THE SIGNIFICANT FACTORS IN MODELLING RESIDENTIAL BUILDINGS: PART 2
Julia Purdy, Ian Beausoleil-MorrisonAbstract: For users and developers of energy simulation soft ware tools, knowledge of which inputs have the great est impact on the simulation results will dictate which areas of the building require additional development and input time. This is the second reporting of a study examining the sensitivity of simulation results to modelling assump tions and user inputs. In this case, the sensitivity of the HVAC system's energy consumption to various furnace inputs, and the impact of the internal condi tions on the annual heat load are examined. The predicted furnace energy consumption was found to be sensitive to the simulated efficiency and the part load curve. The convective/radiant ratio of heat injec tion, and the set-point and setback temperatures had the greatest impact on the predicted heating load. Paper:esim2001_28
