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.
