摘要

公共建筑是能源密集型用户,特别是在缺乏能源管理的情况下。为了提高能源自给自足,取代化石燃料的使用,降低能源费用和温室气体排放,在建筑物中使用能源效率战略和可再生能源(RES)比以往任何时候都更成为摩洛哥的国家优先事项。关于摩洛哥政府在能源效率和可持续发展方面的典范,该研究支持该目标,并提供了对摩洛哥20多所大学校园的深度能源绩效分析的结果,该分析得出的结论是,大学校园中约80%的能源消耗用于闪电和卫生热水。随后,本研究考察了考虑到使用现场太阳能,实施减少电网能源需求的行动的节能潜力和环境效益。随后,本研究旨在分析可再生能源整合在公立大学校园中的影响,即光伏发电(ESM1)和太阳能热系统(ESM2)用于发电和热水使用,以评估技术经济环境绩效对建筑能耗的降低。因此,本文通过整合两种节能措施(ESM),对校园进行了详细的能量经济和环境(3E)分析模拟。结果表明,集成ESM1系统可使年能源需求降低22%,能源账单降低34%,而集成ESM2系统可实现67%的节能。根据结果分析,ESM1的整合预计在所有校区的30222 MWh和ESM2的2559 MWh的基础上,每年节省6044 MWh的电能,相当于284 m3/年的柴油。随着能源消耗的减少,可以减少用于发电的化石燃料,每年抵消672吨二氧化碳的温室气体排放。此外,评价结果表明,能源性能指标从530 kWh/bed/yr降低到248 kWh/bed/yr,节能56%。

Energy saving potential diagnosis for Moroccan university campuses
Public buildings are energy-intensive users, especially when energy management is lacking. More than ever, the use of energy efficiency strategies and renewable energy sources (RES) in buildings are a national priority for Morocco in order to improve energy self-sufficiency, replace fossil fuel use and lower energy bills and greenhouse gas emissions. Relating to the exemplarity of the Moroccan government in terms of energy efficiency and sustainable development, the study support that aim and presents results of a deep energy performance analysis of more than 20 university campuses across Morocco, which has concluded that around 80% of the energy consumed in the university campuses is designated for lightning and hot water for sanitary use. Later, this study examined the potential for energy saving and the environmental benefits of implementing actions to reduce energy demand from the grid, considering the use of on-site solar energy. Thereafter, the study aimed to analyze the impact of RES integration in public university campuses, namely the photovoltaic (ESM1) for electricity output and solar thermal system for hot water use (ESM2), to assess the techno-economic-environmental performance on building energy consumption reduction. Hence, the paper reported a detailed energetic-economic and environmental (3E) analysis simulation for campuses by integration of the two Energy Saving Measurements (ESM). The results showed that the integration of ESM1 system can reduce the annual energy demand by 22% and the energy bill by 34%, whereas the integration of ESM2 achieved 67% in energy saving. According to the analysis of the results, the integration of ESM1 is expected to save 6044 MWh of electrical energy annually on the 30222 MWh for all campuses and 2559 MWh for ESM2 which is equivalent to 284 m3/yr of diesel. With the reduced energy consumption, it is possible to cut down fossil fuels for electricity production and offset greenhouse gas emissions by 672 tons of carbon dioxide annually. Besides, the evaluation of results showed that the energy performance indicator was reduced from 530 kWh/bed /yr to 248 kWh/bed/yr, which represents 56% of energy saving.
