室外空间使用的决定因素之一是人们对热舒适的体验。热指数的范围很广。然而，以往对阿根廷门多萨大都市区的研究表明，国际传播的6项热舒适指标的预测能力小于25%。这种高反差表明，需要提出一种适应性模型来预测适应人口对这个干旱气候的“绿洲城市”的热舒适条件。为此，在冬季和夏季对小气候参数进行了监测，并对步行街上人们的感知进行了实地调查。进行了14次多元线性回归，并采用赤池信息准则进行模型选择。为此，建立了“干旱区城市热舒适指数（IZA）”模型。该公式考虑了空气温度、相对湿度和风速，它们都是重要的、相互独立的、现成的变量。我们发现，IZA的预测能力为73%，证明了所提出模型的有效性。设计师和城市规划者可以使用IZA作为一个简单而有用的工具来改善户外空间的设计。(C) 2014 Elsevier Ltd.版权所有。
One of the determining factors for the use of outdoor spaces is the experienced thermal comfort by people. There is a wide range of thermal indices. However, previous studies in Mendoza Metropolitan Area, Argentina, revealed that the predictive ability from six thermal comfort indices of international spread is less than 25%. This high contrast reveals the need for proposing an adaptive model to predict the thermal comfort conditions of the adapted population to this "oasis city" of arid climate. For this purpose, monitoring of microclimatic parameters and field surveys about the perception of the people on a pedestrian street were carried out in both winter and summer. Fourteen Multiple Linear Regressions were performed and the Akaike's information criterion was used to the model selection. As a result, a new model has been developed: the "Thermal comfort Index for cities of Arid Zones (IZA)". The formula considers air temperature, relative humidity and wind speed, all significant, independent each other and readily available variables. We found that the IZA's predictive ability is 73%, demonstrating the efficiency of the proposed model. Designers and urban planners may use the IZA as a simple and useful tool to improve the design of outdoor spaces. (C) 2014 Elsevier Ltd. All rights reserved.
