The program, SPIEL-JRC, was conceived for the assessment not only of energy consumption (thermal and electric) but also of the energy savings of various Energy Conservation Opportunities (ECO). In order to minimise the building envelope and various plants (HVAC, cooking, electricity) input data, the program makes extensive use of default data stored in associated files. Different default data are available according to the building category (residential, school, office, etc.) and plant types. Many algorithms in the program are the result of empirical analyses of a considerable amount of real data. The program can simulate up to 300 different combinations of building uses, fuel and emitter types, heating and cooling modes, and control schemes. A building can be simulated iteratively with different configurations of building elements, plant types, and users' behaviour. SPIEL-JRC can simulate up to 8 building zones (on an hourly basis) by means of a lumped parameter R-C model. The thermal balance is described by differential equations with the node temperatures as unknown variables and which are solved with a finite difference algorithm having an integration time step which is automatically determined and optimised.
