Top Considerations for Vegetated / Green Roof Designs
WEDNESDAY, DECEMBER 6, 2017
There is no shortage of benefits to installing a vegetated roof, from both an environmental perspective as well as a financial one. A vegetated roof (VR) can provide access to green spaces in concrete jungles, they mitigate heat, and they can provide increased energy efficiencies. In addition, many municipalities and programs are now offering financial incentives for their installation.
That said, today’s VR assemblies are as varied as the buildings they are installed on, and there are a number of factors architectural design teams, building owners and facility managers need to consider in their selection or assembly specification.
Whether working with difficult weight and budget limitations, or trying to achieve maximum storm water retention capacity and cooling benefits, any design team needs to consider the following factors:
Weight / structural limitations
Cost – both upfront and recurring
System component compatibility
Storm water retention capacity
Design versatility and / or customization
Built-in-place vs. modular construction
Desired plantings: sedum, grasses, wildflowers, perennials, shrubs, trees
Extensive / intensive applications
Roof slope & roof accessibility
Climate / temperature during installation
Damp or green concrete application
LEED certification availability
With the proper design, installation and maintenance schedule, a vegetated roof system can fulfill all its intended environmental and financial impacts. By carefully taking all these considerations into account — and planning accordingly — you can ensure the success of your assembly.
