ISO 37155-2:2021

Overview

ISO 37155-2:2021 provides a holistic framework for the integration, development, operation and maintenance of smart community infrastructures. The standard addresses interactions between multiple infrastructures, stakeholders and the external environment to ensure consistent, system-level performance of smart community solutions. It is framed as a management case (specific processes to follow), not a management system, and supports two primary use cases:

• Greenfield: coordinated design and deployment of all smart community infrastructures for new developments (of interest to planners and investors).
• Brownfield: retrofitting and managing existing urban areas by accounting for growing interdependencies across infrastructures.

Keywords: ISO 37155-2, smart community infrastructures, holistic approach, system of systems, integration, lifecycle.

Key Topics and Requirements

ISO 37155-2 structures guidance around a clear set of technical topics and lifecycle requirements:

• Layered view of infrastructures - system layer, infrastructure layer, and sub-infrastructure layer to clarify scope and responsibilities.
• Life cycle phases - initiation, concept, design (basic concept, plan, fundamental and implementation design), tendering, construction and assessment, operation & maintenance, redevelopment/rehabilitation, and decommissioning.
• Consistency process - a V-process and general process model to set targets, analyze solutions, verify/validate functionality, monitor performance and drive improvements.
• Verification and validation guidance - phase-specific recommendations to ensure that both individual subsystems and the integrated system meet community objectives.
• Roles and responsibilities - allocation of accountability across community authorities, investors, developers, operators and service providers.
• Adaptation drivers - consideration of accelerating technological change and environmental factors when planning and operating infrastructures.

Keywords: verification and validation, lifecycle phases, consistency, V-process, stakeholders, interoperability.

Practical Applications and Who Uses This Standard

ISO 37155-2 is practical for organizations involved in planning, financing, designing, operating or regulating smart community projects:

• Planners and investors evaluating coordinated greenfield developments or large-scale urban projects.
• City and community authorities managing brownfield upgrades and strategic urban resilience.
• Developers, infrastructure owners and operators seeking to align multiple systems (energy, mobility, water, ICT) as a system of systems.
• Service providers and integrators responsible for cross-domain interoperability, performance monitoring and maintenance strategies.
• Lenders and risk assessors requiring structured evidence of system-level consistency and validation.

Typical uses include designing a new smart district, integrating legacy systems into a digital urban platform, or establishing lifecycle-based operation and maintenance plans.

Related Standards

ISO 37155-2 is complementary to other ISO and IEC work on sustainable cities and infrastructure domains. It intentionally focuses on cross-infrastructure consistency and does not duplicate standards addressing individual infrastructure sectors (energy, transport, water, ICT). For comprehensive implementation, combine ISO 37155-2’s system-level framework with sector-specific standards and technical guidance.
