LEED-AP-BD+C Exam Dumps : LEED AP Building Design + Construction (LEED AP BD+C)

The average flush rate for a dual flush toilet is calculated by weighting the high and low flush rates according to the frequency of use. According to the LEED Reference Guide for Building Design and Construction1, the frequency of use for male and female occupants is assumed to be as follows:

Male full flush: 1 time per day

Female full flush: 1 time per day

Male low flush: 2 times per day

Female low flush: 2 times per day

Therefore, the average flush rate for a dual flush toilet with a high flush rate of 1.6 gpf (6 lpf) and a low flush rate of 1.05 gpf (4 lpf) is:

6(1×1.6)+(1×1.6)+(2×1.05)+(2×1.05)​=1.19 gpf(4.5 lpf)

Detailed Explanation:

To achieve three points under the Rainwater Management credit, projects must manage the 95th percentile of regional rainfall events on site. This approach minimizes the impact of stormwater runoff on local watersheds and supports the use of low-impact development (LID) techniques such as bioswales, green roofs, and rain gardens.

Achievement of the Location and Transportation Credit, Surrounding Density and Diverse Uses may be affected by the move of the main entrance to the opposite side of the building. This is because the credit requires that the project be located within a minimum density area and within walking distance of diverse uses1. The walking distance is measured from a main functional entry of the project building to the diverse use entry1. If the main functional entry is moved, the distance to the diverse uses may change and affect the credit achievement. The other credits are not affected by the move of the main entrance, as they are based on the location of the project site, not the building entry. The Location and Transportation Credit, High-Priority Site rewards projects that are located on sites that are previously developed, infill, or adjacent to existing development2. The Location and Transportation Credit, Sensitive Land Protection rewards projects that are located on sites that do not contain sensitive land features such as prime farmland, wetlands, or habitats3. The Location and Transportation Credit, LEED for Neighborhood Development Location rewards projects that are located within the boundary of a LEED for Neighborhood Development certified plan4.
