Aim for Maximum Efficiency

Reference: Gertsakis et al, Better Business, Cleaner World: A Guide to EcoRedesign, Centre for Design at RMIT, 1997.

All resource-consuming systems have a maximum theoretical efficiency. Generally speaking this efficiency can never actually be achieved, but using it as a benchmark allows the designer to more easily identify areas of inefficiency and so make continuous improvements. It is likely that more significant improvements will be achieved than if the target is set below the theoretical maximum.
