Compilation of Diversity Factors and Schedules for Energy and Cooling Load Calculations, ASHRAE Research Project 1093, Preliminary Report, Literature Review and Database Search
Abstract
In this report, the first report for the ASHRAE 1093-RP project, we present: (1) our
extended literature search of methods used to derive load shapes and diversity factors in the U.S.
and Europe, (2) a survey of available databases of monitored commercial end-use electrical data
in the U.S. and Europe, and (3) a review of classification schemes of the commercial building
stock listed in national standards and codes, and reported by researchers and utility projects. The
findings in this preliminary report will help us in performing the next steps of the project where
we will identify and test appropriate daytyping methods on relevant monitored data sets of
lighting and equipment (and other surrogates for occupancy) to develop a library of diversity
factors and schedules for use in energy and cooling load simulations.
The goal of this project is to compile a library of schedules and diversity factors for
energy and cooling load calculations in various types of indoor office environments in the U.S.
and Europe. Two sets of diversity factors, one for peak cooling load calculations and one for
energy calculations will be developed.
Description
In this report we describe the related literature for the ASHRAE 1093-RP project. To accomplish this we have divided the previous works into three categories: (1) existing literature on diversity factor and load shape calculations, (2) literature that reports on existing databases of monitored data in the U.S. and Europe, and (3) relevant studies about classifications of commercial buildings. In the literature on diversity factors and load shapes, we covered papers reporting the existence of databases of monitored end-uses in commercial building, methods used in developing the daytypes and load shapes, and what classification schemes were used in the commercial building sector. We report the names of the scholars and energy analysts whom we contacted in the U.S. and Europe, that provided detailed information (in a tabulated format) on existing databases on monitored end-uses in commercial buildings in the U.S. Finally, we summarize the classification schemes of the commercial building sector that are reported in national standards and codes.Collections
