本文讨论了一些新的节能控制方法在新的或现有结构中的实施，并得出了一些令人震惊和意想不到的结果。这些结果可能是可预测的，也可能不是可预测的，但归根结底，最初的预期并非总能实现。有时，我们对系统和控制进行更改，却没有充分了解特定更改将如何影响整个结构。此外，为了最大限度地节约能源，我们倾向于在设备和控制装置经过全面测试和评估之前应用它们。 这并不是说利用这些设备不可能节能，而是表明更好地理解驱动力及其控制至关重要。如今，许多新技术正在被用于节能:死区恒温器、优化控制、采光、开启太阳能强度的灯光、窗帘拉深的优化、建筑构件的可变热性能、固定和可变质量、优化气流以及一整套新的机械系统和组件。 难怪过去制定的传统规则不足以应对这些新概念。单是死区恒温器就改变了所有基本规则，当与其他节能设备结合使用时，它已经完全使所有已知的简单标准失效。引文:研讨会，ASHRAE交易，第87卷，第一部分，伊利诺伊州芝加哥

This paper discusses the implementation of some of the new energy-saving control methodologies in new or existing structures has developed some startling and unexpected results. These results may or may not have been predictable, but in the final analysis the original expectations were not always achieved. Sometimes we implement changes to system and controls without fully understanding how the particular changes will affect the entire structure. Also, in our attempt to maximize energy savings, we tend to apply equipment and controls before they have been fully tested and evaluated. This is not to say that energy saving is not possible by utilizing these devices, but rather it indicates that a better understanding of the driving forces and their control is essential.Many new techniques are being used today to save energy: Devices such as dead bandthermostats, optimization controls, daylighting, light switching on solar intensity,optimization of drape drawing, variable thermal properties of building elements, fixedand variable mass, optimizing air flow and a whole host of new mechanical systems andccmponents. It is no wonder that traditional rules established in the past are inadequateto deal with these new concepts. The dead band thermostat alone has changed allof the ground rules, and when coupled with other energy-conserving devices, it hascompletely invalidated all known simple standards.
