Designing flat roofs for sustainability

2 mins

As urban expansion continues to absorb natural habitats, landscaping a flat roof can act as practical use of space providing fresh areas to replace lost habitats and encourage the local ecology to thrive.

Bauder Designing for rooftop sustainability
BAUDER introduced green roof technology to the UK and Ireland over 30 years ago and provides a service to match the vast experience of delivering green roof projects.
Soft landscaping can also help reduce the risk of flooding by retaining proportions of rainfall and decreasing rainwater run-off rates. The BauderBLUE roof system is designed to attenuate and manage stormwater on a flat roof. These types of rooftop solutions are part of the CIRIA sustainable drainage systems (SuDS) design guide. The engineered outlet within a blue roof restricts the discharge of storm water to a calculated and pre-designed flow rate to significantly slow down the volume of water leaving the site.

They prove beneficial in built-up areas where there are large amounts of impervious surfaces. Bauder green roofs retain rainwater in the substrate, drainage board and plants. The water absorbed by the vegetation evaporates back into the atmosphere.

Thorough planning is required during the installation of blue and green roofs as adequate time is needed for the crane to lift products to the roof, ensuring the placement doesn’t overload the building’s structure.

The vegetation should be delivered on the day of installation, with quantities matching those to be installed on that working day. A collaborative approach will achieve the best results.
