2. LEED Building Credits 6-14 credits for GR
(White Roof receives 1-2 credits)
Provides Year Round Energy Savings
Improves Air Quality
Extends Life of Roof Membrane
Increases Aesthetics: Rents go up!
Biggest Drivers: cities implement policy
Reduces Heat-Island Effect
Stormwater Management
AVRS ® Patented

3.  Increased peak flows
• Accelerated erosion
• Habitat degradation
 Increased runoff volume: flooding

4. Pre-Settlement Historical Urban Urban Green
Conditions
Development

7.  97% mean runoff rate
reduction. (88%, 93% others)
 54% runoff volume reduction
(-10%, 67% others)

8. 1. Managing the Storm Water- 2. Streamlined Install / Long Term
The
Maintenance
Skyscape® Tray and the drainage holes in the
troughs and on the ridges are mathematically
designed to detain and meter the stormwater.  Ease of Installation: Goof Proof
 Assembled AVRS® trays with fitted irrigation lines
The Skyscape Multi-layer: Retention Mat

9.  The drainage holes in the troughs
and on the ridges are engineered
to detain and meter the
stormwater.
 Given an instantaneous 1”
rainstorm the SkyScape tray would
meter and slow down the rainfall
by 3.5 minutes.
 A SkyScape tray filled with growing
media and plants would retain
70% of this stormwater.
 A SkyScape tray with media and
plants will filter and remediate the
stormwater before runoff.

10.  The SkyScape trays overlap and pin
together creating a fully
encapsulated roof area
 5% angle on all sides allows trays to
freely articulate over crickets and
down through depressions with out
separating.
 Engineered Stormwater
Management
 A SkyScape tray with media and
plants will filter and remediate the
stormwater before runoff.

11.  Engineered overlapping
and interlocking trays
insure proper registration
so that tray area remains
square.
 Integral drip irrigation
system; affixed to tray with
hook system.

13. Install Process
Trays: pallets Multi-layer: arrives in rolls

14. Trays: lay trays on membrane and lock Multi-layer: roll out layers: drainage,
together. filter then retention layer

16. Hybrid System – install in areas the tray won’t
fit or weight issues

17.  Specifically designed to fit tray
 Pinned to make a lasting
connection
 Hides tray edges from exposure
and allows tray to be over filled.
 Comes in both Aluminum and
Stainless Steel.

20.  Various Species Available
 Spring or Fall Install Only
 High in Maintenance and
Establishment
 Irrigation Required
 Fast install
 Preferred application is
250lbs./1000sf.

21.  Various Species
 Year Round Install,
preferably fall or spring.
 Establishment required
 Harder and more time
consuming to install.
 Typical Application
(8”oc-72cell)

22.  Immediate Full
Coverage
 Limit standard species
selection
 Limited establishment
time
 Less Maintenance
 Fast Install

23.  Immediate full
coverage
 Limited establishment
time
 Slow Install time, do
to weight.

25. Portland State Research has shown that…
Due to the cooling effect of the Eco-Roof
the Solar Modules work at higher
efficiencies. Studies show 1-3% better
efficiencies.
