What are the two options for Indoor Air Quality Assessment?

The two options for Indoor Air Quality Assessment are flush-out and air testing.

Flush-out involves bringing in a large amount of outdoor air into the building to dilute and remove contaminants that may have accumulated during the construction process. This is particularly important in new buildings or major renovations, as volatile organic compounds (VOCs) and other harmful substances can be present due to new materials. The procedure typically aims to achieve a certain air exchange rate over a defined period, ensuring that any residual pollutants are effectively minimized before the building is occupied.

Air testing, on the other hand, involves sampling the air quality within the building to assess the concentration of specific contaminants. This can include testing for VOCs, particulate matter, carbon dioxide levels, and other air quality indicators. By conducting air tests, one can identify any potential issues that may affect occupant health and comfort, enabling the implementation of corrective measures if necessary.

These two options ensure a comprehensive approach to assessing and improving indoor air quality, which is a critical component of building design and performance.
