Summary
Buildings are responsible for a remarkable portion of the energy consumption of global energy consumption and carbon emissions. Reducing dependence on fossil fuels, improving energy efficiency, and mitigating environmental impacts in the building sector have become increasingly critical. Solar energy, as a clean and renewable resource, has demonstrated remarkable potential in building energy conservation through photovoltaic and thermal utilization. However, single photovoltaic or thermal technologies alone can no longer meet the long-term and diversified energy demands of buildings. Solar cogeneration systems, which simultaneously generate electricity and thermal energy by effectively harnessing solar energy, provide an advanced and efficient pathway for achieving low-carbon and sustainable development in buildings.
This Special Issue aims to collect and publish the latest research findings and review papers on solar cogeneration technologies for building energy conservation. The Special Issue will focus on research areas such as photovoltaic/thermal (PV/T) systems, solar-driven Organic Rankine cycles (ORC) systems, and solar heating and cooling systems. Multidisciplinary studies covering system design, modeling and optimization, innovative heat transfer and energy storage materials, and techno-economic evaluations for building applications. We sincerely welcome contributions that advance the research and practical application of solar cogeneration systems in modern building energy systems.
Topics of interest include, but are not limited to:
· Building-Integrated solar photovoltaic/thermal systems
· Solar-driven Organic Rankine cycle systems
· Solar heating and cooling systems
· Solar-assisted heat pump systems
· Solar thermal storage technologies
· Distributed and centralized solar energy systems
· Enhanced heat transfer technologies for solar energy collection
