在设计阶段，需要能够预测由建筑结构、供暖系统和室外气候的给定组合产生的室内热气候。有几个大型计算机程序可用于预测热负荷和冷负荷、室内空气温度、表面温度和湿度，但这些程序通常困难且昂贵，主要用于大型建筑。本文提出了一种在设计阶段评价室内热环境的简化计算方法。新的北欧建筑法规指南中提出了这种方法。该方法的参数包括工作温度、地板表面温度和辐射温度不对称性，计算这些参数，然后与可接受热环境的现有限制进行比较。通过实例说明了该方法可以方便地进行手工计算。 本文还提出了新的北欧指南中规定的可接受热环境的要求。引文:研讨会，ASHRAE交易，1983年，第89卷，pt。华盛顿特区2B。

At the design stage, it is desirable to be able to predict the indoor thermal climate that will result from a given combination of building construction, heating system, and outdoor climate. Several large computer programs can be used to predict heating and cooling loads, indoor air temperatures, surface temperatures, and humidity, but these programs are often difficult and expensive and are used mainly for large buildings.This paper presents a simplified calculative method to evaluate the thermal indoor environment at the design stage. The method is proposed in the new Nordic Guidelines for building regulations. The parameters of this method are operative temperature, floor surface temperature, and radiant temperature asymmetry, which are calculated and then compared with existing limits for an acceptable thermal environment. The procedure, which can be performed easily by hand calculations, is demonstrated by examples.The paper also presents the requirements for an acceptable thermal environment, which are specified in the new Nordic Guidelines.
