GFBS: A PSS DESIGN MODEL APPLIED TO THE BRIEFING PROCESS OF CONSTRUCTION PROJECTS
A building can be considered as a PSS with a product part (i.e. the building) and a service part (i.e. human-intensive activity). Its requirements definition consists inter alia in defining which part will assume the different functions to provide, alone or in an integrated way. Existing design models in architecture do not fully support the service part of buildings. This paper crosses the concepts of PSS, Goal, and FBS approach in a design theory to support such requirements definition. This design theory is illustrated ex post facto on the requirements definition of a school building.
