*relevant for*
	new buildings	existing buildings	construction products	screening LCA	simplified LCA	complete LCA
*Provisions*	In the context of simplified LCA, the following items may be neglected upon justification: Production, transportation, waste management, and end of life of ancillary products; Energy and water usage related to the replacement process; Losses of materials during storage, transportation or implementation (if not known). In the context of screening LCA, only the production of the replaced component may be included. Please refer to the aspects “Replacement with complete LCA”, “Replacement with simplified LCA” and “Replacement with screening LCA” for further details.
