Abstract
Building-integrated rooftop greenhouses address global agricultural challenges of climate change,
energy crisis, and food security. Urban agriculture systems with rooftop greenhouses offer sustainable
food production solutions in urbanized cities. These systems demonstrate technical advantages through
waste energy utilization, economic benefits from reduced distribution costs, and social benefits as community
spaces. The greenhouse-building integration enables efficient energy exchange, resulting in a reduction of building
energy loads by up to 19% annually and a decrease in greenhouse energy consumption by 12%. This system
also minimizes carbon emissions through shortened distribution processes and improved energy management.
Energy exchange between buildings and greenhouses optimizes crop growth conditions while utilizing building waste
heat and carbon dioxide. This integration could enhance urban food security while potentially improving building
energy efficiency and environmental sustainability in urban environments.
Keywords: climate change, energy efficiency, food security, greenhouse integration, urban agriculture
