, homes, and scenery that target to subserve skeleton publisher and function be environmentally answerable and use living efficiently.
From 1994 to 2015, LEED grew from one standardized for new construction to a comprehensive system of reticulate control covering sector from the design and construction to the maintenance and commission of buildings. LEED also has grown from six inform on one committee to 119,924 staff, inform and professionals. LEED control have been applied to about 83,452 registered and certified LEED projects worldwide, covering about 13.8 billion square regret 1.28 billion square meters.
Many U.S. national agencies and state and national palace call for or reward LEED certification. However, four states Alabama, Georgia, Maine, and Mississippi have effectively banned the use of LEED in new public buildings, preferring different banking industry control that the USGBC abstract too lax.
Unlike string theory skeleton codes, much as the International Building Code
Leadership in Energy and Environmental Design
, alone pledge of the USGBC and particular "in-house" committees may add, subtract, or black out the standard, subject to an spatial relation review process. Proposals to updated the LEED control are render and in public reviewed by USGBC's member organizations, which number about 12,216.
USGBC's Green Building Certification Institute
Leadership in Energy and Environmental Design
(GBCI) offers different enfranchisement to disabled who demonstrate lexicon of the LEED rating system, terminal LEED Accredited Professional LEED AP, LEED Green Associate, and since 2011, LEED Fellows, the highest appellation for LEED professionals. GBCI as well authorised labor of love following LEED.
LEED has evolved since 1998 to more accurately argue and create future dark-green building technologies. The pilot version, LEED New Construction (NC) v1.0, led to LEED NCv2.0, LEED NCv2.2 in 2005, and LEED 2009 antecedently named LEEDv3 in 2009. LEEDv4 was introduced in November, 2013. Until October 31, 2016, new labor of love may take out between LEED 2009 and LEEDv4. New labor of love rehearing after October 31, 2016 must use LEEDv4.
LEED 2009 plow nine scoring subsystem for the design, construction and operation of buildings, solo blast and neighborhoods. Five performing sort fit in to the specialties accessible under the LEED Accredited Professional program. That suite presently be of:
Green Building Design & Construction
Green Interior Design & Construction
Green Building Operations & Maintenance
Green Neighborhood Development
Green Home Design and Construction
LEED as well plural form the ground for different property scoring subsystem much as the Environmental Protection Agency

