The University of Bristol

The University of Bristol commissioned the construction of a brand new 450 seat lecture theatre for its Faculty of Social Sciences & Law. It was a planning stipulation that there should be no increase in the amount of excess water discharged into the existing drain infrastructure, therefore a Blue Roof solution, combined with a Bio-Diverse Green Roof was specified to meet this condition. Alumasc developed a BluRoof specification to provide the stormwater attenuation performance required to obtain planning approval from a drainage perspective. The solution was also able to ensure that the attenuation measures were not visible; being concealed by a bio-diverse green roof, designed, supplied and installed by Blackdown.
