ISO 15686-10:2010

Overview

ISO 15686-10:2010 - "Buildings and constructed assets - Service life planning - Part 10: When to assess functional performance" defines when functional performance requirements should be specified, verified and audited during the whole life of buildings and built facilities. It is part of the ISO 15686 service life planning series and applies to a single building, a facility within a building (one floor, group of spaces), or a portfolio of holdings. The standard addresses roles across the asset lifecycle - owners, managers, occupants, tenants and other stakeholders - and can be invoked by clients or regulatory authorities.

Key topics and technical requirements

• Timing of assessments: Identifies phases and stages in the whole life during which to compare demand (required functionality) and supply (serviceability/capability).
• Demand vs. supply evaluation: Guidance on when to check capability of buildings and facilities to meet identified functional performance requirements.
• Definitions and scales: Provides terms and definitions (e.g., asset, functional performance, serviceability, level of functionality/serviceability) and introduces the concept of demand and supply scales for rating performance topics.
• Profile and thresholds: Uses profiles of required levels (levels of functionality) and provided capability (levels of serviceability) and identifies gaps and threshold levels that significantly impair use.
• Risk and cost consequences: Directions on estimating risk and life-cycle cost implications due to gaps between demand and supply at different stages (pre-project, pre-construction, construction, operation).
• Updates, audits and review: Recommends frequency and triggers for updating assessments and performing audits during the asset’s whole life.
• Supporting annexes: Informative annexes cover concepts of functionality and serviceability, derivation of life stages, typical actions at each stage, consideration of change vs degradation, and tools to prioritize projects and allocate resources.

Practical applications and users

ISO 15686-10:2010 is practical for:

• Asset and facility managers planning inspections, audits and upgrades to maintain serviceability.
• Owners and property investors assessing portfolio performance and long-term risk.
• Designers and project teams who need to define when performance verification is required.
• Operators and tenants to understand functionality thresholds that affect operations.
• Regulators and clients that mandate performance verification at specific lifecycle stages.

Typical uses include establishing inspection schedules, prioritizing retrofit or replacement projects, assessing obsolescence risk, and informing life-cycle costing and environmental impact assessments when linked to other ISO 15686 parts.
