Comparative Study of Availability on Energy/Environment Commissioning Using Existing HVAC Simulation Programs for a Model Building
MetadataShow full item record
Results of comparative study for five typical simulation programs (HASP/ACSS, EnergyPlus, DOE-2, Dest and HVACSIM+(J) are discussed using. a certain reference model of an actual building. The maximum and annual cooling and heating loads and annual energy consumption are compared. Efforts were made to make calculation conditions coincide with each other, but it was not always completely successful due to specific character of algorithms included in each program, so that calculation results differed a little with each other and with actual results. Several case studies have been carried out for each program how design parameters and/or control strategies result on energy consumption and/or indoor environment, which proved availability of each program for commissioning use in various phases depending on their characteristics.
