A Case Study Comparison
Reduces water use by 30% compared to a building with standard code-compliant fixtures
Uses 51,300 kBtu/ft2 of energy annually, a 39% reduction from base case
Reduces carbon emissions by 19 lbs CO2/ft2, or 50% by purchasing renewable energy.
Provides daylight for 75% of regularly occupied spaces and views for 90% of occupied work areas
Landscape Performance SeriesSlide 6
A Case Study Comparison
Stormwater planters
10 new trees
Native and adapted plants
Permeable pavers
5 new seating areas
Local stone
FSC-certified wood
Landscape Performance SeriesSlide 7
A Case Study Comparison
Captures and cleans stormwater runoff
Reduces the urban heat island effect
Sequesters carbon
Reduces potable water use
Cleans the air
Increases social value of space
Landscape Performance SeriesSlide 8
From Features to Claims to Benefits
Reduces stormwater runoffCaptures and infiltrates 30% of all rain falling on the site.
Sequesters carbonTraps 1,500 lbs of carbon annually in tree biomass.
Increases social value of spaceIncreased café patronage by 30% on weekdays and 50% on weekends.

Landscape Performance Series
a collection of resources designed to make “landscape performance” as well
understood as “building performance” NOT a rating system focused on built, performing projects generating demand for sustainable landscape solutions a resource that will grow over time and with your

Quantifying Benefits
Determine from design parameters Stormwater modeling, area calculations, etc. Rating system submittals (LEED, SITES)
Gather additional information Use public information (property tax, GIS data) Contact other project stakeholders
Estimate using rules of thumb Use online calculators and tools Obtain actual measurements/monitoring data Combine Methods
