自1995年以来，两个主要的典型年份天气数据新来源——ASHRAE的能源计算天气年版本2（WYEC2），适用于59个美国和加拿大地点，以及NREL的典型气象年版本2（TMY2），适用于239个美国地点——已可用于建筑能源模拟。这两个数据集代表了多年来在纠正数据异常和向早期WYEC和TMY天气集添加改进的太阳模型方面所做的努力。虽然很容易将气候统计数据中的变化（例如，度日、风速、平均太阳能热增量等）制成表格并进行比较，但此类变化对建筑物模拟能耗的影响不太清楚。本研究的目的是使用DOE-2模拟原型住宅建筑，以（1）确定各种典型年份天气数据（如TMY2、TMY、WYEC2、WYEC）的能力，并尝试重现长期天气- 使用30年历史天气数据进行模拟时的长期平均加热和冷却能耗（2）比较不同典型年份数据的模拟能耗，并确定是否因天气数据类型而存在系统差异。单位:I-PCITION:研讨会，ASHRAE交易，1998年，第104卷，第2部分，多伦多

Since 1995, two major new sources of typical year weather data--ASHRAE's Weather Year for Energy Calculations, Version 2 (WYEC2), for 59 U.S. and Canadian locations and NREL's Typical Meteorological Year, Version 2 (TMY2), for 239 U.S. locations--have become available for use in building energy simulations. Both of these data sets represent several years of effort in correcting data anomalies and adding improved solar models to the earlier WYEC and TMY weather sets. Although it is straightforward to tabulate and compare the changes in climate statistics, e.g., degree-days, wind speed, average solar heat gain, etc., the impact that such changes have on the simulated energy consumption of a building is less clear. The purpose of this study is to use DOE-2 simulations of prototypical residential buildings to (1) determine the ability of various typical year weather data such as TMY2, TMY, WYEC2, WYEC, and TRY to reproduce the long-term average heating and cooling energy consumption when simulated using 30 years of historical weather data and (2) compare the simulated energy consumption from different typical year data and determine if there are systematic differences due to the type of weather data.Units: I-P
