The tunnel uses a combination of portal fans and reversible jet engines to ensure proper air flow and air quality throughout the tunnel.
Airplane ventilation systems are primarily designed to ensure proper air pressure inside the cabin, with air quality a secondary consideration.
Natural ventilation is believed to be capable of enhancing indoor air quality through proper passive designs.
Proper stoves may improve indoor air quality by 85%.
In addition,the sheer number of cars which include both SUVS and old rickety imported passenger cars with poor emission (unofficial numbers estimate 300,000 in UB) sitting idle in traffic caused by the lack of proper roads contributes significantly to poor air quality.
A new technique, firstly applied to the industrial environment, based on the passive reactive monitoring of proper coupons is also proposed for monitoring air quality in museums.
Proper values of hydro-thermal parameters and good air quality indoors are known to have a great influence on human comfort, health and performance, and children are particularly susceptible to poor indoor air quality.
Proper estimation of ship emissions at berth is crucial for understanding the impact of shipping emissions on air quality and health in harbour cities as well as for a proper evaluation of the impact of abatement measures such as shore-side electricity and/or restrictions of sulphur content for shipping fuels to be used in ports.
This study proved that good indoor air quality can be achieved by careful design, choice of proper materials and equipment, and on high-quality construction.
Theoretically, the proper combination of turbine ventilator and natural ventilation will help tremendously the indoor air quality while it will also decrease the reliance on air-conditioning and thus reduce the energy consummation.
