Copyright 2018 ASHRAE. The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE)/Chartered Institution of Building Services Engineers (CIBSE)/U.S. Green Building Council (USGBC) performance measurement protocols provide a standardized set of protocols for measuring and comparing the operational performance of occupied commercial buildings. The ASHRAE performance measurement protocols have been developed at three levels of cost/accuracy, Basic (Indicative), Intermediate (Diagnostic), and Advanced (Investigative), for the following six performance categories: energy use, water use, thermal comfort, indoor air quality, lighting, and acoustics. This article presents the results of an effort to develop and apply a field test to evaluate the Advanced level of the performance measurement energy protocols in a case-study office building in Central Texas. The data collected include multi-year sub-hourly whole-building electricity data for the total and major end uses, thermal data for chillers and condensers, and coincident on-site weather data, as well as monthly utility bills of the case-study building. The data collected were then analyzed to calculate the corresponding performance metrics based on the Advanced level of the performance measurement protocols energy protocols and compared with the appropriate benchmarks. The problems and issues with implementing the performance measurement protocols Advanced level energy protocols in a case-study building were noted throughout the entire research process. The evaluation revealed four issues, for each of which recommendations were developed to improve the current version of the performance measurement protocols. The results for the performance measurement protocols Basic level applications, including all six areas, were reported in Kim and Haberl (2012a). A companion paper (Kim and Haberl 2017) presents the results of applying the performance measurement protocols Intermediate level energy protocols.
