ANSI/ASHRAE/IES Standard 100- 2015, Energy Efficiency in Existing Buildings, provides comprehensive and detailed descriptions of the processes and procedures for the retrofit of existing residential and commercial buildings in order to achieve greater measured energy efficiency. Appendices are included for life-cycle cost analysis procedures as well as identification of potential energy con- servation measures. "The total primary energy used in both residential and commercial building sectors is expected by the U.S. Energy Information Administration to rise each year for the next several decades in spite of aggressive efficiency improvements in new construc- tion," Rick Hermans, chair of the Standard 100 committee, said. "In order to reduce the overall impact of energy used by residen- tial and commercial buildings, the existing building stock must become more efficient. This revision to Standard 100 provides the means to accomplish that goal." The standard addresses both residential and commercial buildings. It addresses single and multiple activity buildings with variable occupancy periods and identi- fies the approach for 53 building types in 17 climate zones/subzones. It identifies requirements for buildings undergoing retrofits that do not fall under the scope of either ANSI/ASHRAE/IES Standard 90.1-2013, Energy Standard for Buildings Except Low-Rise Residential Buildings, or ANSI/ASHRAE/IES Standard 90.2-2007, Energy Standard for Low-Rise Residential Buildings. Standard 100 directly addresses a build- ing's energy-use efficiency in a quantitative manner and provides a means to improve that efficiency with an objective bench- mark created with the assistance of the Energy Information Administration, the Federal Energy Management Program and Oak Ridge National Laboratory. Recognizing that the actual occupancy of the building plays a key role in its per- formance, the standard establishes the need for development of an energy management plan and an operation and maintenance program. It also addresses the requirements for ongoing commissioning. The standard takes advantage of the fact that any building that has been in operation for at least twelve months can quickly determine its performance rela-
