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 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.
Here, this is done in a typical LEED set-up, however, in LEEM, there are complicated electron optics that allow for imaging of the resultant diffraction patterns and hence, the surface of the sample. Kinematic or elastic backscattering occurs when low energy (1-100 eV) electrons impinge on a clean, well-ordered crystalline specimen.
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 ...
Starbucks has achieved LEED certificates in 116 stores in 12 countries. Starbucks has even created a portable, LEED certified store in Denver. It is Starbucks' goal to reduce energy consumption by 25% and to cover 100% of its electricity with renewable energy by 2015. [6]
