The industry of civil construction is a major consumer of energy and natural resources. In terms of ambiental sustainable, it is necessary to worry about these use because they are finite. Embodied energy is the method of analysis for calculate the energy from processed materials. It includes all the energy of construction cicle: extraction, use and transportation. Building materials embodied energy represents 29% to 49% of all energy consumed by the building in a 50-year life cycle. So, this work presents the calculation of the embodied energy from a residential building using a BIM (Building Information Modeling) software. The studied object is from a social housing program named "Minha Casa Minha Vida", that means "My house, My life" . The theoretical scope of this research was defined as the initial embodied energy of the building. The results was obtained through an existing method from previous studies about energy life cycle of Brazilian buildings. BIM software allow data interoperability and collaboration in projects of different specialties that get results in a automate way. National research provide tables with embodied energy data from the materials used in the building model. Embodied energy is presented by volume (megajoule per cubic meter - MJ / m3) due to the ease obtaining volumes of materials from the virtually constructed model. BIM software was choised because information are incorporated into the geometry of model. After modeling the building, volume data was extracted easily and precisely. They are presented in tables. From this, it is possible to obtain the total embodied energy value of the building. As part of a multidimensional assessment strategy for housing to be built (CADnD), this process measur the building environmental impact and allows comparing design studies enbasing project decisions considering sustainability of housing.
