This paper assesses the current level of the application of passive/natural and daylighting systems in the US by architects and engineers. Although an extensive list of publications about passive/natural and daylighting systems exists, there are very few studies addressing the degree of applying these systems in practice. This paper, through the application of a survey methodology, evaluates the level of the application of passive and daylighting systems in the US and discusses the survey findings and variables that may increase the application of these systems in practice. The findings indicate a low level of the application of passive systems that need complex designs. In this case, daylighting systems were more regularly applied, while the application of passive cooling in the US was more common than passive heating systems. To promote the application of passive systems, the clients’ desire/collaboration, building code/rating systems, and simulation tools for passive design were the most influential factors according to the survey findings. The focus of this study was on the application of passive systems as a part of a larger research focused on the application, education, and best-practices of passive design in the US.

本文评估了建筑师和工程师在美国被动/自然和采光系统的当前应用水平。尽管存在大量有关被动/自然和采光系统的出版物，但是很少有研究涉及在实践中应用这些系统的程度。本文通过调查方法的应用，评估了美国被动和采光系统的应用水平，并讨论了调查结果和变量，这些变量和变量可能会增加这些系统在实践中的应用。研究结果表明，需要复杂设计的无源系统的应用水平较低。在这种情况下，日光照明系统被更经常地应用，而在美国被动冷却的应用比被动加热系统更为普遍。为了促进无源系统的应用，根据调查结果，客户的需求/协作，构建代码/评估系统以及用于无源设计的仿真工具是最有影响力的因素。这项研究的重点是无源系统的应用，这是一项针对美国无源设计的应用，教育和最佳实践的大型研究的一部分。
