Can an office that had already been under fit-out be eligible for LEED-Commercial Interiors Certification? The two floors office is located in a 12 story commercial building. The interior work had been concluded two years ago, we have all documentation regarding the materials and design plans. There will be some alteration work, in order to accomplish all prerequisites and achieve the minimum points to get a LEED-CI certification. This new fit-out will increase the existing technologies and add new ones: low flow fixtures, install solar control devices, improve the lighting system; increasing the outdoor air supply, and others. However, we estimate that the fit-out will not interfere in 70% of the existing building and systems, and we will maintain all furniture, wall and partitions. So, can this project be eligible for the certification?
