The existing buildings: A new approach to the energy analysis

Existing building and their retrofitting provides by a far largest potential for the incorporation of renewable energy technologies and efficiency measures into building. Within many European countries there is a considerable higher activity in retrofitting and reusing buildings, than m constructing new ones. Goals of the work are: (.)to improve the energy knowledge in the existing building (.)to develop-a practical assistance and guidelines to improve the understanding and knowledge on the building energy behaviour (.)to define the methodology of approach in the energy analysis of the existing buildings to assist designer for the better integration of recent research results on passive solar and energy efficient technologies. The aim of this work is to illustrate a methodology of approach in the energy analysis of the existing buildings in order to contribute to energy saving of the conventional sources and to promote the cost effective implementation of passive solar and energy efficiency retrofitting measures.
