为了提供有关气候变化的信息，英国气候影响计划（UKCIP）为英国提供了分辨率为5平方公里网格的最新UKCP 09数据。这些数据集被用于本研究沿着与历史测量数据的两个位置-布拉克内尔（伦敦）和爱丁堡-批判性地分析可能发生的变化，可能会发生在太阳-空气温度和日光照度配置文件。这些参数对建筑物和建筑设备的设计和功能有重要影响。预测数据集的溶胶-空气温度的急剧增加。爱丁堡和布拉克内尔的深色表面的太阳-空气温度分别增加了20.1 °C和13.3 °C。这些增量可能是由于用于计算太阳-空气温度的组成变量（即太阳辐射、风速和干球温度）变化的复合效应。进行了敏感性测试，以了解每个变量对溶胶-空气温度的影响。在数据集中也发现了日光增加的趋势。这是由于天空条件的清晰度变化。预测表明，太阳气候的特征发生了根本性的变化，即从目前的总辐射的0.37的漫射部分，这表明轻度混浊下降到0.13，表明晴朗的天空，异常低的混浊度。
To provide information on climate change, the UK Climate Impacts Programme (UKCIP) provided the latest UKCP09 data to a resolution of 5 km square grids for the UK. Those data sets were used in this study along with the historical measured data for two locations—Bracknell (London) and Edinburgh—to critically analyse the likely changes that may occur in the sol-air temperature and daylight illuminance profiles. These parameters have an important bearing on the design and function of buildings and building services. Drastic increment of sol-air temperature was found for the projected data sets. An increase of as much as 20.1 °C of sol-air temperature for dark-coloured surface was found for Edinburgh and 13.3 °C for Bracknell. These increments may be due to the compound effect of change in the constituent variables that are used to calculate sol-air temperature, i.e. solar radiation, wind speed and dry bulb temperature. A sensitivity test was carried out to see the effect of each variable on sol-air temperature. An increasing trend of daylight was also found in the data sets. This is attributed to the changing clarity of the sky condition. The predictions indicate a radical change in the characteristics of solar climate, i.e. from the present diffuse fraction of total irradiation of 0.37 which indicates mild turbidity to a drop of 0.13 indicating clear skies with exceptionally low turbidity.