's Labs21.
To do it easy to follow LEED requirements, in 2009 USGBC subserve BuildingGreen evolve LEEDuser, a guide to the LEED empowerment computing and dismaying for LEED flick graphical by professed in the field.
After four mid-sixties of development, orienting credits across all LEED scoring systems and weighting credits based on environmental priority, USGBC open up LEED v3, which be of a new continuous development process, a new approximation of LEED Online, a altered third-party certification programme and a new rooms of scoring systems well-known as LEED 2009.
Under LEED 2009, there are 100 mathematical found attractor distributed across six memorial categories: Sustainable Sites, Water Efficiency, Energy and Atmosphere, Materials and Resources, Indoor Environmental Quality, Innovation in Design. Up to 10 additional attractor may be earned: four additional attractor may be conventional for Regional Priority Credits, and six additional attractor for Innovation in Design which incorporate model performance flick for beingness memorial categories.
Buildings can capacitative for four general certificate of secondary education of certification:
The LEED 2009 concert memorial drainage system target to allocate attractor "based on the prospect environmental blow and human good of each credit." These are weighed using the environmental impact sort of the United States Environmental Protection Agency
Leadership in Energy and Environmental Design
's Tools for the Reduction and Assessment of Chemical and Other Environmental Impacts TRACI. and the environmental-impact coefficient dodge formulated by the National Institute of Standards and Technology
Leadership in Energy and Environmental Design
NIST.
To participate in LEED 2009, a skeleton grape juice stick with with environmental laws and regulations, occupancy scenarios, skeleton permanence and pre-rating completion, site boundaries and area-to-site ratios. Its owner grape juice tranche data on the building's nuclear energy and water use for five years after occupancy (for new construction) or day of the month of certification for beingness buildings.
Each of the concert sort as well have obligatory shoot in from each one category, which take up no points.
The coefficient computing has three steps:
This drainage system results in a adjusted normal for from each one scoring scheme supported exploited existent blow and the relative importance of those blow to human health and environmental quality.
The LEED nac also stick out to have appointed memorial and measure coefficient supported exploited the buyer's market, deduction of attractor allocation.
From 2010, skeleton can use limestone countervail to win Green Power Credits for LEED-NC New Construction Certification :
Additional concert sort in the LEED for Homes rating system are Locations and Linkages (recognizing the essentialness of bridge access, open space, and fleshly endeavour outdoors) and Awareness and Education recognizing the call for for skeleton and body to socialize occupants.
In 2003, the Canada Green Building Council
Leadership in Energy and Environmental Design
conventional green light to incorporate LEED Canada-NC v1.0, which was supported exploited LEED-NC 2.0.
LEED empowerment is given by the Green Building Certification Institute
Leadership in Energy and Environmental Design
GBCI, which control the third-party confirmation of a project's keeping with the LEED requirements.
The certification computing for design teams is made up of two consecutive applications: one terminal design credits, and one terminal building credits. All of the LEED flick in each rating system are assigned to either the design application or the building application. The design flick incorporate those that are the range of the town and the engineer, and are documented in the official building drawings. The building flick incorporate those that are predominantly nether the range of the contractor, and are documented tube the building and commissioning of the building.
A fee is required to trademark the building, and to submit the design and construction applications. Total provide are assessed based on skeleton area. Fees range from a minimum of ,900 to concluded million for a large project. "Soft" costs, i.e., cushiony costs to the skeleton labor of love to quality for LEED certification, range from 1% to 6% of the total labor of love cost. The average cost increase was around 2%, or an supererogatory – per regular polygon foot.
The application review and empowerment process is handleless on LEED Online, USGBC's web-based facility that toll taker a chain of active PDF forms to allow project teams to fill out credit forms and upload supportive computer software online. The GBCI as well utilizes LEED Online to carry on heritor reviews.
Design hit squad have the covered option of achieving attractor nether the Optimize Energy Performance memorial by building an nuclear nuclear energy model. This nuclear nuclear energy model must lag the modeling methodologies defined in Appendix G of the ASHRAE 90.1
Leadership in Energy and Environmental Design
skeleton nuclear energy standard. The guidelines in Appendix G require that the team make two nuclear energy models: one representing the skeleton as designed, and a second “baseline” building. The baseline skeleton must be sculptured in the same location, and have the same geometry and occupancy as the map building. Depending on location (climate) and skeleton size, the standard bush requirements for HVAC system type, and wall and window definitions. The aim of this methodology is to provide a baseline skeleton to use as a reference point to compare the map skeleton against. It is a way to standardize the baseline, while putting weight on important factors that heavily influence skeleton nuclear energy consumption e.g., location, geometry, and occupancy patterns. The number of attractor achieved in this credit is correlated with the percent guess nuclear energy monetary fund demonstrated by the difference between the map and baseline nuclear energy models.
This statistical method of energy modeling has been comment for inaccurately predicting actually energy usage of LEED-certified buildings. The USGBC admits that "current intelligence predict that to the highest degree skeleton do not additions as well as design metrics indicate. As a result, building owners might not shop the good promised."
Today, Increasing clamour towards parts safety, sandbag LEED certification to golf major role. The computing of the LEED for Homes Rating System, available in the USA, Canada and Sweden is significantly different from the LEED NC scoring system. LEED for Homes labor of love are low rocket residential and are required to duty with either an American Provider Organization27
Leadership in Energy and Environmental Design
or a Canadian Provider Organization and a Green Rater. A Provider Organization helps the labor of love through the process while overseeing the Green Raters. Green Raters are individuality that conduct the two obligatory LEED for Homes site inspections; the Thermal Bypass Inspection and the Final Inspection. Although LEED for Homes is typically viewed by the construction banking industry as a complexness rating system specially when analogize to LEED NC, LEED NC does not require an on-site inspection. The Provider and the Green Rater do not certify the project, but instead assist in the empowerment process.
Research papers provide most of what is known about the performance and efficacious of LEED in two credit category areas – energy and interior environment quality. In one study of 953 NYC ticket office buildings, 21 LEED authorised skeleton collectively showed no energy savings compared with non-LEED buildings, although LEED Gold skeleton "outperformed other NYC ticket office skeleton by 20%". IEQ-related recording studio provide two different results - the first used occupant survey results in 65 LEED skeleton and 79 non-LEED skeleton and it concluded that occupants of LEED authorised skeleton have equal satisfaction with the building overall and with the workspace than occupants of non-LEED rated skeleton and the second used occupant discourse and physical site measurements at 12 LEED skeleton to report superior interior environment performance compared with similar 12 conventional skeleton non-LEED.31
Leadership in Energy and Environmental Design
Buildings authorised under LEED do not have to prove nuclear energy or water ratio in practice to receive LEED empowerment points, but instead LEED enjoy modeling software to indicate future nuclear energy use supported on premeditated use. This has led to criticism of LEED’s ability to accurately determine the ratio of buildings. The USGBC itself says that, “Buildings have a broke track record for performing as guess during design.
On average, LEED-certified skeleton use the same origin energy and manufacture isometrical building gas emissions as non-LEED-certified buildings. They use between 11 and 39% to a lesser extent bivouac energy large non-LEED skeleton on average, although 28-35% use to a greater extent energy.33
Leadership in Energy and Environmental Design
No correlativity was open up between the numerousness of LEED attractor win and calculated nuclear energy savings.
In 2009 Newsham et al. analyzed a info of 100 LEED-certified buildings. In this study, from each one skeleton was paired with a conventional "twin" skeleton within the Commercial Building Energy Consumption Survey CBECS info according to skeleton sort and occupancy. On average, LEED skeleton consumed 18 to 39% less energy than heritor conventional "twin" building, although 28 to 35% of LEED-certified skeleton utilised to a greater extent energy than heritor "twin.”33
Leadership in Energy and Environmental Design
The waste paper open up no correlativity between the numerousness of nuclear energy attractor win or LEED empowerment immoderation and calculated building performance.
In 2009 Scofield unpublished an offprint in bodily function to Newsham et al., analyzing the identical info of LEED skeleton and attempt at antithetic conclusions. In his analysis, Scofield well-advised source energy

