Q

Define a development footprint Vs Building Footprint

A
  • Includes all areas that will be affected by the project’s activity. It includes the building, access roads, parking lots, sidewalks, other hardscapes, and any other type of building like a storage shed, etc.
  • Area covered by the building structure but does not include parking lots, landscaped areas, etc.

Q

Define Open Space

A

the area that is both vegetated and pervious.
are usually defined by local zoning requirements; else, LEED defines it as the area of the property minus the development footprint.

Q

Strategies to reduce impervious surfaces

A

having smaller footprints and more open space.
create strips of vegetation that are low enough to capture rainwater
open grid paving

22
Q

Strategies to manage Rainwater

A

Rain gardens, or planted areas
Bioswales and vegetated filters
Dry ponds

23
Q

whats an ESC plan ?

A

Stabilization & Structural Methods

24
Q

Heat island definition

A

temperature differences between developed and undeveloped areas

25
Q

Urban heat islands definition

A

10 degrees in developed areas compared to more rural surroundings

26
Q

health problems associated to heat isand effect

A

heat island effect derives to more ground level ozone and more smog. Therefore problems related to air quality

27
Q

heat islands effects over rainfall

A

rainfall downwind of major urban areas can be as much as 20%

28
Q

strategies to reducing heat islands

A

Minimizing the development footprint
Undercover / underground parking
Using open-grid paving
Installing surfaces that have a high solar reflectance (SR) or solar reflectivity index (SRI)
Using hardscape materials with high reflectance
Installing green roofs
Providing shade from trees, structures covered by solar panels, or architectural devices with high SRI material

29
Q

Explain Solar Reflectance

A

ability to reflect sunlight (0 to 1)

black paint having a SR of 0, and white paint having a SR of 1

30
Q

Explain (thermal) Emissivity

A

materials ability to release absorbed heat (0 to 1)

unpainted cement tiles (0) - white coated tile (1)

31
Q

SRI (solar reflectance index)

A

The combination of both solar reflectance and thermal emittance

32
Q

Key strategy to reduce the heat island effect

A

minimize the development footprint

33
Q

Whats the floor area ratio (FAR)

A

total building square footage / the site size square footage (no sidewalks nor easements included)
Ex. A 4 story building is built on 1/2 the lot. This is a FAR of 2.0

34
Q

Benefits of Green Roofing

A

By absorbing rainwater, they reduce runoff
provide insulation
acoustic dampening
combat the heat island effect

35
Q

define Evapotranspiration

A

transpiration is how plants transfer water outside and evaporation as this being transfered to the air. is an energy-absorbing process, so it actually cools the surrounding area

36
Q

Strategies to reduce heat island effect from roads

A

cool pavements
open grid pavements
tree / solar panel shading

37
Q

Lightning pollution reduction strategies

A

Automatic light shut offs

Lightning design using the backlight, uplight, glare (BUG) method

38
Q

Building management pollution reduction strategies

A 
non-toxic snow and ice removal products
non-toxic cleaning chemicals
Low fertilizer levels
quiet and efficient equipment 
integrated pest management plan (animals and plants)
39
Q

What percentage of the ecosystem services that have been assessed worldwide are currently degraded or used unsustainably

A

60%

40
Q

the intent and goals of rainwater management?

A

Replicate the natural hydrology and water balance of the site

41
Q

the intent of protecting and restoring habitat?

A

Provide habitat and promote biodiversity

42
Q

the intent of construction activity pollution prevention

A

Control soil erosion from construction activities

43
Q

the intent of an environmental site assessment

A

Assess the site for environmental contamination

44
Q

Whats Eutrophication

A

The consequence of increased rainwater runoff.
It is the ecosystem response to the addition of artificial or natural substances, such as nitrates and phosphates from fertilizers or sewage, to an aquatic system.

45
Q

What is IESNA

A

Illuminating Engineering Society of North America. lighting design and illumination standards.

46
Q

Causes of the heat island effect

A
  • Dark surfaces that absorb heat
  • vehicle exhaust
  • air-conditioners
  • reduced airflow from tall buildings and narrow streets
47
Q

Heat islands impact what LEED category(s)?

A 
Sustainable Sites (SS)
Energy and Atmosphere (EA).
48
Q

STRATEGIES employed to reduce the HEAT-ISLANDS?

A

using materials with high SRI
shaded areas
reduce hardscape surfaces
installing vegetated roofs.

49
Q

Examples of impervious surfaces

A

Parking lots, roads, sidewalks, and plazas.

50
Q

Strategies to reduce potable water for irrigation?

A
  • Use gray water or rainwater for watering
  • Use drip irrigation
  • Install native and adaptive plants
