EU Policy Innovations Support Green Infrastructure Amid Climate Transition

University Warsaw’s Library – Beautiful and Multi-Functional Rooftop Gardens.  Policy innovation is key to increase green infrastructure amid the combined climate, energy and health crisis, writes Luigi Petito for Living Architecture Monitor. Read how the next 18 months are key for EU green legislation. We live in a time of unprecedented social, environmental, and economic change. To manage and hopefully guide the transition, and to address the multiple challenges it raises, particularly when it comes to the climate, we need innovation and resilience. Resilience and innovation go hand in hand. We show resilience in our capacity to face multiple crises, for example the combined climate, energy and health crisis, adapt and rethink what we consider taken for granted. When we innovate, we go beyond resilience, bringing forward new ideas, methods and devices that provide solutions. The green transformation of cities is the quintessence of resilience. We have a large body of evidence showing that the deployment of green infrastructure in urban areas delivers solutions to adapting to and managing environmental and societal challenges ranging from rainwater management to increased biodiversity, energy savings and the improved mental health and wellbeing of citizens.  Read the full article by Luigi Petito in Living Architecture Monitor.

Renaturing Cities and Restoring the Natural Water Cycle Through Green Infrastructure

Rotterdam, The Netherlands. ID: 1121792051 In July, the European Commission’s Joint Research Centre published the “Drought in Europe – July 2022” report, an assessment of Europe’s drought situation based on the European and Global Drought Observatory. The report showed that a staggering portion of Europe was exposed to warnings (44 per cent of EU+UK) with serious consequences ranging from vegetation stress to severe impacts on farming and the energy sector (for both hydropower generation and the cooling systems of nuclear and thermal plants). The report anticipated that warmer and drier than usual conditions were (and they actually are) likely to occur in the western Euro-Mediterranean region until November 2022 with some precipitation, in many cases associated to thunderstorms, foreseen to alleviate drought conditions while causing damages and further losses.  Read the full article by Luigi Petito in the Autumn 2022 issue of Living Architecture Monitor.

Renaturing Cities and Restoring the Natural Water Cycle Through Green Infrastructure

Investments in urban green infrastructure is the solution to extreme weather events, writes Luigi Petito for Living Architecture Monitor.​ ​ The good thing is that we have solutions to mitigate these extreme phenomena. One of these solutions is investment in urban green infrastructure. In cities we must and can restore the natural water cycle with existing technologies. We must renature densely populated areas with blue-green infrastructure on roofs, allowing water infiltration, rainwater harvesting, evapotranspiration, urban heat island effect mitigation and decentralised stormwater management. straight from the source Rotterdam, The Netherlands, June 3, 2018: close-up of some of the shops and the public park on top of them at Dakpark Rotterdam, The Netherlands, June 3, 2018: close-up of some of the shops and the public park on top of them at Dakpark

“A building as a powerhouse of creativity”- Axel Springer’s new building in Berlin

With the new Axel Springer building in Berlin, Axel Springer SE is following the current paradigm shift in the world of work. With the new Axel Springer building in Berlin, Axel Springer SE is following the current paradigm shift in the world of work. Work is being rethought today, with value creation being understood in such a way that every employee is empowered to develop his or her full potential. This presents employers with special challenges. Mathias Döpfner, CEO of Axel Springer SE, accordingly formulated the objective for the new office complex: “With the new building, we wanted to create a symbol and an accelerator of our own change. The brief, long before Corona, was to answer the question why office space is still needed at all in the digital age. Rem Koolhaas has succeeded spectacularly. Open multifunctional spaces that allow maximum flexibility of use. Avant-garde architecture as a magnet for encounters and communication. A house as a powerhouse of creativity.” The ambitious project was launched as a planning competition with 18 architecture offices. The decision was then made in Spring 2014 in favour of the design by Rem Koolhaas of the Dutch office: Office for Metropolitan Architecture (OMA). The new cube-shaped Axel Springer building in Berlin extends over the Lindenpark site, in the heart of the former newspaper district, with a built-up area of around 9,100 m². It complements the Axel-Springer-Kiez, the ensemble of various premises at the headquarters of the media and technology company. The new building is located on the former course of the inner-German border, which runs symbolically right through the building. Bringing the divisions and brands together in the new building enables better networking and knowledge exchange among them. The extraordinary architecture not only stands for the future of work, but it is also a symbol for the digital and cultural transformation of Axel Springer. Greened event areas on the roof of the office building: Tinted glass surfaces characterise the façade of the light-flooded office building. At the same time, the used roof area offers an attractive space for events. The greenery transforms the roof area into a green oasis in the middle of the city. With this in mind, an attractive roof garden was created, which offers the more than 5,500 employees in the Axel Springer neighbourhood the opportunity to spend their lunch break or after-work events in the green. Various event areas have been created for this purpose. Long paths between the green spaces invite to go for a walk – or to visit the “REM”, the gastronomic offer spread over three containers and named after the architect Rem Koolhaas. The roof surface slopes downwards to the outside towards the drive-in system. The slope is executed with the help of the Optigrün system solution pitched roof with thrust protection and extensive greening. In the middle of the roof are the Optigrün system solutions Garden Roof and Landscape Roof, partly with substrate heights over 40 cm for intensive green roofs, which also allow the planting of trees. The Optigrün FKD 60BO drainage and water storage elements used here have a high water storage capacity, prevent waterlogging through the rapid drainage of excess water and thus ensure the irrigation of the vegetation. The Optigrün FKD 10 drainage elements, which are also installed, ensure a high drainage capacity under the accessible traffic routes and areas.    Roof Accessibility/Amenity: The employees of the media and technology company already use the roof garden extensively and enjoy the green oasis in the city. Especially during the extreme temperatures in summer, the green roof provides a pleasant environment. The evaporation through the greenery reduces the temperatures on and around the building. At the same time, the greenery binds CO2 and fine dust. And the green roof, which has grown well in the meantime, also provides an additional habitat for flora and fauna.

