LEED vs Estidama

Occupant satisfaction in LEED and non-LEED certified buildings

Occupant satisfaction with indoor environmental quality (IEQ) in office buildings has been positively correlated to self-estimated job performance and, potentially, to overall company productivity. LEED is a voluntary, consensus-based, market-driven program that provides third-party certification of green buildings, contributing to promote sustainability into the mainstream of building design a...

Differentiation in Adoption of Environmental Standards: LEED

Understanding how firms adopt voluntary quality or environmental standards is important for designing such programs and evaluating their success. We study the adoption of LEED (Leadership in Energy & Environmental Design), an internationally recognized environmental building certification system. LEED offers four levels of certification, corresponding to greater investments in green building te...

Nanotip-based photoelectron microgun for ultrafast LEED

We present the design and fabrication of a micrometer-scale electron gun for the implementation of ultrafast low-energy electron diffraction from surfaces. A multi-step process involving photolithography and focused-ion-beam nanostructuring is used to assemble and electrically contact the photoelectron gun, which consists of a nanotip photocathode in a Schottky geometry and an einzel lens for b...

Photoemission and LEED characterization of Ni2P(0001)

Ion bombardment of Ni2P(0 0 0 1) produces a disordered, Ni-rich surface. For annealing temperatures above 450 K, long range ordering occurs, and the surface Ni/P ratio decreases. Annealing above 700 K produces an ordered (1 · 1) hexagonal surface with a composition near that expected for a simple stoichiometric termination of the bulk structure. Variations in photoemission spectra are observed ...
