01.05.2017: Remote Sensing – Green Roof Inventory and Potential Analysis

Green Roofs can help to adapt cities for climate change, through the provision of cooler microclimates and reduced stormwater run-off. They also enhance biodiversity in urban ecosystems. In order to evaluate these positive effects in a quantitative way, information about the already existing Green Roofs and potential Green Roof sites are needed. The German Aerospace Center (DLR), the German Roof Gardener Association (DDV) and different German cities developed a method with which existing Green Roofs and potential roof areas can be identified and inventoried from a "birds-eye view". The project received funding from the German Federal Environmental Foundation (DBU).

19.12.2016: IGRA Green Roof News 2-2016

The second issue of our Green Roof News Journal 2016 has just been released. The main theme of this journal is about "Stormwater Management".

One only needs to listen to the news or read the local paper to hear of all too common stories of flooding and property damage caused by seemingly routine rainfall events. Green Roofs help in reducing the amount of stormwater runoff. This results in decreased pressure on sewer systems at peak flow periods.

22.03.2016: IGRA Green Roof News 1-2016

We are very pleased to inform you, that the first issue of our Green Roof News Journal 2016 has just been released. The main theme of the journal is about “Productivity and Healing – Benefits of Green Roofs”. In a knowledge work economy, people are the engine that keeps companies growing, adapting, improving and innovating. A University of Melbourne study shows that glancing at a grassy Green Roof for only 40 seconds markedly boosts concentration. Other studies of the designs of green space and Green Roofs in working environments and healthcare have shown that effective and innovative landscape design can be a powerful tool for supporting employee performance and patients' recovery by significantly improving productivity, health and wellbeing.

You can find information about the benefits of Green Roofs on productivity and recovery as well as news from the new remote sensing technology and further reports from Green Roofs worldwide in the UK, Poland, Netherlands, Greece, Portugal and Denmark in this issue.

We hope you will enjoy the articles and share them with your colleagues.

13.08.2015: The Nature of Cities Roundtable Green Roofs

Why don’t all public buildings have green roofs? Or all large private buildings (e.g. businesses)? Would this be a good idea? What would it take to make it happen and to make it worthwhile?

Many of the benefits of green roofs are appreciated and increasingly well studied: storm water management, mitigation of heat islands, insulation, biodiversity, green space for enjoyment, and so on. With these benefits why don't more buildings—especially large ones—have green roofs? Should all public buildings and large new construction be required to have green roofs? These are obviously complicated technical and political calculations about the real and perceived values of green roofs, what they cost to build and maintain, and whether greens roofs are "worth it". So, would programs to significantly expand the use of green roofs make sense? If so, how can we better make the case—say, with better data or more effective outreach—to elected officials, to developers, or to the public?

01.08.2015: IGRA Green Roof News 2-2015

The new Issue of the IGRA Green Roof News Journal has just been published. The main theme of the journal is about urban Green Roof policies and the launch of the International Green Roof City Network. Cities such as Paris, Rotterdam, Stuttgart, Portland, Linz or Singapore have long recognized that vegetation on roofs is offering a high potential for the improvement of the urban climate and the reduction of the “urban heat island effect“. Green Roof Policies play a very important role for their sustainable urban planning. The International Green Roof City Network is a platform to facilitate the application of Green Roofs Policies within a city. Read more about the Green Roof Policy Toolkit and innovative projects from Denmark, Belgium, Portugal, South Africa, USA and Germany.

09.05.2015: Review 4th International Green Roof Congress 2015

It was a Congress which has no equal. Superlative Green Roof projects, outstanding speakers, top-class presentations and an international collegial atmosphere made the two days at the 4th International Green Roof Congress in Istanbul from April 20–21, 2015 a Green Roof industry highlight.
This year's Congress of the International Green Roof Association (IGRA), under the patronage of the Istanbul Metropolitan Municipality, was a Green Roof conference that may be considered unique in the world, not only in terms of its 500 participants from 35 different countries. Featured Green Roof projects such as Marina Bay Sands, a landscape park in Singapore standing almost 200 meters above sea level, Bosco Verticale, a double-towered skyscraper in Milan with a façade-forest hosting more than 700 trees, and the congress venue itself, the Zorlu Center in Istanbul, whose roof garden is built on an elevated grade of 33 meters and has an area of 62,000 m², complete with swimming pools.

"The Sky is the limit – Nothing is impossible" – renowned speakers from various disciplines led the participants to the realization that the green building industry is advancing into new dimensions and that, true to the congress motto "Explore the Nature on Rooftops," there is much to discover in terms of new utilization. As part of the theme "Green Roofs in Mediterranean and Dry Climates" participants learned how transferring the Oasis Principle can change the concrete deserts typical of urban rooftop locations into charming oases. Projects from Armenia, Italy, Greece, Lebanon, Egypt and Turkey have thereby set new standards. The congress proceedings are available at

01.04.2008: Living Roofs Technical Report launched

The Technical Report has supported the development of a new Living Roofs Policy in the London Plan which will promote the adoption of Living Roofs across London. The policy states that the Mayor will, and boroughs should, expect major developments to incorporate living roofs and walls where feasible. It is expected that this will include roof and wall planting to deliver a number of objectives including accessible roof space, adapting to and mitigating climate change, sustainable urban drainage, enhancing biodiversity and improved appearance. Boroughs should also encourage the use of living roofs in smaller developments and extensions where the opportunity arises. The document features several case studies and a wealth of useful information. A PDF copy of the report is available for download from the GLA web-site and from Alumasc at
