[en] The hospital buildings are among the largest consumers of energy. The need for continued use 365 days a year, 24 hours, and comfort requirements and specific medical services, making them a highly intensive architectural style (Gas Natural Group, 2010). For this reason, to know a value indicating optimal energy consumption would be very useful in determining which hospitals are or are not efficient in this field. However, determining a single value for the whole hospital would not be useful typology. Set the same value for hospitals that offer different services, knowing that some are much more energy intensive than others, or that are far in number of beds, geographic location ... not provide any reliable information efficiency. This thesis aims to demonstrate that the realization of optimal consumption is determined by the characteristics that influence the energy expenditure of each hospital. and, therefore, it is necessary to know. This will establish groups of this type, with common characteristics, which will facilitate comparison. It is considered, however, it is possible to define a common methodology that leads only to obtain this value, although, numerically, will be different for each group, previously defined. Thus, this paper aims to provide information to define, in general, the variables that affect energy consumption of a hospital, so that in future research to establish the different groups of hospitals that share the same value of consumption optimally. Also, the thesis makes a critical compilation of studies that are related to the procurement of this value in the field edificatorio, assessing whether the methodology it can become applicable to the ground before us.

[es] Los edificios hospitalarios son unos de los mayores consumidores de energ?a. La necesidad de un uso continuado los 365 d?as del a?o, las 24 horas, adem?s de los requerimientos de confort y servicios m?dicos espec?ficos, los convierte en una tipolog?a arquitect?nica altamente intensiva (Gas Natural Fenosa, 2010). Es por este motivo que conocer un valor que indique su consumo de energ?a ?ptimo ser?a muy ?til para determinar que hospitales son o no eficientes en este campo. Sin embargo, determinar un valor ?nico para toda la tipolog?a hospitalaria no resultar?a ?til. Establecer un mismo valor para hospitales que ofrecen diferentes servicios, conociendo que unos son mucho m?s intensivos en energ?a que otros, o que distan mucho en n?mero de camas, ubicaci?n geogr?fica,?no aportar? ninguna informaci?n fiable de eficiencia. Esta tesis pretende demostrar que la concreci?n del consumo ?ptimo est? condicionada por las peculiaridades que influyen en el gasto de energ?a de cada hospital. y que, por ello, es necesario conocerlas. Ello permitir? establecer unos grupos, de esta tipolog?a, con unas caracter?sticas comunes, que facilitar? su comparaci?n. Se considera, sin embargo, que es posible definir una ?nica metodolog?a com?n que conduzca hacia la obtenci?n de este valor, a pesar que, num?ricamente, ser? diferente para cada agrupaci?n, previamente definida. As? pues, en este trabajo se pretende aportar informaci?n para definir, de modo general, las variables que inciden en el consumo de energ?a de un hospital, para que, en futuras investigaciones puedan establecerse los diferentes grupos de hospitales que compartir?n un mismo valor de consumo ?ptimo. Tambi?n, la tesis, hace una recopilaci?n cr?tica de estudios que est?n relacionados con la obtenci?n de este valor en el terreno edificatorio, valorando si su metodolog?a puede llagar a ser aplicable al terreno que nos ocupa.
