Abstract
The buildings sector is a major energy consumer, accounting for about 40% of total EU energy consumption so more than any other single sector they are in the front line for potential energy saving. This thesis is written on the background of European Union's Directive on Energy performance of buildings. The aim of this thesis is to find out the energy consumption profiles and indicators in the European buildings. First the overview of energy use in building is described. Then the scope of energy saving in the buildings sector and possible measures to realize the large potential here is discussed. There are many possibilities for the future for the efficient use of energy and they are economically viable. After that the available directives and regulations as well as programmes for the efficient use of energy are presented. Next the energy efficiency calculation methods are studied. As a practical application, electricity used in the `Light House' for lighting and electrical appliances are calculated and the result is compared with the other buildings. It is found that the Light House is using very efficient lighting equipments and applying daylighting and control system. So it is very efficient in energy use. Also the electrical appliance equipments are using energy efficiently compared to other buildings. So by the use of more efficient equipments and technologies, electricity efficiency of the buildings can be improved greatly.
