Want to know more about green roofs? Then, you have come to the right place! This is the audio-article and podcast channel of Purple-Roof. We believe that the true magic happens when there are collaborations across fields such as between engineers with architects, economists, biologists and many more. This is our mission: true sustainability and a great future ahead for the entire green roof industry. If you want to read more about Purple-Roof take a look at this: https://purple-roof-site/post/story-of-purple-roof What is Purple-Roof? Purple-Roof is not a product but a non-proprietary specification. Architects and engineers can specify Purple-Roof for their projects, with the ease of specifying a manufactured product. However, with the benefit of knowing that the project can be competitively bid without breaking spec. We believe that: 1. Research is key 2. Economic sustainability is critical to long-term environmental sustainability. 3. Green roofs should not be one-size-fits-all. Find us at 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:...

What is green roof retention?

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”...

Green Roof Plants - How do They Survive Written and narrated by Dr. Anna Zakrisson for Purple-Roof. www.purple-roof.com/ _____ Pests and green roof plants During which parts of your life did you get the most infections? If you’d allow me to make a qualified guess, I’d probably say that it has been during times of high stress, mentally and/or physically. If we sleep little, eat poorly, and stress a lot, we tend to get sick. In a way, this is also the case for plants, through their stress...

Green Roof Plants - How do They Survive Written and narrated by Dr. Anna Zakrisson for Purple-Roof. www.purple-roof.com/ _____ Do green roof plants matter? Yes, absolutely! The vegetation on a green roof is a central part of the engine that drives evapotranspiration. Evapotranspiration helps to ensure efficient green roof stormwater management. Also, if the roof isn’t covered by a protective layer of vegetation, the soil might simply blow away or even flush away during a rainfall. Selecting...

Green Roof ROI - What's the Deal? Written by Oscar Warmerdam and narrated by Dr. Anna Zakrisson https://www.purple-roof.com/ _____ Almost all green roofs are sold in regulatory environments where there are incentives, and rebates, but mostly requirements to build green roofs. Often, the million-dollar question is dodged: “What is the real economic benefit of building a green roof?” How is it possible that in Washington DC more or less every building has a green roof, but just over the border...

Green Roof Soil - Great Opportunities Ahead! Part 2 by Purple-Roof Written and narrated by Dr. Anna Zakrisson _____ Green roofs can retain a lot of rainwater. Small and medium storms are generally not a problem. A roof can retain about 80% of the frequency of all storms, but these storms are routine rain events, and they only make up about 50% of the total rain volume. The remnant 50% is what becomes a flooding risk. This 50% is the Achilles heel of the current green roof industry but is an...

Green Roof Soil - Great Opportunities Ahead! Part 1 by Purple-Roof Written and narrated by Dr. Anna Zakrisson _____ Green roof soil biology – why should I care? Traditionally, green roof soil biology (or soil health) has not been considered a central factor for improving stormwater management or nutrient runoff in green roofs. This life-giving layer has merely been viewed as a compartment for water, and the intricacies and complexities of the biological systems have often been ignored. We...

Are Green Roofs True Stormwater Management Tools? Part 3 by Purple-Roof An audio article by Oscar Warmerdam ______ Detention is the process of absorbing or holding water during a storm, then slowly releasing it. Unlike retention, detention works regardless of the weather. When a detention-oriented system drains, it recharges. So, a detention-oriented green roof can recharge quickly, and be ready for the next storm, or the tail end of a large storm. Even in dark and cloudy weather! Retention...

Are Green Roofs True Stormwater Management Tools? Part 2 An audio article by Oscar Warmerdam. ________ Why retention is unreliable for stormwater management at the building scale. Retention can be unreliable because it doesn’t work in repeat storms, large storms, or during cool and cloudy weather. Why? Water that is retained, by definition, leaves the green roof only via evapotranspiration. If there is no time for evaporation, such as during big storms or repeat storms, or if weather...

Are Green Roofs True Stormwater Management Tools? - Part 1 An audio article by Oscar Warmerdam. Green roofs are often sold as stormwater management tools. And that is true: green roofs do manage stormwater but mostly as a volume reduction tool. This volume reduction has huge benefits on a city scale. The benefactors are the taxpayers, citizens of what is now a city with cleaner water, and cleaner air. This is why many progressive cities have regulations in place that promote green roofs....

What Is Evapotranspiration Part2 by Purple-Roof

More
What is Evapotranspiration Part 2: Green roofs are tricky. On the one hand, we want evapotranspiration to be very high to get rid of stormwater as quickly as possible and prepare to absorb the next storm. On the other hand, we want the plants to conserve water to not dry out in the thin soil media between storms. We also do not want to have to irrigate green roofs to support plants. It is a challenging task to design a plant palette that minimizes the need for additional irrigation. LEED, in...

What is Evapotranspiration Part I: Detailed knowledge of evapotranspiration rates is essential for a successful green roof. In this audio article, we dive into the topic of evapotranspiration. If you would like to read the article, it is available here: https://www.purple-roof.com/post/what-is-evapotranspiration Evapotranspiration is merely a combination of the words: evaporation (evapo-) and transpiration (-transpiration). But what do these two terms mean? Let’s start with evaporation!
