While green roofs are designed to be sustainable features in the urban landscape it takes a little ingenuity a bit of imagination and a lot of product and plant knowledge to make the whole project come together.
Green roof irrigation requirement.
Designing green roof irrigation.
For green roofs that receive runoff from roof directly connected impervious area dcia inlet control systems may convey and control the flow of stormwater from the contributing catchment area to the green roof.
Optimizes distribution of rain irrigation water across the roof surface even on steeply pitched roofs.
Planning for irrigation on a green roof should consider the site layout and conditions access exposure type of plants climate and water supply issues pressure quality etc.
Green roofs that receive direct 1 1 rainfall only do not have inlet controls.
Enables the vegetal i d.
Consider irrigation of intensive green roof systems early none of the above removes the requirement for good sound horticultural practice such as weeding seasonal mulching thinning out the plantings appropriate feeding or installing the plants at a size that enables them to slowly acclimatise to their new environment.
We suggest on an extensive sedum green roofs a permanent irrigation system is not necessary but consideration must be paid to the roof and supplementary watering if periods of prolonged drought 2 weeks occur.
A truly environmentally friendly solution.
Substrate properties and depth are also important as they influence water infiltration holding capacity and drainage.
For extensive green roofs that require occasional watering.
