IFLA Joins the WGIN Working Group on Post-Conflict Reconstruction

The International Federation of Landscape Architects (IFLA) has joined the WGIN Working Group on the reconstruction of post-conflict areas. Representing IFLA in this initiative is Dr. Maria Gabriella Trovato, an Associate Professor in the Department of Landscape Architecture at the Norwegian University of Life Sciences (NMBU) and the Program Leader of the International Master’s Program in Landscape Architecture for Global Sustainability. Dr. Maria Gabriella Trovato is a distinguished expert in landscape planning, spatial development, and the reconstruction of territories affected by conflicts and environmental crises. She has extensive experience in integrating nature-based solutions into the restoration of urban and natural landscapes. She is the Founder and Director of the Eastern Mediterranean Landscape Observatory (EMLO), a member of the UNISCAPE Executive Board, and the Chair of Landscape Architects Without Borders (IFLA). Her research focuses on landscape restoration in emergency contexts, urban adaptation to climate change, and the development of inclusive and resilient public spaces. The participation of IFLA in this working group represents a strategic step toward embedding nature-based solutions into the reconstruction of post-conflict territories. With the number of regions affected by armed conflicts and socio-political upheavals increasing globally, the demand for sustainable and resilient reconstruction strategies has never been more urgent. A holistic approach—combining ecological restoration, climate resilience, and social reintegration—is essential to ensuring long-term stability and quality of life for affected communities. The collaboration between WGIN and IFLA aims to foster innovative strategies for land restoration, establish long-term planning frameworks, and contribute to the creation of sustainable and resilient urban environments. As post-conflict reconstruction becomes an increasingly critical global challenge, integrating landscape architecture and nature-based solutions into recovery efforts is paramount for achieving sustainable development. We invite organizations to collaborate in the development of innovative solutions for post-conflict territory restoration.

Løren School Leads the Way in Green Roof Solar Innovation

© Sempergreen Services and BrightView Løren Elementary School in Oslo has taken a significant step toward sustainability by integrating solar energy technology with its existing green roof. The challenge was to install solar panels while preserving the biodiversity and structural integrity of the roof. Thanks to a collaboration between Sempergreen and Over Easy Solar, an innovative solution was implemented: lightweight vertical PV units that enhance energy output without compromising the Sedum roof. This groundbreaking renovation sets a new standard for urban sustainability. Advancing Sustainable EducationWith 750 students, Løren Elementary School prioritizes environmental responsibility. In 2022, the school aimed to advance its sustainability efforts by transforming its green roof into an energy-generating ecosystem. The goal was to maintain biodiversity while harnessing solar power, ensuring a functional and eco-friendly learning environment. Overcoming Challenges with Smart DesignThe biggest hurdle was finding a lightweight solar solution that seamlessly integrated with the existing Sedum roof while staying within the building’s load-bearing limits. The school needed a system that preserved the greenery’s quality, efficiently produced energy, and utilized cutting-edge technology.Løren School is now a role model for urban sustainability, demonstrating that solar energy and rooftop biodiversity can coexist. Sempergreen & Over Easy Solar’s Unique ApproachIn partnership with Over Easy Solar, Sempergreen provided a lightweight, prefabricated VPV system specifically designed for green roofs. This innovation not only facilitated smooth integration but also enhanced the performance of both the Sedum vegetation and the solar panels. How the System Works Vertical Double-Sided Solar Panels: Capture sunlight from both sides, maximizing energy production. Cooling & Reflective Effects: The Sedum roof cools the panels, while its reflective properties (albedo effect) boost efficiency. Biodiversity Protection: The system ensures the green roof remains healthy and functional under the panels. Project Highlights Smart Synergy: The Sedum roof enhances solar panel performance while thriving beneath the PV units. Lightweight & Load-Friendly: The system weighs only 51 kg/m² when fully saturated, ideal for weight-sensitive structures. Fast & Easy Installation: Ballast-free design allows quick assembly without mechanical fastenings. Scalability & Growth: Following the successful 2022 pilot, the project expanded in 2023, reaching 46 kWp across 500 m². Urban Sustainability Model: A leading example of how cities can integrate green roofs and renewable energy. Delivering Energy-Efficient ResultsThe combination of green roofs and vertical PV panels has produced impressive results. The 2022 pilot demonstrated high energy yields, and surprisingly, the quality of the green roof improved beneath the panels compared to uncovered sections. Encouraged by these outcomes, the school expanded the project in 2023, solidifying its commitment to sustainability. The unique VPV system from Over Easy Solar optimizes energy production by balancing output throughout the day, reducing CO₂ emissions, and increasing overall efficiency. Løren School’s green roof solar project is a shining example of how urban spaces can embrace sustainability without compromise, leading the way for future innovations.

Briefing for MEPs | Making European Cities more Resilient through Urban Green Infrastructures

The European Chapter of the WGIN is publishing a new policy briefing entitled “Making European Cities more Resilient through Urban Green Infrastructures”. The paper intends to explain the challenges cities are facing and will be increasingly confronted with as a result of extreme weather events and how to support their adaptation to climate change. In that context, this briefing demonstrates how urban green infrastructures, namely green roofs and walls, are key solutions to enable an increased resilience of urban areas while providing many accompanying benefits for their inhabitants such as stormwater management, the restoration of biodiversity in cities, reducing pollutants’ concentrations and increasing residents’ wellbeing. Concrete examples are provided to showcase these benefits. The briefing also explains why urban green infrastructures are central for several upcoming EU initiatives, in particular the European Climate Adaptation Plan and the European Water Resilience Strategy, and provides a few suggestions to boost the deployment of urban green infrastructures in the new EU political mandate.
