The Requirements Brief

A Requirements Brief is key occupier document that captures all desired sustainability principles and design requirements of a fit-out. It should seek to cover the whole project life-cycle and be developed as early as possible. It serves as reference document at key project stages and will evolve to become more refined and detailed through the course of the fit-out project.

A clear, concise requirements brief, that develops over time can:

To support the development of a Requirements Brief, a Requirements Brief Framework is included to guide occupiers through this process of identifying and recording sustainability design principles.

The table below is a summary of the Requirements Brief Framework providing principles for considerations structured around a set of sustainability related aspects.
