GREEN & BLUE INFRASTRUCTURE
ACO ’ s Blue Green roof construction
Neill Robinson-Welsh at ACO Building Drainage , said : “ If insufficient consideration is given to the drainage design , particularly for exceedance events , then the building integrity can be compromised by flooding . Blue Roof systems that utilise a single roof waterproofing have to trade off increased risk with a compromised flat roof drainage design .”
“ It is recommended that attenuation is considered at the earliest stages of the design , where architects , engineers and contractors collaborate with drainage specialists .
Installing RoofBloxx
This will allow project leads to find ways in which the roofing design is not compromised while meeting wider sustainable drainage system ( SuDS ) requirements .”
To overcome the challenge , ACO ’ s RoofBloxx blue roof attenuation system enables engineers to design to the correct standards , while meeting planning conditions without the need to compromise . The ACO RoofBloxx system is compatible with standard civils hydraulics , while it also allows inverted roof designs to be achieved without a reduction in U-values and
can be incorporated into any roof build up whether warm or inverted , new build or retrofit .
Neill added : “ The unique drainage requirements of blue / green roofs – coupled with the need to form part of a wider SuDS scheme – means that the initial hydraulic design of rainwater attenuation systems should include drainage specialists . Given the expected influx of blue / green roof requirements across metropolitan cities , collaborating at the earliest opportunity is critical for the smooth delivery of roof attenuation projects .”
To support professionals working on a blue / green roof , ACO has a free on-demand webinar which supports those working on a project . To register and watch the webinar , please visit www . aco . co . uk / 2021-webinar-series .