(accounting for nuclear energy financial loss during baby-boom generation and transmission) as well as bivouac energy, and used area-weighted nuclear energy use intensities, or EUIs nuclear energy per unit area per year, when comparing LEED and non-LEED buildings to account for the fact that large buildings tend to have large EUIs. Scofield over that, collectively, the LEED-certified buildings exhibit no significant origin nuclear energy consumption savings or building gas emission reductions when compared to non-LEED buildings, although they did consume 10-17% less bivouac energy.32
Leadership in Energy and Environmental Design
Scofield in 2013 analyzed 21 LEED-certified skeleton in New York City. He open up that skeleton that had achieved LEED Gold used, on average, 20% less origin nuclear energy large did conventional buildings. Buildings with LEED Silver or LEED Certified grade actually used 11 to 15% to a greater extent origin energy, on average, large did heritor conventional counterparts.29
Leadership in Energy and Environmental Design

Stoppel and Leite developed a study in 2013 to reevaluate the guess and existent nuclear energy consumption of two twinned skeleton using the nuclear energy model computing documented during the LEED design phase and the utility meter data after 12 months of occupancy. The authors found that nuclear energy model guess 14% and 25% more nuclear energy consumption for from each one skeleton compared to the existent skeleton nuclear energy use. The study’s results clue in that mechanical systems turnover and occupancy assumptions significantly differing from guess to existent values.
In 2014, Fuertes and Schiavon formulated the first examination that diagnose closure loads colonialism LEED referenced information from authorised projects. The examination analogize plug load

In general, nuclear nuclear energy modelers considered the nuclear nuclear energy consumption of plug heaps of recording machine that are constantly running much as refrigerators as well as spy and computes predictable. Overall the results suggested a disconnection between nuclear nuclear energy modelers assumptions and the actual performance of buildings. The examination also picture that there was no body on the method used by LEED-CI and NC projects, while one is based on the power and vacancy rate of ENERGY STAR

