Overview of Existing Literature On Diversity Factors and Schedules for Energy and Cooling Load Calculations

This paper provides an overview of methods reported in the literature for generating typical load shapes required for the simulation of energy use and peak cooling loads in commercial buildings. It also includes a survey ofavailable databases ofmonitored commercial end-use electricity data, and a review of classification schemes of the commercial building stock. This study was conducted as part of ASHRAE l093-RP whose objective was to identify and utilize the most appropriate methods for developing diversity factors on relevant monitored sets of lighting and equipment data. The paper also provides a discussion of four methods in the literature that were adapted and combined in l093-RP to develop a library ofdiversity factors and schedules, for use in building energy and cooling load simulation programs.
