<strong>DASTA</strong> – <strong>Work<strong>in</strong>g</strong> <strong>Paper</strong><br />

Environmental impact assessment method The follow<strong>in</strong>g <strong>in</strong>dicators were<br />

used to assess <strong>the</strong> environmental impacts: climate change (kg CO2 eq./m²),<br />

acidification (kg SO2 eq./m²), eutrophication (kg PO4 eq./m²), and nonrenewable<br />

energy (MJ/m²).<br />

Special features The study highlights <strong>the</strong> necessity to use a specific LCA<br />

software for build<strong>in</strong>g design and <strong>the</strong> importance of prevent<strong>in</strong>g environmental<br />

impacts, act<strong>in</strong>g at <strong>the</strong> design phase.<br />

Ma<strong>in</strong> limitations The <strong>in</strong>dicators chosen for <strong>the</strong> characterization phase<br />

referred only to four environmental impact categories.<br />

3.9 LCA of accommodation and spa services of an Italian hotel (Floridia,<br />

2007)<br />

Methodology Conventional LCA.<br />

Products Tourist structures and services of hotel Terme Belvedere <strong>in</strong><br />

Abano Terme, Veneto.<br />

Objectives The objectives of <strong>the</strong> LCA studies are as follows: assessment of<br />

<strong>the</strong> environmental damages generated by a hotel build<strong>in</strong>g along its life cycle<br />

(from <strong>the</strong> construction to <strong>the</strong> change of use, till <strong>the</strong> demolition phase);<br />

identification of environmental hot-spots to def<strong>in</strong>e potential improvement<br />

actions and management strategies for structures and services provided (i.e.,<br />

accommodation and spa services).<br />

Functional unit Because hotels are complicated systems, due to several<br />

processes <strong>in</strong>volved with<strong>in</strong> <strong>the</strong>ir life cycle, <strong>the</strong> authors decided to outl<strong>in</strong>e a<br />

functional unit consider<strong>in</strong>g <strong>the</strong> follow<strong>in</strong>g elements: build<strong>in</strong>g dimension, which<br />

ma<strong>in</strong>ly affects material consumption, management and disposal; number of<br />

tourist stays per year, which are strongly related to operat<strong>in</strong>g stage of hotel<br />

structures; open<strong>in</strong>g period of <strong>the</strong> hotel; life span of structures.<br />

System boundaries The life cycle model was focused on <strong>the</strong> life of hotel<br />

structures from cradle to grave. In fact, <strong>the</strong> follow<strong>in</strong>g phases were <strong>in</strong>cluded <strong>in</strong><br />

<strong>the</strong> system boundaries: extraction of raw materials; manufactur<strong>in</strong>g of build<strong>in</strong>g<br />

products; build<strong>in</strong>g construction; use and management of structures, <strong>in</strong>clud<strong>in</strong>g<br />

activities of hotel ma<strong>in</strong>tenance; end of life of build<strong>in</strong>g materials.<br />

Data quality Primary data on <strong>the</strong> usage of <strong>the</strong> hotel build<strong>in</strong>g for<br />

accommodation and spa services (e.g., consumption of energy, water and<br />

products, and waste production) were collected directly on site. As regards<br />

<strong>the</strong> build<strong>in</strong>g construction phase, architects and technical experts collaborated<br />

to identify materials and to estimate quantities because no bill of quantities<br />

was available. Moreover, energy consumption by <strong>the</strong> mach<strong>in</strong>ery and<br />

equipment used <strong>in</strong> <strong>the</strong> build<strong>in</strong>g yard (e.g., crane, cement mixer, etc.) was<br />

calculated on <strong>the</strong> basis of data sheets and time estimations. F<strong>in</strong>ally,<br />

databases <strong>in</strong>cluded <strong>in</strong> <strong>the</strong> SimaPro 7.0 software, as well as surveys were<br />

used to complete <strong>the</strong> LCA <strong>in</strong>ventory.<br />