European Union relies on green roofs in cities and towns to help reach new biodiversity targets

Green and blue infrastructure give an essential contribution to urban biodiversity, writes Luigi Petito in the Summer edition of Living Architecture Monitoring. On June 22, the European Commission proposed the first EU Nature Restoration Law in the form of unprecedented legally binding urban biodiversity targets. Such targets are intended to boost a systematic integration of vegetation into urban planning, including in public spaces, infrastructure, and in the design of buildings, in particular of their roofs and facades, and their surroundings.

Different green roofs for different local needs and environment

We have already been talking 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 the expectations of green roofs from the customer’s perspective. There are certain local aspects and requirements that contribute to the fine-tuning of green roof design. Let’s narrow these aspects down to 4 crucial elements: • climate conditions where the green roof will be set-up • type of building and type of roof where the green roof will be installed • the future purpose of the new green space being installed • local legal requirements We will not go into any theoretical debates here, but rather focus on two borderline case stories, where customer needs particularly determined the type of green roof construction, and where employing a traditional green roof simply doesn’t work. DUBAI, UAE Let’s first start with the climatic conditions that green roofs need to survive under extreme heat and humidity. And when talking about extreme, we’re talking about summer daytime temperatures that can easily exceed 50º C / 120º F. a roof on a four-storey building that connected two residential skyscrapers recreational space where residents could meet and relax There were a few main requirements on the investor’s side: The green roof needs to be lush, so that residents will see it as a real field of flowers and grasses The green roof should not be too heavy, as the area dedicated to installation of the green roof was a roof covering meeting rooms below The green roof can be irrigated, but should not require more irrigation water than what the Dubai code specifies for parks and gardens Initially, this seemed too much of a challenge to overcome. Knauf Insulation had to design a green roof no larger nor greater than 60 kg/m2 (12 lbs/ft), that would not consume more than 8 litres/m2 (0.3”) of water per day in the highest summer months, and would continue to look lush and green. Just look at what they were able to develop using only 6 cm (2.5”) of growing media, which weighed less than 50kg/m2 (10lbs/ft) fully saturated. A roof on a four-storey building that connected two residential skyscrapers recreational space where residents could meet and relax RIGA, LATVIA This other project was entirely different in terms of climate conditions. The project was executed in the Baltics – in Riga, Latvia – where winter temperatures can easily drop well below -20º C / -5º F. Like the Dubai case, the Riga green roof was built in a residential area. The roof between the residential buildings was meant to be a recreational space, where families could relax late in the afternoon and watch kids play in the rooftop-playground. The simplest green roof structure using grass over the entire roof would have been the cheapest alternative; however, this would actually require a lot of maintenance over the years to come, which would be a burden for future residents, so this idea was initially scrapped. The following requirements were drawn up for Knauf Insulation to follow: • The green roof needs to be fully vegetated on the day the first residents arrive • The green roof should remain nice, even in the colder winter months when not covered in snow • The green roof should require a minimum of maintenance, meaning low additional costs for the residents • The original design should make the roof thicker than the pathways made of concrete paving stones • The green roof must act as a storm-water management tool. The difficult part here was to provide sufficient storm-water management with a thin structure that would not exceed the height of the pavers. This cannot be done with regular green roof soil, so a structure that employed Urbanscape Growing Media, just 4 cm thick (1.8”) was used. This 4 cm thick structure could still hold the majority of the annual rainfall (more than 70%) that usually pours down on the roofs of Riga. Once built and ready, the entire place looked fantastic, and complied with all of the initial requirements. We all know that Urban Green Infrastructure is truly the industry of the future and in order to support faster growth, we need to respect the needs and wishes of our potential users. Sometimes this means that the need to look outside the box and beyond traditional ways of doing business.

Urban Biodiversity Targets Lay the Ground for Holistic Exploitation of Rooftops in European Cities

Macro of a honey bee (apis mellifera) on a mint (menta piperita) blossom. ID: 1574704057 Green and blue infrastructure give an essential contribution to urban biodiversity.   Back in May 2020, the European Union presented its biodiversity strategy for 2030 – a comprehensive plan to protect nature, reverse the degradation of ecosystems and put Europe’s biodiversity on a path to recovery by 2030. The strategy recognises that greening urban and peri-urban areas is a refuge for nature and provides a wide range of benefits for people. The strategy announced that the European Commission will have put forward – subject to an environmental, social, and economic impact assessment – a proposal for legally binding EU nature restoration targets to restore ecosystems and help to increase biodiversity, mitigate and adapt to climate change, and prevent and reduce the impacts of natural disasters. With nearly half of the EU population projected to live in urban areas by 2050, greening cities an increase urban biodiversity is a must.
