试卷: LEED GA模拟题B[查看] A project team decides to build up instead of out resulting in an increase in the floor area ratio of an office building. What credit might this help earn if the additional land area is turned into a dry pond? A: Brownfield Redevelopment B: Water Efficient Landscaping C: Development Density D: Stormwater Design 参考答案: D
本题解释: Development density is the total square footage of buildings in a particular area divided by acre amount of the same area, expressed as SF/Acre. For example 20,000 SF per acre; If the floor area ratio is increasing by building up instead of out that means the building footprint is decreasing. A smaller building footprint will mean there is more open space available (assuming it doesn\'t get paved).
A dry pond (detention pond) is used to store excess stormwater. Dry ponds are basins whose outlets have been designed to detain stormwater runoff for some minimum time (e.g., 24 hours). The stormwater will slowly seep into the ground or discharge as determined by the pond design to allow pollutants to settle. Unlike wet ponds, these facilities do not have a large permanent pool of water. |
