Sustainable Sites Flashcards
What is albedo?
a metric to define the reflectivity of an object from darkest black to white using a scale from 0 to 1
What is building footprint?
the area of ground hat the building occupies as defined by its perimeter
What is GI? What does it stand for?
Green infrastructure: the patchwork of natural areas that provide habitat, flood protection, clean air, and clean water at the scale of a city or county, or rainwater management systems that mimic nature by soaking up and storing water at the scale of a neighborhood or site
What is IPM? What does it stand for?
Integrated pest management: a sustainable approach of controlling pest infestation and damage in an economical way while minimizing hazards to people, property, and the environment
What is light trespass?
the spillage of light across a project boundary onto neighboring sites
What is LID? What does it stand for?
Low impact development: a land management strategy that emulates natural systems to mange rainwater as close to its source as possible
What is SRI? What does it stand for?
Solar reflectance index: a metric from 0 to 100 that measures how well a material reflects solar heat, with higher numbers signifying better reflectance
What is watershed?
the area of land where all the water that is under it or drains off of it goes to the same place
What are the types of strategies for the sustainable site category?
Site design and management strategies
Rainwater management strategies
Heat Island strategies
Light pollution strategies
What are the site design and management strategies?
Prevent construction pollution Protect and restore habitat Reduce size of building footprint Increase site density Maximize open space Plant native and adapted species Develop sustainable site management plan
What are the rainwater management strategies?
Reduce impervious hardscape
Implement rainwater management
Use passive rainwater management
Use active rainwater management (rain barrels, water cistern)
What are the heat island strategies?
Reduce exposed hardscapes
Use high-reflectance materials
What are light pollution strategies?
Install motion sensors and timers
Eliminate unnecessary lighting
What are the 3 forms of light pollution? What is BUG?
Upplight (causes artificial sky glow)
Glare (caused by high-angled front lighting)
Light trespass (is backlight caused by misdirecting light onto adjacent sites and in the opposite direction of the area intended to be lighted)
BUG: (backlight, upplight, glare)rating method classifies luminaries according to their potential to generate light pollution
How much water does flushing toilets use?
30% of treated domestic water
