US Green Building Council LEED-AP-Homes Exam - Topic 5 Question 8 Discussion

The LEED for Homes Rating System (v4) encourages the use of native plants in the Sustainable Sites (SS) Credit: Site Development -- Protect or Restore Habitat and Water Efficiency (WE) Credit: Outdoor Water Use to enhance environmental benefits, including support for local ecosystems.

According to the LEED Reference Guide for Homes Design and Construction (v4):

SS Credit: Site Development -- Protect or Restore Habitat (1--2 points)

Using native plants in place of conventional turf grass increases native wildlife habitat by providing food, shelter, and breeding areas for local species, supporting biodiversity.

The LEED v4.1 Residential BD+C rating system confirms:

SS Credit: Site Development -- Protect or Restore Habitat

Native plants enhance native wildlife habitat by creating ecosystems that support local fauna, unlike turf grass, which offers minimal ecological value.

The correct answer is native wildlife habitat (Option B), as native plants are adapted to local conditions and support indigenous species, unlike turf grass.

Why not the other options?

A . Fertilizer demand: Native plants typically require less fertilizer than turf grass, which often needs regular fertilization.

C . Irrigation demand: Native plants reduce irrigation needs compared to turf grass, which requires more water.

D . Pesticide demand: Native plants are more resistant to local pests, reducing pesticide use compared to turf grass.

The LEED AP Homes Candidate Handbook emphasizes SS credits, including habitat restoration, and references the LEED Reference Guide for Homes Design and Construction as a key resource. The exam is based on LEED v4, ensuring the relevance of native plants for wildlife.
