real-time ...

   Risks from the Covid-19 pandemic and increasingly intense wildfire seasons sparked interest in air purifiers as a tool to keep indoor air healthy. But experts say they can be just as important to ...

6. Building airtightness - Wikipedia

   en.wikipedia.org/wiki/Building_airtightness

   The relationship between pressure and leakage air flow rate is defined by the power law between the airflow rate and the pressure difference across the building envelope as follows: [16] q L =C L ∆p n. where: q L is the volumetric leakage airflow rate expressed in m 3 h −1; C L is the air leakage coefficient expressed in m 3 h −1 Pa −n

7. Duct leakage testing - Wikipedia

   en.wikipedia.org/wiki/Duct_leakage_testing

   A duct leakage tester is a diagnostic tool designed to measure the airtightness of forced air heating, ventilating and air-conditioning (HVAC) ductwork. A duct leakage tester consists of a calibrated fan for measuring an air flow rate and a pressure sensing device to measure the pressure created by the fan flow.
