A data base of hourly building loads has been created using the DOE=2.1Dprogram for 16 prototypical multifamily buildings in 15 U.S. cities. The buildings reflect typical conditions in rnultifamily buildings of various vintages in four U.S. regions, and range from two-story, four-unit brick buildings built with sing~e-pipe steam heat tolarge five-story buildings of more than 30 units with central forced-air systems.

The purpose of the data base is to provide a consistent basis for assessing the performance and plicability of different equipment and conservation measures to the multifamily building sector. The furl data--with hourly heating, cooling (sensible and latent), and domestic hot waterloads and the estimated electric consumption by apartment unit--will be released on floppy disks together with an interactive PC program that will allow users to extract rnonthly totals, binned loads, or hour-of-day profiles, depending on their research interests. A supporting summary report will also be available giving monthly and binned totals and the methodology used in calculating the data base.
