Blue Roof Water Retention

Not only do they detain water but blue green roofs also reduce the stormwater volume using plants.

Blue roof water retention.

A blue roof may be used as a stand alone detention method or because they do little to improve the water quality of runoff as part of a treatment train that includes other low impact development and conventional best management practices bmps such as bioretention infiltration wetland systems or green roofs to enhance the function improve. Blue green roofs are superb. The permanently water saturated load is divided by sixpercentage of empty space. The secret of green roof water retention is green.

Blue roofs also known as controlled flow roof drain systems are detention stormwater management practices smps that provide temporary storage and slow release of rainwater on a rooftop. A blue roof is a roof designed for the retention of rainwater above the waterproofing element of the roof. This retained water never becomes runoff it simply leaves the roof as vapor. Blue roof technology however aims to increase both the volume of water stored and control the amount of water released.

It is also known as fluid retention or edema. Water retention occurs when excess fluids build up inside your body. This means that the water leaves the roof as vapor. Blue roof sustainable drainage solution rooftop suds.

The blue green roof combines blue and green roof technologies. Retention works like this. Blue roofs are typically flat without any fall with control devices regulate drainage outlets that enable water to be retained or drained. A bauderblue roof is designed specifically for each individual project.

Blue roof systems are an effective practice for controlling runoff from buildings with flat or mildly sloped roof surfaces. 95 of empty space. Conventional green roofs conventional use a drainage layer to provide lateral drainage and irrigation. The combined evaporation and transpiration processes or evapotranspiration adds retention to the roof.

This is as opposed to more conventional roofs which allow for rainwater to drain from the roof. Water retention occurs in the circulatory system or within tissues and cavities. A blue roof slows or stores storm water runoff but it accomplishes this by using various kinds of flow controls that regulate block or store water. On top of this blue green roofs add detention.

Rain falls onto a relatively dry green roof and the green roof absorbs the water usually in pore spaces later the sun comes out and the plants use the rainwater to evapotranspire. Direct groundwater recharge via methods like downspout. Improvements to roof patios accessible high tech garden car park etc at an equivalent height of retention the volume of water stored is multiplied threefold.
