The primary objective for the research which this report describes was to compare the results predicted by a microcomputer based simplified energy analysis to those obtained by the DOE-2.1 program. The ASEAM computer program, as developed, utilized the methodology and algorithms from the proposed ASHRAE TC 4.7 Simplified Building Energy Calculation Procedure pertaining to the buildings' envelope, internal loads and operating profiles. This methodology was also utilized for the weather data bin temperature processor that is used in the program. The algorithms for the eight mechanical heating and cooling systems in the program were developed as a modification, and extension to the TC 4.7 method, using existing manual bin procedures and standard engineering equations. The heating and cooling plant routines incorporate part load ratio curves as utilized in the DOE-2 computer program for the various chillers, boilers, furnace and unitary equipment. The overall structure of the plant routines follow the simplified bin methodology. These modified system and plant algorithms were therefore the major area of investigation and study. Over fifty comparisons were performed primarily to simulate the various mechanical systems with different plants while varying system parameters including percentage of fixed outside air, outside air economizer cycle, supply air discriminator control reset and heating humidification. The building envelope parameters that were tested were the simulation of window shading overhangs, reduction of the floor weight of the building construction and a variation of the percentage of glazing on all exposures. The building type used in the testing was a one story medium office building that was zoned in three configurations of one, two and five mechanical zones. Washington, DC was the selected city for the simulations.
