Assessing the influence of legal constraints on the integration of renewable energy technologies in polygeneration systems for buildings

Hybrid polygeneration systems offer a great opportunity to meet growing energy demands with cost efficiency and environmental benefits. The identification of the optimal solution (configuration operational strategy) is strongly affected by relationship between system its surroundings. Previous studies have analyzed influence boundary conditions on synthesis for buildings. However, local regulations are often disregarded or oversimplified in those studies. Therefore, this paper aims evaluate legal integration renewable technologies A comprehensive model developed, including different types conditions, such as power exchange modalities, subsidies/surcharges prices investment costs, total ban fossil fuels. Then, applied case study Brazilian hospital. current net metering scheme implemented. Results show that natural gas cogeneration an attractive cover hospital's without possibility selling/exporting electricity. Also, scheme, itself, not enough ensure deployment. An in-depth discussion about would promote reported recommendations made how policies can be improved, need explicitly address technologies, application minimum fractions, role heat/cooling. While considers specific circumstances Brazil, it provides insights extended other countries applications. • Synthesis hybrid Influence constraints technologies. Power subsidies/surcharges, fuel considered. Technical, economic, analysis hospital study. did
