Want to learn more about vegetated roof detention and retention research? We met with Dr. Anna Zakrisson from the green roof laboratory of Green Roof Diagnostics in Culpeper, Virginia. Short version. Full interview: https://youtu.be/qot1KpJIjPc Green Roof Diagnostics: https://www.greenroofdiagnostics.com Dr. Anna Zakrisson, was interviewed for Purple-Roof by Folkert Tempelman from Studio Piso7. These are the latest advancements in green infrastructure stormwater management. Zakrisson is part of a team of green roof researchers investigating and improving green roofs. Their main focus so far has been stormwater management. Detention green roofs can reduce or replace grey infrastructure stormwater management solutions such as tanks and cisterns. _____ Green & Grey Stormwater Management Options https://www.purple-roof.com/post/what-stormwater-management-options-are-there How to Manage Stormwater with Green Infrastructure https://www.purple-roof.com/post/green-infrastructure-stormwater-management _____ Feel free to embed these videos on your website.

We met with water resilience expert Nanco Dolman in Amsterdam. Nanco Dolman is a leading professional in Water Resilient Cities at Royal HaskoningDHV and has long experience in both disaster water management, for example storm Sandy, as well as in preventative measures. Nanco shares with us a very interesting perspective and some visions of how our future cities could look like and function with regard to water management. The main message is to see water as a resource and work *with it* and not against it.

We interviewed Dr. Helen Toxopeus, a researcher at Sustainable Finance Lab, Utrecht University on the importance of green roofs / vegetated roofs as nature-based solutions. Toxopeus is involved in the EU-wide project Naturvation, a project with the aim to assess what nature-based solutions can be achieved in cities, and what tools are required to realize urban sustainability goals. https://naturvation.eu/home Also, we wanted to understand more about the financial aspects of installing green roofs: what financial incentives are there available in the EU region? Folkert Tempelman from Studio Piso7 conducted the interview on behalf of Purple-Roof. Purple-Roof website: https://www.purple-roof.com/

What Is A Combined Sewer? written and narrated by Dr. Anna Zakrisson ____ Does your city smell of poo from time to time? It is quite likely that you have felt a whiff of such unpleasant odors after heavy rain events. But, have you ever stopped and asked yourself why this happens? You might not like the answer… The reason is: overflowing combined sewers. Find out how green roofs can help to mitigate this serious problem! ____ ______ Read the full article on the Purple-Roof blog: https://www.purple-roof.com/post/what-is-a-combined-sewer _______ Don't hesitate to contact us if you have any questions at info@purple-roof.com

What is green roof retention? Written by Brad Garner and narrated by Dr. Anna Zakrisson. _____ Retention is the process of holding water on the green roof, i.e., preventing water from draining off the green roof. Retention has been the focus of the hydrologic design of green roofs over the past few decades. Many people familiar with green roofs but less familiar with other types of stormwater management might not realize that most engineers consider retention the “free gift with purchase” rather than their central stormwater goal. So, what is this odd thing, retention? The secret of green roof water retention is green Retention works like this: rain falls onto a relatively dry green roof, and the green roof absorbs the water, usually in pore spaces. Later, the sun comes out, and the plants use the rainwater to evapotranspire. This means that the water leaves the roof as vapor. Eventually, it rains again, and the process is repeated. A surprising amount is going on there.
