Energy Saving and Carbon Reduction Schemes for Hospital with Photovoltaic Power Generation and System Upgrading Technology

In order to help China achieve the "double carbon" goal of achieving the overall carbon peak and the high quality and sustainable development of the economy, and to enrich the work and content of energy saving and emission reduction in the building sector, a feasibility study was conducted for the most complex and energy-consuming hospital as a key project for energy saving and carbon reduction. The feasibility study was carried out by designing a photovoltaic power generation and upgrading the existing systems (including air conditioning, hot water system and intelligent control system), taking into account the local climate characteristics. The results show that after the implementation of this system, the energy saving and carbon reduction effect of the project is obvious, and the annual electricity saving of the hospital is expected to reach 1987.486 MWh, which is 14% more than the energy saving rate before the renovation, and the direct saving of electricity cost is 2.077 million RMB, and the reduction of carbon dioxide emission is 1212.666 tonnes. The carbon dioxide emission reduction of the photovoltaic power generation system in this project is 86.559 tonnes, which can be promoted and popularised in the field of energy saving and carbon dioxide reduction. To provide a useful reference for energy-saving and environment-friendly building design.
