2. LT & SS

Question 1

Integrated Process Credit

Answer 1

Look for synergies by having a charette and performing:
Simple box energy modeling
Water budget analysis

Question 2

Previously Developed Site

Answer 2

Altered by paving, construction, and/or grading. If there is a building or hardscape on the site, it is previously developed. If site EVER had a building, it is previously developed.
Ideally, develop these sites again.

Question 3

Previously Disturbed Site

Answer 3

Includes previously developed sites
Also includes sites that have been compacted, cleared, or disturbed in any way. Not a greenfield site.

Question 4

Greenfield Site

Answer 4

Sites not previously developed
Do not want to develop these sites, they should be protected to keep native / adapted plants on site / open habitat

Question 5

Brownfield Site

Answer 5

A previously developed site that has environmental contamination

Question 6

Infill Location

Answer 6

A site where at least 75% of the land area, exclusive of rights-of-way (i.e. streets), within ½ mile of the project boundary is previously developed.

Question 7

ACEEE / American Council for an Energy Efficient Economy

Answer 7

Referenced Standard for Green Vehicles

Question 8

25% & 33%

Answer 8

Transportation accounts for 25% of GHG emissions globally
Transportation accounts for 33% of GHG emissions in the U.S.

Question 9

BUG Rating Method

Answer 9

A luminaire classification system that classifies luminaires in terms of backlight (B), uplight (U) and glare (G). Referenced Standard for Light Pollution Reduction.

Question 10

Compact Development Strategies

Answer 10

Build up, not out. Limit culs-de-sac, prohibit gated communities, use a street grid pattern/high street grid density. Mixed use, mixed income, connected to surrounding services.

Question 11

Boundaries

Answer 11

LEED Boundary – entire construction site or property, set by the project team
Building Footprint – area the building sits on
Development Footprint – all of the total land area covered by buildings, streets, parking areas, and other typically impermeable surfaces

Question 12

Evapotranspiration

Answer 12

A cooling benefit from plants (evaporation and plant transpiration into the atmosphere), and why plants are best on the site and on the roof (“free cooling” feature).

Question 13

Heat Island Effect

Answer 13

The thermal absorption by hardscape, such as dark, nonreflective pavement and buildings, and its subsequent radiation to surrounding areas. Other contributing factors may include vehicle exhaust, air-conditioners, and street equipment. Tall buildings and narrow streets reduce airflow and exacerbate the effect.

Question 14

Solar Reflectance Index (SRI)

Answer 14

A measure of the constructed surface’s ability to stay cool in the sun by reflecting solar radiation and emitting thermal radiation. To calculate the SRI for a given material, obtain its solar reflectance and thermal emittance

Question 15

Solar Reflectance / Albedo

Answer 15

The fraction of solar energy that is reflected by a surface on a scale of 0 to 1. High reflectance is desired.

Question 16

Thermal emittance

Answer 16

The ratio of the radiant heat flux emitted by a specimen to that emitted by a blackbody radiator at the same temperature

Question 17

Erosion & Sedimentation Control

Answer 17

Seeding / Mulching
Earth Dikes
Silt Fences
Sediment Traps
Sediment Basins

Question 18

Water Balance

Answer 18

Determining the amount of water that falls on a site from precipitation and implementing project needs accordingly

Question 19

Biodiversity

Answer 19

The diversity, or variety, of plants and animals and other living things in a particular area or region. Critical for human (and all) life.

Question 20

Native Vegetation

Answer 20

Indigenous species that occur in a particular region, ecosystem, and habitat without direct or indirect human actions. Provide habitat, save water, reduce maintenance, do not need chemicals.

Question 21

Adapted Plants

Answer 21

Vegetation that is not native to a particular region, but that has characteristics that allow it to live in the area. Adapted plants and encouraged, second to native plants.

Question 22

Invasive Plants / Species

Answer 22

Non-native vegetation that has been introduced to an area and that aggressively adapts and reproduces. The plant’s vigor combined with a lack of natural enemies often leads to outbreak populations

Question 23

Low-Impact Development (LID)

Answer 23

A stormwater development strategy designed to mimic the site’s pre-development rainwater management. These are low-cost, on-site features to allow rain-water to infiltrate, filter, store, evaporate, and detain runoff. i.e. pervious pavement, open space, rain gardens.

Question 24

Green Infrastructure

Answer 24

A soil- and vegetation-based approach to rainwater management that is cost-effective, sustainable, and environmentally friendly. Bioswales, rain gardens, green roofs, and open space.

Question 25

Light Pollution

Answer 25

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 safety, utility, or security and needlessly consumes energy.

Question 26

Light Trespass

Answer 26

Obtrusive illumination that is unwanted because of quantitative, directional, or spectral attributes. Light trespass can cause annoyance, discomfort, distraction, or loss of visibility.
