Abstract: In this technical report, preliminary graphical models spanning approximately 1 MHz to 30 GHz are developed for commercial and residential building attenuation. The models are least-square fits to the data available from the open literature. An estimate of the mean attenuation through the exterior wall can be made for most of the range of the models.

A measurement plan for verification and improvement of the graphical models is outlined, and an example of its application to residential houses at lower frequencies is provided.

The result of a literature review based on 31 references provides additional information for detailed applications. For this purpose, summarizing tables and figures are cross-referenced to primary sources of measurement data.
