As part of this credit the Investor has to confirm that "All open space that is counted toward this credit will be preserved for the life of the building". My client wants to apply for this credit, there is enough open space and there are no future plans to change it. However you never know what can happen in the future and if in some years someone will need to change the open space. What will happen if the area of open space will change after some years of building certification? Can the certification be revoked or the project would just loose one point and would keep the certification level if there is a sufficient number of points for it (after substracting the point for this credit)?
