As environmental issues become increasingly important, the buildings have focused on energy efficiency and energy needed for the construction and production of material. This research shows a simplified life cycle analysis study of operational and embodied energy of four new houses located in Temuco - Chile, structured with SIP (Structural insulated panel), in order to quantify the energy at each stage of this construction system. To obtain embodied energy were used two international databases in order to quantify the energy of each material, and the energy contained in the process relating with structure SIP was determined through measures in a company specializing in SIP construction. For the operational energy, computational models were carried out with Design Builder software, and this energy was projected at 50 years lifespan. The analysis of the data obtained show that the energy contained by construction processes represents about 1.7% of embodied energy, while the total embodied energy represents 11% of the total life cycle energy of houses, the remaining 89% represents the energy of occupation. On the other hand, we observe that SIP houses generate figures close to 60% savings in energy demand, compared to a masonry houses commonly built in this city.
