<div><div dir="ltr"><span>Dear eQuesters,</span><div><br></div><div>I am working on a LEED certification for one building in an industry park. The park has a solar PV system serving several buildings. So I do not think I can simulate the PV systems directly in eQUEST to get its share to the LEED target building. My question is how to estimate the PV generated electricity to my building? Should I prorate the PV electricity based on those buildings' energy use, or there is a better way to do the calculation/estimation in the design phase? Any comment is appreciated!</div><div><br></div><div>Best regards,</div><div><br></div><div>Zarah</div> </div></div>
