Hello to all,

I have following issue I have a LEED project that is certified as LEED Gold under LEED 2009 NC changes usage.

 The project   received the certification at 2015. Now the owner wants tο change usage of the building and add a gas station and a car-painting  garage. The problem is that there will be hazard material used, that will actual affect building;s gold certification.

What are the Leed limitations on this matter? Is there any recertification required? Once a project NC (New Construction) receives its certification, the certification applies for ever?

Thank you for your answers
