Description of the project

Summary

With our project “From grey to green” we are connecting the green shades of green infrastructure into daily life of us, our children, our society and community, by which we live the principal points of the Commission’s NEB already now.

In 2020 we have installed a green roof system on the roof of primary school in Slovenia, Kranj. 250 m2 of school roof is planted by various types of greenery. Green roof brings to children and teachers’ outdoor classrooms, where they can learn and transfer the theoretical knowledge of natural science into practice by planting different plant varieties, teaches them how to care for them during the year.

Our project aligns closely with the NEB' principles of multilevel engagement by actively involving a diverse range of individuals (children & teachers), organizations (school), companies (local architect biro) and communities (municipality Kranj). With connecting all participants with bringing the green roof in their community, the benefits can be seen on multiple layers.

Our project aligns with the NEB "Reconnecting with Nature" theme by enhancing biodiversity and contributing to climate and environmental indicators. Green roofs are effective at capturing pollutants and filtering the air. This aligns with the NEB’s goal of creating healthier living environments by using nature-based solutions to improve air quality; through their cooling and shading properties, green roofs help mitigate urban heat island effect and making cities more pleasant.

The project aligns closely with the NEB’s value of inclusion by actively involving a diverse range of individuals, organizations, and communities. We empower young people to participate in design and implementation of green roofs and roof gardens, instilling a sense of responsibility for sustainability. Outdoor classrooms on green roofs enable hands-on learning, bridging theory and practice in natural science. This investment in children's green education benefits future.

Key objectives for sustainability

Our project From grey to green aligns with sustainability aims by enhancing biodiversity and contributing to climate and environmental indicators. Green roofs are effective at capturing pollutants and filtering the air. This aligns with the NEB’s goal of creating healthier living environments by using nature-based solutions to improve air quality; through their cooling and shading properties, green roofs help mitigate urban heat island effect and making cities more pleasant.

Our green roofs systems are non-conventional solutions of green infrastructure, since we are using specially
designed growing media instead of traditional soil on the green roof. On average our green roof growing
media is 8-10 times lighter than other regular green roof substrates, so our Green Roof system can also be
installed on lightweight constructions where traditional systems are impossible to use. This is especially important for renovation of buildings. Beside that, our growing media is made of natural, fire
resistant material, which brings more safety on the roof.

Ecological benefits of green infrastructure thus include localized climate control, but also extend across wider municipal regions. Green roofs are one of the most effective ways to reduce the ambient air temperature in urban areas. During summer the temperatures in cities are approximately 5-7ºC higher than in the countryside and the temperature on the traditional roof can be up to 40ºC higher compared to the green roof.

Green roofs additionally help to reduce the amount of CO2 in the air, which is considered one of the most important causes of global warming. The plants on green roofs can also capture airborne particles such as smog, and volatile organic compounds from the local atmosphere which has a positive effect on air quality and health of inhabitants.

Key objectives for aesthetics and quality

Our project is committed to the NEB aesthetics and quality of experience. We prioritize design excellence, making green roofs visually appealing and harmonious with urban environments. We draw inspiration from nature and integrate elements of biophilic design for a deeper connection with nature.

Collaborating with local architects, we incorporate art into green roofs through sculptures, murals, or installations reflecting the community's artistic identity.

Our green roofs engage all senses, offering scents, sounds, and tactile experiences. They serve as social spaces for children, fostering outdoor interaction, learning and relaxation.

We prioritize plant diversity and seasonal changes, ensuring a dynamic, year-round aesthetic and sensory experience. Educational elements, such as signage and guided tours, enhance visitors' understanding of green roofs' ecological functions.

Our green roofs seamlessly integrate with surroundings, enhancing the overall urban landscape and neighborhood character.

In summary, we embody the New European Bauhaus' aesthetic and experiential values, creating green roofs that blend design excellence, artistic integration, sensory engagement, and education for a deeper connection with nature and the community.

Results in relation to category

By installing green infrastructure into our surroundings, we have a chance to start living the green presence already now. Green Roofs are showing the power of buildings and their environmental, health and wellbeing benefits. Following our mission to paint the future green, we provide the people the possibility to live in greener urban areas, where they can experience higher life satisfaction and lower mental distress.

In 2020 we have installed a green roof system on the roof of primary school in Slovenia, Kranj. 250 m2 of school roof is planted by various types of greenery, of which 150 are extensive, 70 are perennial plants and herbs, and 30 are edible plants (raspberries, blackberries, vines and strawberries). Green roof brings to children and teachers’ outdoor classrooms, where they can learn and transfer the theoretical knowledge of natural science into practice by planting different plant varieties, teaches them how to care for them during the year.

With building this green opportunity we gave the children the power to live the nature and start to understand and feel the importance of green infrastructure in their life. We believe that the investment into children green education will benefit to further generation on a larger scale.

With a view of the city from the green roof, students can learn orientation in space, how the sun moves, they are able to solve tasks by observation, as we have also set up various meters - for water, humidity, sunlight... The students who take care of the gardens, learn also concerns and responsibilities, which will then be handed over to younger students.

