IMPACT is a simple-to-use modelling tool to enable you to estimate the concentration of the reactive air pollutants nitrogen dioxide, ozone and sulphur dioxide inside buildings.

It is a steady state-model that calculates the average long-term concentration of pollutants using a mass balance equation.

The IMPACT software was developed in the European Commission FP5 Research Project Innovative Modelling of Museum Pollutants and Conservation Thresholds.

The software and these pages are maintained by the UCL Centre for Sustainable Heritage.
