LCA ANALYSIS

Embodied Carbon Benchmark

After performing an LCA analysis over our building, with the use of the software OneClick LCA, we found a value of 445 kg of CO2/m² of construction. Although compared to general buildings in Italy (Table 10) in a Benchmarking approach, it is positioned in a D classes, it is likely that comparing to Arenas and Sports Hall, its performance would be between the expected range for a low carbon building.

Life Cycle Stage Assessement

As the operational stage was not considered in this LCA Analysis (due to lack of more engineering analysis), most of the result shown below is due to the construction phase of our building. We can see that the most important component for Global warming kg of equivalent CO2 is, though, the production of the materials itself. This may be a result of the use of last longing materials (that require less maintenance and replacement), recyclable materials (that reduce the impact of the end of life) and local producers (which reduce the impact of transportation).

Analysing the construction phase, we see that horizontal systems (slabs, ceilings, roofing decks, beams and roofs) are the major cause of our equivalent CO2 emissions. Vertical Structures are also relevant in this sense. Logically, the biggest volume of materials are also in these systems, but are also these systems that use the major part of CO2 emission villains: Concrete and Steel.
