摘要
了解建筑能耗现状,是开展建筑节能工作的基础。面对种类繁多、数量巨大的建筑物,为了使调查数据具有代表性,建议采用统计学原理进行调查。就调查方式、抽样方法和样本容量的计算进行了探讨。利用模拟结果代替试验抽样数据,得到了样本容量与建筑总量的变化关系,为样本容量的计算提供了帮助。
Knowing the real status of building energy consumption is the foundation of energy saving. For various kinds and great number of buildings, applying statistics theory would make data representational. Investigates the survey manner, sampling method and calculation of sample size. Using simulation result as a substitute for data of test sampling, obtains the relation between sample size and sum of buildings, and it would be helpful to calculation of sample size.
