Question 1

Floor area ratio (FAR)

Answer 1

The density of non-residential land use, exclusive of structured parking, measured as the total non-residential building floor area divided by the total buildable land area available for non-residential structures

Question 2

Smart growth

Answer 2

An approach that protects open space and farmland by emphasizing development with houses, jobs and services near each other

Question 3

Shortest path analysis

Answer 3

A measurement of how far a pedestrian and bicyclist would travel from a point of origin to a destination, reflecting access to amenities, safety, convenience and obstructions to movement

Question 4

Density calculation

Answer 4

For this category, density is a measure of the total building floor area or dwelling units on a parcel of land relative to the buildable land of that parcel (higher density location means more people will live near the project)

Question 5

Low impact development (LID)

Answer 5

A land management strategy that emulates natural systems to manage rainwater as close to its source as possible

Question 6

Nonpoint source pollution

Answer 6

Water pollution caused by pollutants, such as gasoline, oil, salt and fertilizers, which are washed into the nearest water bodies by rainwater runoff

Question 7

Solar reflectance index (SRI)

Answer 7

A metric from 0 to 100 that measures how well a material reflects solar heat, with higher numbers signifying better reflectance

Question 8

Xeriscaping

Answer 8

Landscaping designed to reduce or eliminate potable water use in irrigation through the planting of native and adapted species of vegetation and the use of other water-conserving techniques

Question 9

Water balance approach

Answer 9

Bases projected water usage on the annual amount of rainfall

Question 10

Efficiency first approach

Answer 10

Reduce water use, then consider alternative water sources such as rainwater collection, water reclamation and on-site treatment to tertiary standards

Question 11

How is water usage measured for water closets and urinals?

Answer 11

Gallons per flush (gpf)

Question 12

How is water usage measured for faucets and showers?

Answer 12

Gallons per minute (gpm)

Question 13

How is water usage measured for industrial uses?

Toilets and urinals

Question 15

Provide three examples of flow fixtures

Answer 15

Faucets, hoses and dishwashers

Question 16

Design case

Answer 16

The actual project design metrics that are compared to a baseline to show efficiency gains

Question 17

Drip irrigation

Answer 17

Water delivered at a low pressure directly to the roots of a plant

Question 18

Energy use intensity (EUI)

Answer 18

A metric that expresses a building’s energy use as a function of its size

Question 19

Illuminating Engineer society of North America (IESNA)

Answer 19

An organization that publishes nationally and internationally used standards for the lighting industry

Question 20

Lighting power density (LPD)

Answer 20

The installed lighting power per unit area

Question 21

Answer 21

Treaty banning the use of CFCs and phasing out the use of HCFCs

Question 22

GreenScreen

Answer 22

A hazard assessment method that evaluates individual chemicals