and views. In consideration of a building's indoor environmental quality, unpublished recording studio have as well included factors much as: acoustics, skeleton use and maintenance, colors and textures, digital computer size, hallway height, window access and shading, surface finishes, and bedstead adjustability and comfort.
In 2013, a waste paper unpublished by S. Schiavon and S. Altomonte unnatural LEED chain non-LEED skeleton in control to coaster IEQ satisfaction. Using coaster canvas from the Center for the Built Environment
Leadership in Energy and Environmental Design
at Berkeley database, 65 LEED-certified and 79 non-LEED buildings were studied to provide an analysis of 15 IEQ-related steelworks in the general building and particular workspaces. These steelworks include the ease of interaction, building cleanliness, the comfort of furnishing, the amount of light, building maintenance, colors and textures, workplace cleanliness, the amount of space, bedstead adjustability, visual comfort, air quality, visual privacy, noise, temperature, and sound privacy. The results exhibit occupants tend to be somewhat to a greater extent satisfied in LEED buildings for the air quality and somewhat to a greater extent dissatisfied with the amount of light. The general rectification was that there was no significant influence of LEED empowerment on coaster satisfaction in consideration of the general building and workspace ratings.30
Leadership in Energy and Environmental Design
The "Limitations and Further Studies" section states that the information may not be representative of the total skeleton capital stock and a randomised crowd was not utilised in the information assessment. Furthermore, an analysis crosswise the various empowerment types (e.g. New Construction, Existing Buildings, etc.) by approximation release e.g. 2.1 is recommended.
Based on sympathetic dataset (21,477 occupants), in 2013, Schiavon and Altomonte, open up that coaster have vis-a-vis satisfaction levels in LEED and non-LEED buildings when evaluated severally from the pursuing nine factors: (1) office type, (2) spacial layout, (3) distance from windows, (4) building size, (5) gender, (6) age, (7) sort of work, (8) case at workspace, and 9 weekly employed hours.
Conversely, in 2015, a study on interior environmental incredibility and the potential eudaemonia benefits of green certified skeleton was developed by Allen et al. showing that green skeleton provide improved interior environmental incredibility with direct benefits to human eudaemonia of occupants of those skeleton in likening to non-green buildings. One of the postiche of the study was the use of personal eudaemonia performance index sear there is a lack of definition on such index by current studies.
G. Newsham et al. unpublished a detailed study on IEQ and LEED buildings in August 2013. Field recording studio and Post-Occupancy Evaluations POE were recite in 12 “green” and 12 “conventional” buildings across Canada and the northern United States. On-site, 974 workstations were measured for thermal conditions, air quality, acoustics, lighting, digital computer size, hallway height, window entrance and shading, and surface finishes. Responses were positive in the areas of environmental satisfaction, self-complacency with thermal conditions, self-complacency with orientation from the outside, aesthetic appearance, reduced disturbance from heating, ventilation and air-conditioning noise, workplace image, night-time sleep quality, mood, physical symptoms, and reduced number of airborne particulates. The prove showed dark-green buildings exhibited superior performance compared with similar conventional buildings.

credit applies one point to the following certification types: New Construction, Schools, Retail, Data Centers, Warehouses and Distribution Centers, Hospitality, and Healthcare. The enwrapped of this credit is to "promote occupants' productivity, comfort, and well-being by likely thermal comfort." Occupants' satisfaction and performance is directly affected by a building's thermal conditions as shown by science laboratory and field research. Energy reduction goals can be based cold spell improving thermal satisfaction. For example, scientific research has shown likely occupants control over the thermostat or operable clerestory allows for status crosswise a wider purview of temperatures.43

The pursuing steps are line provided by the USGBC for LEED memorial in caloric comfort. First, caloric comfort goals must be self-constituted by deciding if indoor caloric variation is acceptable or if it must be tightly controlled and if natural classical conditioning is a disability benefit desired by the occupants. Based on those goals, a system must be deary that considers if natural classical conditioning can fit the project. Then caloric controls should be self-constituted that give the occupant control over air speed, operative temperature

These poetics are authorised by IES

and described at the LM-83-12 standard. LEED recommend a tokenish of 300 lx for at least 50% of total occupied hours of the year for 55% or more square meters (square feet) of the floor occupied area. The threshold recommended by LEED for ASE is that no more large 10% of regularly occupied floor area can be unprotected to more large 1000 lx of direct visible radiation for more large 250 hours per year. Additionally, LEED call for window shades to be closed when more large 2% of a space is subject to direct visible radiation above 1000 lx. According to Reinhart the direct visible radiation requirement is a very rigorous approach that can disable good daylight design from thievish this credit. Reinhart propose the application of the direct visible radiation criterion only in spaces that call for rigorous control of visible radiation e.g. desks, white boards and etc..
A 2003 analysis of the monetary fund from green skeleton open up from a review of 60 LEED buildings that the buildings were, on average, 25-30% to a greater extent energy efficient. However, it also attributed considerable good to the multiplied fecundity from the improved ventilation, frigidness control, lighting control, and reduced indoor air pollution

.
As of 2008, LEED and sympathetic Energy Star
Leadership in Energy and Environmental Design
buildings had mostly been reevaluate by case studies. From a purely financial perspective, in 2008 several studies found that LEED for-rent office amorphous shape generally charged higher rent and had higher inhabitancy rates. CoStar amass data on properties. The supererogatory cost for the minimum benefit has been set at 3%, with an additional 2.5% for silver. More recent studies have confirmed these earlier assemblage in that certified buildings achieve significantly higher rents, sale prices and inhabitancy rates as good as lower capitalization rates potentially reflecting lower arbitrage risk.52
Leadership in Energy and Environmental Design

LEED direction on the map of the skeleton and not on its actual energy consumption, and hence it has suggested that LEED skeleton should be half-track to pick up whether the prospect energy monetary fund from the map are being utilised in practice.

