Written on 21. October 2012.

*Aspect*		B-16 Refurbishment for screening, simplified and complete LCA
*Description*		Refurbishment activities refer to the change of major elements or change of use in a building.Do we need to take refurbishment into account in a building LCA?
*related study objective*		☒ stand-alone LCA		☒ comparative assertion
*related study phase*		☒	☐	☐	☐	☐
		goal and scope definition	inventory analysis (LCI)	impact assessment (LCIA)	interpretation	reporting
*relevant for*
	new buildings	existing buildings	construction products	screening LCA	simplified LCA	complete LCA
*Provisions*	Refer to provisions in the aspect ‘Distinction between Modules B2, B3, B4 and B5’.
*Rules from:*	*EN 15978: 7.4.4.1 General* 7.4.4.6 Boundary for refurbishment (Module B5) 8.3 Time related characteristics 8.6.4 Scenarios for refurbishment *EN 15804:* 6.3.4.4.2 B1–B5 Use stage information modules related to the building fabric: 7.3.3.1 B1–B5 Use stage related to the building fabric
*Guidance*	Refer to guidance in the aspect ‘Distinction between Modules B2, B3, B4 and B5’. For example, it is recommended that a refurbishment scenario be developed in the case of a significant reference study period (>100 years); as modification of the building use is expected over such a period of time. A refurbishment scenario could also be developed if the reference study period is higher than the reference service life of load-bearing components and structural elements.
