             comes into contact with the project, which includes owners, designers, occu-
             pants, and society as a whole.
                These benefits do not come without a cost, however. Currently within the
             industry, green buildings cost more to both design and construct when com-
             pared to conventional buildings. These increased costs typically represent
             initial upfront costs, which are incurred at the start of the project. However,
             these initial cost increases can be minimized by the economic gains associ-
             ated with constructing a LEED-certified green building. These economic
             gains can take the form of anything from productivity gains to decreased life-
             cycle operating costs. Studies have suggested that an initial up front invest-
             ment of 2 percent can yield more than ten times the initial investment over
             the life cycle of the building. From this perspective, there is no initial cost. In
             fact, the initial cost is actually an investment.
                Although the deployment of the LEED Standard has raised awareness of
             green building practices, its scoring system is skewed toward the ongoing
             use of fossil fuels. More than half of the available points in the standard sup-
             port efficient use of fossil fuels, whereas only a handful are awarded for the
             use of sustainable energy sources. Further, the USGBC has stated support for
                                                                                                               ptg
             the 2030 Challenge, an effort that has set a goal of efficient fossil fuel use by
             2030. Despite its broad acceptance, mounting scientific evidence suggests
             that a more aggressive program of sustainable energy deployment is required
             to protect the climate than that promoted by the LEED Standard and the
             USGBC.

             Certification

                Different LEED versions have varied scoring systems based on a set of
             required prerequisites and a variety of credits in the six major categories pre-
             viously listed. In LEED v2.2, for new construction and major renovations for
             commercial buildings, there are 69 possible points, and buildings can qualify
             for four levels of certification:

             ■ Certified: 26–32 points
             ■ Silver: 33 –38 points
             ■ Gold: 39–51 points
             ■ Platinum: 52–69 points


                LEED certification is obtained after submitting an application document-
             ing compliance with the requirements of the rating system, as well as paying
