59
By what amount can HEAT ISLANDS elevate temperatures in urban area?
10 degrees F or more
60
Heat islands impact what LEED category(s)?
Sustainable Sites (SS) and Energy and Atmosphere (EA). Heat islands increase temperatures resulting in the need for more air conditioning (and more energy to cool the air).

The area on a project site used by the building structure and defined by the perimeter of the building plan.
64
What is light pollution?
Waste light from building sites that produces glare, is directed upward to the sky, or is directed off the site. Waste light does not increase nighttime safety, utility, or security and needlessly consumes energy
65
What is a benefit of locating a project near mass transit?
Reduced automobile use which reduces automobile emissions.
66
What is a GREENFIELD site?
A site not previously developed or graded that could support open space, habitat, or agriculture.
67
What are examples of IMPERVIOUS surfaces?
Parking lots, roads, sidewalks, and plazas.
68
How is development density calculated?
By drawing a radius from the project building
69
What is the purpose of locating a project in an area with DIVERSE USES?
Locating near diverse uses promotes walking which helps to limit urban sprawl and reduces automobile use.
70
What is a DIVERSE USE?
A distinct, officially recognized business, nonprofit, civic, religious, or governmental organization, or dwelling units (residential use) or offices (commercial office use). It has a stationary postal address and is publicly available. It does not include automated facilities such as ATMs, vending machines, and touchscreens.
71
How are diverse uses identified for a project?
By walking distance from the project site.
72
What helps reduce the heat island effect?

A site that was previously built on, has been graded, or contained a parking lot, roadway, or other structure.
75
What is the DEVELOPMENT FOOTPRINT?
The development footprint includes all areas of a site affected by the development or project site activity. Include hardscapes, parking lots, access roads, non-building facilities and the building itself.

30% (USGBC)
97
What is DRIP IRRIGATION?
Drip irrigation delivers water at low pressure through buried mains and sub mains. Water is distributed to the soil through a network of perforated tubes or emitters. Drip irrigation is much more efficient than traditional sprinkler systems.
98

They are an invasive species of plants that inhibit the cultivation and growth of local native or adaptive plants.
99
What are NATIVE or INDIGENOUS plants?
They are adapted to a given area during a defined time period and are not invasive. In North America, the term often refers to plants growing in a region prior to the time of settlement by people of European descent.
100
What are considered INVASIVE plants?
They are nonnative to the ecosystem and likely to cause harm once introduced. These species are characteristically adaptable and aggressive, have a high reproductive capacity, and tend to overrun the ecosystems they enter. Collectively, they are among the greatest threats to biodiversity and ecosystem stability.
