Solar PV Assessment /Net Zero Energy Planning

Estimated Annual Building Energy Use:

​

3,300,000 – 3,500,000  kWh

​

Based on EUI

KBtu/SF/Yr.

​

Solar PV Analysis caveats:

  • Sizing and quantities are PRELIMINARY and subject to change
  • Include a 10% margin of error
  • Preliminary HVAC layouts: subject to change with impact available roof areas and final PV layout: location, clearances, roof screens, etc.

**Notes:

  1. The Simulated Total Annual Production values are PRELIMINARY and represent the highest possible yield of the modeled system. Values are subject to change as the system's design (layout, stringing, shading, roof equipment screens, etc.) advances that will impact the final Solar PV sizing. The estimated total capacity with a 10% margin of error has been calculated.
  2. The assessments take into the maximum total roof areas allocated for Solar PV within the preliminary roof equipment assessments. They are subject to reduction/adjustments in area available, pending HVAC design layouts/walkways, paths, and setbacks, and roof screens. They do take into account the 10-15' high shading from the HVAC equipment areas, shading from the buildings on the canopies, and canopy-to-canopy shading.
