本文描述了一种旨在分析气候条件与生物气候舒适度感知之间关系的方法的应用。这项实验包括在里斯本一个开放的城市地区进行两个阳光明媚的春天里同时进行的问卷调查和天气测量。结果表明，在室外条件下，当温度远高于室内条件的标准值时，可以保持热舒适性。每当超过31摄氏度的生理等值温度门槛时，衣服似乎就会自发适应。对气温的感知很难从对热环境的感知中分离出来，并受到其他参数的影响，尤其是风。对太阳辐射的感知与从不同方向(即落在垂直和水平表面上)的通量的强度有关，由入射到人体的系数加权。风被发现是最容易被察觉的变量，通常是负面的。对风的感知在很大程度上取决于风速和风变率的极值。女性对高风速的负面反应比男性更强烈。实验证明，这种方法非常适合于实现所提出的目标，并且可以应用于其他领域和其他季节。
This paper describes the application of a methodology designed to analyse the relationship between climatic conditions and the perception of bioclimatic comfort. The experiment consisted of conducting simultaneous questionnaire surveys and weather measurements during 2 sunny spring days in an open urban area in Lisbon. The results showed that under outdoor conditions, thermal comfort can be maintained with temperatures well above the standard values defined for indoor conditions. There seems to be a spontaneous adaptation in terms of clothing whenever the physiological equivalent temperature threshold of 31°C is surpassed. The perception of air temperature is difficult to separate from the perception of the thermal environment and is modified by other parameters, particularly wind. The perception of solar radiation is related to the intensity of fluxes from various directions (i.e. falling upon both vertical and horizontal surfaces), weighted by the coefficients of incidence upon the human body. Wind was found to be the most intensely perceived variable, usually negatively. Wind perception depends largely on the extreme values of wind speed and wind variability. Women showed a stronger negative reaction to high wind speed than men. The experiment proved that this methodology is well-suited to achieving the proposed objectives and that it may be applied in other areas and in other seasons.
