Net-zero energy communities at Local Climate Zones: integrating photovoltaics and energy sharing for a social housing neighborhood

Abstract

Integrating renewable energy systems into urban neighborhoods is essential for achieving sustainable development and decarbonization. This study investigates the integration of building-integrated photovoltaics and energy-sharing mechanisms to achieve net-zero energy communities in low-income urban neighborhoods. Using a social housing neighborhood in Ioannina, Greece, within Local Climate Zone 6, as a case study, we evaluated energy performance through hourly simulations. Annual PV generation (1096.2 MWh) exceeded the total load (931.5 MWh), achieving net-positive energy status. Incorporating a 1000 kWh battery energy storage system improved the hourly load match from 39.1 to 81% and reduced grid imports and exports by 52% and 37%, respectively. The findings underscore the potential of energy-sharing systems to enhance urban energy resilience and self-sufficiency. In addition, the study emphasizes the importance of leveraging Local Climate Zone characteristics to design energy systems tailored to urban contexts. Policy incentives and further research are recommended to promote cost-effective energy-sharing models in similar contexts.
