GREEN & BLUE INFRASTRUCTURE
neighbouring properties, below ground attenuation had to be kept to a minimum, leaving the roofs and high level podiums as the key attenuation strategy. Radmat’ s Blue Roof System had to be redesigned a number of times to meet the stringent attenuation targets, even utilising the‘ fingers’ of the roof to maximise the available space.
Because the development had to meet high thermal standards and provide as much amenity space to residents as possible while at the same time providing extensive attenuation – the system build ups were considerable and therefore design heights at thresholds and parapets were compromised in some areas.
A series of inverted PermaQuik Hot Melt Blue Roofs were specified to provide a robust waterproofing and were supported by BBA certification for both blue roofing applications and an independent durability statement for the design life of the building. In the most challenging areas Radmat proposed its ProTherm Quantum Vacuum Insulated Panel system which enabled the area to meet the thermal requirement in 80 % less space compared to standard insulants, while still meeting the attenuation demands.
Finished with Radmat’ s MedO Green Roof systems – both fully vegetated blankets for areas overlooked by apartments and seeded biodiverse roofs surrounding the PV panels – the roofs also incorporated ecological requirements for biodiversity with different growing medium formulations and planting incorporated on different roofs. These habitat roofs have been included to promote environments that will support bees, butterflies and birds.
