Ecological Compensation

Our systems for optimum green roofs are an important contribution to climate compensation. As a recognised measure of the impact compensation regulation under nature protection law, green roofs offer new living spaces for people, plants and animals. The large storage capacity and evaporation of precipitation on the roof relieve pressure on the sewer system, especially in the event of heavy rainfall. At the same time, the green roof efficiently cools both the surrounding area and the building and also contributes to air humidification and fine dust filtration. As protection against extreme t...

Understanding Blue Roofs - From design to application
Increases in our urban population, the density of urban development and the effects of climate change are all placing additional pressure on our public surface water drainage systems.
Designed and installed correctly a blue roof can provide a very successful surface water management solution for modern construction projects. This CPD session covers topics such as the principles of a blue roof, the benefits it can provide and the importance of the specification process.

This article will explore blue roofs and their application. 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 CPD will look at how this can be achieved practically and why this type of specification is likely to become more commonplace in the future. By the end of the article you should have a greater understanding of:
- What a blue roof is
- Why and when they need to be specified
- How to provide accurate calculations for a successful blue roof specification
- The components that make up a blue roof system
