The standard of living in a country is strongly correlated to the energy consumption, hence a considerable increase in the global energy use is expected. The effects of energy conversion on the climate, e.g. increased CO2 level, is already observed. Thus it is imperative to base future energy conversion on resources that have negligible climate effects; solar energy is perhaps the most important of such resources. The general structure of models for solar heating of buildings, with disturbances and relevant sensor technology is described. Simple models of the various parts of the system are developed, and the model is validated through simulation. Requirements for models for on-line control and optimization are discussed. It is noted that ventilation leads to an important energy loss if energy is not recovered by heat integration. The main contribution in this paper is in putting together submodels from different fields and publications into a relatively complete model structure for control of a residential building. A second contribution is the discussion of key disturbances in the system.
