Learning Objectives

1. Participants will be able to identify several Sustainable Site Strategies:

BioswalesSubsurface DetentionHardscape “Diet”Bioretention BasinsGeothermal Heating and Cooling System SS|D

Learning Objectives

2. Participants will learn which LEED credits can be achieved through Sustainable Site Strategies under the newly adopted 2009 LEED V3 in comparison to the former LEED V2.2.

Sustainable Site Strategies

A. Minimize impact on watershed1) Preserve natural drainage features,

minimize roofs and paving2) Use pervious surfaces and “green roofs”3) Disperse runoff from impervious

surfaces on to adjacent pervious surfaces

4) Drain impervious surfaces to engineered Best Management Practices (BMPs)

B. Conserve or reuse waterC. Conserve energy
