Hello and thank you ahead of time for your input. 

I have a project that consists of renovating an entire floor of a 7 story office building. The owner of the building is the occupant and will continue to be the occupant of the renovated space. 

The building was certified LEED-NC Gold v3 in 2015 when it was completely renovated previously. The building is expected to recieve LEED EB-OM Gold v3 this year. 

Is the new tenant renovation required in any way to persue LEED certification? If not, are there certain requirements that would need to be followed because the building is LEED?
