Q

Define NONPOINT SOURCE POLLUTION:

A

Where pollutants enter a river from multiple land uses that can’t be specifically identified.

19
Q

To reduce the quantity and improve the quality of rainwater runoff:

1 - Limit the number of _____ surfaces
2 - _____ rainwater
3 - Adopt some _____-_____ strategies

A

1 - impervious
2 - reuse
3 - low-impact

20
Q

What is LEED’s definition for an IMPERVIOUS SURFACE?

A

A surface having a prerviousness of less than 50%.

Less than 50% of the rainwater and/or surface water is absorbed into the ground

21
Q

List three methods of “low-impact development.”

1 - _____ _____ (or planted areas)
2 - _____ and vegetated _____ (includes running water through _____ or _____)
3 - _____ ponds (_____ ponds)

A

1 - Rain gardens (or planted areas)
2 - Bioswales and vegetated filters (includes running water through compost or rocks)
3 - Dry ponds (detention ponds)

22
Q

Define DRY POND (detention pond)

A

A basin whose outlets have been designed to detain rainwater runoff for some minimum time (e.g. 24 hours) while the rainwater slowly seeps into the ground or discharge . This allows pollutants to settle.

23
Q

Define WET POND (retention pond)

A

A pond designed to hold a specific amount of water indefinitely (reservoir)

24
Q

Define HEAT ISLAND EFFECT

A

a result created when developed areas have higher temperatures than surrounding rural areas.

25
Q

Identify three causes of heat island effect:

1 - _____ heating up _____ colored surfaces such as _____ and _____
2 - _____ streets and _____ buildings reducing air flow through the city
3 - vehicle _____

A

1 - sunlight heating up dark colored surfaces such as roads and rooftops
2 - narrow streets and tall buildings reducing the air flow through the city
3 - vehicle exhaust

26
Q

Identify seven strategies to reducing heat islands:

1 - Minimizing the _____ footprint
2 - Undercover/underground _____
3 - Using hardscape materials with high _____
4 - Installing surfaces that have a high solar _____ (SR) or high solar _____ index (SRI)
5 - Installing green _____
6 - Providing _____ from trees, structures covered by _____ _____, or architectural devices with high _____ material
7 - Using open-grid _____

A 
1 - development
2 - parking
3 - reflectance
4 - reflectance, reflectivity
5 - roofs
6 - shade, solar panels, SRI
7 - paving
27
Q

A

Roofing, reject

28
Q

The solar reflectance (SR) of an object is used for all _____-_____ materials to measure how a material will reject solar heat.

A

Non-roofing

29
Q

Define the “AGED VALUE” of a material’s SRI or SR:

A

How the material is going to perform years down the road. Materials get dirty; they get worn down, and perform less as time goes on.

30
Q

Solar reflectance measures a surface material’s ability to _____ sunlight on a scale of 0 to 1 with black paint having a solar reflectance of _____.

A

Reflect, 0

31
Q

What do you call the measurement of how much heat or infrared radiation a material is able to shed back into the atmosphere.

A

Emissivity

32
Q

The solar reflectance index (SRI) is a combined metric of which two factors?

A

Solar reflectance and emissivity

33
Q

Regarding SRI - the higher the number on a scale of 0 to 100, the _____.

A

Better

34
Q

Define FAR and explain how to calculate it.

A

Floor area ratio

The total building square footage (building area) divided by the site size square footage.

35
Q

“One of the objectives of green building is to build ‘_____’ rather than ‘_____’, thereby having a _____ building footprint to maximize _____ _____ and promote _____.”

A 
Up
Out
Smaller
Open space
Biodiversity
36
Q

Define EVAPOTRANSPIRATION

“Projects in dry climates want to use plants that have _____ evapotranspiration rates which require _____ water…”

A

An energy-absorbing process that actually cools the surrounding area.

Low
Less

37
Q

“For LEED, only pavement that is at least _____% pervious is allowed to be counted as _____-_____ pavement.”

A

50

Open-grid

38
Q

LEED uses the BUG method for _____ pollution reduction.

A

Light

39
Q

Define the BUG METHOD.

A

Backlight
Up light
Glare

(Used to reduce light pollution)

40
Q

Identify three methods to prevent light pollution:

1 - Lighting _____
2 - Lighting _____
3 - Light _____ and _____

A

1 - design - uses the BUG method
2 - controls - such as automatic light shut offs
3 - fixtures, placement (such as full cutoff, fully shielded, and partially shielded lamps that help direct light down and prevent it from escaping from a project site)

41
Q

Define IESNA

A

Illuminating Engineering Society of North America

42
Q

Define LIGHT TRESPASS

A

Where light escapes the project and goes beyond the project border. (Horizontally and/or vertically)

43
Q

LEED considers _____ and other unwanted _____ to be pests.
