• 25 kBtu/ft2/yr for standard office space occupant density and data center
loads
• Demand side energy use goal, not including renewables
• Normalized up to 35.1 kBtu/ft2/yr for better space efficiency and to account for full data
center load
• On site renewables sized to offset site energy use to reach net zero annual
use References:
