The most common indoor pollutants monitored in DCV ...
Indoor air quality ( IAQ) is the air quality within buildings and structures. Poor indoor air quality due to indoor air pollution is known to affect the health, comfort, and well-being of building occupants. It has also been linked to sick building syndrome, respiratory issues, reduced productivity, and impaired learning in schools.
The Indoor Environmental Quality Global Alliance (IEQ-GA) was initiated in 2014 [1] [2] [3] aiming to improve the actual, delivered indoor environmental quality in buildings through coordination, education, outreach and advocacy. The alliance works to supply information, guidelines and knowledge on the indoor environmental quality (IEQ) in ...
Step 1) Judge the applicability of displacement ventilation. Step 2) Calculate summer design cooling load. Step 3) Determine the required flow rate of the supply air for summer cooling. Step 4) Find the required flow rate of fresh air for acceptable indoor air quality. Step 5) Determine the supply air flow rate.
Household air pollution ( HAP) is a significant form of indoor air pollution mostly relating to cooking and heating methods used in developing countries. [1] Since much of the cooking is carried out with biomass fuel, in the form of wood, charcoal, dung, and crop residue, in indoor environments that lack proper ventilation, millions of people ...
AIRLOG is a European Union FP7 project that was scheduled to run from 1 February 2012 to 31 January 2014. [1] The aim of AIRLOG was to develop technology that would assist auditors of indoor air quality (IAQ) and educate the public about IAQ. [2] AIRLOG was to also create an integrated platform for IAQ audit management. [3]
The guidelines offer guidance about these air pollutants: particulate matter (PM), ozone (O 3 ), nitrogen dioxide (NO 2 ), sulfur dioxide (SO 2) and carbon monoxide (CO). [2] The WHO first released the air quality guidelines in 1987, then updated them in 1997. [2] The reports provide guidelines intending to give guidelines to reduce the health ...
