VDI 6027 Blatt 2:2005-11 (R2009)

The purpose of this guideline is to standardise the requirements for the data exchange of CAD systems so far as they communicate with one another in the computer- aided planning process within Building Services (heating, air conditioning, sanitary and electrical systems) and the parties involved in the build. In particular, it describes structures for plant engineering which must be complied with as a minimum requirement in order to allow the recipient to work with the data meaningfully without the need for any additional processing. This involves information that goes beyond the purely geometrical description. At the same time, this guideline establishes conditions whereby this data can be captured, expanded and updated over the various lifecycles of a building, and made available for any desired further applications. The guideline makes a distinction between system components and system networks. For system components, the guideline defines their local allocation, their product description and an open structure within which to enter design parameters. Other data sources are accessed by reference where possible.
