It represents the preliminary phase in which the goal of the study, the functional unit, system boundaries, categories of information, assumptions and limitations of the study are defined Life Cycle Inventory. Represents the most important phase of the study. It covers the collection of information and calculation procedures. The goal is to provide a model description with consumption of raw materials and energy production and waste discharges. Typically, a software is used to implement the model and to provide a database of information. Life Cycle Impact Assessment. It is the phase in which the inventory results are translated into a form that they can be more directly related to environmental and human health. Life Cycle Interpretation. Represents the final phase of the study. The inventory results and analysis of impacts are combined according to the objectives and scope of the LCA in order to formulate conclusions and recommendations. If a possible improvement on the system analyzed emerge, the inventory should be rerun to verify the changes implemented are able to effectively ensure the expected benefits.

PURPOSE AND SCOPE DEFINITION OF THE OBJECTIVE AND SCOPE "The objective and scope of an LCA must be clearly defined and be consistent with the intended application" [UNI EN ISO 14040:2006, Par 5.1]. The main objective of this study is the quantification of resources and energy consumption and emissions of substances potentially harmful to humans and the environment resulting from the analysis of life cycle sheds investigated. This report is strictly confidential DEFINITION OF THE FUNCTIONAL UNIT "A functional unit is a measure of functional performance of the outflow of the product system. The main purpose of the functional unit is to provide a reference to which to link the inflows and outflows. This reference is necessary to ensure the comparability of the results of an LCA " [UNI EN ISO 14040:2006, Par. 5.2.2] The functional unit is represented by 1 m 2 of industrial building SYSTEM BOUNDARIES The system boundaries define the process units to be included in the system. Upstream module Extraction and production of raw materials and basic materials Production of fuels, heat, electricity and gas Production of auxiliary materials for the assembly and processing of the shed Transport of components from suppliers to the Company's interest Production of waste in the upstream phase Data on fuel consumption and emissions of the plant involved refer to the year 2010. The production of materials for maintenance, production of materials for plant maintenance and their transport, combined transport of windows has been excluded from the study. Core module Electricity, heat, smoke and auxiliary materials used for the assembly and processing of Building Transport of components from the factory to the customer Downstream module Power consumption for operation of the lighting of the shed for the duration of the life cycle, set equal to 50 years

GENERAL DESCRIPTION OF THE LIFE CYCLE INVENTORY "The inventory analysis includes data collection and calculation procedures that allow to quantify the inflows and outflows of a product system" [Par. 5.2.1 UNI EN ISO 14040]. The life cycle inventory is made with the main purpose of defining and reconstructing all flows of inputs and outputs related to different stages of the production system under consideration, through all the processes of transformation and transport. Make an inventory life cycle means, therefore, build the model analogue of the real system to be studied. Through this activity, are then identified and quantified the consumption of natural resources (raw materials, water), energy (thermal and electric) and other materials (auxiliary, recycled products), which together with air emissions, water and soil, come to structure a real environmental balance, organized in four modules provided by the LCA, according to the diagram in Figure 4.1.

Components transport As regards transport for the delivery of components, suppliers were asked to indicate the length of the path from the site of production to the delivery site, and the medium truck used. The data are as follows: Building A Aggregates: 22 trips (30 km) for the transportation of 550.000 kg Cement: 4,5 trips (100 km) for the transportation of 135.000 kg Steel: 1,5 trips (200 km) for the transportation of 45.000 kg Do not have data transport on the remaining raw materials Building B * Cement: 200 ton (30 km) for the transportation Aggregates: 1000 ton (10 km) for the transportation Iron: 59 ton (80 km) for the transportation Fluidifying: 2800 l (80 km) for the transportation Do not have data transport on the remaining raw materials Exclusions In the following form were excluded the following operations: Production of raw materials needed to construct the lighting system Production of materials for maintenance of the lighting External Transportation for the lighting and windows * the distances are average distances, in Shed B there were given the n transport, but for the purposes of the calculations used only the total ton * km

Core module Construction of Shed The production process is typical of structural precast plants. Starting from concrete, aggregates, additives and water is produced in the concrete batching plant and transferred production lines, by means of wagons traveling by rail air. Before the concrete is cast in molds, these reports are prepared by spraying the drawer that is on a counter-mold release oils that improves the stripping of the building at the end of the curing stage. Once the formwork has been prepared, they are put on the armor and armor-tensioning lens, as well as built-in special. The fixtures are shaped lens through the use of stirrup, claw and hair nets. These machines are suitable for the production of new steel grades with high ductility, provided by the recent antiseismic regulations. The artifacts after casting and vibration of concrete formwork to remain within the time required, so that the concrete reaches the strength required to be deformed. After stripping, these are transferred to the storage area, which are then loaded onto trucks for transport on construction sites where they are mounted. The cycle is then complete with the phase of transport and assembly of manufactured goods in the shipyards and the construction of a series of complementary works through the use of semi-finished products and services provided by outside companies. The consumption of plant that have been reported for the calendar year 2010 were as follows: Building A Electricity consumption: 104,692 kwh Fuel consumption: 36,000 l Both values were spread over the total volume of goods produced in the same year, that is equal to 6.325 m3; By the volume of Shed manufactured of 316.95 m3 are resulted the following values: Electricity consumption: 5,246.186 kwh Fuel consumption 1,803.98 l distributed as: o o 85% attributed to the phases of Assemply (60%) Transport (10%) e Disassembly (30%) * 1.533,39 l 15% attributed to the phases Production 270,60 litri * Fuel for the disassembly phase is due to step down-stream

