1. Scope

1.1

This Guideline considers the agents and mechanisms related to durability and provides advice for incorporating requirements for durability into the design, operation, and maintenance provisions for buildings and their components.

1.2

The Guideline includes (a) definitions of performance, failure, service life, and other concepts related to building durability; and (b) guidance for designers, builders, owners, and operators on achieving durability by planning the design, construction, maintenance, repair, and renovation of buildings.

1.3

The durability of mechanical and electrical systems and services in buildings is not within the scope of this Guideline. Notes: (1) While not addressed specifically, it is recognized that durability of these systems and services should be included in an integrated design. The principles set forth herein may be considered for application to a building's systems and services provided the effects of internal loads resulting from their operation ar e also taken into appropriate account. (2) The loads on components and the building that result from the operation of the systems and services should be considered along wit h environmental and structural loads.
