Dear All,

One of our clients is considering the possibility of certifying an addition to an existing airport terminal and asked us to perform a preliminary evaluation of the potential LEED score. The idea is to limit the scope of the certification to the addition, excluding the existing building from the certification process.

The addition will be physically connected to the existing building. However, according to LEED Minimum Program Requirements, “Buildings that are physically connected by programmable space are considered one building for LEED purposes unless … they are a newly constructed addition”. My interpretation is that, as the addition is a new construction, it can be certified as an independent building. My question is: are there any specific LEED requirements and / or conditions that must be met by the addition in order to achieve LEED certification ? Where can I find guidance on this ?

Thank you in advance.
