A Review paper on Improving the Indoor Air Quality (IAQ) in green and conventional buildings using sustainable materials.

This paper review the methods of improving the indoor air quality in buildings using a sustainable and effective material. Indoor air quality is the quality of the air inside our buildings and it is one of the important parameters to be adopted for the safe and healthy life of the occupants ,and sustainable materials are those materials which are being produced and used in a required volumes but without depleting the available non renewable resources and without disrupting the established equilibrium state of the environment. Studies found out that people spent 90 percent of their time indoors and because of poor indoor air quality many are having symptoms of sick building syndrome, therefore various researchers are sensing the need and urgency of finding out an effective and economical methods in improving the quality of the indoor air. The methods which have been discussed in this paper are biofiltration technology, a plant based technology which has been adopted for many years in improving the indoor air; photocatalytic paint- an innovative paint material which helps in the degradation of the air pollutants such as; energy recovery ventilators- a system that helps to remove the stale and contaminated air and allowing clean and fresh air to enter our rooms, and; UV technology- a technology which has been adopted in different situations, is found out to be an effective method in deactivating various bacteria and viruses which may enter our buildings. The sample indoor air quality report of a building is included in this study, and is compared with various guidelines from WHO and ASHRAE and was found to be in accordance with it.
