【摘要】 对中国移动山东公司办公楼改造，对办公楼的围护结构节能改造、天然采光和自然通风优化、热舒适性及可再生能源利用展开探讨。围护结构节能改造方面，外墙增设内保温，玻璃幕墙采用5+15Ar+5Low-E型；为优化天然采光效果，在南侧增设水平遮阳板，西侧和东侧采用折线型垂直遮阳板，进而提高采光的均匀性；合理布置规划开启扇的位置，最大限度地利用自然通风条件；在屋顶和南侧的水平遮阳板上设置光伏板，以充分利用太阳能。通过模拟计算对比改造前后的能耗、舒适性等数据来验证绿色改造效果策略，改造后建筑综合电耗节能率达到28.38%,建筑室内空间全年动态采光达标率为100%。通过CFD模拟对室内气流组织进行分析，确认气流组织合理，建筑室内房间热湿环境指标PMV和PPD达到整体II级标准，光伏组件系统效率为81.8%。研究对于推动既有建筑的节能减排和绿色发展具有一定的意义和价值。更多还原

【Abstract】 For the retrofit design of the office building of China Mobile Shandong Company, the energy-saving retrofitting of the office building’s envelope, optimization of natural lighting and natural ventilation, thermal comfort, and the use of renewable energy are discussed. Energy-saving enclosure transformation covers: the external wall is added with internal heat preservation; glass curtain wall selects the type of 5+15Ar+5Low-E. In order to optimize the natural lighting, the horizontal sunshade is added on the south side, and the folding vertical sunshade is added on the west and east side to improve the uniformity of lighting; reasonable arrangement of open-fan position will maximumly use of natural ventilation conditions; photovoltaic panels are set for the horizontal sunshade on the roof and the south side will fully utilize solar energy. The energy consumption and comfort data before and after the retrofit are compared through simulation calculations to verify the feasibility of the green retrofit strategy. After the retrofit, the comprehensive energy saving rate of the building reaches 28.38% in terms of electricity consumption, the year-round dynamic lighting rate of the building’s indoor space is 100%. The CFD analysis of indoor airflow organization confirms that the airflow organization is reasonable, the indoor room thermal and humidity environment indexes of the building, PMV and PPD, reach the overall Class II standard, and the efficiency of the PV module system is 81.8%. The study has certain significance and value for promoting energy conservation, emission reduction and green development of existing buildings.更多还原
