The Simulation Problem Analysis Kernel (SPANK) was originally described as a prototype Energy Kernel System in a paper presented at the Second International Conference on System Simulation in Buildings in 1986. Since that time, it has undergone several enhancements and has been integrated into a larger software system that may be more properly called a prototype Energy Kernel System for building energy analysis, EKS/US. Among the enhancements is the capability to simulate dynamic problems. Also, symbolic manipulation techniques are now used to generate objects and macro objects from equations expressed as text. Currently underway is the development of a graphical user interface. Newer developments include a reevaluation of a semantics of dynamic problem definition, which will ultimately result in much greater generality in user specification of numerical methods. This paper reports on these developments and indicates directions for future EKS/US development.
