标准180是在美国空调承包商ASHRAE和ACCA的合作下制定的。其目的是解决公众可能暴露在室内环境中的商业、机构和其他建筑中，在检查和维护HVAC系统时经常不一致的做法。如今，这类建筑的现行做法大相径庭。许多设施选择遵循严格的政策，将系统保持在新的或接近新的状态。其他人要么缺乏这方面的政策，要么采取了从运行到故障的方法，只有在出现故障时才对系统或系统组件进行处理。注:本标准特别关注维修对乘员热舒适性、室内空气质量和能源效率的影响。 为了保护HVAC资本投资和/或最大限度地减少系统停机时间，与设备可靠性、设备稳健性和最大限度地降低总体维护成本有关的辅助维护问题也是适当的。然而，这些问题不在本标准的范围内。本文件的西班牙文译本目前仅在2008年版中提供。

Standard 180 was created in a collaborative effort between ASHRAE and ACCA, the Air Conditioning Contractors of America. Its intent is to address the often inconsistent practices for inspecting and maintaining HVAC systems in commercial, institutional and other buildings where the public may be exposed to the indoor environment. Current practices in such buildings vary widely today. Many facilities choose to follow rigorous policies that maintain the system in new or nearly new condition. Others either lack policy in this area or have adopted a run-to-failure approach where the system or components of the system are attended to only when there is a failure.NOTE:This standard is specifically focused on the impacts of maintenance on occupant thermal comfort, indoor air quality and energy efficiency. Ancillary maintenance issues related to equipment reliability, equipment robustness and minimizing overall maintenance costs are also appropriate in order to protect the HVAC capital investment and/or minimize system downtime. These issues, however, are outside of the scope of this standard.The Spanish translation of this document is currently available in the 2008 edition only.
