| dc.title | Heating and cooling energy sharing within a zero-emission district (including commercial and residential buildings) | en_US |
| dcterms.abstract | This study presents a TRNSYS-based simulation framework to optimize renewable energy sharing in a mixed-use Zero-Emission District (ZED) in coastal Hong Kong. A total of 256 configurations were analyzed to assess the impact of energy sharing mechanisms, solar-wind energy mix ratios, and storage capacities on technical, economic, and environmental performance. | en_US |
| dcterms.abstract | Results show that implementing an 800 kWh centralized storage system and energy sharing control significantly improved on-site energy utilization, with OEM and OEF increasing by over 15% and WMI exceeding 0.70 in most cases. The optimal economic performance occurred at a moderate storage capacity (three battery units), while wind-dominant configurations achieved the best carbon reduction outcomes. | en_US |
| dcterms.abstract | Balanced PV/wind mixes (40%-60%) yielded the most consistent results across all indicators. The study demonstrates that coordinated energy sharing and hybrid renewable integration can greatly enhance the sustainability and efficiency of ZEDs in dense urban environments. | en_US |