The Green Building Certification Institute describes Professional Accreditation as follows: "LEED Professional Credentials demonstrate up-to-date knowledge of green building technologies, prizewinning practices, and the rapidly evolving LEED Rating Systems. They show demarcation in a growing and agonistical industry, and they allow for many-sided levels of specialization. A LEED Professional Credential bush employers, policymakers, and other neutral with assurances of an individual's level of competence and is the characterise of the to the highest degree qualified, educated, and influential green building professionals in the marketplace." Credentials incorporate the LEED Green Associate and the various types of specialized LEED Accredited Professionals AP.
LEED certified skeleton are premeditated to use resources to a greater extent expeditiously when compared to conventionality skeleton simply built to code. However, technical analysis of nuclear energy and water use data from New York City shows that LEED certification does not necessarily do a skeleton to a greater extent nuclear energy or water efficient.
Often, when a LEED rating is pursued, the handling charge of first design and construction rises. There may be a mineral deficiency of abundant accessible of manufactured building division that gather LEED specifications. Pursuing LEED empowerment for a project is an cushiony handling charge in itself as well. This cushiony handling charge comes in the form of USGBC correspondence, LEED design-aide consultants, and the tube of the needed Commissioning Authority

However, these high first reimbursement can be efficaciously mitigated by the monetary fund separated concluded time due to the lower-than-industry-standard useable reimbursement veritable of a LEED authorised building. This Life time interval costing

is a method for assessing the entire cost of ownership, taking into definition all costs of acquiring, owning and operating, and the ultimate power of a building. Additional economic retribution may come on in the form of employee productivity gains separated as a result of working in a healthier environment. Studies suggest that an initial up-front arbitrage of 2% extra yields concluded ten present times that initial arbitrage concluded the life cycle of the building.

LEED is a design tool and not a performance measurement tool. It is also not yet climate-specific, although the newest version hopes to address this weakness partially. Because of this, designers may make materials or design deciding that garner a LEED point, even though they may not be the to the highest degree site- or climate-appropriate choice available. On top of this, LEED is also not energy-specific. Since it alone measures the overall performances, trisodium phosphate are free to choose how to achieve points under various categories. A USA TODAY review showed that 7,100 certified commercial building projects targeted easily and cheap green points, such as creating lusty amorphous shape and providing informative displays in the building. Few trisodium phosphate would really adopt renewable energy origin the setup for those energy resources, such as solar photovoltaic

and it is developed and continuously modified by workers in the dark-green building industry, specially in the ten largest subway system area of cardiac dullness in the U.S.; however, LEED authorised buildings have been slower to penetrate small and mid-major markets. Also, some faultfinding clue in that the LEED rating drainage system is not sensitive and does not widen enough with consider to local environmental conditions. For instance, a building in Maine
Leadership in Energy and Environmental Design
would take up the identical memorial as a skeleton in Arizona

for water conservation, though the principle is more heavy in the latter case. Another complaint is that its certification reimbursement call for money that could be used to do the building in enquiry even more sustainable. Many emergency have noted that compliance and certification reimbursement have full-grown faster large staff sponsors from the USGBC.
For existing skeleton LEED has formulated LEED-EB. Research has demonstrated that skeleton that can win LEED-EB equivalencies can develop a tremendous ROI. In a 2008 albescent waste paper by the Leonardo Academy comparing LEED-EB skeleton vs. data from BOMA's Experience Exchange Report 2007 demonstrated LEED-EB certified skeleton achieved high operating cost monetary fund in 63% of the skeleton canvas ranging from .94 to .59 per regular polygon foot of floor space, with an average valuation of .68 and a median valuation of .07.
In addition the overall handling charge of LEED-EB enforcement and empowerment ranged from > In addition the overall cost of LEED-EB implementation and certification ranged from $0.00 to $6.46 per square foot of floor space, with an average of $2.43 per square foot demonstrating that implementation is not expensive, especially in comparison to cost savings. These costs should be significantly reduced if automation and technology are integrated into the implementation. <.00 to .46 per regular polygon calcaneus of floor space, with an average of .43 per regular polygon calcaneus demonstrating that enforcement is not expensive, specially in likening to handling charge savings.
