What is green due diligence and why would a prospective buyer, tenant, or lender bother with it? As in other areas of the green revolution, the answer ranges from advocacy to dollars.

Many organizations, such as federal agencies, national tenants, lenders, and investors, now have green requirements for new leases, loans, and purchases. They have made the policy judgment that they want the buildings that they lease, acquire, or finance to be green. They are advocates of green. Hence, before leasing, buying, or lending, they conduct due diligence to verify the “greenness” of a property.
