The Rechargeable Landscape Powering Sustainable, Resilient Housing with Nature-Based Systems

This forum proposes a paradigm shift: landscape architecture as the foundational operating system for sustainable housing. We advocate for moving beyond green space as an amenity, to designing integrated landscape systems that actively regenerate ecological functions, close resource loops, and enhance long-term community viability. Our objective is to provide a framework where edible landscapes, energy-positive systems, smart technology, and green finance converge to create housing that is inherently resilient, restorative, and aligned with planetary boundaries. The session will be structured around four interlocking pillars of sustainable housing that form a value chain from technical design to financial viability: Pillar 1: Edible Landscapes for Direct Community Resilience. We will showcase how integrating productive farms and edible planting into housing estates transforms recreational space into critical infrastructure for food security and social cohesion, including models for community-managed food safety. This localized food systems reduces carbon footprints, manage organic waste through composting, and strengthen socio-ecological bonds. Pillar 2: The “Rechargeable Landscape”: Energy and Ecological Regeneration. We explore how landscapes can be designed as net-positive ecological infrastructure: how urban forests function as carbon banks for credit generation, how blue-green infrastructure provides passive cooling to slash energy bills, and how landscape biomass can feed circular bioenergy systems. This transforms housing sites from resource consumers into regenerative nodes. Pillar 3: Technology for Verification & Ecosystem Service Optimization. We showcase how AI and IoT sensors (exemplified by our research on assessing roadside trees in Hong Kong from both suitability and sustainability aspects) provide critical data to quantify ecosystem services (carbon, cooling, biodiversity), ensure system health, and maximize the environmental performance of these living infrastructures. Pillar 4: Green Finance & Standards for Mainstream Adoption. We discuss enabling frameworks to scale sustainability, including “Landscape Performance Bonds” that securitize verified ecosystem services, and the potential for a “Regenerative Community” certification to set benchmarks and attract investment towards truly sustainable housing models.
