481 Prototypical commercial buildings for 20 urban market areas

Abstract

This report documents the methodology used to determine the load patterns and estimate the building populations for various commercial and multi-family buildings in 20 representative markets of the US. The task involved describing nearly 500 prototypical buildings by building type, vintage, and city, defining their internal conditions and operating schedules, and then simulating their hourly energy profiles using the DOE-2.1D building energy simulation program. The simulated energy usages were than calibrated against statistical data and the building descriptions modified to better correlate to measured energy and end-use intensities and fuel/electric ratios. A secondary task involved using statistical data on construction activity and surveys to estimate the numbers and total floor areas represented by each of the prototypical buildings. The primary objective of this project is to supply input information on building loads and market sizes for a microcomputer program. The purpose of this program, here referred to as the Commercial Cogeneration Assessment Model (CCAM), is to assess the potential of cogeneration in commercial and multi-family buildings from the present to the year 2000. A secondary objective for this project is to provide a large data base of hourly load profiles for prototypical commercial buildings that can be used for othermore » technical studies. Detailed descriptions of the data output are given. 50 refs., 5 figs., 126 tabs.« less
