建筑是为特定的气候而设计的，但它们的寿命通常为100年。由于全球变暖的影响，气候变化可能要求建筑物在一系列气候条件下运行。目前用于设计目的的许多气候数据都是大约30年前的，这一事实使这种影响更加复杂。本文通过研究温度和太阳辐射变化对一个特定设计变量——能源使用的具体影响，研究了过去二十年来气候变化对建筑设计和性能的影响。结果表明，英国伦敦地区的温度和太阳辐射在过去15年中发生了显著变化，目前用于能源设计计算的气候数据导致能源使用预测的不准确性高达17%。然而，有证据表明，暖冬的一部分好处可能是提高了舒适度，而不是减少了能源消耗。结论是，这些计算中使用的气候数据应该紧急审查，因为它们可能是主要设计者采用不适合未来使用的解决方案。
Buildings are designed for a specific climate, yet they often have a lifetime of 100 years. Climate change may require a building to operate over a range of climatic conditions as a result of the impact of global warming. This effect is compounded by the fact that many of the climatic data currently used for design purposes are some 30 years old. This paper investigates the impact that climate change over the last two decades may have on the design and performance of buildings by examining the specific effects of changes in temperature and solar radiation on one particular design variable, energy use. The results indicate that the temperature and solar radiation in the London region of the United Kingdom have changed significantly in the last 15 years, and that the climatic data currently being used for energy design calculations lead to inaccuracies in predictions of energy use of up to 17%. However, evidence is presented which suggests that a proportion of the benefits of milder winters may be taken as improved comfort instead of reduced energy use. It is concluded that the climatic data used in these calculations should be reviewed urgently, as they may be leading designers to adopt solutions which will be inappropriate for future use.
