Sammendrag
The average human spends about 90 % of their life indoors. This has led to an increased focus on IAQ
including TVOC concentrations, as the latter can be up to ten times higher indoors than outdoors.
Sources of TVOC must be identified and measured so that measures can be taken to ensure good IAQ.
This study has researched the use of BIM for calculation of the indoor TVOC concentrations and
developed an add-in in Autodesk Revit for this purpose. There are few earlier studies that have used
BIM to assess TVOC concentration despite the number of analytical models developed for determining
emissions and concentrations. Environmental building standards and labelling schemes have
requirements for emission levels which give the manufacturers an incentive to perform tests and
provide documentation. The add-in used static TVOC concentration calculation and emission data from
building materials to perform a calculation in the Revit environment. This has shown to be a simple
method, but there is also a need for further development of the program to make this calculation
manageable and simple to use for architects and engineers.
