美国绿色建筑委员会（US Green Building Council）的现有建筑LEED（LEED-EB）评级体系依赖于ASHRAE制定的若干标准和程序。一些是众所周知的，如ASHRAE标准62.1-2007通风率程序，但需要在不同的情况下应用，而不是在过去。在LEED-EB引入之前的几年里，ASHRAE商业建筑能源审计程序等其他程序鲜为人知。“ASHRAE一级”和“ASHRAE二级”能源审计等术语现在已在建筑行业普及。本文将讨论依赖这些ASHRAE工具和资源的LEED-EB要求，并讨论工程师在各种现有建筑场景下正确应用的挑战。 它将解释ASHRAE资源文件中提出的相关概念和定义，并介绍如何在LEED-EB认证过程中最有效地利用这些ASHRAE资源的策略。引文:内华达州拉斯维加斯ASHRAE会议论文

The US Green Building Council's LEED for Existing Buildings (LEED-EB) rating system relies upon several standards and procedures developed by ASHRAE. Some are well known, such as the ASHRAE Standard 62.1-2007 Ventilation Rate Procedure, but need to be applied under different circumstances than they have typically been in the past. Others, such as ASHRAE Procedures for Commercial Building Energy Audits, were lesser known several years ago, before LEED-EB was introduced. Such terms as "ASHRAE Level I" and "ASHRAE Level II" Energy Audits have now been popularized in the building industry. This paper will address the LEED-EB requirements that rely on these ASHRAE tools and resources and discuss the challenges to the engineer regarding proper application under various existing building scenarios. It will explain the pertinent concepts and definitions as presented in the ASHRAE resource documents, and present strategies for how these ASHRAE resources can most effectively be utilized in the LEED-EB certification process.
