净零建筑能耗城区的能源规划方法
Methodology of energy planning for net zero building energy community
摘要：
净零能耗建筑是在超低能耗建筑的基础上利用可再生能源的建筑，其全年总能耗量近似等于在现场或在其他地方所生产的可再生能源。但是在规模较大的单体建筑中要实现超低能耗和利用可再生能源有很多困难，其解决办法是通过建筑群或城区层面的空间和环境资源的共享、建筑负荷的平准化实现净零建筑能耗城区。净零建筑能耗城区需要有需求侧与供应侧协同和协调的能源规划。提出了能源规划的六步法，即目标设定、资源分析、需求预测、规划协调、系统优化和绩效评估。
Abstract：
Net zero energy buildings (NZEB) utilize renewable energy sources based on ultra-low energy building technologies. NZEB’s annual total energy consumption is approximately equal to the amount of renewable energy produced on-site or elsewhere. However, there are many difficulties in achieving ultra-low energy consumption and using renewable energy in large-scale single buildings. The solution is to achieve a net zero building energy community (NZBEC) through the sharing of space and environmental resources at the level of building group or community and the leveling of construction load. NZBEC needs energy planning that is based on synergy and coordinating between the demand and supply sides. Presents a six-step approach to energy planning, namely, goal setting, resource analysis, demand forecasting, urban planning coordination, system optimization and performance evaluation.
