Pilot credit Vs LEED V4

Javier,
I’m sure everyone has a lot of opinions, but here are a few basic things that come to mind:
1. Start early. This credit should be used to shape the design, not to retroactively justify a reference building. Starting early lets you explore what is causing the impacts in your design, and then figure out how to minimize them.
2. Be wary of the “parametric” building designs / options in some programs where you input some basic geometry and framing parameters and the program generates a bill of materials. Those can be helpful for VERY rough comparisons, and perhaps for component placeholders if you are not optimizing that part of the system. However, I have found them to be too coarse to model the part(s) of the system you are trying to optimize to achieve impact reductions. Also, with BIM models today it is relatively easy to extract your actual quantities.
3. Engage the professional designing the parts of the system that you are optimizing. For example, if your strategy involves structural optimization make sure your structural engineer is involved, similarly for enclosure and the enclosure designer / engineer.
I hope that helps.

Really interesting. Thanks for you opinion.

Agree with everything Dirk said above!
