The APP uses ‘Snapshot data’ that is data taken at the time of inspection, the data being entered by the user using relatively low-cost surveying equipment. The APP requires the user to input just ‘5’ parameters, following which it will calculate the condition of the internal environment. The APP evaluates the psychometric properties of the air and assesses the results against an ’Indoor Air Quality Matrix’(IAQM).

Whilst snapshot data only reflects the conditions at the time of the inspection, experience has shown that a comparison of the data taken at the initial inspection with that taken after any rectifications have been made very frequently confirms the problems have been rectified, thus providing a very cost effective and measured solution.

Thus, to get the best out of the APP it is best used as a benchmark in a ‘before’ and ‘after’ scenario where the impact of any changes can be measured after the initial assessment. To do this simply act upon any suggestions based on the outcome of the initial assessment (see -Interpreting the results) and simply repeat the same process of data collection after any improvements have been made.

The Air Quality Matrix presents the results in an easy to interpret points score system (<6 poor - >13 Excellent) with colour coded traffic light array of red (poor) – green (good). The Matrix provides a total IAQ Score out of ‘15’.
