The series of guideline VDI 6028 offers a method allowing for an objective and holistic evaluation of offers for building automation.

For a building project, lists allow to select when and what criteria have to be observed at a given time. These lists can be supplemented by orderers' specitications in all cases. The guideline is addressed to orderers, property and technical planners, executing companies, users and operators. This guideline is only valid in conjunction with VDI 6028 Part 1.
