scope:

This part of ISO 15686 establishes when to specify or verify functional performance requirements during the service life of buildings and building-related facilities, and when to check the capability of buildings and facilities to meet identified requirements.¹⁾

This part of ISO 15686 is applicable to any scope of holdings, whether a set (or portfolio) of buildings, a single building (large or small) or a facility which is part of a building (such as one group of spaces, one floor or several floors). It is applicable to the range of roles of stakeholders, from the owners and managers to the occupants, tenants or other users. It is intended to be used with ISO 15686-1, ISO 15686-2, ISO 15686-3, ISO 15686-5, ISO 15686-6, ISO 15686-7, ISO 15686-8 and ISO 15686-9.

NOTE 1 The principles and methods can be applied to a single-family residence, but this part of ISO 15686 calls for greater frequency and extent of assessing demand and supply than is typically appropriate.²⁾

NOTE 2 The application of this part of ISO 15686 can be required by the client or by any entity having authority, including regulatory authority.

NOTE 3 In Table 2, the column entitled "Outputs called for by other parts of ISO 15686" is provided to show how outputs from other parts of ISO 15686 occur at each phase, whether or not this part of ISO 15686 requires action or output

1) International Standards for the determination of levels of functionality (demand) and levels of serviceability (supply) are the responsibility of ISO/TC 59 SC 3.

2) International Standards for the description of performance of single-family residences for the purposes of specifying performance requirements and performance levels are the responsibility of ISO/TC 59 SC 15. Standardization work related to the performance of single-family detached and semi-detached dwellings is reflected in ISO 15928 (all parts).
