COBie parameters within the National BIM Library objects

In response to question on this blog from Rahul Shah to the post "NBL - LRUG"...

The COBie parameters that will be included within National BIM Library objects are as follows. All are type parameters unless stated otherwise. These are from COBie version 2.26, but it is our understanding the the UK Government COBie file format will be slightly different from this and will be published at the end of Q1 this year. National BIM Library will be adjusted to reflect any changes.

The best place for information on this is:

The above page has links to YouTube lecturers from Bill East and also sample files (screenshots below) that include model files, IFC exports and COBie exports in MS Excel format.
