LEED & TGS v4 Compliant
LEED & TGS v4 Compliant
- Meets TGS WQ 1.3 On-Site Green Infrastructure as a biodiverse green roof
- Uses natives listed in the Design Guidelines for Biodiverse Green Roofs
- Use of native plants meets LEED SS Credit: Protect or Restore Habitat
Low Maintenance
Low Maintenance
- Ontario native plants that are specially selected to thrive on rooftops
- Pre-grown natives are heat & drought tolerant with low nutrient needs
- Perennials come back year after year, also propagate by seeds
High Performance
High Performance
- Engineered growing medium is formulated for longevity and vitality
- 7mm initial abstraction for water balance calculation per Toronto Water
- Supports grey water reuse onsite via automatic irrigation systems
Supports Biodiversity
The Alpine Meadow brings nature back to the urban core with native hardy plants – pre-grown in a blanket. Instant green upon installation, it is a pollinator’s haven providing nourishing pollen and nectar, as well as nesting habitats. The Alpine Meadow meets TGSv4 WQ 1.3 2. Intensive Green Roof and 3. Biodiverse Green Roof.
Manages Stormwater
Meets TGSv4 1. Water Balance. Stormwater retention can be increased with the Hydro Blanket or recycled polymeric water retention layers that are lighter in weight and hold more rainfall compared to traditional growing medium.
