在未来的气候变化中，建筑设计师可能需要向客户证明他们的建筑物在未来的天气条件下将继续提供舒适的环境。建筑物模拟模型可用于这一目的，前提是可以构建合适的天气文件。本文介绍了使用UKCIP（UKCP09数据）的最新气候预测和构建以下参数的每小时天气文件的方法：干球温度，相对湿度，云量，太阳辐射（直接和散射），风速和风向。对于给定的未来情景，所使用的方法首先从3000年的UKCP 09数据中选择适当的月份来构建测试参考年（TRY）。不幸的是，UKCP 09每小时的数据没有风或云的数据，太阳辐照度是在低太阳角度未校正。本文描述了从UKCP09数据计算风速和云量的算法。根据这些数据，可以构造TRY并将其格式化为适合与常用的模拟包一起使用。实际应用：建筑专业人士越来越多地寻求保证，一个拟议的建筑将如何表现在未来，而不是历史气候。本文介绍了一种处理最新的未来气候预测（UKCP09数据发布于2009年6月），并生成一个测试参考年（TRY）的方法，该方法包含适用于常用建筑物模拟程序的完整天气参数。
In the future with climate change, building designers may need to demonstrate to clients that their buildings will continue to provide a comfortable environment under future weather conditions. Building simulation modelling can be used to this end provided that suitable weather files can be constructed. This article describes the use of the latest climate projections from UKCIP (UKCP09 data) and a method of constructing an hourly weather file for the following parameters: dry-bulb temperature, relative humidity, cloud cover, solar irradiation (direct and diffuse), wind speed and wind direction. For a given future scenario, the approach used first selects appropriate months from 3000 years of UKCP09 data to construct a Test Reference Year (TRY). Unfortunately, the UKCP09 hourly data has no wind or cloud data, and the solar irradiance is uncorrected at low sun angles. This article describes algorithms for calculating wind speed and cloud cover from the UKCP09 data. From this data, a TRY can be constructed and formatted to be suitable for use with commonly used simulation packages. Practical applications: Building professionals increasingly seek reassurance on how a proposed building will perform under a future rather than historical climate. This article describes a method of processing the latest future climate projections (UKCP09 data released in June 2009) and generating a Test Reference Year (TRY) with the full complement of weather parameters suitable for use by commonly used building simulation programmes.
