Abstract
A role of ACLD and ACSS as the energy simulation program is described. And their basic mathematics models, such as a time average model and relation of a load calculation and simulation are described. A way of thinking of a method to integrate similar programs derived in various ways in one core solver, and some problems when integrated for future extensions, an interval for 15 minutes, air flow window systems , thermal storage using a structure body, a problem of weather data and a diversity factor of inside heat generation are described.
