| Stormwater Compliance |
Annual Water Retention |
50% to 90% of annual rainfall. |
Exceeds DMV Mandates: The deeper media ensures high water capacity, significantly reducing overall runoff volume and controlling peak flow, critical for local compliance. |
| Peak Flow Reduction |
Reduces peak flow rate by 50% to 90% and provides substantial discharge delay. |
Mitigates Flood Risk: Protects public infrastructure and helps the client avoid costly stormwater utility fees and non-compliance fines. |
| Thermal Performance |
Roof Surface Temp. Reduction |
Roof surface remains up to (6)° cooler than conventional roofs. |
Extends Asset Life: Eliminates thermal shock and UV exposure, potentially doubling or tripling the life of the underlying membrane. |
| Building Cooling Load |
Reduces heat transfer through the roof by up to 95% in summer. |
Optimizes Energy Costs: Provides superior insulation (higher R-Value) for significant year-round energy cost savings and HVAC efficiency. |
| Structural / Installation |
Saturated Weight |
35–45 lbs/ft2 (varies by media and components). |
Feasible Retrofit: The modular design and mid-range weight allow installation on many existing commercial structures without major structural modifications. |
| Installation Process |
Pre-grown, modular trays simplify logistics and accelerate on-site installation time. |
Management Efficiency: Allows for fast, single-source installation oversight, reducing labor costs and project scheduling conflicts. |
| Ecological / Aesthetic |
Plant Diversity & Health |
Supports a wide palette of plants (sedums, grasses, herbs) that are highly resilient. |
Guaranteed Coverage: Ensures necessary GAR (Green Area Ratio) requirements are met with a visually rich, self-sustaining, and low-maintenance landscape. |
| Integrated Potential |
Ideal depth for Biosolar integration (PV panels). |
Future-Proofing: Provides the perfect balance of media depth and structural support to integrate solar panel systems, maximizing PV efficiency through ambient cooling. |
