BAXI WALL HUNG CONDENSING BOILER LUNA 4

ENVIRONMENTAL PERFORMANCE DECLARATIONMETHODOLOGYThe environmental performance of the considered system has been quantified by Life Cycle Assessment(LCA) approach in accordance with ISO 14040 series. Data used for the study refers to year 2007, dataconcerning the boiler are representative of the product. Specific and generic data fulfill General ProgramInstruction criteria for EPD.The use phase has been modeled by averaging space heating and hot domestic water production with nooverlapping.Space heating takes into consideration a residential house with the following characteristics:FeaturesNet Area 160 m 2Heat Load (Net energy requirement index)Heating seasonWorking definitionRegimeInternal temperature (day‐time) 25 °CInternal temperature (night‐time) 21 °CMarket100 kWh/m 2 ∙yearFrom September to May (273 days)24 hours per dayNot continuous (soft in night‐time)EU (average of 27 Countries)Hot domestic water data are from test according EN 13203-2 Cycle 4 (the heaviest cycle fulfilled by theboiler).FUNCTIONAL UNITThe functional unit (F.U.) for this analysis is defined as 1.000 kWh of net thermal energy available balancedamong Domestic Hot Water and Heating Generation during a standard production cycle.5
