5. Landscape Performance Series Slide 5 A Case Study Comparison Reduces water use by 30% compared to a building with standard code-compliant fixtures Uses 51,300 kBtu/ft 2 of energy annually, a 39% reduction from base case Reduces carbon emissions by 19 lbs CO 2 /ft 2, or 50% by purchasing renewable energy. Provides daylight for 75% of regularly occupied spaces and views for 90% of occupied work areas

6. Landscape Performance Series Slide 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

7. Landscape Performance Series Slide 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

8. Landscape Performance Series Slide 8 From Features to Claims to Benefits Reduces stormwater runoff Captures and infiltrates 30% of all rain falling on the site. Sequesters carbon Traps 1,500 lbs of carbon annually in tree biomass. Increases social value of space Increased café patronage by 30% on weekdays and 50% on weekends.
