天气数据对于基于模拟的建筑能耗研究至关重要。气象资料应反映气候变化的特征。然而，使用长期气候数据的典型气象年（TMY）的发展，可能会削弱近期气候变化的影响和相应的建筑能源响应。本文研究了近37年来香港亚热带气候资料的变化及其对模拟结果的影响。总结了太阳辐射、温度和风速的气候变化，并给出了它们的日总量、平均值、极值和/或偏差值。通过37年内不同时间和周期长度的地面测量获得的典型天气数据，确定了香港代表性建筑物的冷负荷，并将结果与年度数据进行了比较。针对气候变化条件下的建筑能耗模拟，优化了原始测量的周期（长度）和TMY的更新频率。
The weather data is essential to simulation-based building energy studies. The weather data should render the features of the changing climate. The typical meteorological year (TMY) developments using the long-term climate data, however, may weaken the impact of the recent climate change and the corresponding building energy responses. This paper studies the changes of the climate data (by ground measurements) and their impacts on the simulation results of the subtropical Hong Kong over 37 years. The climate changes for solar radiation, temperature and wind speed were summarised, and their daily total, average, extreme, and/or deviation values were presented. The typical weather data developed by the ground measurements of different times and period lengths (within the 37 years) determined the cooling load of a representative building in the Hong Kong, and the outcomes were compared to that of the yearly data. The period (length) of the raw measurements and the update frequency of TMY were optimized for the building energy simulations in the changing climate.