Building B Electricity consumption: 7.200 kwh Fuel consumption: 1500 litri Methane cosnumption: 4 m 3 Here the values we have been provided already with the criterion of the allocation made; The breakdown of oils and believed to be the same as a percentage of the previous case, namely: o o 85% attributed to the phases of Assemply (60%) Transport (10%) e Disassembly (30%) * 1.275 l 15% attributed to the phases Production 225 litri Transport components Core phase also includes the final transport of manufactured goods to the customer, this is accomplished: For the Building A with 26 trips, for the transportation of about 30,000 kg and an average distance from the customer estimated in 200 km For the Building B with One trips of 2,274,000 kg for an average distance of 200 km * Fuel for the disassembly phase is due to step down-stream The distances are average distances; in Shed B there weren t given the n transport, but for the purposes of the calculations used only the total ton * km

Downstream module Exercise Once delivered, the Shed comes into operation; it was then estimated, based on its current square footage and UNI EN 15193 of March 2008, an electricity consumption for its total life cycle instead of 50 years. The rule that introduces the indicator LENI (Lighting Energy Numeric Indicator) which quantifies the actual energy consumption in kilowatt-hours per square meter/year. The Class (1 to 3) choice for our application is the 1 "fulfillment of basic requirements" for which the indicator LENI is equal to 37.5 kwh/(m2 year) *. Multiplying this value for the 1,500 m2 of floor space and years of life estimated at 50 to get a consumption of 2,812,500 kwh/life cycle of electricity to the shed A and 4,687,500. kwh/life cycle of electricity to the shed B. The country where you will find is the Italian one, so the mix of electric power distribution network used in the study will be the Italian one. In addition to the consumption of electricity consumption, there is no other, having considered the shed not heated and not refrigerated. End of Life The Shed was considered recoverable at 100% in the case R=1 where is considered only the transport component to the rehabilitation center and also the fuel needed for its demolition. If R=0 instead of the materials that make up the shed at the dump are considered in their totality, therefore, we consider the transport to the landfill and their disposal. These data were estimated: Building A 26 trips, for the transport of 30.000 kg of artefacts for an average distance from the property to recover estimated in 100 km Diesel fuel for the disassembly phase has been estimated at 460 l Building B One trip of 2.274.000 kg of artefacts for an average distance from the property to recover estimated in 100 km Diesel fuel for the disassembly phase has been estimated at 321,3 l

SimaPro 7.1 Data were analyzed with the software SimaPro 7.1, developed since 1990 from Pré Consulting (NL); It's a professional tool to collect, analyze and monitor the environmental performance of products and services. Easily you can model and analyze complex life cycles in a systematic and transparent way, according to ISO 14040; it is reliable and flexible, tested and used by large industries, consulting firms and universities. With users in over 60 countries, continues to be the most successful LCA software worldwide. In SimaPro Ecoinvent the database is integrated with over 2700 processes, includes the input-output database, containing environmental data for the sector, based on economic flows. In SimaPro data and methods are stored in files called libraries, which you can draw the information needed to compile the inventory. The inventory is the heart of the project, in addition to the inventory, project you can enter all information pertaining to the study, for example, the description of the objectives and processes and the sources from which the data are drawn. The inventory phase is the actual creation of the model of the system under study, according to materials, processes, and to the assemblies. The processes include data input and output, and are called "blocks" that make up the life cycle. The assemblies do not contain actual data but a list of previously defined processes. With an assembly is then possible to model the production phase. The definition of life cycles, that shape the entire product life cycle, from cradle to grave, also include the treatment of waste output from production. A life cycle includes an assembly and, with respect to it, adds processes related to the processing of waste output, energy use, and any additional life cycles, the system under study is particularly complex or have been defined boundaries very large system. The inputs required for the application of the model are: Fuels Energy Raw materials Among the outputs are listed as follows: Waste heat Air emissions Water emissions Solid wastes Products GWP global warming potential AP Acidification Potential

EP Eutrophication Potential Indoor air quality

LIFE CYCLE ASSESMENT In this phase, the inventory results are assigned to impact categories that is known to environmental effects (greenhouse effect, depletion of the ozone layer, etc..). For each category there is an environmental indicator was chosen with the aim to quantify, using appropriate methods of standardization, the entity with which the production process contributes to the effects considered. CHOICE OF IMPACT CATEGORY, CLASSIFICATION AND CHARACTERIZATION The impact categories considered for the purposes of this study and the environmental indicators identified in the following table, are: Table Errore.

CONCLUSIONS The study showed that environmental impacts are greater during the Down-Stream, where the main role is the consumption of electricity that has to illuminate the shed, during the 50-year life cycle. This statement is validated by the following graph where we report a subdivision average percentage of of the impacts of the GWP and of the resources used for conversion processes of energy between the 5 phases most impacting of the two Shed studied both for the case in which all goes to recycling and if all goes to landfill. Greenhouse Effects 1% 5% 3% 1% 90% Concrete Steel Transport to customer E.E. Use Phase Transfer to recovery Resources used for conversion processes of energy 92% 1% 4% 2% 1% Concrete Steel Transport to customer E.E. Use Phase Transfer to recovery During the Up-Stream phase are instead the highest proportions of material resources consumed, as can be seen from the graphs of Chapters 4.3.2 and 4.4.2. Analyzing the results you can notice like the shed with a weight percentage greater of fully recyclable materials such as aluminium is less impactful from the environmental point of view. The first building contains significant percentage differences between them and variables between cases with complete recycling of all materials and the materials sent for landfill. The second shed shows instead differences smaller percentages and more homogeneous with each other between the case with R = 1 and R = 0.
