When used with control flow drains roofblue expands the usefulness of a green roof system as a stormwater management tool.
Roof detention system.
For a detention facility where the outflow is controlled by means of an outlet orifice tube subject to a head which increases as the depth of storage increases in a storage facility with an approximately uniform area with respect to storage height and for roof detention by means of.
Blue roofs are non vegetated source controls that detain stormwater either releasing it more gradually to the sewer system or storing it for beneficial reuse.
Over 500 different tests were carried out on various green roof structures commissioned by independent international partners from the construction industry.
Purple roof is the simplest and least expensive solution if you would like a detention green roof.
It is made of a filtration veil and the polyamide monofilament fibre network layer.
Reduce the burden on stormwater systems.
All kinds of rainfall can be simulated in this lab.
Bauder sdf drainage layer one side laminated version is also avaliable.
Rooftop detention is the heart of blue roof technology.
Almost all of the rain that falls onto a fully saturated profile will quickly drain through and flow underneath a traditional green roof profile.
Instead of running off the roof via gutters and downpipes the water is temporarily stored or allowed to pond on the surface and then released slowly so that it can drain away gradually.
It has been evaluated and tested by green roof diagnostics.
Rooftop detention also known as a blue roof is designed to provide temporary storage and slow release of stormwater runoff.
A standard sponge roof can be upgraded from a retention oriented green roof to a detention retention oriented green roof for 10 20 m 2 1 2 sqft.
The goal of a detention oriented green roof is to delay peak runoff so that sewage systems have time to drain.
Protection drainage and filtration.
This roof can then detain 2 5 5cm 1 2 of water for anywhere between 1 10 hours.
It is a relatively simple concept that results in a controlled flow system of rainwater from the roof.
Roofblue can do the following.
Urbanscape detention layer t5.
Thus detention has a time component added.
The liveroof integrated roofblue riser is engineered to provide temporary water detention underneath all liveroof systems.
The foundation of the detention roof lies in the green roof diagnostics research laboratory in virginia usa.
It is used for lightweight green roofs terraces and has many functions.
