Material, energy, water use and occupation land related to construction industry activities represent a major contribution to the total environmental impact caused by society. In fact, it is estimated that the building sector is responsible for the 30–40% of the society’s total energy demand and approximately 44% of the total material use. Consequently, the building sector has to be prioritized to be able to reach a sustainable society within a reasonable period of time. The present work is included in the context of the assessment of sustainability of construction sector and is aimed at analyzing and quantifying the environmental impact of its related activities at different levels of analysis of the building industry. In detail, the environmental performance is performed by means of a Life Cycle-oriented approach. Two main approaches of Life Cycle Assessment (LCA) for construction applications have been considered: i) LCA for Building Materials and Component Combinations (BMCC), i.e. focusing on building materials, and ii) LCA of the Whole Process of the Construction (WPC), i.e. considering entire building system or sub assemblages. The approach i) has been applied to evaluate the environmental footprint of recycled and natural concretes. The main purpose has been the computation of the environmental impact of the conventional and innovative building materials in order to quantify the potential environmental benefits (e.g. in terms of CO2 emissions, raw material usage, waste recycling etc) of new (innovative) solutions. LCA has been also implemented to evaluate the environmental profile of different retrofit solutions on existing buildings, using approach ii). This work has investigated possible design alternatives for retrofit/renovation operations when structural/functional requirements have to be fulfilled. In detail, the environmental impact of different design options for a typical structural retrofit operation conducted on masonry and reinforced concrete buildings have been assessed. The scope of this thesis is to illustrate several comprehensive LCA-based approaches that could be effectively used to drive the design of new and existing buildings. The final objective of this contribution is to show how a rigorous environmental analysis can influence decision-making in the definition of the most sustainable design alternatives. The designers can monitor the environmental impact of different design strategies in order to identify the most suitable option.
