This paper analyzes the Spanish housing demand for electricity, natural gas, liquefied petroleum gas (LPG) and liquid fuels using a QUAIDS model. Since not all households consume all fuels at a time, this model is adapted to consider censored data. The data used belong to the Spanish Encuesta de Presupuestos Familiares (EPF) of 2013. The results indicate that the demand for electricity and liquid fuel have inelastic price elasticity, while natural gas and LPG are sensitive to changes in demand prices. Furthermore, all fuels are normal goods, although the demand for LPG is the most sensitive to changes in household income.

Key words: residential energy demand, QUAIDS model, censoring.
