LEED has evolved since 1998 to more accurately represent and incorporate emerging green building technologies. LEED has developed building programs specific to new construction (NC), core and shell (CS), commercial interiors (CI), existing buildings (EB), neighborhood development (ND), homes (LEED for Homes), retail, schools, and healthcare.
The LEED Green Building Rating System (LEED) is a program that provides third-party verification of green buildings. The LEED program rates commercial buildings, homes, neighborhoods, retail, healthcare, schools, including every phase of the respective building lifecycle, including design, construction, operations, and maintenance.
Low-energy electron diffraction (LEED) is a technique for the determination of the surface structure of single-crystalline materials by bombardment with a collimated beam of low-energy electrons (30–200 eV) [1] and observation of diffracted electrons as spots on a fluorescent screen. LEED may be used in one of two ways:
Over the years, LEED has undergone many changes and is now currently in its fourth iteration, which was launched in late 2013. [26] Taipei 101, the tallest and largest LEED Platinum certified building in the world since 2011. LEED rating systems differ according to the type of the project. [27] The different types of rating systems fall under: [27]
Starting in November, new permit applications for high-rise residential building must submit documentation to achieve LEED certification, and that requirement ratchets up to LEED Silver in 2009 and LEED Gold in 2012. There are also requirements to meet additional LEED standards, nearly equal to those for mid-size commercial buildings.
LEED for Neighborhood Development (LEED-ND), where "LEED" stands for Leadership in Energy and Environmental Design, is a United States–based rating system that integrates the principles of smart growth, urbanism, and green building into a national system for neighborhood design. LEED certification provides independent, third-party ...
LEED has four different levels of certification. All depending on how many credits and points were obtained through the LEED Rating System. There are 100 possible base points plus an additional 6 points for Innovation in Design and 4 points for Regional Priority. Buildings can qualify for 4 types of certification: Certified: 40-49 Points
A Zero-Energy Building (ZEB), also known as a Net Zero-Energy (NZE) building, is a building with net zero energy consumption, meaning the total amount of energy used by the building on an annual basis is equal to the amount of renewable energy created on the site [1] [2] or in other definitions by renewable energy sources offsite, using technology such as heat pumps, high efficiency windows ...
