Green Labeled Buildings:
◦ Achieve Higher Rents: 7.3% to 17.3%
Energy Star: 7.3% to 8.6%, LEED: 15.2% to 17.3%
◦ Sell at Significant Premium: $30/ Sq. ft. to $129/ Sq. Ft.
Energy Star: $30/ Sq. Ft., LEED $129 / Sq. Ft.
Factors Driving Higher Rent & Valuations:
◦ Unique Visual Appeal Attracting Tenants >> Occupancy
◦ Reduction in Operating Expenses >> Average Rent
