Changes in the way we receive rainfall in the UK because of climate change has led to rainwater management around buildings becoming a key consideration as part of the design process. Green roofs are already known for their ability to attenuate water, but this can now be enhanced with blue roof technology. Here the roof not only stores water but is also able to delay water discharge after a high intensity rainfall event and release it at a pre-determined rate. This topic will look at how this can be achieved practically and why this type of specification is likely to become more commonplace in the future.
During this session delegate will learn:
1. How blue roofs can help manage rainfall runoff
2. How a blue roof is constructed
3. How they are used in practice
4. Specifying a blue roof
5. Blue roof project case study
