| summary |
Urban agricultural systems will be configured over the following years to respond to increasing climate change, urbanisation, and population growth. Controlled environment agriculture (CEA) is an increasing trend since it can be easily integrated into the built environment. However, this food production system requires intensive capital and energy resources, with artificial lighting as the primary contributor to its high operational impacts. New methods and tools for planning and design can provide innovative solutions for shifting urban agriculture toward sustainability. This paper addresses the food security challenge in cities by introducing a sunlight-based computational approach for indicating the agricultural possibilities of three-dimensional urban surfaces according to crop-centric environmental suitability. The procedure aims to improve CEA efficiency through a passive natural lighting optimisation strategy, indicating the sunlight thresholds for various crop species. The methodology interconnects solar radiation values measured through sunlight simulations with crops’ daily light integrals, using Singapore and Chennai (India) as case studies. The results suggest that urban areas with high solar radiation levels possess large degrees of year-round harvesting potential. This methodology can assist designers (architects, urban planners, and engineers) and local governments in strategizing urban agriculture developments and provide decision-making support for crop harvesting initiatives in cities. |
