SAVE stands for Simulation and Analyses of Virtual use in Energyscenarios and will be used for the analysis of future energy savings possibilities for end users, in conjunction with volume growth and structural changes in the socio-economic system. The model contains different sectoral modules. Within the module one can discern the hierarchical levels sector, segment and function. SAVE Utility Buildings uses mostly standard energy functions, such as space heating, hot water supply, cooling, lighting and appliances. The energy use, excluding savings for each energy function, depends on a set of economic, demographic, physical, etc., variables. A number of savings measures attached to each function can decrease energy demand. With regard to energy a distinction is made between electricity and fuels/hot water. These are also translated to primary energy use. A vintage approach is used to describe the (slow) effect of new energy saving offices, the saturation effects with insulation of old buildings and the time dependent restrictions for penetration of saving measures. The capacity of all energy using 'systems' (buildings, boilers and appliances) in different years has been modelled. These vintages are renewed by scrapping of old items and buying new, probably more efficient, ones. The model uses a base year (1990) and a number of case years (1995, 2000, 2005, 2010 and 2015). Savings are split up with regard to investment needs (from good housekeeping to new energy efficient houses), the technical or behavioral nature and the degree of energy policy influence. Decisions on the penetration of saving measures are in principle based on cost/benefit ratios, except in the case of standards. In the analysis account is taken of subsidies, tariff structures and taxes and other mitigating factors. The results comprise the future use of different energy carriers and the change over time of primary energy use split up in a volume, structure and saving effect. For each saving measure the penetration level and costs are available.
