Think of GreenPoint Rated as a report card for a home. There are two versions of the system, one for new construction and one for existing homes, thus the Green Point system can be used to help upgrade the energy efficiency of homes that have already been constructed and occupied. A GreenPoint Rated home is graded on five categories:
The Green Building Initiative
("GBI") oversees Green Globes
in the United States. GBI is an accredited standards developer under the American National Standards Institute (ANSI) and has begun the process to establish Green Globes as an official ANSI standard. When compared to LEED, Green Globes' appeal may be enhanced by the flexibility and affordability the system may provide while simultaneously providing market recognition of a building’s environmental attributes through a recognized third-party verification.
According to a study by the University of Minnesota that compared LEED with Green Globes, the study found that the systems were very similar. LEED was more rigorous, rigid and quantitative whereas Green Globes was also rigorous, but more flexible and primarily focused on energy efficiency as a goal.
is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy helping us all save money and protect the environment through energy efficient products and practices.
EPA provides an innovative energy performance rating system which businesses have already used for more than 130,000 buildings across the country. EPA also recognizes top performing buildings with the ENERGY STAR.
NAHB Green's National Green Building Standard
In 2007 the National Association of Home Builders (NAHB) and the International Code Council (ICC) partnered to establish a much-needed and nationally-recognizable standard definition of what is meant by "Green Building."
A consensus committee was formed to develop this standard in compliance with the requirements of the American National Standards Institute (ANSI). The resulting ANSI approved ICC-700-2008 National Green Building Standard, promoted by the nonprofit NAHB Green
, defines green building for single and multifamily homes, residential remodeling projects and site development projects while still allowing for the flexibility required for regionally-appropriate best green practices.
Similar to the NAHB Model Green Homebuilding Guidelines, a builder, remodeler or developer must incorporate a minimum number of features in the following areas: energy, water, and resource efficiency, lot and site development, indoor environmental quality, and home owner education. The more points accrued, the higher the score.
The National Green Building Standard
is the first residential green building rating system to undergo the full consensus process and receive American National Standards Institute approval. The four threshold levels - Bronze, Silver, Gold, and Emerald - allow builders to achieve entry-level green building, or the highest level of sustainable "green" building incorporating energy savings of 60% or more. Single-family & multi-unit homes, residential remodeling projects, and site developments are all covered in the Standard.
