Replace the first paragraph with the following:LEED offers additional resources for LEED project teams on the USGBCwebsite, at www.usgbc.org/projecttools.

In the sixth row (Lavatory faucet) replace the duration (sec) of 15 with 30; add a superscript "b" next to "Lavatory faucet" and add note "b" below table: "Default duration for the metering type / autocontrol faucet is 15 seconds for the baseline and 12 seconds for the design case."

Replace the section text with the following:This prerequisite is limited to savings generated by the following water-using fixtures and fixture fittings as applicable to the project: water closets, urinals, lavatory faucets, showers, kitchen sink faucets and pre-rinse spray valves, as shown in Table 1.

In alphabetical order, add the term, "Roof area is the area of the uppermost surface of the building which covers enclosed Gross Floor Area, as measured when projected onto a flat, horizontal surface (i.e. as seen in Roof Plan view). \'Roofs\', or portions of roofs, covering unenclosed areas (e.g. roofs over porches and open covered parking structures) are not included in the areas used to evaluate compliance with roof measures in Options 2 and 3, though they may be applicable to nonroof measures in Options 1 and 3."

In alphabetical order, add the term "An appurtenance is any built-in, nonstructural portion of a roof system, such as skylights, ventilators, mechanical equipment, partitions, and solar energy panels."

Add "skylights" to the list of things deducted from the roof area so that the sentence reads, "Determine the area of the roof covered by mechanical equipment, solar energy panels, skylights, and other appurtenances, and deduct these areas from the total roof surface area."
