Innovating Leases to be green is simply the modification of clauses to align the financial interests of building owners and tenants so both have an incentive to save energy and make cost-effective upgrades. This can help both tenants and landlords save money, conserve resources, extend the lifetime of equipment, and operate more efficiently. These are also known as energy-aligned leases, high performance leases, or energy-efficient leases, according to DOE's press release. The U.S. Department of Energy (DOE) has developed a Green lease libraryto help the commercial building sector implement green leases—rental agreements that encourage energy efficiency.
