Is it ok just to achieve the minimum score for a level?
It is unwise just to scratch into a level at design stage. If something occurs during the build that affects the score (e.g. some materials could not be obtained from a suitably green source) the post construction review will pick it up and the revised score may mean that you drop to a lower level. This could mean that you are in contravention of a planning condition on your project. If you start with a score above the minimum for the required level then even with the unexpected issue you may still achieve the required level.
