该项目的目标是开发一个运行和维护（O&M）程序数据库，并记录不同的运行和维护实践对拥有和运行设备的成本以及其他相关效益的影响。这些信息将有助于开发与运维相关的教材、指南、标准和手册版本。调查了31名建筑维修专家和维修人员，以确定正确操作暖通空调设备的关键文献。制冷机、锅炉、空气处理器、冷却塔、成套屋顶设备、气动空气压缩机和食品制冷设备排名最高。 收集了超过53种HVAC/R设备的运行和维护数据，重点是高优先级设备。收集到的文件/数据类型包括制造商和供应商的手册、目录和切割单、技术书店的书籍、技术论文、期刊文章和一些业主运维程序手册。该项目的理念是汇编和组织材料，使其具有针对性、全面性和可访问性。重点是对材料进行编目，以确保用户能够访问。

The object of this project was to develop a database of operations and maintenance (O&M) procedures and documentation of the impacts that different O&M practices have on the costs of owning and operating the equipment, as well as other related benefits. The information will assist in the development of O&M related educational materials, guidelines, standards and handbook editions.A literature search was conducted and 31 building owners, operators and O&M professionals were surveyed to identify the HVAC/R equipment that experts felt was most critical to operate and maintain properly. Chillers, boilers, air handlers, cooling towers, packaged rooftop equipment, pneumatic air compressors and food refrigeration equipment were among the highest ranked. Operations and maintenance data was collected for over 53 types of HVAC/R equipment, with an emphasis on the high priority equipment. Document/datatypes collected included manuals, catalogs and cut sheets from manufacturers and vendors, books from technical bookstores, technical papers, periodical articles, and a few owner O&M procedural manuals.The project philosophy was to compile and organize the material so that it is pertinent, comprehensive and accessible. A key focus was to catalog the material to ensure its accessibility by the users.
