Sustainable Sites

Question 1

Heat island effect

Answer 1

Increased temperature from impervious surface, reduced airflow, vehicle exhaust, AC

Question 2

Integrated pest management IPM

Answer 2

Native landscaping helps

Question 3

Green roof

Answer 3

Lower HVAC cooling costs, rainwater management

Question 4

Sedimentation

Answer 4

From run off, pollutants and particulates in water

Question 5

Solar reflectance index Sri (for roofs)

Answer 5

High is reflective, low is bad, range 0-100, need reflectance - white roof is 100

Question 6

Eutrophication

Answer 6

Too much nutrients

Question 7

Sustainable sites

Answer 7

Restoration, bio diversity, ecosystem integration

Question 8

60% of eco system services

Answer 8

Are degraded or used unsustainably

Question 9

Emissivity

Answer 9

Ratio of energy radiated to energy from black body same temp

Question 10

Erosion and sedimentation control plan ESC

Answer 10

Construction pollution prevention made by civil engineers, follow EPA construction General permit guide

Question 11

Site assessment

Answer 11

Hydrology and geology included, also topography, climate, vegetation, soils, human use and human health, synergies with other credits

Question 12

3 year aged sr value

Answer 12

How much it reflects after 3 years

Low impact development

Answer 13

Water runoff management technique emphasizes on site natural features

Question 14

project boundary

Answer 14

boundary submitted for LEED certification
