COMPARISON OF TWO DIFFERENT SIMULATION PROGRAMS WHILE CALIBRATING THE SAME BUILDING
Sukreet Singh, Andrea Martinez, Karen Kensek, Marc Schiler
An existing institutional building of 95,287 square feet was calibrated for energy usage using Design Builder and eQuest. The whole building simulation models were made based on precise building geometry, occupancy, and equipment power and lighting densities. Building schedules were input to more closely relate the digital model to the actual building’s use (occupancy, heating, cooling, lighting, and ventilation), and some on-site measurements of plug loads were taken. Load balance, sizing of systems, electrical and gas consumption, and end uses of fuel consumption are compared. This paper explores the differences between the outputs and workability of both simulation tools. process, the main differences in modeling and simulating in the two software programs were observed and documented.
