[9] Developed by the non-profit U.S. Green Building Council (USGBC) it includes a set of rating systems for the design, construction, operation, and maintenance of green buildings, homes, and neighborhoods which aims to help building owners and operators be environmentally responsible and use resources efficiently. However, analysis of energy and water use data from New York City shows that LEED certification does not necessarily make a building more energy or water efficient. [61] This new concept of Kartal, has been the starting point of the innovations and design for the high quality building systems in this old industrial transformation region. [20] and the environmental-impact weighting scheme developed by the National Institute of Standards and Technology (NIST). ( Log Out / Based on similar dataset (21,477 occupants), in 2013, Schiavon and Altomonte,[47] found that occupants have equivalent satisfaction levels in LEED and non-LEED buildings when evaluated independently from the following nine factors: (1) office type, (2) spatial layout, (3) distance from windows, (4) building size, (5) gender, (6) age, (7) type of work, (8) time at workspace, and (9) weekly working hours. A Provider Organization helps the project through the process while overseeing the Green Raters. [91], In June 2013, the USGBC announced a program called LEED Earth that refunds LEED certification fees to the first LEED-certified project in the countries that so far lack one. In one study of 953 NYC office buildings, 21 LEED certified buildings collectively showed no energy savings compared with non-LEED buildings, although LEED Gold buildings "outperformed other NYC office buildings by 20%". [89], The state of Michigan is considering tax-based incentives for LEED buildings. Each of the performance categories also have mandatory measures in each category, which receive no points. Its extensive use of KNX technologies to automate the building's environmental controls has set the benchmark for sustainable buildings.
[37] IEQ-related studies provide two contrasting results - the first used occupant survey results in 65 LEED buildings and 79 non-LEED buildings and it concluded that occupants of LEED certified buildings have equal satisfaction with the building overall and with the workspace than occupants of non-LEED rated buildings[38] and the second used occupant interviews and physical site measurements at 12 LEED buildings to report superior indoor environment performance compared with similar 12 conventional buildings (non-LEED).

To see all meanings of LEED, please scroll down. [39], Current latest study published in 2017, by Altomonte, Schiavon, Kent and Brager, specifically investigated whether a green rating leads to higher occupant satisfaction with IEQ. It is the largest LEED industrial complex in Nevada. There are some possible explanations. It earned a LEED Platinum rating in 2012 and received one of the highest scores by percentage of total points earned in any LEED category, making it the "greenest" building in Pennsylvania and in the top ten greenest in the world. From a purely financial perspective, in 2008 several studies found that LEED for-rent office spaces generally charged higher rent and had higher occupancy rates. [57] On the point of the high rise skyscraper design, such as with the same idea of all the possible glass facade buildings, there is a great opportunity to consider for the innovative use of glass facade systems in terms of gaining energy from the solar technology.
It is a way to standardize the baseline, while putting weight on important factors that heavily influence building energy consumption (e.g., location, geometry, and occupancy patterns). As a result, the USGBC has continued to streamline and modify the LEED certification process.
