Origins of whole-building energy simulations for high-performance commercial buildings: Contributions of the 1975 ASHRAE algorithms for heat balance-based hourly heating and cooling load calculations
This study performs a detailed review of the 1975 ASHRAE LOADS algorithms and clarifies their significant contributions to the field of building energy simulation programs that first provided a publicly available heat balance-based hourly load calculation procedure for building energy analysis. The use of the Heat Balance Method in conjunction with the Conduction Transfer Functions Method for the hourly load calculations that was first proposed and developed in these ASHRAE algorithms is still widely used in today’s building energy simulation programs, such as the EnergyPlus and TRNSYS programs. In addition, the Heat Balance Method in these ASHRAE algorithms that was developed for designing and analyzing the whole-building thermal mechanisms became the basis of the current Heat Balance Method for building energy analysis. Based on the analysis of these ASHRAE algorithms and relevant documents, this study also finds their significant contributions to developments of the first generation of the heat balance-based building energy simulation programs in the 1970’s that became the basis of today’s building energy simulation programs. In the other work (Ahn and Haberl 2024), contributions of the 1968 and 1971 ASHRAE LOADS algorithms for weighting factor-based hourly heating and cooling load calculations are reviewed.
