Indoor Environments directly affect the health and well being of people and are responsible for their productive output. Thus, maintaining the right indoor environmental quality is of paramount importance in any building. Typically, when buildings are designed, architects look at optimization of adequate fresh air ventilation, daylight availability and thermal comfort as primary requirements for well being of occupants. However, with increasing pressures of housing more people in smaller spaces, particularly in dense urban settings, compromises are made in design. Effective IEQ Audit can help to identify areas within buildings which are lacking in the basic requirements of fresh air ventilation, thermal comfort and daylight availability. Going further, IEQ Audits can directly identify measures that can help architects to optimize their designs for higher occupant comforts, thereby saving energy on mechanical and artificial ventilation and lighting systems.
