Kaid Benfield of the Natural Resources Defense Council estimated that the carbon emissions associated with the additional miles driven were almost three times higher than before, a change from 0.39 metric tons per person per month to 1.08 metric tons of carbon dioxide per person per month. Speck writes that "The carbon saved by

275-471: A building. Critics such as David Owen and Jeff Speck also point out that LEED certification focuses on the building itself, and does not take into account factors such as the location in which the building stands, or how employee commutes may be affected by a relocation. In Green Metropolis (2009), Owen discusses an environmentally-friendly building in San Bruno, California , built by Gap Inc. , which

330-428: A comparison with emphasis on factors that heavily influence energy consumption. The number of points achieved in this credit is proportional to the predicted energy savings. This method has been criticized for inaccurately predicting actual energy usage. The USGBC admits that "current information indicates that most buildings do not perform as well as design metrics indicate. As a result, building owners might not obtain

385-477: A minimum of $ 2,900 to over $ 1 million for a large project. "Soft" costs – i.e., added costs to the building project to qualify for LEED certification – may range from 1% to 6% of the total project cost. The average cost increase was about 2%, or an extra $ 3–$ 5 per square foot. The application review and certification process is conducted through LEED Online, USGBC's web-based service. The GBCI also utilizes LEED Online to conduct their reviews. Applicants have

1760-571: The building's energy and water use for five years after occupancy (for new construction) or date of certification (for existing buildings). The credit weighting process has the following steps: First, a collection of reference buildings are assessed to estimate the environmental impacts of similar buildings. NIST weightings are then applied to judge the relative importance of these impacts in each category. Data regarding actual impacts on environmental and human health are then used to assign points to individual categories and measures. This system results in

1815-510: The campus. The college had offered $ 102,500 for the alleyway, which had an appraised value of $ 2,500. Following the vote, the Mayor of Washington indicated that one of the three nay votes had reneged on an agreement to accept the offer. Instead of accepting the offer, the City Council wanted to levy a $ 100 annual municipal services fee on all students, a proposal that would have been illegal under Pennsylvania law. The fee proposal never came to

These are weighed using the environmental impact categories of

2200-586: The leading five states (after the District of Columbia ) were Massachusetts, Illinois, New York, California, and Maryland. Incentives can include tax credits, zoning allowances, reduced fees, and expedited permitting. Offices, healthcare-, and education-related buildings are the most frequent LEED-certified buildings in the US (over 60%), followed by warehouses, distribution centers, retail projects and multifamily dwellings (another 20%). Studies have found that for-rent LEED office spaces generally have higher rents and occupancy rates and lower capitalization rates. LEED

2255-440: The marketplace." Critics of LEED certification such as Auden Schendler and Randy Udall have pointed out that the process is slow, complicated, and expensive. In 2005, they published an article titled "LEED is Broken; Let's Fix It", in which they argued that the certification process "makes green building more difficult than it needs to be" and called for changes "to make LEED easier to use and more popular" to better accelerate

2420-425: The option of achieving credit points by building energy models. One model represents the building as designed, and a second model represents a baseline building in the same location, with the same geometry and occupancy. Depending on location (climate) and building size, the standard provides requirements for heating, ventilation and air-conditioning (HVAC) system type, and wall and window definitions. This allows for

2475-431: The transition to green building. Schendler and Udall also identified a pattern which they call "LEED brain", in which participants may become focused on "point mongering" and pick and choose design elements that don't actually go well together or don't fit local conditions, to gain points. The public relations value of LEED certification begins to drive the development of buildings rather than focusing on design. They give
