Description of the project

Summary

The modular green wall by Parkly and Innogreen is an innovative green infrastructure with numerous proven advantages. Functioning as a shield against traffic noise, this green wall emphasizes the pivotal role of green infrastructure in mitigating noise pollution within urban settings, while simultaneously delivering diverse visual, health, and environmental benefits.
The primary objective of this wall is to establish an oasis characterized by a pleasant auditory environment and available seating. Its vegetation and shading properties not only create a cooler spot for individuals seeking respite on warmer days but also provide a sanctuary for both people and pollinators. Furthermore, the modular structure makes it easy to create different sized configurations - or move it in different locations.
The modular green wall represents a deliberate step toward enhancing urban spaces with increased greenery and enhanced comfort. Studies have substantiated that green spaces contribute to improved well-being, while diverse plant life within urban areas significantly bolsters biodiversity. This initiative fosters healthier and more harmonious urban environments.

Key objectives for sustainability

The primary sustainability goals focus on tackling urban challenges through nature-based solutions. Mitigating traffic noise remains a priority while concurrently establishing a visually appealing environment for relaxation and social interaction which is accessible and open for all. The space formed by the modular green wall is not only inviting but also contributes to cooling, thereby addressing the urban heat island effect. The vegetation actively draws in a diverse array of insects and pollinators, serving as a vital source of sustenance and refuge for them.
Moreover, the element's sustainability is realized through a circular furniture system: every Parkly-component, module, and structure can be repurposed in different locations and configurations, ensuring an ongoing cycle of reuse and reducing environmental impact.

Key objectives for aesthetics and quality

The solution places significant emphasis on aesthetics, evident in both the design of the modular system and its overall appearance, including the careful selection of plants. User-friendliness is also a priority, demonstrated by strategically locating pollinator-friendly plants not only adjacent to the seating area but also on the rear side of the wall. This design enhances comfort: while users can observe the pollinators, the insects remain separate, flying and staying on the opposite side. Additionally, the choice of colors and materials for the modules prioritizes durability, sensory comfort, and tactile appeal.

Key objectives for inclusion

The green structure is situated within an accessible public space, inviting everyone to witness, experience, and explore its presence. This strategic placement brings nature-based solutions closer to individuals and underscores the significance of implementing solutions of varying scales—small, medium, and large—in areas where people reside, work, and frequent within cities.
Moreover, throughout the pilot project, we conducted an extensive participation survey to gather feedback about the solution's efficacy. Additionally, we conducted a comprehensive mapping of locations where people expressed interest in having similar structures. This evaluation aimed to ascertain the specific needs and preferences surrounding such solutions within communities.
The modular green wall stands as an accessible solution for cities and urban stakeholders seeking to enhance well-being and livability by incorporating such structures into their environments.

Results in relation to category

The Modular Green Wall's impact lies in its holistic use of nature-based solutions, which enhance urban areas by improving soundscapes, fostering well-being through nature connection, supporting biodiversity, and providing social meeting spaces. Its success encourages stakeholders to expedite city greening efforts and integrate green solutions like the one we have implemented into various urban projects. Moreover, empirical data reinforces its impact: the demonstrated reduction of traffic noise underscores its functional value while enriching our urban landscape with beauty and vitality.

Furthermore, the testing of such solutions promotes a culture of experimentation in cities, facilitating faster adoption of new solutions through real-life testing. The substantial support for biodiversity, as evidenced by pollinator counts and the visual presence of bees, bumblebees, butterflies, and other insects, inspires citizens, planners, and designers to advocate for further actions and direct connections to urban nature.

The inclusive and participatory testing and evaluation processes have empowered everyone to voice their opinions and share their urban space preferences - and base their opinions and views on first hand experience.
For the solution providers, Parkly and Innogreen, this project has served as a pivotal moment to test, refine, and offer the solution to other stakeholders committed to enhancing the social, green, and livable aspects of their cities. The Modular Green Wall's structural adaptability and its consequential impact call for enduring transformations, influencing the planning of our cities.

How Citizens benefit

Aligned with the New European Bauhaus principle of citizen-centric benefits, the solution is designed to be accessible to all, contingent upon its specific locations. In Helsinki's pilot project, the modular green wall found its place at the heart of the city, positioned on a public square. This deliberate placement ensured universal access, enabling everyone to intimately experience the advantages of the green structure firsthand.

The project's objectives were transparently communicated to the public, encouraging their active participation by inviting feedback for continual enhancement of the solution. Additionally, we gathered location suggestions to further promote the development of similar solutions in various settings, including other street environments, underutilized urban spaces, and spaces focused on well-being and health, such as hospitals. This endeavor actively champions the necessity for more nature-based solutions and increased greenery within urban landscapes.

Moreover, to better understand the impact and usage patterns, we conducted interviews and closely observed the utilization of the space, aligning our efforts with the principles of community engagement and citizen-centered design advocated by the New European Bauhaus initiative.
