- Measured to the internal dominant face
- Reported on a component by component basis for each floor
What is IPMS 3A Residential?
External measurement of area in exclusive occupation (similar to GEA)

What is IPMS 3C Residential?
Internal measurement of area in exclusive occupation (similar to EFA)
- Excluding the floor areas occupied by full-height, permanent, internal walls and colums
- Measured to the IDF and finished surface of full height internal walls
What is the difference between GEA and IMPS 1 Residential?
