The aim of this project is to calculate the total environmental impacts of a building during its life cycle, and compare which of the three phases of this life cycle (construction, operation and demolition) consumes the most. Reading through literature about this subject [11, 12, 13] I found out that the phases of construction, demolition and relative transportation of materials, all show that the sum of the energy needed for these phases either is negligible or settled at approximately 10-20 % of the total life cycle energy need. I found this huge, since being the phase of operation the one with the highest percentage (80-90%), and the one which we can decrease the most by improving the energetic efficiency of the buildings.
