Europe: Expect a hot summer, with draught and major storms - can Green Roofs help?

Posted by Maja Tomazin on Jun 1, 2018 2:39:46 PM

There we have it. The AccuWeather weather portal has published its summer weather forecast.

The AccuWeather portal is forecasting weather in the Eastern Europe area from June through August will see high temperatures and droughts. However, no longer heat waves were announced, since occasional major storms are expected to cool the atmosphere, bringing with them hail and storm water flooding.

Green roofs: Making life more comfortable for residents of houseboats in Amsterdam

Posted by Maja Tomazin on Mar 14, 2017 3:57:17 PM

To provide more comfort to houseboats in Amsterdam Sedumworld applied Urbanscape Green Roof System featuring Urbanscape Green Roll and Sempergreen Sedum-mix blanket.


Standard houseboats – the sun raises indoor temperatures during summer

The houseboats have an lightweight wooden roof construction with a minimum insulation. In the summer the transfer of solar energy dramatically rises the indoor temperature.

Different Green Roofs for different local needs and environments

Posted by Jure Sumi on Feb 13, 2017 2:50:07 PM

We have been talking on many of our blogs about the real performance of green roofs, in terms of improved energy efficiency, better storm-water management, lower heat-island effects and more – because it’s all about achieving good environment performance.

However, this time we look at green roofs from the customer’s perspective, and what they expect from the green roofs.

Over the past years I’ve learned that many customers do occassionaly read more in details what green roofs are and know what green roofs bring; but when it comes to initial discussions you can clearly see that there are certain local aspects and requirements that contribute to the fine-tuning of green roof design.

Wind up-lift and wind resistance of Green Roofs

Posted by Jure Sumi on Nov 22, 2016 10:24:07 AM

Many studies have been made and published related to wind resistance of Green Roofs, but in reality there is still a lack of consensus in the international green roofing / building industry on what kind of testing and certification would be most appropriate and representative of real wind effects on vegetated roofs.

Physics behind wind-suction

If we first look at the facts, we don’t often hear of green roofs having been blown-off during storms. Such an event might happen with pavers, waterproofing and similar, but this is not the case with green roofs.

But do we know why?

Management of rainwater with Green Roofs

Posted by Maja Tomazin on Nov 14, 2016 10:46:21 AM


In the majority of developed cities, Green Roofs make up about 40–50% of regulated urban surfaces. The quantity of rainwater from these roofs makes a significant contribution to the total volume of water that is channelled into the sewage network. This is the very reason rainwater is one of the main causes of floods in urban environments.

Do you really know all the benefits of green roofs?

Posted by Maja Tomazin on May 23, 2016 3:26:48 PM

Green roofs have recently gained great attention of urban planners and architects - mainly because of numerous social, economic and design-based benefits they bring to public, private, economic and social sectors, and even more important, to local and global environments.

You've all heard about how green roofs go beyond the meaning of contemporary architecture and give a new value to the role of buildings within urban planning. You also know they are designed not only to bring back the natural element in the urban environment, but also to provide solutions for important issues such as urban heat island effect and stormwater management.

What about other benefits? Do you really know it all?

Let's check all 3 categories of green roof benefits - environmental, economic and last but not least, social benefits of vegetative roofs...

Utilizing roofs: Photovoltaics on green roofs

Posted by Maja Tomazin on Mar 8, 2016 4:27:37 PM

Roofs can be seen in so many more ways than just the top of a buildingas a complex structure accommodating a roof with solar panels, wind turbines and other equipment, as well as a green roof, which has many ecological benefits and can in some cases even be seen as a leisure area.

Green roofs have a proven track record of providing many benefits, such as improved air quality, effective temperature regulation and energy conservation, protection of the building envelope, improved longevity of roofing membranes, and various economic and ecological benefits, as well as providing an attractive, aesthetically-pleasing environment.

Do green roofs need to be maintained and irrigated for maximum performance?

Posted by Maja Tomazin on Feb 8, 2016 2:14:55 PM

Designers, investors, project owners and other stakeholders often have questions about the maintenance of green roofs. It’s important to be realistic, and to take into account all of the many aspects of this question.

Let’s start with the most important one: what does the owner want and expect from his green roof? When someone decides for an extensive green roof solution it’s clear that use of green roof spaces for recreational and leisure activities is rather limited. Is the decision then related to the owner’s personal attitude; their hope of making a greener world, of reducing CO2 emissions? Or did the owner recognise the possibilities for energy savings in cooling and heating the building? Whatever the reason, the roof should be kept in good condition if the owner wants the green roof to deliver optimal water retention, energy conservation, a naturally beautiful appearance and more. For this healthy, vigorous plant growth is necessary.

How much does a Green Roof weigh?

Posted by Maja Tomazin on Nov 27, 2015 3:01:22 PM

Green roofs may come in an endless variety of shapes and sizes from high-rise public parks and lush rooftop gardens to tranquil urban spaces, but there is one critical factor that has a major impact on them all — weight.

Green roof weight can range from hundreds of tons for an ‘intensive’ green roof such as a small urban park or garden to just a couple of hundred kilos for a lightweight ‘extensive’ green roof system like Urbanscape featuring a lush mix of sedum vegetation.
