SO A GREEN BUILDING….
uses less water,
optimizes energy efficiency
conserves natural resources
generates less waste
provides healthier spaces for occupants
as compared to a conventional building
Evolution of Design
Limited daylightNo operable windows
Materials contaminate indoor airSimultaneous heating and cooling
People overly hot, overly coldNo individual control over comfortSimultaneous water disposal/use
$$$ spent for disposalReliance on the automobile
Built-in obsolescence

The impact categories, formerly credit weightings, are the environmental issues that LEED projects aim to address.
http://www.usgbc.org/resources/leed-v4-impact-category-and-point-allocation-process-overview
The certification levels are LEED® Certified™, Silver, Gold, and Platinum.
The project team and owner will be sent a formal certificate of recognition, details about ordering a LEED plaque, and guidelines for project promotion and submitting project photography.
There are three levels of LEED credentials individuals can choose from based on their level of expertise and experience: LEED Green Associate, LEED AP (Accredited Professional), and LEED Fellow.