Innovative character

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. The natural character of green roofs provides relief from the concrete construction in urban areas.
Our green roofs systems are non-conventional solutions of green infrastructure, since we are using specially designed growing media instead of traditional soil on the green roof. On average our green roof growing media is 8-10 times lighter than other regular green roof substrates, so the Urbanscape® Green Roof system can also be installed on lightweight constructions where traditional systems are impossible to use. This is especially important for renovation of buildings.
Our Green Roof System can also be much thinner than traditional green roof systems and has a superior water retention capacity, since it can hold up to 3-4 times more water per its volume than other green roof substrates. Therefore less thickness is needed to achieve the same water absorption.

Beside that, our growing media is made of natural, fire resistant material, which brings more safety on the roof. Urbanscape® Green Roof System is provided instant green, with complete, easy-to-install layers. Due to the use of the new innovative Urbanscape® Green Roll, no special equipment is required for installation and maintenance.

Disciplines/knowledge reflected

Our project aligns closely with the New European Bauhaus's principles of different disciplines and knowledge engagement by actively involving a diverse range of individuals (children & teachers), organizations (school), companies (Green Roof System provider, local architect buro) and communities (municipality Kranj). With connecting all participants with bringing the green roof in their community, the benefits can be seen on multiple layers.

Integrating green infrastructure at a local level can be achieved through various measures on any level.

Youth Engagement: we have actively engaged with young people, recognizing them as the future custodians of our environment. Our project provides opportunities for youth to participate in the design, and implementation of green roofs, as well as a creating a roof garden. This involvement empowers them to shape their environment and introduces a sense of responsibility for sustainability. Green roof also drives children and teachers to spend more time outdoor in outdoor classrooms, where they can learn and transfer the theoretical knowledge of natural science into practice.

Green Roof System provider: We as a green roof system provider have provided technical knowledge for the project to be implemented in the city Kranj. During the design and implementation of our project “From grey to green” we have provided technical solution for this specific project and have collaborated with local architects, to proved the best solution to the market.

Community Collaboration: We collaborated with local community in town Kranj to ensure that the green roofs we create meet their unique needs and preferences, especially in sense of improving storm-water management, increasing the green surfaces and improving biodiversity. This collaborative approach allows us to address specific community challenges, such as urban heat islands or limited green spaces, while fostering a sense of ownership and pride among residents.

Methodology used

We have worked with the local community and municipality in Kranj to tailor green roofs to their needs, addressing specific challenges like urban heat islands, limited green spaces and especially to meet technical requirements of the project.

Our technical team in company has provided technical calculations for the project as well has prepared the whole conceptual documentation of benefits, that will bring to school, children, educational stuff and broader community.

We have engaged the youth, where we empower young people to participate in the design and implementation of green roofs and roof gardens, instilling a sense of responsibility for sustainability. Outdoor classrooms enable hands-on learning, bridging theory and practice in natural science. This investment in children's green education benefits future generations.

On a national level we actively seek public input through surveys, meetings, and workshops, ensuring green roof designs reflect community values and aspirations. The project “From grey to green” emphasize the transformation of grey infrastructure to green one, which can be implemented in every city on a national level. It is a good case-study for other Slovenian cities, where we bring nature into the cities, and provide an investment in children's green education for future generations.

Global challenges

Climate benefits

Researchers have shown that even small green areas benefit their surrounding environment, lowering air temperatures outside their immediate boundaries. Ecological benefits of green infrastructure thus include localized climate control, but also extend across wider municipal regions and mitigate against wider climatic issues. Several studies have shown the ability of green infrastructure solutions to minimize the risks of urban flooding by controlling water runoff, while also improving the water’s quality through filtration.

Green roofs are one of the most effective ways to reduce the ambient air temperature in urban areas. During summer the temperatures in cities are approximately 5-7ºC higher than in the countryside and the temperature on the traditional roof can be up to 40ºC higher compared to the green roof. Green roofs additionally help to reduce the amount of CO2 in the air, which is considered one of the most important causes of global warming. The plants on green roofs can also capture airborne particles from the local atmosphere which has a positive effect on air quality and health of inhabitants

Environmental benefits

Green roofs have the potential to be designed specifically to support biodiversity in cities and act as a corridor to facilitate the movement and dispersal of species. Green roofs act as refuge habitats for numerous arthropod species and allow them to move and disperse within urbanized areas. Together with other green surfaces (parks and gardens) and by connecting to natural areas in the countryside, they support a network of pollinator habitats in the wider landscape.

In 2019 we have performed a study on pollinators on our Green Roof together with the Slovenian National Institute of Biology (NIB), where two Green roofs, located in industrial and urban areas, were monitored. Results show the high importance of green infrastructure for biodiversity and also for pollinators conservation.

Learning transferred to other parties

All phases of the project – project design and set up, project calculations, collaboration with local companies and municipality and project implementation can be transferred to other places and communities in the country.

By installing green infrastructure into our surroundings, we have a chance to start living the green presence already now. Green Roofs are showing the power of buildings and their environmental, health and wellbeing benefits. Following our mission to paint the future green, we provide the people the possibility to live in greener urban areas, where they can experience higher life satisfaction and lower mental distress.

Our green roofs systems are non-conventional solutions of green infrastructure, since we are using specially designed growing media instead of traditional soil on the green roof. On average our green roof growing media is 8-10 times lighter than other regular green roof substrates, so the Urbanscape® Green Roof system can also be installed on lightweight constructions where traditional systems are impossible to use. This is especially important for renovation of buildings.
